M2T22S4A5W30 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The M2T22S4A5W30 is a DPDT (Double Pole Double Throw) toggle switch manufactured by NKK Switches, rated for 6A at 125V AC and 4A at 30V DC. This through-hole, right-angle mounted switch features a standard round actuator and is sealed for process protection. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Substitute parts must maintain electrical compatibility while meeting the same mechanical and environmental requirements.

Engineering Selection Recommendations

WT223M1D1AG (Electroswitch) is the primary direct substitute. It matches the M2T22S4A5W30 in electrical ratings (6A/125V AC, 6A/28V DC), mounting configuration, and actuator type. The part is active in production with RoHS compliance. Electrical life is extended to 60,000 cycles compared to the original 25,000 cycles. DC voltage rating is 28V versus the original 30V, which is acceptable for most applications operating below 28V.

100AWDP1T2B4M6QE (E-Switch) provides a secondary option with slightly reduced AC current rating (5A versus 6A) and AC voltage rating (120V versus 125V). This part includes IP67 ingress protection and epoxy-sealed terminals, offering enhanced environmental sealing. Electrical life reaches 30,000 cycles. Suitable for applications not requiring the full 6A/125V specification.

7201P4D9AGE (C&K) offers equivalent electrical performance (5A/120V AC) with extended electrical life (100,000 cycles). The flat anti-rotation actuator differs mechanically from the standard round type, requiring panel cutout verification. Actuator length is 8.13mm versus 7.62mm, which may affect mechanical fit.

7201P4D9ABE, 7201P4D9ABES, and E201MD1ABE are low-power alternatives rated for 0.4VA at 20V. These parts are suitable only for applications with significantly reduced electrical requirements and are not recommended as direct replacements for the M2T22S4A5W30 in high-current applications.

All substitute parts maintain DPDT On-On configuration, PC pin termination, through-hole right-angle mounting, and -30°C to 85°C operating temperature range. All are RoHS3 compliant or RoHS compliant.

Frequently Asked Questions (FAQ)

Q: Can WT223M1D1AG directly replace M2T22S4A5W30 in all applications?

A: WT223M1D1AG is the closest electrical equivalent with matching 6A/125V AC ratings and identical mounting configuration. The DC voltage rating is 28V versus the original 30V. Verify that your application operates at or below 28V DC. Mechanical fit should be confirmed due to identical actuator length (7.60mm vs 7.62mm).

Q: What is the difference between Category A and Category B substitutes?

A: Category A (WT223M1D1AG) maintains the full 6A/125V AC electrical specification. Category B substitutes (100AWDP1T2B4M6QE, 7201P4D9AGE) are rated for 5A/120V AC, suitable for applications not requiring the maximum current and voltage ratings. Category B parts should not be used in circuits designed for 6A at 125V.

Q: Why do some substitutes have different actuator types?

A: The C&K 7000 series parts (7201P4D9ABE, 7201P4D9ABES, 7201P4D9AGE) feature flat anti-rotation actuators instead of standard round types. This affects mechanical engagement with panel-mounted controls. Verify panel cutout compatibility and actuator length (8.13mm) before selection.

Q: Are low-power substitutes (0.4VA/20V) acceptable replacements?

A: No. Parts rated for 0.4VA at 20V (7201P4D9ABE, 7201P4D9ABES, E201MD1ABE) are not suitable for applications requiring 6A at 125V or 4A at 30V. These are appropriate only for low-signal switching applications with significantly reduced electrical demands.

Q: What compliance certifications apply to all substitutes?

A: All substitute parts are RoHS3 compliant or RoHS compliant and meet ECCN EAR99 classification. REACH status varies: Electroswitch parts show vendor undefined status, while C&K and E-Switch parts indicate REACH affected or unaffected status. Verify REACH compliance requirements for your specific application and region.

Q: Does actuator length affect mechanical compatibility?

A: Yes. The M2T22S4A5W30 has a 7.62mm actuator length. WT223M1D1AG matches at 7.60mm. C&K 7000 series parts are 8.13mm, which may require panel cutout adjustment. E-Switch 100AWDP1T2B4M6QE matches at 7.62mm. Measure existing panel cutouts before substitution.

Q: What is the electrical life difference between the original and substitutes?

A: M2T22S4A5W30 is rated for 25,000 cycles. Substitutes range from 30,000 cycles (E-Switch) to 100,000 cycles (C&K 7000 series). Extended electrical life in substitutes provides improved reliability and longer service intervals.

Q: Can I use 100AWDP1T2B4M6QE in a 6A/125V application?

A: No. 100AWDP1T2B4M6QE is rated for 5A/120V AC maximum. Using it in a 6A/125V circuit exceeds its electrical specification and may cause premature failure or safety hazards. Select WT223M1D1AG for full-specification replacement.
