Toggle Switch DPDT Panel Mount

Alternative Part

1. 100DP3T1B1M1QEH Substitution Conclusion From the perspectives of electrical performance and mechanical mounting interface, this part number can serve as a substitute for the original component, constituting a high-specification derated replacement. The core difference lies in its current and voltage ratings (5A 120V AC/28V DC), which are significantly higher than those of the original (0.4VA 20V). This provides greater electrical margin and safety headroom in the new application, enabling it to handle higher power loads. The primary difference to note is the actuator length (10.41mm), which is approximately 3.5mm shorter than the original (13.97mm). This results in a lower profile for the toggle lever above the panel, potentially affecting visual consistency and tactile feel during operation. However, it does not impact electrical connection or basic switching functionality. Mechanical mounting dimensions (panel cutout, thread) and terminal type are fully compatible.

2. 100DP3T1B9M1QEH Substitution Conclusion The substitution conclusion for this part number is identical to the previous one. According to E-Switch's part numbering convention, the distinction between "B1" and "B9" typically pertains only to cosmetic details of the actuator (toggle lever), such as color or finish (e.g., "B9" may indicate a black or other color variant). All critical electrical parameters (5A 120V AC/28V DC), mechanical dimensions (mounting hole diameter, thread, actuator length of 10.41mm), and characteristics (epoxy seal) are consistent with "100DP3T1B1M1QEH". Consequently, it shares the same performance advantages (higher specification) and form factor difference (shorter lever) relative to the original part. Its substitution feasibility is equivalent to the previous part. The final selection depends on specific panel appearance requirements (lever color).
