M2012S2A2G13 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2012S2A2G13 is a toggle switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-On functionality. This through-hole mounted component is rated for 0.4VA at 28V AC/DC operation. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012S2A2G13 is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must support 0.4VA or higher
• Voltage rating must support minimum 28V AC/DC
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Actuator length must be 6.86mm
• Operating temperature range must encompass -30°C to 85°C

Substitute parts are grouped into two categories: the manufacturer-recommended upgrade (MN12S2A2G13 from NKK Switches) and similar alternatives from C&K and Electroswitch that meet the electrical and mechanical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

The MN12S2A2G13 from NKK Switches is the manufacturer-recommended upgrade path for the obsolete M2012S2A2G13. This part maintains the same manufacturer lineage and is currently in active production status with ROHS3 compliance.

For applications requiring exact voltage matching at 28V AC/DC, the A123M1D9V30B from Electroswitch provides full compatibility with identical voltage ratings, higher current capacity (0.5VA), and active product status. This part operates across an extended temperature range (-30°C to 90°C) and maintains RoHS compliance.

The C&K 7000 series alternatives (7101MD9V31BE, 7101MD9V3BE, 7101MD9V4BE, 7101MD9V9BE, and 7101MPD9V3BE) are electrically compatible for applications where 20V operation is acceptable. These parts feature extended electrical life (100,000 cycles versus 50,000 cycles in the original), active product status, and ROHS3 compliance. The 7101MPD9V3BE variant includes anti-rotation actuator design for applications requiring enhanced mechanical stability.

The E101MD9V9BE from C&K offers IP57 ingress protection for applications requiring dust and water resistance, though it operates at reduced electrical life (40,000 cycles) and lower voltage rating (20V).

Frequently Asked Questions (FAQ)

Q: Can C&K 7000 series parts rated at 20V substitute for the M2012S2A2G13 rated at 28V?

A: C&K 7000 series parts are electrically compatible for SPDT On-On switching function and current capacity. However, they are rated for 20V maximum, which is below the original 28V specification. Substitution is valid only for applications operating at 20V or lower. Applications requiring full 28V operation must use MN12S2A2G13 or A123M1D9V30B.

Q: What is the difference between 7101MD9V3BE and 7101MPD9V3BE?

A: Both parts are C&K 7000 series SPDT switches with identical electrical ratings and operating parameters. The primary difference is actuator type: 7101MD9V3BE features a standard round actuator, while 7101MPD9V3BE includes an anti-rotation actuator design. The 7101MPD9V3BE is specified for applications where accidental actuator rotation must be prevented.

Q: Does packaging type affect electrical compatibility?

A: No. Packaging differences (Bulk versus Tray) do not affect electrical or mechanical compatibility. Packaging selection is determined by procurement and assembly process requirements only.

Q: Why does the A123M1D9V30B have higher current rating (0.5VA) than the original part (0.4VA)?

A: The A123M1D9V30B is rated for 0.5VA, which exceeds the original 0.4VA specification. This higher rating indicates the part can safely handle the original current requirement with additional capacity margin. The part is fully compatible for applications designed for 0.4VA operation.

Q: Is the E101MD9V9BE suitable for general replacement?

A: The E101MD9V9BE is suitable only for applications requiring IP57 ingress protection (dust and water resistance). It operates at 20V maximum and provides reduced electrical life (40,000 cycles). For standard applications without environmental protection requirements, other alternatives are preferred.

Q: What compliance certifications are maintained across substitute parts?

A: All substitute parts maintain ROHS3 compliance or equivalent RoHS compliance. The original M2012S2A2G13 and all recommended substitutes are ECCN EAR99 classified and share the same HTSUS code (8536.50.9065), ensuring regulatory consistency for procurement and export documentation.
