Alternative Part

1. GPTCRM01 Substitution Conclusion Direct substitution is not feasible. The key differences are as follows: The GPTCRM01 is rated for only 15 A AC (compared to the original model’s 20 A AC / 500 mA DC) and lacks DC voltage‑carrying capability, creating an overload risk in DC or AC loads exceeding 20 A. Its actuator is a lever‑roller type (versus the original direct‑acting plunger), resulting in a significantly lower operating force (158 gf vs. 624–850 gf) and different operating position and pre‑travel parameters. These changes may affect mounting compatibility and trigger characteristics. This substitute is suitable only for AC applications sensitive to operating force and with lower current requirements.

2. GPTCRM11 Substitution Conclusion Direct substitution is not recommended. The GPTCRM11 shares identical specifications with the GPTCRM01; therefore, its deviations from the original model are the same: reduced current rating to 15 A AC with no DC load support, a lever‑roller actuator in place of the direct‑acting plunger, substantially lower operating force, and notable differences in operating position and travel parameters. This variant can only be used in AC applications not exceeding 15 A, where mechanical interface and actuation characteristics can be accommodated. It cannot replace the original model in DC applications or where higher current ratings are required.
