Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012SA2W13-BC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Current rating must meet or exceed 6A AC / 4A DC
• Voltage rating must meet or exceed 125V AC / 30V DC
• Operating temperature range must encompass -30°C to 85°C
• RoHS compliance status must be maintained

Substitute Parts Identified:

1. MN12SA2W13-BC (NKK Switches) — Manufacturer-recommended direct substitute. Active product status. Identical electrical and mechanical specifications to the main part.

2. 34ASP13B4V2QT (Grayhill Inc.) — Functionally equivalent alternative. Meets all primary compatibility criteria with equivalent or superior electrical ratings and operating characteristics.

Parameter Comparison

Engineering Selection Recommendations

MN12SA2W13-BC is the primary recommended substitute. As an active product from the original manufacturer NKK Switches, this part maintains design continuity and eliminates obsolescence risk. Selection of this substitute is appropriate for all applications currently using M2012SA2W13-BC.

34ASP13B4V2QT is a secondary alternative from Grayhill Inc. This part satisfies all primary compatibility criteria and maintains RoHS compliance. The DC current rating of 5A is lower than the original 4A specification, and the DC voltage rating of 28V is marginally lower than the original 30V specification. AC ratings remain equivalent at 125V and 5A. The extended electrical life rating of 40,000 cycles exceeds the original specification of 25,000 cycles. This substitute is suitable for applications where the specified DC parameters are not limiting factors.

Frequently Asked Questions (FAQ)

Q: Can MN12SA2W13-BC be used as a direct replacement for M2012SA2W13-BC?

A: Yes. MN12SA2W13-BC is the manufacturer-recommended substitute and maintains identical electrical and mechanical specifications. No circuit modifications are required.

Q: What are the key differences between 34ASP13B4V2QT and the original M2012SA2W13-BC?

A: The 34ASP13B4V2QT differs in the following parameters: DC current rating is 5A versus 4A, DC voltage rating is 28V versus 30V, and electrical life is 40,000 cycles versus 25,000 cycles. AC ratings remain equivalent. The part is manufactured by Grayhill Inc. rather than NKK Switches.

Q: Are both substitute parts RoHS compliant?

A: MN12SA2W13-BC compliance status is not specified in available documentation. 34ASP13B4V2QT is RoHS Compliant. The original M2012SA2W13-BC is ROHS3 Compliant.

Q: What is the significance of the obsolete status of M2012SA2W13-BC?

A: Obsolete status indicates the part is no longer manufactured or supported by NKK Switches. Substitution with an active product such as MN12SA2W13-BC or 34ASP13B4V2QT is necessary to ensure long-term component availability and supply chain continuity.

Q: Can 34ASP13B4V2QT be used in applications requiring 4A DC at 30V?

A: No. The 34ASP13B4V2QT is rated for 5A DC at 28V maximum. Applications requiring 4A DC at 30V exceed the specified DC voltage rating of this substitute and should use MN12SA2W13-BC instead.

Q: Are the through-hole mounting and PC pin termination identical across all three parts?

A: Yes. All three parts feature through-hole mounting and PC pin termination, ensuring mechanical and electrical compatibility at the board level.
