1. A221P32Y5ZQ Substitution Conclusion
The A221P32Y5ZQ is compatible with the original part in core electrical specifications (DPDT, On-Off-On actuation, voltage rating) and mounting dimensions (1/4-40 threaded bushing). Its higher current rating (6A) and longer electrical life (60,000 cycles) are performance advantages. However, its actuator is a flat-head type rather than the standard round knob, which alters the appearance and tactile feel. The most critical discrepancy is that its datasheet does not specify any IP rating. Consequently, it likely lacks the equivalent dust and water resistance of the original IP67-rated part. Therefore, this substitution is only suitable for general indoor applications where sealing is not required. It is not a direct replacement in applications demanding protection against dust, water splashing, or temporary immersion.
2. 2M1-DP3-T1-B1-M1QE Substitution Conclusion
The 2M1-DP3-T1-B1-M1QE is a near-perfect direct substitute for the original part. It maintains high consistency across all critical parameters, including circuit function, current/voltage ratings, IP67 environmental sealing, epoxy-sealed terminals, actuator type and material, and mounting dimensions. The only deviation is a minor 0.2mm difference in actuator length, which has no practical impact on mechanical installation or operation. This part provides fully equivalent electrical performance, environmental sealing, and mechanical compatibility, making it a drop-in replacement that requires no re-evaluation.
