Frequently Asked Questions(FAQ)

What are the key differences between the 806-022-MT14-7FTF and other 7-position circular connectors when selecting for high-temperature aerospace applications?
The 806-022-MT14-7FTF from Glenair's Mighty Mouse 806 series distinguishes itself through its operating temperature range of -65°C to 200°C, which exceeds many standard circular connectors rated only to 125°C or 150°C. This extended upper limit makes the 806-022-MT14-7FTF particularly suitable for engine bay, avionics, and thermal management applications where ambient or radiated heat reaches elevated levels. The aluminum shell with nickel/PTFE finish provides corrosion resistance in harsh environments, while the gold-plated mating contacts (50µin thickness) ensure reliable signal integrity across thermal cycling. The 5A current rating per contact accommodates moderate power distribution without requiring larger connector formats.
Why would an engineer choose solder cup termination on the 806-022-MT14-7FTF instead of crimp or IDC options?
Solder cup termination on the 806-022-MT14-7FTF eliminates the need for specialized crimping tools and applicators, reducing assembly process complexity and inventory overhead. Solder joints provide a permanent mechanical and electrical connection that is inherently repeatable across different assembly environments—particularly valuable in aerospace where traceability and reproducibility are critical. The 806-022-MT14-7FTF's solder cup design allows field repair and rework without connector replacement, an advantage when managing legacy systems or in remote deployment scenarios. Solder termination also accommodates wire gauges with greater flexibility than crimp contact sizing, allowing designers to match wire cross-section directly to thermal and current requirements without constraint from a limited matrix of crimp tool sizes.
How does the panel-mount flange configuration of the 806-022-MT14-7FTF affect shielding and environmental sealing in enclosure design?
The 806-022-MT14-7FTF uses a threaded panel-mount flange that mechanically secures the connector to the enclosure wall through a nut, creating a defined mechanical datum that simplifies alignment and reduces vibration-induced microphony. The through-hole mounting style and flange interface establish a physical reference plane that supports repeatability across production units. Although the 806-022-MT14-7FTF is specified as unshielded, the aluminum flange and shell assembly provide some level of RF containment through structural shielding at frequencies below a few hundred megahertz. For applications requiring active electromagnetic shielding, the threaded interface of the 806-022-MT14-7FTF allows integration with optional shielded backshells. The flange geometry also creates a shoulder that limits panel thickness to approximately 0.25–0.375 inches, a constraint that must be verified during enclosure design.
What contact material composition in the 806-022-MT14-7FTF supports long-term mating cycle life without degradation?
The 806-022-MT14-7FTF employs copper alloy contacts finished with 50µin (1.27µm) of gold plating on the mating surfaces. Copper alloy substrates provide excellent electrical conductivity and mechanical spring properties, while gold plating isolates the copper from atmospheric corrosion and prevents oxidation-induced contact resistance increases. The 50µin thickness is substantial enough to survive approximately 50–100 mating cycles before plating wear exposes the copper substrate, depending on contact force and connector design. This specification places the 806-022-MT14-7FTF in the medium-duty connector class, suitable for applications with infrequent field disconnection (such as engine compartment harnesses or panel-mounted flight instrumentation). For applications requiring thousands of mating cycles, thicker gold plating or palladium-nickel overlays would be necessary, but would increase cost beyond the 806-022-MT14-7FTF specification.
How do the thermal properties of the 806-022-MT14-7FTF's aluminum shell and nickel/PTFE finish affect connector reliability during rapid temperature transients?
The 806-022-MT14-7FTF uses a pure or 6061-series aluminum shell with a nickel/PTFE composite finish. Aluminum exhibits a coefficient of thermal expansion (CTE) of approximately 23 ppm/K, significantly higher than steel (12 ppm/K) or copper (17 ppm/K). During rapid thermal cycling—such as a 100°C per minute ramp from -65°C to 200°C—the aluminum shell of the 806-022-MT14-7FTF expands and contracts more aggressively than the solder cup contacts and internal inserts. This CTE mismatch creates cyclic shear stress at the solder interface and between the shell and insert materials. The nickel/PTFE finish reduces but does not eliminate this effect; it primarily provides corrosion resistance and low friction during assembly. Designers using the 806-022-MT14-7FTF in applications with temperature ramps faster than 50°C/minute should perform thermal cycling qualification (IPC-TM-650 2.6.7 or equivalent) to validate solder joint fatigue life.
Can the 806-022-MT14-7FTF be used in medical implant or FDA-regulated device applications, and what compliance documentation is required?
The 806-022-MT14-7FTF carries RoHS Not Applicable status, indicating it was manufactured under legacy processes that may include restricted substances such as lead in plating or solder, or cadmium in certain finishes. This designation disqualifies the 806-022-MT14-7FTF from direct use in many medical device applications requiring RoHS compliance or biocompatibility assessment under ISO 10993 or IEC 61010-1. The nickel plating on the 806-022-MT14-7FTF shell introduces a biocompatibility concern; nickel sensitization affects approximately 10–15% of the population. REACH compliance is listed as Unaffected, meaning the connector contains no SVHC (Substances of Very High Concern) under current REACH annexes, but this does not address device-level regulatory pathways. Medical device designers considering the 806-022-MT14-7FTF would need to either source a medical-grade variant with documented biocompatibility testing or select an alternative connector with explicit medical device certification.
What is the mechanical durability specification for the threaded coupling mechanism on the 806-022-MT14-7FTF, and how does it compare to bayonet-style connectors?
The 806-022-MT14-7FTF employs a threaded fastening system that requires approximately 10–15 rotational cycles to mate and demate fully. Standard threaded connectors are typically rated for 500–1000 mating cycles before thread wear necessitates replacement, depending on material hardness and assembly torque. Threaded couplings on the 806-022-MT14-7FTF distribute mechanical load across multiple thread pitches, making them more resistant to accidental loosening from vibration compared to single-bayonet systems, which rely on friction or detent mechanisms. However, threaded systems on the 806-022-MT14-7FTF require longer dwell time during connection, making them unsuitable for rapid-connect applications in combat vehicle or aircraft preflight scenarios. The aluminum shell of the 806-022-MT14-7FTF is softer than stainless steel or beryllium copper alternatives, so repeated coupling and decoupling with excessive torque (above 5–7 inch-pounds) can damage threads. Designers should specify coupling torque limits in assembly procedures to maximize the service life of the 806-022-MT14-7FTF.
How does the current rating of 5A per contact on the 806-022-MT14-7FTF translate to practical power distribution in aerospace wiring harnesses?
The 806-022-MT14-7FTF specifies 5A per contact at unspecified ambient temperature (likely 70°C reference per MIL-DTL-38999 conventions). With 7 positions, theoretical maximum continuous current is 35A across all contacts, but this assumes equal current distribution and no thermal derating. In aerospace harnesses, actual derating factors typically reduce this by 20–30% to account for connector insertion loss (typically 2–5 mΩ per contact for gold-plated surfaces), contact resistance buildup from thermal cycling, and localized heating in the connector body. Therefore, the 806-022-MT14-7FTF is realistically capable of delivering 24–28A continuous across all 7 contacts without exceeding 85°C connector body temperature in a 55°C ambient cabin environment. For engine bleed air ducting applications where ambient reaches 120°C, further derating (additional 15–20%) applies. High-current distributions above 3–4A per individual contact should incorporate forced air cooling or thermal analysis to verify that contact resistance heating does not degrade connector reliability.
What environmental protection does the 'Environment Resistant' ingress protection rating provide for the 806-022-MT14-7FTF in unmated conditions?
The 806-022-MT14-7FTF lists ingress protection as 'Environment Resistant' rather than a specific IP rating (such as IP67 or IP68). This descriptor indicates the connector meets general environmental exposure resistance but does not guarantee submersion, salt-fog, or pressurized wash protection without a mated backshell or dust cover. The nickel/PTFE finish on the aluminum shell resists corrosion from humidity and salt spray up to approximately 500 hours per ASTM B117 salt-fog testing (typical aerospace requirement). In unmated state, the 806-022-MT14-7FTF female receptacle sockets are open and vulnerable to moisture ingress, dust, and corrosion. Designers must provide dust caps or mated counterparts during storage and non-operational periods, particularly in marine or coastal environments. The threaded coupling system of the 806-022-MT14-7FTF does not include integrated environmental seals, so users should specify optional neoprene or silicone coupling boots if the connector is subject to spray or high humidity.
How does the 806-022-MT14-7FTF's position count and form factor compare to miniature alternatives when space and weight constraints are critical?
The 806-022-MT14-7FTF is part of Glenair's Mighty Mouse 806 series with a 14-7 shell size, representing a mid-range circular connector footprint. A 7-position configuration on the 806-022-MT14-7FTF provides moderate density; equivalent functionality in a smaller form factor would require shell size 10 or 12 (such as Amphenol PT or Hirose HR series), which reduce position count to 4–5 positions or introduce higher contact density and tighter mating tolerances. The 806-022-MT14-7FTF's aluminum shell and panel-mount flange typically weigh 15–25 grams, compared to 5–8 grams for equivalent miniature 10-position connectors. In aerospace applications where weight targets are 5–10 pounds per 1000 feet of harness, replacing ten 806-022-MT14-7FTF connectors with miniature alternatives yields only 100–200 grams of savings—often insufficient to justify redesign costs and increased connector failure rates. The 806-022-MT14-7FTF is therefore preferred for systems where connector reliability and standard manufacturing processes outweigh marginal weight reductions.
What solder cup depth and wire-stripping requirements must be observed when assembling wires to the 806-022-MT14-7FTF?
The 806-022-MT14-7FTF's solder cup depth is typically 0.375–0.425 inches (9.5–10.8 mm), requiring wire stripping of 0.375 inches to achieve full cup fill without insulation encroachment into the solder joint. Under-stripped wire (insulation within 0.1 inches of the cup) creates a stress concentration where the insulation jacket and solder meet, reducing fatigue life during vibration or thermal cycling. Over-stripped wire (exceeding 0.5 inches) increases the length of unsupported conductor above the contact, raising susceptibility to mechanical pull-out or fracture. Best practice for the 806-022-MT14-7FTF involves using calibrated wire strippers and a solder pot temperature of 245–260°C (IPC J-STD-001 Pb-free) with dwell time of 3–5 seconds. The 806-022-MT14-7FTF's copper alloy contacts and aluminum housing require thermal management to prevent solder overflow into the connector cavity—a defect that bridges adjacent contacts and causes intermittent failures. Automated solder cup dipping with wave soldering equipment is recommended for production volumes above 500 units of the 806-022-MT14-7FTF.
Does the 806-022-MT14-7FTF meet MIL-DTL-38999 or AS22759 specifications, and how do commercial equivalents differ?
The 806-022-MT14-7FTF is a commercial circular connector that shares the general form factor of MIL-DTL-38999 (formerly MIL-C-38999) connectors but is not a direct specification replacement. The 806-022-MT14-7FTF does not carry MIL certification markings and may not meet all MIL-DTL-38999 requirements, such as insert temperature classification (Class C: 200°C, Class E: 150°C), contact resistance repeatability (50 mΩ maximum), or vibration resonance testing per MIL-STD-810. The 806-022-MT14-7FTF's nickel/PTFE shell finish is common in commercial aerospace but differs from the cadmium or nickel-PTFE composite specified in MIL-DTL-38999 shells. Wire gauge compatibility on the 806-022-MT14-7FTF may also differ; MIL-DTL-38999 specifies 20 AWG and 22 AWG solder cup sizes, whereas the 806-022-MT14-7FTF may support 18–20 AWG. For programs with explicit MIL-DTL-38999 requirements, sourcing genuine MIL-qualified connectors (such as Amphenol PT or Glenair MIL variants) is necessary; the commercial 806-022-MT14-7FTF may be acceptable for non-critical harnesses or as a cost-reduction alternative with customer approval and design verification testing.
What is the expected contact resistance behavior of the 806-022-MT14-7FTF after thermal aging at 200°C, and how does this affect signal integrity?
The 806-022-MT14-7FTF is rated to 200°C continuous operation, a specification that assumes the connector maintains contact resistance below 50 mΩ (typical aerospace requirement per MIL-DTL-38999) throughout the service life. However, sustained operation at 200°C causes the gold plating on the 806-022-MT14-7FTF contacts to undergo grain growth and potential diffusion into the copper substrate, typically increasing contact resistance by 10–20% after 1000 hours of thermal exposure. For high-frequency or signal integrity applications, this resistance increase translates to increased insertion loss: a 0.5 mΩ increase per contact on a 7-position 806-022-MT14-7FTF connector represents approximately 0.1–0.3 dB attenuation increase at microwave frequencies (X-band and above). The 806-022-MT14-7FTF is therefore suitable for moderate-bandwidth applications (DC to 100 MHz) but not recommended for millimeter-wave systems without impedance and loss budgeting validation. Designers requiring long-duration high-temperature operation above 150°C should specify periodic contact resistance measurement (in-service or during maintenance intervals) and establish a replacement threshold to prevent failure cascades.
How should the 806-022-MT14-7FTF be stored and handled prior to assembly to prevent solder wettability loss and contact degradation?
The 806-022-MT14-7FTF should be stored in a low-humidity environment (relative humidity ≤ 30%) at room temperature (18–25°C) to minimize moisture absorption in the polymer inserts and oxidation of exposed copper surfaces in the solder cups. Storage humidity above 60% for extended periods (greater than 3 months) may introduce moisture into the insert material, reducing dielectric strength and increasing the risk of leakage current between contacts during soldering. The gold-plated copper contacts on the 806-022-MT14-7FTF are resistant to tarnish, but the solder cup surfaces (if copper is exposed) are prone to oxidation over time. Pre-soldering flux application or cupric oxide formation on aged 806-022-MT14-7FTF solder cups requires extended dwell time (6–10 seconds at 245°C) to achieve adequate wetting, potentially degrading wire insulation adjacent to the contact. Best practice involves storing the 806-022-MT14-7FTF in sealed moisture-barrier bags with desiccant packets when shelf time exceeds 6 months. Handling the 806-022-MT14-7FTF with bare hands introduces skin oils and moisture; use gloves or finger cots to prevent contamination of the solder cups and contact surfaces. Once soldering is complete, the 806-022-MT14-7FTF assembly should be cleaned with IPA or equivalent flux-removal solvent to eliminate residual no-clean flux and reduce corrosion potential.
