Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS1G03-BE is determined by strict equivalence across the following critical parameters:

Circuit configuration (SPDT)
Switch function (On-On)
Electrical ratings (0.4VA at 28V AC/DC)
Mounting interface (Panel Mount with 1/4-40 bushing thread and 6.50mm circular cutout)
Termination style (PC Pin)
Actuator geometry (Standard round with 14.60mm length)
Operating temperature range (-30°C to 85°C)
Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The MN12SS1G03-BE meets these substitution criteria as a functionally equivalent alternative from the same manufacturer.
