1. 100DP3T1B1M1QEH Substitution Conclusion
Substitution is generally feasible, but the application environment must be evaluated. This part is a direct pin-compatible replacement, with full alignment to the original part in core specifications: circuit function, current/DC voltage ratings, mounting dimensions (hole diameter, thread), and contact sealing. The primary differences are a slightly lower AC voltage rating (120V vs. 125V, typically acceptable in practice) and the lack of a specified IP rating. Direct substitution may pose a risk in harsh environments requiring IP67 protection against water and dust (e.g., outdoor or washdown applications). Furthermore, its electrical endurance (40,000 cycles) is moderately lower than the original's (50,000 cycles), which should be considered for ultra-high frequency switching applications.
2. M2023SD3W01 Substitution Conclusion
Conditional substitution; electrical and mechanical compatibility require strict assessment. This part offers identical circuit functionality and a higher AC current rating (6A). However, its lower DC current rating (3A vs. 5A) presents a key limitation, posing a potential overload risk for DC loads, especially those near 28V. Additionally, its required panel cutout diameter is slightly larger (6.50mm vs. 6.35mm). Direct replacement could result in a loose fit or necessitate panel modification. The significantly lower electrical endurance (25,000 cycles) also renders it less reliable in applications demanding high durability. While its IP67 rating is a distinct advantage, the aforementioned discrepancies preclude it from being a direct drop-in replacement. It may only be considered for applications where the DC load current is under 3A, panel modification is acceptable, or longevity requirements are not critical.
