Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2011SS4W01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Switch function (On-Off)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Actuator type and dimensions (Standard Round, 10.50mm length)
• Termination style (Solder Lug)
• Panel cutout and bushing specifications (Circular 6.50mm Dia, M6 x 0.75)
• Operating temperature range (-30°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part MN11SS4W01 is identified as an equivalent based on manufacturer designation and functional compatibility within the NKK Switches product family.

Parameter Comparison

Engineering Selection Recommendations

The M2011SS4W01 is classified as obsolete. The MN11SS4W01 is designated as an active product by NKK Switches and carries identical export classification (EAR99) and tariff codes (HTSUS 8536.50.9065), indicating functional and regulatory equivalence within the manufacturer's product portfolio.

Both parts comply with ROHS3 and REACH requirements. Selection between the main part and substitute should be based on availability and application requirements. The substitute part's active product status provides assurance of continued supply and manufacturing consistency.
