M2012SA2W13-BA Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2012SA2W13-BA is a through-hole mounted toggle switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The switch is rated for 6A AC at 125V and 4A DC at 30V, with a standard round actuator featuring a black cap and non-illuminated design.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Through Hole
• Termination style: PC Pin
• Current rating: Minimum 5A AC (original rated 6A AC)
• Voltage rating: Minimum 125V AC (original rated 125V AC)
• Operating temperature range: -30°C to 85°C or broader
• Non-illuminated design

Substitute Classification:

MFR Recommended Substitute: MN12SA2W13-BA (NKK Switches) — Direct manufacturer equivalent with identical electrical specifications and active product status.

Similar Substitute: 34ASP13B4V2QT (Grayhill Inc.) — Functionally equivalent SPDT toggle switch meeting all primary compatibility criteria with active product status and enhanced electrical life rating.

Parameter Comparison

Engineering Selection Recommendations

MN12SA2W13-BA is the primary substitute option. As an active product from the original manufacturer (NKK Switches), this part maintains design continuity and eliminates obsolescence risk. Selection of this substitute is supported by manufacturer recommendation and active product status.

34ASP13B4V2QT is a secondary substitute option. This Grayhill Inc. component meets all primary electrical and mechanical compatibility criteria with active product status. The 34ASP13B4V2QT provides enhanced electrical life (40,000 cycles versus 25,000 cycles) and maintains RoHS compliance. DC voltage rating is 28V versus the original 30V; this represents a minor reduction in DC voltage margin and must be evaluated against specific application requirements.

Both substitutes carry active product status and current compliance certifications (RoHS, REACH Unaffected, EAR99), eliminating long-term procurement and regulatory risk associated with the obsolete original part.

Frequently Asked Questions (FAQ)

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

A: Yes. MN12SA2W13-BA is the manufacturer-recommended substitute from NKK Switches and carries active product status. Both parts share identical circuit configuration (SPDT), switch function (On-On), and mounting specifications (Through Hole, PC Pin termination).

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

A: The 34ASP13B4V2QT is manufactured by Grayhill Inc. rather than NKK Switches. Electrical specifications are equivalent for AC operation (125V, 5A versus 6A). DC voltage rating is 28V versus 30V. Electrical life is extended to 40,000 cycles. All other parameters including circuit configuration, switch function, mounting type, and operating temperature range are identical.

Q: Are there packaging differences between these substitutes?

A: MN12SA2W13-BA is supplied in Bulk packaging. Original packaging information for M2012SA2W13-BA is not specified. 34ASP13B4V2QT packaging is not specified. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do all substitutes meet RoHS compliance?

A: M2012SA2W13-BA is ROHS3 Compliant. MN12SA2W13-BA compliance status is not specified. 34ASP13B4V2QT is RoHS Compliant. Both substitutes carry REACH Unaffected and EAR99 classifications matching the original part.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements and supply chain preferences. MN12SA2W13-BA maintains design continuity with the original manufacturer. 34ASP13B4V2QT offers extended electrical life and alternative sourcing. Both are active products with current compliance certifications.
