M2T12SA5W13 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2T12SA5W13 is a through-hole mounted toggle switch manufactured by NKK Switches, featuring Single Pole Double Throw (SPDT) configuration with On-On switching function. This component is rated for 6A at 125V AC and 4A at 30V DC, with a standard round actuator and PC pin termination. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2T12SA5W13 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
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C minimum

Electrical Compatibility Criteria:

• Current rating must support minimum 6A AC or equivalent
• Voltage rating must support minimum 125V AC or equivalent
• DC ratings must support minimum 4A at 30V or equivalent

Acceptable Variations:

• Actuator length within ±0.42mm (12.28mm to 12.70mm range)
• Electrical life rating of 25,000 cycles or greater
• Sealing method (Process Sealed, Epoxy Sealed Terminals)
• Actuator material composition (Brass with different plating options)

The following parts meet these substitution criteria: M2012SA2W13, 100AWSP1T1B4M2QE, 100AWSP1T1B4VS2QE, and 100AWSP1T1B4VS3QE.

Parameter Comparison

Engineering Selection Recommendations

M2012SA2W13 (NKK Switches): This substitute maintains identical electrical specifications to the M2T12SA5W13 with 6A AC and 4A DC ratings. Both components are obsolete products from the same manufacturer. The primary difference is actuator length (12.28mm versus 12.70mm), representing a 0.42mm reduction. This part is suitable for applications where the shorter actuator length is mechanically compatible with the panel cutout and user interface design. Packaging is supplied in trays.

100AWSP1T1B4M2QE, 100AWSP1T1B4VS2QE, 100AWSP1T1B4VS3QE (E-Switch): These three E-Switch alternatives are active products with enhanced specifications including IP67 ingress protection and extended electrical life (30,000 cycles versus 25,000 cycles). Current ratings are reduced to 5A AC/DC, and voltage ratings are 120V AC and 28V DC. These parts are suitable for applications where the lower current and voltage ratings are acceptable and where the enhanced environmental sealing and longer operational life provide system benefits. All three E-Switch variants are available in bulk packaging and represent current production alternatives to the obsolete NKK Switches original.

Compliance Status: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original M2T12SA5W13 specification.

Frequently Asked Questions (FAQ)

Q: Can the M2012SA2W13 be used as a direct replacement for the M2T12SA5W13?

A: The M2012SA2W13 is electrically equivalent with identical 6A AC and 4A DC ratings. The actuator length differs by 0.42mm (12.28mm versus 12.70mm). Mechanical compatibility depends on panel cutout dimensions and actuator engagement requirements in your specific application. Both parts are obsolete NKK Switches products.

Q: What are the key differences between NKK Switches and E-Switch alternatives?

A: The NKK Switches M2012SA2W13 maintains the original electrical specifications (6A AC, 4A DC). The E-Switch 100A series alternatives (100AWSP1T1B4M2QE, 100AWSP1T1B4VS2QE, 100AWSP1T1B4VS3QE) provide reduced current ratings (5A AC/DC) but offer IP67 environmental protection and extended electrical life (30,000 cycles). E-Switch parts are active products with current manufacturing availability.

Q: Are the three E-Switch part numbers interchangeable?

A: Yes. The 100AWSP1T1B4M2QE, 100AWSP1T1B4VS2QE, and 100AWSP1T1B4VS3QE share identical electrical and mechanical specifications. All three are SPDT On-On toggle switches with 5A AC/DC ratings, 120V AC, 28V DC, 12.70mm actuators, and IP67 protection. Selection between these variants depends on packaging requirements and inventory availability.

Q: What is the impact of reduced current rating on system design?

A: The E-Switch alternatives are rated for 5A AC/DC compared to the original 6A AC and 4A DC. Applications operating at or below 5A AC and 5A DC are fully compatible. Applications requiring the full 6A AC specification must use the M2012SA2W13 or original M2T12SA5W13. Voltage ratings (120V AC, 28V DC for E-Switch versus 125V AC, 30V DC for NKK) are similarly reduced but remain suitable for standard industrial control applications.

Q: Does IP67 protection affect mechanical installation?

A: IP67 ingress protection on the E-Switch alternatives indicates dust-tight and waterproof sealing. This does not affect through-hole mounting or PC pin termination compatibility. Installation procedures remain identical to the original M2T12SA5W13. The enhanced sealing provides additional environmental protection in applications exposed to moisture or particulate contamination.

Q: What packaging options are available?

A: M2T12SA5W13 original specification does not define packaging. M2012SA2W13 is supplied in trays. E-Switch alternatives (100AWSP1T1B4M2QE, 100AWSP1T1B4VS2QE, 100AWSP1T1B4VS3QE) are supplied in bulk packaging. Packaging selection should align with procurement and assembly requirements.
