Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2011LL1W01-A is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Current and Voltage Ratings: AC 6A at 125V and DC 4A at 30V must be met or exceeded
• Mounting Interface: Panel mount with 6.50mm circular cutout and 1/4-40 bushing thread
• Actuator Specification: Locking lever type with 16.50mm length
• Termination: Solder lug connection
• Environmental Compliance: RoHS3 compliance required

The MN11LL1W01-A is identified as a manufacturer-recommended substitute, maintaining the same electrical ratings, circuit configuration, and mechanical interface specifications while offering active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

The M2011LL1W01-A is obsolete; therefore, the MN11LL1W01-A is the manufacturer-recommended alternative for applications requiring SPST toggle switch functionality at 6A/125V AC or 4A/30V DC ratings. The substitute maintains the same circuit topology and panel-mount interface, ensuring mechanical and electrical compatibility in legacy system replacements and repairs.

The MN11LL1W01-A carries active product status, ensuring continued availability and supply chain reliability. Both components are manufactured by NKK Switches and comply with RoHS3 requirements, supporting environmental and regulatory compliance objectives.

Frequently Asked Questions (FAQ)

Q: Can the MN11LL1W01-A directly replace the M2011LL1W01-A in existing applications?

A: Yes. Both components share identical SPST circuit configuration, panel-mount mechanical interface (6.50mm cutout, 1/4-40 bushing thread), and equivalent electrical ratings. The substitute is the manufacturer-recommended replacement for the obsolete part.

Q: What are the critical parameters for SPST toggle switch substitution?

A: Circuit configuration (SPST), current ratings (6A AC / 4A DC minimum), voltage ratings (125V AC / 30V DC minimum), mounting type (panel mount), actuator type (locking lever), and termination style (solder lug) must all match or exceed the original specification.

Q: Why is the M2011LL1W01-A classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by NKK Switches. The MN11LL1W01-A provides functional equivalence with active product status and ongoing availability.

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

A: The M2011LL1W01-A packaging is unspecified in available data. The MN11LL1W01-A is supplied in bulk packaging. Confirm packaging requirements with your procurement or supply chain team for order fulfillment.

Q: Do both parts meet RoHS3 compliance?

A: The M2011LL1W01-A is confirmed RoHS3 compliant. RoHS3 compliance status for the MN11LL1W01-A is not specified in the provided substitute data; contact the manufacturer or authorized distributor for confirmation if regulatory compliance documentation is required.
