1.34BWDP32B1M1RT Substitution Conclusion Direct substitution is not recommended. The Grayhill 34BWDP32B1M1RT matches the original part only in mechanical interface (e.g., mounting threads, termination style) and basic function (DPDT On-Off-On). However, critical electrical parameters and physical dimensions differ significantly. First, there is a substantial gap in electrical load capability. The original part is rated for 6A 125V AC / 28V DC, whereas the substitute is only rated for 0.4VA (approximately 20mA @ 20V) with a maximum voltage of 20V AC/DC. The substitute cannot handle the power or current levels of the original design. Direct replacement could lead to switch overload, failure, or a safety hazard. Second, the actuator length is shorter (5.50mm vs. 10.41mm), which may affect panel operation feel or mechanical compatibility. Although the substitute offers a higher ingress protection rating (IP67 vs. splash-proof sealing) and a slightly lower electrical endurance (50,000 cycles vs. 60,000 cycles), the severe downgrade in electrical specifications is the decisive limiting factor. Therefore, this substitute is only suitable for specific, very low-power applications where voltage does not exceed 20V. It cannot meet the general power-handling requirements of the original part.
