Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS1G03-BC is determined by strict equivalence across the following critical parameters:

  • Circuit configuration (SPDT)
  • Switch function (On-On)
  • Electrical ratings (0.4VA at 28V AC/DC)
  • Mounting interface (Panel Mount with 1/4-40 bushing thread)
  • Panel cutout dimensions (Circular 6.50mm Dia)
  • Termination style (PC Pin)
  • Actuator geometry (Standard round, 14.60mm length)
  • Operating temperature range (-30°C ~ 85°C)

The substitute part MN12SS1G03-BC meets these criteria and is classified as an active product, providing continuity for applications currently using the obsolete M2012SS1G03-BC.

Engineering Selection Recommendations

The MN12SS1G03-BC is the designated substitute for the obsolete M2012SS1G03-BC. Both parts are manufactured by NKK Switches and share identical electrical and mechanical specifications. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with export classification EAR99 and share the same HTSUS commodity code (8536.50.9065), indicating equivalent regulatory treatment. The main part is certified ROHS3 compliant and REACH unaffected; compliance documentation for the substitute should be verified through the manufacturer if required for your application.

Frequently Asked Questions (FAQ)

Q: Can MN12SS1G03-BC be used as a direct replacement for M2012SS1G03-BC?

A: Yes. Both parts are SPDT toggle switches with identical electrical ratings (0.4VA at 28V AC/DC), panel-mount configuration, PC pin termination, and mechanical dimensions. The substitute is the active product designation from NKK Switches.

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

A: The M2012SS1G03-BC is classified as obsolete, while MN12SS1G03-BC is the active equivalent. The electrical and mechanical specifications are identical. The part number change reflects the manufacturer's product line consolidation.

Q: Are there any packaging differences?

A: The main part is specified with packaging designation "-" while the substitute is supplied in Bulk packaging. Verify bulk packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: The M2012SS1G03-BC is certified ROHS3 compliant and REACH unaffected. Compliance documentation for MN12SS1G03-BC should be obtained from NKK Switches to confirm equivalent status for your regulatory requirements.

Q: What are the critical parameters for substitution?

A: Substitution is valid only when the replacement part maintains SPDT circuit configuration, On-On function, 0.4VA at 28V rating, panel-mount interface with 1/4-40 bushing, 6.50mm circular cutout, PC pin termination, and -30°C to 85°C operating range.

Q: Can I use this switch in applications beyond 28V?

A: No. The M2012SS1G03-BC and MN12SS1G03-BC are rated for 28V AC/DC maximum. Use in higher voltage applications exceeds component ratings and voids reliability.
