M2011SS1W03 Equivalent & Substitute Parts

Part Overview

The M2011SS1W03 is a toggle switch manufactured by NKK Switches, configured as a single-pole single-throw (SPST) panel mount switch with on-off functionality. This component is rated for 6A at 125V AC and 4A at 30V DC, featuring a standard round actuator with non-illuminated design and PC pin termination. The product is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2011SS1W03 is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain SPST with on-off switching function. Current and voltage ratings must meet or exceed the original specifications: minimum 6A at 125V AC and 4A at 30V DC. Mounting type must be panel mount with compatible mechanical dimensions, including the 6.50mm circular panel cutout and 1/4-40 bushing thread. Termination style must be PC pin to ensure direct compatibility with existing PCB layouts. Operating temperature range must encompass the original -30°C to 85°C specification. Regulatory compliance, including RoHS3 and REACH status, must be maintained.

The identified substitute MN11SS1W03 from NKK Switches meets these criteria as an active product with equivalent electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MN11SS1W03 is the direct equivalent substitute for the obsolete M2011SS1W03. Both components are manufactured by NKK Switches and maintain identical electrical ratings and mechanical specifications. The substitute part is currently in active production status, ensuring availability for procurement and future supply chain continuity. Both parts maintain ROHS3 compliance and EAR99 export classification, supporting regulatory and compliance requirements. The transition from the obsolete M2011SS1W03 to the active MN11SS1W03 presents no functional or compatibility constraints for system integration.

Frequently Asked Questions (FAQ)

Q: Can the MN11SS1W03 be used as a direct replacement for the M2011SS1W03?
