Frequently Asked Questions(FAQ)

What is the operating temperature range and reset behavior of the Sensata-Airpax 67L115-0377 thermostat in a TO-220-2 package?
The 67L115-0377 is a fixed-temperature thermostat with a switching point at 240°F (115°C) and a reset temperature of 176°F (80°C). This means it closes its SPST-NC contacts when the ambient temperature exceeds 115°C and opens them again once the temperature drops to 80°C. The hysteresis between switch and reset points is approximately 35°C, which helps prevent rapid cycling near the threshold. These characteristics make it suitable for thermal protection applications where a simple on/off response is required without external control circuitry.
How does the current rating and voltage capability of the 67L115-0377 compare to similar thermostats in the 6700 series?
The 67L115-0377 supports up to 0.5A at 48V DC, which is typical for low-power switching thermostats. Compared to other members of the 6700 series, such as those rated for 110°C or 125°C thresholds, this model generally offers lower current handling due to its compact TO-220-2 packaging and design optimization for signal-level or moderate power loads. Higher-rated versions may support slightly higher currents but often at reduced voltage limits due to contact erosion considerations. For designs requiring greater than 0.5A continuous current, alternative thermal protection solutions with external relay interfaces are typically recommended.
What mounting configuration and termination options are available for the 67L115-0377, and how do they affect PCB integration?
The 67L115-0377 uses a TO-220-2 package with PC pins, enabling through-hole mounting directly onto printed circuit boards. This configuration provides mechanical stability and facilitates soldering in high-reliability applications. The dual-pin design simplifies layout by allowing direct connection to load circuits without additional interfacing hardware. However, designers must ensure adequate clearance and thermal management near heat sources, as the plastic body has limited thermal resistance compared to metal-can alternatives.
What is the expected lifespan and reliability specification for the 67L115-0377 based on switching cycles?
The 67L115-0377 is rated for 20,000 switching cycles under normal operating conditions. This endurance level reflects the durability of its bimetallic sensing element and contact mechanism. While sufficient for most consumer and industrial control systems, applications involving frequent thermal cycling beyond this rating should consider redundant protection or solid-state alternatives. The actual service life can vary depending on environmental factors such as humidity, vibration, and contact arcing during switching events.
Can the 67L115-0377 be used in automotive or high-vibration environments, and what precautions apply?
Although the 67L115-0377 is not specifically qualified for automotive standards like AEC-Q200, its rugged TO-220-2 construction allows use in moderately demanding environments. In high-vibration settings, secure PCB mounting and strain relief on leads are essential to prevent fatigue failure. Additionally, the ±9°F tolerance implies some variability in trip point accuracy, so calibration testing under actual operating conditions is advisable if precise thermal thresholds are critical. For safety-critical automotive systems, formal qualification per relevant standards is strongly recommended.
How does the tolerance of ±9°F (±5°C) impact system design when using the 67L115-0377?
The ±5°C tolerance indicates inherent variation in the thermostat’s activation temperature due to manufacturing variances in the bimetallic strip. This means that in a batch of units, the actual switching point may fall anywhere between 110°C and 120°C. Designers must account for this margin by selecting application-specific safety margins—typically increasing the nominal threshold by 5–10% to ensure reliable operation within acceptable limits. This tolerance also affects calibration procedures in precision thermal control systems.
Is the 67L115-0377 RoHS compliant, and what implications does this have for international regulatory compliance?
Yes, the 67L115-0377 is RoHS compliant, meaning it meets European Union restrictions on hazardous substances including lead, mercury, cadmium, and certain brominated flame retardants. This status facilitates global distribution, particularly in markets requiring full REACH and RoHS alignment. The device’s MSL rating of 1 confirms it poses no moisture-related assembly risks, simplifying production planning across regions with varying climate controls.
What are the key differences between the 67L115-0377 and higher-temperature variants like the 67L125-0377 in terms of thermal performance and application suitability?
The 67L125-0377 switches at 257°F (125°C), compared to the 67L115-0377’s 240°F (115°C), making it more appropriate for hotter environments such as motor windings or power supply heatsinks. Both share the same TO-220-2 package, current rating, and reset hysteresis behavior, but the higher-trip variant may exhibit slightly different contact wear characteristics due to increased arc energy during switching. Selection depends on whether the protected component operates closer to 115°C or requires protection above that threshold, with derating considerations applied in both cases.
