M2042SS4W01 Equivalent & Substitute Parts

Part Overview

The M2042SS4W01 is a toggle switch manufactured by NKK Switches, configured as a 4PDT (four-pole double-throw) panel mount switch with a 6A AC / 4A DC current rating at 125V AC / 30V DC. This switch features a standard round actuator with solder lug termination and is sealed with epoxy for terminal protection. The product is currently classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2042SS4W01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-On)
• Current and voltage ratings (6A AC / 125V AC minimum; 4A DC / 30V DC minimum)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 10.50mm)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Bushing thread specification (M6 x 0.75)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (25,000 Cycles)
• Regulatory compliance (ROHS3 Compliant)

The substitute part MN42SS4W01 is identified as the manufacturer-recommended equivalent based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The M2042SS4W01 is designated as obsolete. The manufacturer-recommended substitute is MN42SS4W01, which is classified as active product status. Both parts are manufactured by NKK Switches and share identical ROHS3 compliance and export classification (EAR99). The transition from M2042SS4W01 to MN42SS4W01 is supported by the manufacturer's substitution designation.

Selection of MN42SS4W01 is appropriate for applications requiring continued supply of 4PDT toggle switch functionality with panel mount configuration. Verification of complete electrical and mechanical parameter alignment with system requirements is necessary prior to design implementation.

Frequently Asked Questions (FAQ)

Q: Why is the M2042SS4W01 being phased out? A: The M2042SS4W01 is classified as obsolete by the manufacturer. MN42SS4W01 is the active replacement part.
