M2018SS4W01 Equivalent & Substitute Parts

Part Overview

The M2018SS4W01 is a toggle switch manufactured by NKK Switches, configured as a momentary-off-momentary (Mom-Off-Mom) SPDT panel mount switch. This component is rated for 6A at 125V AC and 3A at 30V DC, with a standard round actuator and solder lug termination. The product 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 eligibility for the M2018SS4W01 is determined by 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)
• Actuator type and length (Standard Round, 10.50mm)
• Termination style (Solder Lug)
• Panel cutout and bushing dimensions (Circular 6.50mm Dia, M6 x 0.75)
• Operating temperature range (-30°C ~ 85°C)
• Regulatory compliance (ROHS3 Compliant)

The MN18SS4W01 is identified as a manufacturer-recommended substitute based on compatibility with these core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MN18SS4W01 is designated as the manufacturer-recommended substitute for the obsolete M2018SS4W01. Both components are manufactured by NKK Switches and share identical ECCN and HTSUS classifications, confirming regulatory alignment. The substitute maintains ROHS3 compliance, meeting current environmental standards.

The transition from the obsolete M2018SS4W01 to the active MN18SS4W01 is supported by the manufacturer's direct recommendation. Component selection should be based on verification that the substitute meets the specific electrical and mechanical requirements of the application, with particular attention to the parameters listed in the Key Parameters table.

Frequently Asked Questions (FAQ)

Q: What makes MN18SS4W01 a valid substitute for M2018SS4W01?

A: The MN18SS4W01 is the manufacturer-recommended substitute designated by NKK Switches. Both components share the same ECCN and HTSUS classifications and maintain ROHS3 compliance. The substitute is currently in active production status, addressing the obsolescence of the original part.

Q: Are there any differences in electrical ratings between these parts?

A: Complete electrical specifications for the MN18SS4W01 are not provided in the available data. Verification of current and voltage ratings against application requirements is necessary before implementation.

Q: What are the critical mechanical compatibility factors?

A: Panel mount configuration, actuator type, panel cutout dimensions (Circular 6.50mm Dia), and bushing thread specification (M6 x 0.75) are the primary mechanical parameters determining substitution compatibility. These must align with the existing mechanical interface.

Q: Is the substitute available in the same packaging format?

A: Both components are available in bulk packaging. Inventory availability should be confirmed with the supplier for specific procurement requirements.

Q: Do both parts meet current regulatory requirements?

A: Both the M2018SS4W01 and MN18SS4W01 are ROHS3 compliant and carry the same ECCN classification (EAR99), confirming alignment with current regulatory standards.
