V8DADHHC-EHH00-000 Substitution Analysis and Conclusion A comprehensive comparative analysis confirms that the V8DADHHC-EHH00-000 is a fully qualified drop-in replacement for the original part number V8D1DHHC-BHC00-000. Both models are identical in all critical aspects: core electrical parameters (SPDT circuit, Momentary-Off-Momentary function, 20A @ 12VDC rating), mechanical specifications (panel cutout dimensions, quick-connect terminals, IP66/IP68 ingress protection rating), and operational life specifications. This ensures full functional, performance, and installation compatibility. The sole and key distinction lies in the actuator (button) color: the original model features a black actuator, while the substitute model uses a gray one. This variation is purely cosmetic and does not entail any change in electrical or mechanical performance. However, implementing this substitution will result in the switch's visible actuator color on the device panel changing from black to gray. Provided that this color change does not conflict with the final product's aesthetic coordination or violate any specific customer requirements, this substitution is technically sound and fully viable.
