Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2011SS1W01/CUL is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

The substitute part M2011SS1W01/CUL-N983 maintains functional and mechanical equivalence within the NKK Switches M-series product line, ensuring direct interchangeability in existing circuit designs and panel assemblies.
