M2015ES1W01 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2015ES1W01 is a panel-mount toggle switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration. This component operates at 6A AC / 3A DC with 125V AC / 30V DC ratings and features a flatted brass actuator with epoxy-sealed solder lug terminals. The part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from primary sources.

Substitution eligibility for the M2015ES1W01 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Bushing thread must be 1/4-40
• Actuator material must be Brass, Chrome Plated

Electrical Performance Criteria:

• AC current rating must be equal to or greater than 6A
• DC current rating must be equal to or greater than 3A
• AC voltage rating must be equal to or greater than 125V
• DC voltage rating must be equal to or greater than 30V

Environmental & Mechanical Criteria:

• Operating temperature range must encompass -30°C to 85°C

Four substitute parts meet these criteria with varying degrees of parameter alignment and product status advantages.

Parameter Comparison

Engineering Selection Recommendations

A126P31YZQ (Electroswitch) - Preferred Substitute

This part provides the closest electrical and mechanical alignment to the M2015ES1W01. It matches the 6A AC current rating and 125V AC voltage specification exactly. The flatted actuator type, actuator length of 11.38mm, and operating temperature range of -30°C to 90°C provide superior compatibility. The part is currently active in production with RoHS compliance certification. Electrical life of 60,000 cycles exceeds the original specification by 2.4x, providing enhanced reliability for replacement applications.

100SP2T6B11M1QEH (E-Switch) - Secondary Substitute

This active production part offers 5A AC current rating and 120V AC voltage, which are marginally below the original 6A/125V specification but acceptable for most applications operating below maximum rated conditions. The flat anti-rotation actuator provides enhanced mechanical stability. Electrical life of 40,000 cycles and ROHS3 compliance support long-term system reliability. Panel cutout diameter of 6.35mm requires verification against existing panel mounting holes.

7108P3YZQE (C&K) - Secondary Substitute

This part matches the E-Switch offering with 5A AC current and 120V AC voltage ratings. The flat anti-rotation actuator and 40,000-cycle electrical life provide equivalent performance characteristics. ROHS3 compliance is confirmed. REACH status is listed as affected, requiring verification of regulatory compliance for specific end-use applications.

2S1-MSP2-T4-B5-M1QE (Carling Technologies) - Limited Compatibility

This part provides 3A AC current rating, which matches the original DC specification but falls below the 6A AC requirement. The standard round actuator differs from the flatted design of the original. IP67 ingress protection rating provides enhanced environmental sealing not present in the original specification. This substitute is suitable only for applications where AC current demand does not exceed 3A.

Frequently Asked Questions (FAQ)

Q: Can the 100SP2T6B11M1QEH be used as a direct replacement for the M2015ES1W01?

A: The 100SP2T6B11M1QEH is functionally compatible for most applications. However, the 5A AC rating is below the original 6A specification. Verify that your circuit operates below 5A AC to ensure safe operation. The 120V AC rating is 5V below the original 125V specification. Panel cutout diameter of 6.35mm is 0.15mm smaller than the original 6.50mm; verify existing panel mounting holes accommodate this dimension.

Q: What is the difference between the A126P31YZQ and the original M2015ES1W01?

A: The A126P31YZQ provides superior electrical performance with matching 6A AC and 125V AC ratings. Actuator length is 11.38mm versus 11.40mm, a negligible 0.02mm difference. Operating temperature extends to 90°C versus 85°C. Electrical life is 60,000 cycles versus 25,000 cycles. Panel cutout dimensions are not specified for the A126P31YZQ; contact the manufacturer for confirmation of 6.50mm compatibility.

Q: Why does the 2S1-MSP2-T4-B5-M1QE have a lower current rating?

A: The 2S1-MSP2-T4-B5-M1QE is rated for 3A AC current, which aligns with the original part's 3A DC specification but does not meet the 6A AC requirement. This part is suitable only for applications where AC current demand does not exceed 3A. The IP67 ingress protection rating indicates this design prioritizes environmental sealing over high-current capacity.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts carry RoHS compliance certification. The A126P31YZQ is listed as RoHS Compliant (general designation). The 100SP2T6B11M1QEH, 2S1-MSP2-T4-B5-M1QE, and 7108P3YZQE are all ROHS3 Compliant, indicating compliance with the third iteration of RoHS regulations. Verify specific REACH status requirements for your application, as the 7108P3YZQE lists REACH status as affected.

Q: What is the significance of the flat anti-rotation actuator design?

A: The flat anti-rotation actuator (used in 100SP2T6B11M1QEH and 7108P3YZQE) provides mechanical resistance to unintended rotation during panel mounting and operation. The original M2015ES1W01 and A126P31YZQ use a flatted actuator design without explicit anti-rotation features. Both designs are mechanically compatible with 1/4-40 bushing threads; selection depends on application requirements for actuator stability.

Q: Can I use the 7108P3YZQE if REACH compliance is a concern?

A: The 7108P3YZQE lists REACH status as affected, meaning certain substances in the component may be subject to REACH regulations. Verify with the manufacturer whether specific restricted substances are present and whether exemptions or authorizations apply to your end-use application. The A126P31YZQ lists REACH status as vendor undefined; contact Electroswitch for clarification. The 100SP2T6B11M1QEH and 2S1-MSP2-T4-B5-M1QE list REACH status as unaffected.

Q: What is the impact of different electrical life ratings?

A: The original M2015ES1W01 is rated for 25,000 electrical cycles. Substitute parts offer 30,000 to 60,000 cycles, indicating extended operational life. Higher cycle ratings provide greater reliability margin for applications with frequent switching. The A126P31YZQ at 60,000 cycles provides 2.4x the original specification, suitable for high-cycle-count applications. For low-cycle applications, all substitutes exceed minimum requirements.
