NKK Switches M2011SD3W01 Equivalent & Substitute Parts

Part Overview

The M2011SD3W01 is a toggle switch manufactured by NKK Switches, classified as SPST (Single Pole Single Throw) with On-Off functionality. This panel-mount switch is rated for 6A at 125V AC and 4A at 30V DC, featuring a non-illuminated standard round actuator with solder lug termination. The product is currently obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The MN11SD3W01 qualifies as a direct substitute for the M2011SD3W01 based on the following critical parameters:

• Electrical Specifications: Both parts maintain identical current ratings (6A AC / 4A DC) and voltage ratings (125V AC / 30V DC)
• Circuit Configuration: Both are SPST On-Off switches
• Mechanical Interface: Identical panel cutout dimensions (6.50mm circular) and bushing thread (1/4-40) ensure mechanical compatibility
• Termination: Both use solder lug termination
• Environmental Protection: Both meet IP67 ingress protection requirements
• Compliance: Both are ROHS3 compliant

The primary difference is product status: M2011SD3W01 is obsolete while MN11SD3W01 is active, with MN11SD3W01 featuring a longer actuator (13.10mm vs 10.50mm) and actuator cap design.

Parameter Comparison

Engineering Selection Recommendations

The MN11SD3W01 is the recommended substitute for the obsolete M2011SD3W01. Both parts maintain identical electrical and mechanical specifications critical to circuit functionality. The MN11SD3W01 is currently in active production with substantial inventory availability (35,497 units), ensuring supply chain continuity.

The actuator length difference (13.10mm vs 10.50mm) and actuator cap design on the MN11SD3W01 represent physical modifications that do not affect electrical performance or panel mounting compatibility, as the panel cutout dimensions and bushing thread specifications remain unchanged. Both parts satisfy ROHS3 compliance requirements and IP67 environmental protection standards.

Frequently Asked Questions (FAQ)

Q: Can MN11SD3W01 directly replace M2011SD3W01 in existing applications?

A: Yes. The electrical ratings, circuit configuration, and mechanical interface specifications are identical. The panel cutout diameter and bushing thread remain unchanged, ensuring direct mechanical compatibility.

Q: What is the significance of the actuator length difference?

A: The MN11SD3W01 features a 13.10mm actuator compared to the M2011SD3W01's 10.50mm actuator. This difference affects the physical reach of the toggle mechanism but does not impact electrical performance or panel mounting compatibility. Panel clearance must be verified for the specific enclosure design.

Q: Are both parts RoHS compliant?

A: Yes. Both M2011SD3W01 and MN11SD3W01 are ROHS3 compliant.

Q: What is the difference between the actuator designs?

A: The M2011SD3W01 uses a standard round actuator, while the MN11SD3W01 uses a standard round actuator with a cap. This is a cosmetic and ergonomic difference that does not affect electrical specifications.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 6A at 125V AC and 4A at 30V DC, with identical SPST On-Off functionality.

Q: What ingress protection rating do these switches provide?

A: Both parts meet IP67 specifications, providing dust-tight and waterproof protection.
