7203P3HZGE Replacement: 100DP3T1B1M1QEH, 100DP3T1B9M1QEH

Original Part

7203P3HZGE

Toggle Switch DPDT Panel Mount

Alternative Part

1. 100DP3T1B1M1QEH Substitution Conclusion Substitution is feasible, but there is one mechanical difference requiring evaluation. This part matches the original part (7203P3HZGE) completely in core electrical specifications (DPDT, On-Off-On, 5A/120V), mounting dimensions (6.35mm hole, 1/4-40 thread), and construction features (epoxy seal, solder lug terminals). The primary deviation lies in the actuator: the E-Switch part uses a standard round actuator with a slightly shorter length (10.41mm), whereas the C&K original part employs a flat anti-rotation actuator with a somewhat longer length (11.43mm). After substitution, the appearance and tactile feel of the actuator on the panel will differ (round vs. flat, with approximately 1mm less protrusion). Additionally, the anti-rotation feature of the original design—which prevents the toggle from turning under accidental torque—will be lost. Careful assessment is recommended for applications where strict prevention of actuator misalignment or consistent appearance is required. If such requirements are not critical, direct replacement is acceptable.

2. 100DP3T1B9M1QEH Substitution Conclusion Substitution is feasible, and the conclusion is identical to that for the 100DP3T1B1M1QEH above. Comparison shows that part 100DP3T1B9M1QEH and 100DP3T1B1M1QEH share identical published parameters, including actuator type, length, and material. The only distinction between them lies in E-Switch’s internal coding, which may correspond to lot variation, packaging method, or unspecified secondary attributes such as actuator color shade or minimum order quantity—with no documented technical specification differences. Its deviations from the original part, the resulting implications, and substitution feasibility are exactly the same as described in conclusion 1. That is, it likewise involves the shift from a “flat anti-rotation” to a “standard round” actuator, resulting in changes to appearance, tactile feel, and loss of the anti-rotation function.
