Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012B2B3W01-VC is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular 12.50mm Dia)
• Bushing thread specification (M12 x 1)
• Termination style (Solder Lug)
• Ingress protection rating (IP67 minimum)
• Operating temperature range (-30°C to 85°C minimum)

The MN12B2B3W01-VC qualifies as a manufacturer-recommended substitute based on alignment with these core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MN12B2B3W01-VC is the manufacturer-recommended substitute for the obsolete M2012B2B3W01-VC. Both components maintain identical electrical specifications, mechanical dimensions, and termination characteristics. The primary distinction is product status: the M2012B2B3W01-VC is obsolete, while the MN12B2B3W01-VC is active and currently in production.

Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, ensuring regulatory and trade compliance equivalence. The active status of the MN12B2B3W01-VC provides supply continuity and long-term availability assurance for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MN12B2B3W01-VC directly replace the M2012B2B3W01-VC in existing applications?

A: Yes. Both components share identical electrical ratings (6A/125V AC, 4A/30V DC), circuit configuration (SPDT), mechanical dimensions, panel cutout specifications (12.50mm circular), bushing thread (M12 x 1), and termination style (Solder Lug). No circuit modifications or mechanical redesign is required.

Q: What is the primary reason for substitution?

A: The M2012B2B3W01-VC is classified as obsolete. The MN12B2B3W01-VC is the active equivalent, ensuring continued supply availability and long-term component sourcing for maintenance and production.

Q: Are there packaging differences between these parts?

A: The M2012B2B3W01-VC is supplied in standard packaging, while the MN12B2B3W01-VC is supplied in bulk packaging. Both maintain identical component specifications and performance characteristics.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the M2012B2B3W01-VC and MN12B2B3W01-VC are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring equivalent regulatory and trade compliance.

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify that the replacement component maintains SPDT circuit configuration, On-On switch function, 6A/125V AC and 4A/30V DC ratings, panel-mount configuration with M12 x 1 bushing thread, 12.50mm circular panel cutout, solder lug termination, and IP67 ingress protection.
