1. GPTCRM01 Substitution Conclusion The GPTCRM01 is fully compatible with the original model BZ-2RW82276T in terms of key electrical specifications (SPDT, 15A 125V AC, snap-action mechanism, screw terminals) and mechanical life (20 million operations), providing a solid basis for direct substitution. The differences are as follows: First, the GPTCRM01 does not specify a DC rating (the original model is rated for 500mA 125V DC), requiring risk assessment if the application involves DC loads. Second, minor deviations exist in mechanical travel parameters (operating position is 0.4mm shorter, while pretravel and overtravel are increased by 0.7mm and 1.13mm, respectively). This necessitates verification of actuator compatibility, though it generally does not affect standard linkage applications. Third, the operating force is reduced by 12gf (158gf vs 170gf), indicating lighter actuation but potentially slightly different sensitivity to vibration. In summary, substitution is acceptable for pure AC loads provided mechanical mounting is compatible; however, applications involving DC loads or precise mechanical linkage require physical validation.
