M2018ES4W01 Equivalent & Substitute Parts

Part Overview

The M2018ES4W01 is a toggle switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) momentary-off-momentary switch with panel mount installation. This component is rated for 6A at 125V AC and 3A at 30V DC, featuring a flatted brass actuator with chrome plating and epoxy sealed solder lug terminals. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2018ES4W01 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: Momentary-off-momentary operation required
• Current and Voltage Ratings: Minimum 6A at 125V AC and 3A at 30V DC
• Mounting Interface: Panel mount with M6 x 0.75 bushing thread and 6.50mm circular cutout
• Termination: Solder lug connection style
• Actuator Geometry: Flatted actuator type with 11.40mm length
• Environmental Compliance: RoHS3 compliance and operating temperature range -30°C to 85°C

The substitute part MN18ES4W01 shares the same manufacturer (NKK Switches) and maintains electrical and mechanical compatibility within these defined parameters.

Engineering Selection Recommendations

The MN18ES4W01 is identified as the manufacturer-recommended substitute for the obsolete M2018ES4W01. Selection of this alternative is supported by:

• Active Product Status: MN18ES4W01 maintains active production status, ensuring availability and supply chain continuity
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, confirming equivalent export and tariff treatment
• Manufacturer Consistency: Both components are manufactured by NKK Switches, maintaining design and quality standards within the same product ecosystem

Complete electrical and mechanical parameter verification with the substitute part datasheet is necessary prior to final design implementation, as certain specifications are not provided in the available substitute data.

Frequently Asked Questions (FAQ)

Q: Can MN18ES4W01 be used as a direct replacement for M2018ES4W01?

A: MN18ES4W01 is the manufacturer-recommended substitute. However, complete parameter verification against the MN18ES4W01 datasheet is required to confirm all electrical ratings, mechanical dimensions, and functional characteristics match the application requirements.

Q: What is the primary reason for seeking a substitute?

A: The M2018ES4W01 is classified as obsolete. The MN18ES4W01 provides an active alternative from the same manufacturer to ensure continued component availability.

Q: Are there packaging differences between these parts?

A: The M2018ES4W01 is specified with dash packaging, while MN18ES4W01 is supplied in bulk packaging. Packaging format should be verified against procurement and assembly requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts share identical ECCN and HTSUS classifications. The M2018ES4W01 is confirmed ROHS3 compliant; RoHS status for MN18ES4W01 should be verified with the manufacturer datasheet.

Q: What parameters must be verified before substitution?

A: Current ratings (6A AC / 3A DC), voltage ratings (125V AC / 30V DC), circuit configuration (SPDT), switch function (Mom-Off-Mom), mounting interface (M6 x 0.75 panel mount), termination style (solder lug), and operating temperature range (-30°C to 85°C) must be confirmed in the substitute part specifications.
