1. 7203P3YZGE Substitution Conclusion A detailed comparison confirms that the 7203P3YZGE is a fully acceptable substitute for the original part number 100DP3T6B11M1QEH in terms of electrical performance, mounting dimensions, and core functionality. Both switches are DPDT with On-Off-On actuation, rated for 5A (AC/DC), 120V AC, and 28V DC. They share identical mounting hardware, utilizing a 1/4-40 bushing and a 6.35mm panel cutout. The terminal type is solder lug with epoxy sealing, and the actuator material is the same. The sole technical deviation is the actuator (bat handle) length: the original measures 12.29mm, while the substitute is 11.43mm, a difference of 0.86mm. Consequently, the substitute's bat handle will be approximately 0.86mm shorter. This represents only a minor visual and tactile variation. It does not impact the switch's electrical characteristics, installation, or fundamental operational function. Therefore, the 7203P3YZGE can be considered a direct, functionally equivalent replacement in the vast majority of applications.
