Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2011SS1W03-BA is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Current and Voltage Ratings: Substitute must support minimum 6A at 125V AC and 4A at 30V DC
• Mounting Interface: Panel mount configuration with circular 6.50mm diameter cutout and 1/4-40 bushing thread
• Termination: PC pin termination required for PCB integration
• Actuator Geometry: Standard round actuator with compatible cap design
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part MN11SS1W03-BA from NKK Switches meets these criteria as a direct equivalent within the manufacturer's product line.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical SPST circuit configuration, current ratings (6A AC / 4A DC), voltage ratings (125V AC / 30V DC), panel mount interface with 6.50mm circular cutout, 1/4-40 bushing thread, and PC pin termination. Mechanical and electrical compatibility is confirmed.

Q: What is the difference between these two part numbers?

A: The M2011SS1W03-BA is obsolete, while MN11SS1W03-BA is active production. The substitution reflects a product line update by NKK Switches while maintaining full electrical and mechanical compatibility.

Q: Are there any compliance differences between the main part and substitute?

A: No. Both parts are ROHS3 compliant, classified as EAR99, and share the same HTSUS code (8536.50.9065). Regulatory status is identical.

Q: What parameters must match for substitution to be valid?

A: Circuit configuration (SPST), current ratings (6A AC minimum / 4A DC minimum), voltage ratings (125V AC minimum / 30V DC minimum), panel mount interface dimensions, bushing thread specification (1/4-40), and PC pin termination are the critical parameters determining substitution validity.

Q: Is the actuator design identical between both parts?

A: Both parts feature a standard round actuator with cap. Mechanical compatibility with existing panel cutouts and operator interfaces is maintained.
