M83731/10-321 Toggle Switch SP3T Equivalent & Substitute Parts

Part Overview

The M83731/10-321 is a panel-mount toggle switch with SP3T (single-pole, three-throw) circuit configuration manufactured by C&K. This switch is rated for 5A at 115V AC and 28V DC, featuring a standard round actuator with 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 M83731/10-321 is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Must be SP3T to maintain identical switching logic
• Current Rating: Must support minimum 5A (AC/DC)
• Voltage Rating - AC: Must support minimum 115V
• Voltage Rating - DC: Must support minimum 28V
• Mounting Type: Must be panel mount with identical mechanical interface
• Actuator Type and Length: Must be standard round, 10.41mm to ensure physical compatibility
• Termination Style: Must be solder lug for direct PCB integration
• Panel Cutout Dimensions: Must be circular 6.35mm diameter for panel compatibility
• Bushing Thread: Must be 1/4-40 for mounting consistency

The substitute part 100DP6T1B1M1QEH meets all critical substitution criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 100DP6T1B1M1QEH from E-Switch is a direct functional equivalent to the obsolete M83731/10-321. All critical electrical and mechanical parameters align or exceed the original specification. The substitute part offers enhanced performance characteristics, including extended operating temperature range (-30°C to 85°C versus -25°C to 71°C) and increased electrical life (40,000 cycles versus 10,000 cycles). Both parts maintain RoHS compliance and identical mechanical interfaces, ensuring drop-in compatibility in existing panel mount applications. The E-Switch part is currently in active production with confirmed inventory availability, eliminating supply chain risk associated with the obsolete C&K component.

Frequently Asked Questions (FAQ)

Q: Can the 100DP6T1B1M1QEH be used as a direct replacement for the M83731/10-321?

A: Yes. Both parts share identical circuit configuration (SP3T), current rating (5A AC/DC), voltage ratings (115V/120V AC, 28V DC), mechanical mounting interface (panel mount, 1/4-40 bushing thread), actuator specifications (standard round, 10.41mm length), and termination style (solder lug). All critical substitution parameters are met or exceeded.

Q: What are the key differences between these two parts?

A: The E-Switch substitute provides superior performance specifications. Operating temperature range extends from -30°C to 85°C (versus -25°C to 71°C), and electrical life increases to 40,000 cycles (versus 10,000 cycles). AC voltage rating is 120V instead of 115V. The substitute is current production while the original is obsolete.

Q: Are there any panel cutout or mounting modifications required?

A: No. Both parts feature identical panel cutout dimensions (circular 6.35mm diameter) and bushing thread specification (1/4-40), ensuring mechanical compatibility without panel modification.

Q: Do both parts require the jumper configuration for triple throw operation?

A: Yes. Both the M83731/10-321 and 100DP6T1B1M1QEH require a jumper to achieve triple throw functionality, as specified in their feature sets.

Q: What compliance certifications apply to the substitute part?

A: The 100DP6T1B1M1QEH is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.
