1. 34BWDP31B1M1QT Substitution Conclusion Substitution is feasible with caution, contingent upon an evaluation of current derating and mechanical compatibility. This part is compatible with the original part's core circuit configuration (DPDT, On-Off-On) and mounting footprint (1/4-40 threaded bushing). Furthermore, its IP67 rating and epoxy-sealed terminals offer superior environmental robustness. Key deviations are its 5A current rating, which is slightly lower than the original's 6A, posing an overload risk in full-load or high inrush current applications. Additionally, the actuator differs from the original flat style, being a standard round type with a slightly shorter length (10.60mm vs. 11.38mm). This may affect panel aesthetic consistency and tactile feel. Provided the steady-state operating current remains below 5A and the panel cutout can be adapted, this part represents a reliable, upgraded alternative.
