M2012E4S4W01 Equivalent & Substitute Parts

Part Overview

The M2012E4S4W01 is a toggle switch manufactured by NKK Switches, classified as a SPDT (Single Pole Double Throw) panel mount switch with a flatted actuator. This component is rated for 6A AC at 125V and 4A DC at 30V, featuring epoxy sealed terminals and non-illuminated operation. The part is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where this switch is specified in legacy equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2012E4S4W01 is determined by strict equivalence across the following critical parameters:

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

The M2012ES4W01 qualifies as a direct substitute based on full alignment with these parameters. The primary difference is the actuator length (11.40mm versus 21.30mm on the original), which does not affect electrical or mechanical compatibility within the specified panel mount interface.

Parameter Comparison

Engineering Selection Recommendations

The M2012ES4W01 is a direct electrical and mechanical substitute for the M2012E4S4W01. Both components maintain identical electrical specifications, compliance certifications (ROHS3), and panel mount interface requirements. The actuator length difference does not impact compatibility when the panel cutout and bushing thread specifications are maintained.

Selection between these parts should be based on physical space constraints within the equipment enclosure. The shorter actuator length of the M2012ES4W01 (11.40mm) may be advantageous in applications with limited panel depth, while the longer actuator of the M2012E4S4W01 (21.30mm) provides extended reach for operator accessibility.

Both parts are classified as obsolete. Availability should be confirmed with the component supplier prior to procurement.

Frequently Asked Questions (FAQ)

Q: Can the M2012ES4W01 be used as a direct replacement for the M2012E4S4W01?

A: Yes. The M2012ES4W01 meets all electrical and mechanical specifications required for substitution. The primary difference is actuator length, which does not affect circuit performance or panel mount compatibility.

Q: What is the significance of the actuator length difference?

A: Actuator length affects operator reach and tactile feedback distance. The M2012E4S4W01 has a 21.30mm actuator, while the M2012ES4W01 has an 11.40mm actuator. Both are compatible with the same panel cutout (6.50mm Dia) and bushing thread (M6 x 0.75). Selection depends on available panel depth and ergonomic requirements.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 6A AC at 125V and 4A DC at 30V. They share identical SPDT circuit configuration, On-On switch function, and 25,000 cycle electrical life rating.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the M2012E4S4W01 and M2012ES4W01 are ROHS3 compliant and carry identical environmental certifications.

Q: What should be considered when selecting between these substitutes?

A: Verify panel depth availability for the actuator length. Confirm solder lug termination compatibility with your PCB or wiring harness. Both parts operate across the same temperature range (-30°C to 85°C) and are suitable for equivalent applications.
