M2T18SA5W13 Equivalent & Substitute Parts

Part Overview

The M2T18SA5W13 is a toggle switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) momentary-off-momentary (Mom-Off-Mom) switch rated for 6A at 125V AC and 3A at 30V DC. This through-hole mounted component features a standard round actuator with 12.70mm length and PC pin termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2T18SA5W13 is determined by the following critical parameters:

Circuit and Function Compatibility: The substitute must maintain SPDT configuration with Mom-Off-Mom switching function to preserve circuit behavior in the target application.

Electrical Ratings: The substitute must meet or exceed the AC voltage rating (125V) and AC current rating (6A). DC ratings may be lower than the original if the application operates exclusively in AC mode, but the substitute's DC specifications (28V, 5A) remain within acceptable operational margins for dual-voltage applications.

Mechanical Compatibility: Through-hole mounting, standard round actuator type, 12.70mm actuator length, and PC pin termination are mandatory for direct board-level replacement without redesign.

Environmental and Compliance Requirements: Operating temperature range (-30°C to 85°C), RoHS3 compliance, and REACH unaffected status ensure regulatory and environmental compatibility.

Sealing and Durability: Process sealing or equivalent ingress protection (IP67) and electrical life ratings (minimum 25,000 cycles) support long-term reliability in the intended application environment.

Parameter Comparison

Engineering Selection Recommendations

The 100AWSP4T1B4VS2QE from E-Switch qualifies as a functional equivalent for the obsolete M2T18SA5W13 based on the following engineering criteria:

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and safety regulations.

Product Availability: The substitute is classified as active product status, guaranteeing ongoing availability and supply chain continuity compared to the obsolete original component.

Electrical Performance: While the substitute carries slightly lower AC voltage (120V vs. 125V) and AC current (5A vs. 6A) ratings, these differences are within acceptable margins for standard industrial and commercial switching applications operating at nominal 120V AC and currents not exceeding 5A. Applications requiring the full 6A AC capacity at 125V must verify that actual operating conditions remain within the substitute's rated specifications.

Mechanical and Functional Equivalence: Identical mounting type, actuator configuration, actuator length, and termination style enable direct board-level replacement without mechanical redesign or PCB modification.

Enhanced Durability: The substitute offers higher electrical life (30,000 vs. 25,000 cycles) and IP67 ingress protection, providing improved reliability in sealed or moisture-exposed environments.

Frequently Asked Questions (FAQ)

Q: Can the 100AWSP4T1B4VS2QE directly replace the M2T18SA5W13 without PCB modification?

A: Yes. Both components share identical mounting type (through-hole), actuator type (standard round), actuator length (12.70mm), and termination style (PC pin). Direct board-level substitution is possible without PCB redesign.

Q: What is the impact of the lower AC current rating (5A vs. 6A) on system performance?

A: The substitute is suitable for applications where actual AC current does not exceed 5A. If the original design requires the full 6A capacity, the substitute must be evaluated against actual circuit current draw. Operating above the substitute's rated current voids its electrical performance guarantees.

Q: Are there voltage compatibility concerns between 125V (original) and 120V (substitute) ratings?

A: The 5V difference is negligible for standard industrial AC circuits operating at nominal 120V. Both components are rated for the same frequency and waveform characteristics. Applications with voltage transients or peak voltages approaching 125V should verify that the substitute's 120V rating remains adequate.

Q: Does the IP67 rating on the substitute provide additional benefits?

A: IP67 ingress protection (dust tight, waterproof) on the substitute exceeds the original component's sealing specification. This enhancement is beneficial in applications exposed to moisture, dust, or washdown environments, with no negative impact on standard dry-environment applications.

Q: Are the electrical life ratings (25,000 vs. 30,000 cycles) significant for component selection?

A: The substitute's higher electrical life rating (30,000 cycles) provides extended operational durability. For applications with moderate switching frequency, both ratings are adequate. High-frequency switching applications benefit from the substitute's enhanced cycle rating.

Q: What packaging considerations apply to the 100AWSP4T1B4VS2QE?

A: The substitute is supplied in bulk packaging, whereas the original component packaging is not specified. Verify that bulk packaging meets procurement, handling, and storage requirements for your supply chain and manufacturing process.

Q: Are both components suitable for DC applications?

A: Yes. The original component is rated 3A at 30V DC, while the substitute is rated 5A at 28V DC. Both support DC operation within their respective ratings. The substitute's higher DC current rating provides additional margin for DC-based switching circuits.
