M2011SD3W01-BA Toggle Switch SPST Equivalent & Substitute Parts

Part Overview

The M2011SD3W01-BA is a panel-mount toggle switch manufactured by NKK Switches, configured as a single-pole single-throw (SPST) on-off switch rated for 6A at 125V AC and 4A at 30V DC. This component features a non-illuminated standard round actuator with solder lug termination and IP67 ingress protection. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2011SD3W01-BA is determined by the following critical parameters:

• Circuit configuration (SPST)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Ingress protection rating (IP67 or equivalent)
• Operating temperature range (-30°C to 85°C or broader)

The substitute part MN11SD3W01-BA is classified as a manufacturer-recommended equivalent and maintains compatibility across these critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MN11SD3W01-BA is designated as the manufacturer-recommended substitute for the obsolete M2011SD3W01-BA. Both components are manufactured by NKK Switches and share identical ECCN and HTSUS classifications, confirming regulatory alignment. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Current inventory levels for the substitute (1107 pieces) support immediate procurement requirements.

Selection of the MN11SD3W01-BA is appropriate for applications requiring SPST toggle switch functionality with panel-mount configuration and solder lug termination. Verification of electrical ratings and mechanical fit within the specific application is necessary prior to implementation, as complete parameter specifications for the substitute part are not fully detailed in the available data.

Frequently Asked Questions (FAQ)

Q: Why is the M2011SD3W01-BA classified as obsolete? A: The M2011SD3W01-BA has reached end-of-life status with NKK Switches. The manufacturer-recommended substitute MN11SD3W01-BA provides functional equivalence for ongoing applications.

Q: What are the critical parameters for substitution compatibility? A: Substitutes must maintain SPST circuit configuration, minimum 6A/125V AC and 4A/30V DC ratings, panel-mount installation, solder lug termination, 6.50mm circular panel cutout, IP67 ingress protection, and -30°C to 85°C operating temperature range.

Q: Is the MN11SD3W01-BA a direct replacement? A: The MN11SD3W01-BA is the manufacturer-designated equivalent. Both components are NKK Switches products with identical ECCN and HTSUS classifications. Complete electrical and mechanical specifications should be cross-referenced with the manufacturer's current datasheets to confirm full compatibility for your specific application.

Q: What is the difference in packaging between the main part and substitute? A: The M2011SD3W01-BA is supplied with standard packaging, while the MN11SD3W01-BA is available in bulk packaging. This distinction affects procurement quantities and handling procedures but does not impact functional performance.

Q: Are both parts RoHS compliant? A: The M2011SD3W01-BA is confirmed ROHS3 compliant. RoHS compliance status for the MN11SD3W01-BA is not specified in the available data and should be verified with the manufacturer if regulatory compliance is a requirement for your application.
