Substitute Part Grouping Explanation

Substitution of the M2012B2B3W01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 17.50mm)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular 12.50mm Dia)
• Bushing thread specification (M12 x 1)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (25,000 Cycles minimum)
• Regulatory compliance (ROHS3 Compliant)

The substitute part MN12B2B3W01 is identified as the manufacturer-recommended equivalent based on these parameters.

Parameter Comparison
