M2018TYW01-HA Equivalent & Substitute Parts

Part Overview

The M2018TYW01-HA is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with momentary-off-momentary (Mom-Off-Mom) switching function. This panel-mount component is rated for 6A AC at 125V and 3A DC at 30V, featuring a black paddle actuator with solder lug termination and epoxy-sealed terminals. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs requiring similar electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2018TYW01-HA is determined by electrical compatibility across the following critical parameters: circuit configuration (SPDT), switch function (Mom-Off-Mom), current and voltage ratings (6A AC/125V, 3A DC/30V), and mechanical interface specifications (panel mount with flange, paddle actuator, solder lug termination). The substitute part MN18TYW01-HA is identified as a manufacturer-recommended alternative from NKK Switches, sharing the same base product family (M/MN18TY series) and regulatory compliance profile (ROHS3, EAR99 classification).

The MN18TYW01-HA represents a design evolution within the NKK Switches rocker switch portfolio, maintaining electrical performance parameters while offering active product status and improved supply availability compared to the obsolete M2018TYW01-HA.

Parameter Comparison

Engineering Selection Recommendations

Selection between M2018TYW01-HA and MN18TYW01-HA should prioritize product lifecycle status and supply chain continuity. The M2018TYW01-HA, while currently in stock, carries obsolete designation, indicating discontinued manufacturing and limited future availability. The MN18TYW01-HA maintains active product status from the same manufacturer, ensuring long-term supply reliability and continued regulatory compliance under ROHS3 and EAR99 classifications.

Both parts maintain identical regulatory certifications and export control classifications, supporting direct substitution in applications where component lifecycle management and supply assurance are engineering requirements. Existing designs utilizing M2018TYW01-HA should transition to MN18TYW01-HA to mitigate obsolescence risk.

Frequently Asked Questions (FAQ)

Q: What electrical parameters determine compatibility between M2018TYW01-HA and MN18TYW01-HA?

A: Both parts share the same base product family designation (M/MN18TY series) from NKK Switches, indicating electrical equivalence in circuit configuration, switching function, and current/voltage ratings. Substitution is valid where the original application requires SPDT Mom-Off-Mom switching at 6A AC/125V or 3A DC/30V.

Q: Why is M2018TYW01-HA listed as obsolete if inventory is available?

A: Obsolete designation indicates the manufacturer has discontinued production. Current inventory represents remaining stock from prior manufacturing runs. Once depleted, the part will no longer be available through normal distribution channels, making transition to active alternatives necessary for long-term supply security.

Q: Are there packaging differences between these parts?

A: M2018TYW01-HA is supplied in Tray packaging, while MN18TYW01-HA is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection should be based on procurement and assembly process requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both M2018TYW01-HA and MN18TYW01-HA are ROHS3 compliant and classified under EAR99 export control. Both share identical HTSUS commodity code 8536.50.9065, confirming regulatory equivalence.

Q: What is the mechanical interface compatibility?

A: Substitution requires verification that panel cutout dimensions and mounting specifications of the application accommodate the substitute part's mechanical envelope. Detailed mechanical specifications for MN18TYW01-HA should be confirmed against application requirements prior to implementation.
