Substitute Part Grouping Explanation

Substitution eligibility for the M2029SS4G03 is determined by the following critical parameters:

Circuit configuration (DPDT)
Current and voltage ratings (0.4VA at 28V AC/DC)
Mounting type (Panel Mount)
Termination style (PC Pin)
Panel cutout dimensions (Circular - 6.50mm Dia)
Bushing thread specification (M6 x 0.75)
Operating temperature range (-30°C ~ 85°C)
Regulatory compliance (RoHS3, REACH Unaffected)

The substitute part MN29SS4G03 shares the same base product lineage (M2029SS series) and maintains compatibility across these critical parameters, enabling direct functional replacement in legacy applications.
