NKK Switches M2T28SA5A13 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The NKK Switches M2T28SA5A13 is a through-hole mounted toggle switch with DPDT (Double Pole Double Throw) circuit configuration and momentary-off-momentary switch function. Rated for 6A AC at 125V and 3A DC at 30V, this component is designed for applications requiring reliable electromechanical switching with process-sealed construction. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

The M2028SA2A13 qualifies as a substitute based on matching all critical electrical parameters, mechanical mounting specifications, and regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The M2028SA2A13 is a direct functional substitute for the obsolete M2T28SA5A13. Both components are manufactured by NKK Switches and maintain identical electrical ratings, mechanical mounting specifications, and regulatory compliance certifications. The substitute part is currently in active production status with confirmed inventory availability.

The M2028SA2A13 provides enhanced reliability through an extended electrical life specification of 50,000 cycles compared to the original part's 25,000 cycles. Both components maintain ROHS3 compliance and MSL Level 1 classification, ensuring compatibility with standard manufacturing and storage protocols.

Selection of the M2028SA2A13 is supported by matching circuit configuration (DPDT), switch function (Mom-Off-Mom), current and voltage ratings, through-hole mounting architecture, and PC pin termination. The active product status of the substitute ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the M2028SA2A13 be used as a direct replacement for the M2T28SA5A13 in existing designs?

A: Yes. Both components share identical electrical ratings (6A AC at 125V, 3A DC at 30V), DPDT circuit configuration, Mom-Off-Mom switch function, through-hole mounting, and PC pin termination. Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What is the difference in electrical life between these two parts?

A: The M2T28SA5A13 is rated for 25,000 electrical cycles, while the M2028SA2A13 is rated for 50,000 electrical cycles. The substitute part provides extended operational life for the same electrical and mechanical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the M2T28SA5A13 and M2028SA2A13 are ROHS3 compliant and carry MSL Level 1 moisture sensitivity classification.

Q: What is the actuator length difference between these parts?

A: The M2T28SA5A13 has an actuator length of 12.70mm, while the M2028SA2A13 has an actuator length of 12.28mm. This 0.42mm difference is within standard mechanical tolerance for toggle switch actuators and does not affect functional compatibility in standard through-hole PCB applications.

Q: Why is the original part listed as obsolete?

A: The M2T28SA5A13 is classified as obsolete by the manufacturer. The M2028SA2A13 represents the current active production equivalent with enhanced specifications and confirmed ongoing availability.

Q: Are there any differences in sealing or environmental protection?

A: The M2T28SA5A13 features process-sealed construction, while the M2028SA2A13 features epoxy-sealed terminals. Both provide adequate environmental protection for standard industrial and commercial applications within the specified operating temperature range of -30°C to 85°C.
