1. GPTCRM01 Substitution Conclusion Substitution is feasible, but requires careful evaluation of mechanical compatibility and environmental sealing requirements. The GPTCRM01 offers a significantly higher current rating (15A) compared to the original part (1A), providing greater electrical margin. However, critical differences exist in the actuator type (lever roller vs. round pin plunger), operating force (158gf vs. 368~538gf), and travel parameters (e.g., differential travel of 0.5mm vs. 0.05mm). These variances may lead to incompatibility with existing mounting holes or trigger mechanisms, and will likely alter the tactile feel of actuation. Furthermore, while the original component is rated IP64, the GPTCRM01 datasheet does not specify an ingress protection rating. Direct substitution is not recommended for applications exposed to dust or moisture. Although the mechanical life is identical (20 million cycles), the electrical endurance is unspecified and must be validated under the actual load conditions.

2. GPTCRM11 Substitution Conclusion The conclusion for the GPTCRM11 is identical to that for the GPTCRM01. As the GPTCRM11 shares all specifications with the GPTCRM01, its substitution feasibility is the same: improved electrical performance but potential concerns regarding mechanical and environmental compatibility. Both substitute models feature a lever roller actuator, lower operating force, and larger travel parameters. Compared to the original model's compact differential travel (0.05mm) and pin plunger design, these changes could affect precision positioning or response accuracy. Similarly, the absence of a stated IP rating makes them unsuitable for direct replacement if the original design relies on IP64 protection. Substitution may be considered in applications where mechanical fit is confirmed, environmental conditions permit, and higher current capacity is needed, but functional reliability must be verified through physical testing.
