1. 7203SYCQE Substitution Conclusion After comparison, the C&K 7203SYCQE shows a high degree of alignment with the E-Switch 100DP3T1B1M2QEH in core electrical parameters, mounting dimensions, and mechanical characteristics. This includes identical DPDT circuitry, On-Off-On functionality, a 5A/120V rating, 1/4-40 threaded bushing, and epoxy-sealed terminals, confirming its suitability as a direct replacement. The sole discrepancy lies in the actuator length: the 7203CQE measures 10.67mm, while the original part is 10.41mm, resulting in a 0.26mm difference. Substitution will therefore cause the switch knob to protrude approximately 0.26mm further from the panel surface. This may slightly affect visual flushness or clearance with adjacent components, but typically does not compromise electrical performance or mechanical compatibility. Provided the application does not impose strict constraints on actuator projection, this part can be considered an equivalent substitute.
