M2018WBW01 Equivalent & Substitute Parts

Part Overview

The M2018WBW01 is a toggle switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with momentary-off-momentary (Mom-Off-Mom) switching function. This panel-mount component is rated for 6A at 125V AC and 3A at 30V DC, with IP67 ingress protection and waterproof boot design. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this switching topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2018WBW01 is determined by strict alignment with the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (6A/125V AC minimum; 3A/30V DC minimum)
• Mounting type (Panel Mount)
• Mechanical interface (M12 x 1 bushing thread, 12.50mm circular cutout)
• Actuator specifications (Standard Round, 20.00mm length)
• Termination style (Solder Lug)
• Environmental protection (IP67 minimum)
• Operating temperature range (-30°C to 85°C)
• Electrical life (25,000 cycles minimum)

The MN18WBW01 qualifies as a manufacturer-recommended substitute based on compatibility with these core parameters.
