Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS4W03 is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount)
• Current and voltage ratings (6A AC at 125V; 4A DC at 30V)
• Actuator type and length (Standard Round, 10.50mm)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Bushing thread specification (M6 x 0.75)
• Operating temperature range (-30°C to 85°C)
• Electrical life (25,000 Cycles)

The substitute part MN12SS4W03 maintains compatibility with these core parameters, enabling direct functional replacement in applications currently utilizing the M2012SS4W03.
