2. Substitution Conclusion for 100DP3T6B11M1QE This component is essentially a direct substitute, though mechanical compatibility should be verified. Its electrical specifications (5A/120V AC/28V DC), switching function (DPDT On-Off-On), and key characteristics (epoxy-sealed terminals, 40,000-cycle life) are fully aligned with the original part. The only notable difference is a slightly longer actuator length (12.29mm vs. 11.43mm). In applications with tight panel thickness or internal space constraints, this may require checking for potential interference or operational feel. However, both electrical performance and mounting dimensions (panel cutout, thread size) remain compatible.
