1. BZ-2RW82276T Substitution Conclusion
The BZ-2RW82276T is a highly viable substitute for the GPTCRM01, as both share identical core electrical specifications (SPDT, 15A 125V AC, screw terminals) and actuator type (lever roller), with equivalent mechanical life. Key differences include the BZ-2RW82276T offering an additional DC rating of 125V DC at 500mA (not specified in the original part), slightly higher operating force (170gf vs. 158gf), shorter pretravel (2.0mm vs. 2.7mm), and reduced overtravel (1.27mm vs. 2.4mm). The substitute provides greater flexibility in DC applications, with a marginally stiffer tactile feel and slight differences in trigger point position and reset travel. Installation clearance and driving force compatibility should be verified, but overall interchangeability is excellent.
2. BZ-2RM22-A2 Substitution Conclusion
The BZ-2RM22-A2 requires careful evaluation as a substitute due to significant mechanical deviations from the original part. While electrical ratings (SPDT, 15A 125V AC, DC capability) and lifetime are identical, the actuator is changed to a lever straight-arm (non-roller), operating force increases substantially (538gf vs. 158gf), release force is higher (170gf vs. 43gf), and differential travel is minimal (0.025mm vs. 0.5mm). The substitute exhibits a noticeably stiffer actuation feel and a more "abrupt" trigger, demanding greater force and travel from the driving mechanism. It may not be suitable for applications relying on roller friction reduction or light-touch operation. Mechanical compatibility should be thoroughly validated.
