C&K 7101P3DV3ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101P3DV3ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a flat anti-rotation actuator, epoxy sealed terminals, and operates across a temperature range of -30°C to 85°C with an electrical life of 100,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC / 28V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C

Substitute Categories:

Direct Manufacturer Equivalent: Parts from C&K with identical electrical and mechanical specifications but different product status (Active vs. Obsolete).

Cross-Manufacturer Substitutes: Parts from E-Switch that meet all primary matching criteria, enabling functional replacement in applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The C&K 7101P3DV3SE is the primary substitute for the obsolete 7101P3DV3ME. Both parts share identical electrical ratings, mechanical dimensions, and operating specifications. The 7101P3DV3SE maintains Active product status and ROHS3 compliance. The difference in REACH status (Affected vs. Unaffected) must be evaluated against specific regulatory requirements for your application region.

For Cross-Manufacturer Substitution: The E-Switch 100SP1T1B1VS2QEH meets all critical electrical and mechanical parameters required for functional equivalence. This part is Active and ROHS3 compliant. The electrical life specification differs (40,000 cycles vs. 100,000 cycles), which should be considered for applications requiring extended cycle life. REACH status is Unaffected, aligning with the original part specification.

Compliance Considerations: Both substitute parts maintain RoHS compliance suitable for regulated markets. REACH status differences require assessment based on your supply chain and end-market requirements.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101P3DV3SE directly replace the obsolete 7101P3DV3ME? A: Yes. The 7101P3DV3SE is a direct equivalent with identical electrical ratings (5A, 120V AC, 28V DC), mechanical dimensions (6.35mm circular cutout, 1/4-40 bushing), and operating temperature range (-30°C to 85°C). Both use PC pin termination and feature epoxy sealed terminals.

Q: What are the key differences between the C&K and E-Switch substitutes? A: The C&K 7101P3DV3SE is a direct manufacturer equivalent. The E-Switch 100SP1T1B1VS2QEH is a cross-manufacturer substitute that matches all critical electrical and mechanical specifications but has a lower electrical life rating (40,000 cycles vs. 100,000 cycles). Actuator design differs (flat anti-rotation vs. standard round), though both maintain the same panel cutout and bushing specifications.

Q: Does the difference in electrical life affect compatibility? A: Electrical life indicates the number of switching cycles before performance degradation. The E-Switch substitute (40,000 cycles) has lower cycle endurance than the original (100,000 cycles). For applications with high switching frequency or extended operational life requirements, the C&K 7101P3DV3SE is recommended.

Q: Are there REACH or RoHS compliance concerns with substitution? A: Both substitutes are RoHS compliant. The C&K 7101P3DV3SE has REACH Affected status, while the original and E-Switch substitute have REACH Unaffected status. Verify REACH requirements for your specific application and supply chain.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and electrical specifications (5A, 120V AC, 28V DC) match your design. Verify actuator type compatibility with your mechanical interface, as the original uses flat anti-rotation while the E-Switch uses standard round actuator.
