M2T12SA5G13 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2T12SA5G13 is a toggle switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with a rated capacity of 0.4VA at 28V. This through-hole mounted component features a standard round actuator with a 12.70mm length and is designed for On-On switching applications. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. The part is RoHS3 compliant and REACH unaffected, with an electrical life rating of 50,000 cycles under process-sealed conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2T12SA5G13 are identified based on the following critical parameters that determine functional compatibility:

Electrical Parameters (Must Match or Exceed):

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: Substitute parts must support the application voltage requirement

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Actuator type: Standard Round
• Actuator length: 12.70mm
• Termination style: PC Pin

Environmental & Compliance Parameters:

• Operating temperature range: -30°C to 85°C
• RoHS3 compliance
• REACH unaffected status

The identified substitute parts (100AWSP1T1B4M2RE and 100AWSP1T1B4VS21RE) from E-Switch maintain identical mechanical configuration, circuit topology, and current rating. Both substitute parts are active products with enhanced ingress protection (IP67) and are RoHS3 compliant. The primary design consideration is the voltage rating differential: substitute parts are rated at 20V AC/DC, which is lower than the original 28V specification. This voltage derating must be evaluated against the actual application voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (100AWSP1T1B4M2RE and 100AWSP1T1B4VS21RE) are functionally equivalent to the M2T12SA5G13 for applications operating at 20V or below. The substitute parts offer the advantage of active product status with ongoing manufacturer support, ensuring long-term availability and supply chain stability compared to the obsolete NKK part.

Key considerations for selection:

Voltage Derating: The substitute parts are rated at 20V AC/DC versus the original 28V specification. Selection is appropriate only when the application voltage does not exceed 20V. If the circuit operates at voltages between 20V and 28V, the substitute parts are not suitable without circuit redesign.

Electrical Life: The original part specifies 50,000 cycles versus 30,000 cycles for the substitutes. Applications requiring extended cycle life should account for this 40% reduction in rated electrical life.

Ingress Protection Enhancement: Both substitute parts provide IP67 protection (dust tight, waterproof), which exceeds the original part's specification. This enhancement is beneficial for applications in harsh or moisture-prone environments.

Compliance Alignment: Both substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch parts directly replace the M2T12SA5G13 in all applications?

A: Direct replacement is limited by voltage rating. The E-Switch substitutes are rated at 20V AC/DC, while the original part is rated at 28V. Replacement is suitable only for applications operating at 20V or below. Applications requiring 28V operation require alternative solutions.

Q: What is the difference between 100AWSP1T1B4M2RE and 100AWSP1T1B4VS21RE?

A: Both parts are electrically and mechanically identical. The difference lies in packaging and actuator material designation within the part number structure. Both are available as active products from E-Switch with identical electrical specifications and performance characteristics.

Q: Does the reduced electrical life of the substitute parts affect compatibility?

A: The substitute parts are rated for 30,000 cycles versus 50,000 cycles for the original. This represents a 40% reduction in rated life. For applications with moderate switching frequency, this reduction may be acceptable. High-cycle applications should evaluate whether the reduced rating meets operational requirements.

Q: Are the substitute parts suitable for sealed or waterproof applications?

A: Yes. Both E-Switch substitutes provide IP67 ingress protection (dust tight, waterproof), which is superior to the original part's specification. This makes them suitable for sealed enclosures and moisture-exposed environments.

Q: What is the impact of the different actuator materials?

A: The original part features brass with nickel plating, while the substitutes use brass with chrome plating. Both materials provide corrosion resistance and durability suitable for standard industrial applications. Material selection does not affect electrical performance or mechanical compatibility.

Q: Are there any compliance or certification differences?

A: No. All three parts are RoHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across the original and substitute parts.
