1. 34ADP31B1M1QT Substitution Conclusion
This part can serve as a substitute, with one non-critical difference noted. It matches the original component exactly in all core electrical parameters (DPDT, On-Off-On, 5A current, 125V AC/28V DC ratings) and mechanical mounting dimensions (6.35mm panel hole, 1/4-40 thread). The electrical endurance is also identical, ensuring full functional and mechanical compatibility. The primary variations lie in the actuator type (standard round vs. original flat anti-rotation style) and a slightly shorter actuator length (10.41mm vs. 11.43mm). These affect only external feel and cosmetic alignment and do not compromise electrical safety. However, the substitute part lacks explicit specification for the "epoxy-sealed terminals" feature present in the original. In applications exposed to moisture, dust, or requiring flux resistance, this omission could impact long-term reliability. For typical clean, dry indoor environments, substitution is acceptable.
2. 34ADP31B1M1RT Substitution Conclusion
Direct substitution is not recommended due to a critical downgrade in electrical ratings. This part is rated for only 0.4VA (approximately 20mA at 20V AC/DC) and 20V, which is orders of magnitude below the original's 5A/120V AC power-handling capability. It is suitable solely for low-voltage, low-current signal switching applications. If used in the original 5A load circuit, contact overload, overheating, or failure will occur, creating a safety hazard. Although the mechanical dimensions and switching function are the same, the fundamental mismatch in electrical capacity disqualifies it as a power switch replacement. It may only be considered if the load conditions are confirmed to be within its minuscule ratings.
