C&K 7101P4HCLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101P4HCLE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features a flat anti-rotation actuator, epoxy sealed terminals, and PC pin termination. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101P4HCLE is determined by the following critical parameters:

• Circuit Configuration: SPDT (mandatory match)
• Switch Function: On-On (mandatory match)
• Mounting Type: Panel Mount (mandatory match)
• Termination Style: PC Pin (mandatory match)
• Bushing Thread: 1/4-40 (mandatory match)
• Current Rating: 5A minimum (AC/DC)
• Voltage Rating - AC: 120V minimum
• Voltage Rating - DC: 28V minimum
• Actuator Length: 6.35mm nominal
• Panel Cutout Dimensions: Circular - 6.35mm Dia (mandatory match)

Substitute parts are grouped into two categories:

Direct Equivalent: Parts that maintain identical electrical and mechanical specifications with active product status.

Similar Substitute: Parts that meet or exceed the core electrical requirements (current, voltage) and mechanical interface specifications, with allowable variations in actuator type, electrical life, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - C&K 7101P4HCRE

The 7101P4HCRE is the direct equivalent to the 7101P4HCLE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), mechanical interface specifications, and actuator configuration. The 7101P4HCRE maintains active product status and RoHS compliance, making it the primary replacement for obsolete 7101P4HCLE applications. REACH status differs (REACH Affected vs. REACH Unaffected), requiring compliance verification for specific end-use applications.

Similar Substitute - Electroswitch A123S1HCQ

The A123S1HCQ exceeds the current rating requirement (6A vs. 5A) and matches the AC voltage specification (125V vs. 120V). This part is suitable for applications where the 5A rating is a design margin rather than a hard limit. The actuator length (10.41mm) differs from the original specification, requiring mechanical clearance verification in the panel assembly. Electrical life is reduced to 60,000 cycles. RoHS compliance and active product status are confirmed.

Similar Substitute - Electroswitch A123P41HCB

The A123P41HCB is not suitable as a direct substitute due to insufficient current rating (0.5VA vs. 5A required). This part is applicable only in low-power applications where the original 5A specification exceeds system requirements.

Similar Substitute - TE Connectivity MTM106DPC

The MTM106DPC meets the current requirement for AC applications (6A AC vs. 5A) but provides reduced DC current (4A DC vs. 5A). This part is suitable for AC-dominant applications. The panel cutout dimension (6.40mm vs. 6.35mm) represents a minor mechanical variation within typical manufacturing tolerances. RoHS non-compliance and REACH Affected status require regulatory assessment. Electrical life is 80,000 cycles, and operating temperature range is narrower (-20°C to 80°C vs. -30°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the 7101P4HCRE be used as a direct replacement for the 7101P4HCLE?

A: Yes. The 7101P4HCRE is the direct equivalent with identical electrical and mechanical specifications. The primary difference is active product status and REACH compliance status, which must be evaluated for your specific application requirements.

Q: What is the key limitation of the Electroswitch A123P41HCB?

A: The A123P41HCB has a current rating of 0.5VA, which is significantly below the 5A requirement of the 7101P4HCLE. This part is not suitable for applications requiring the full 5A capacity.

Q: Can the A123S1HCQ be used in place of the 7101P4HCLE?

A: The A123S1HCQ meets the electrical requirements (6A at 125V AC / 28V DC) and mechanical interface specifications. However, the actuator length is 10.41mm compared to 6.35mm on the original part. Mechanical clearance in the panel assembly must be verified before implementation.

Q: What are the compliance differences between substitute parts?

A: The 7101P4HCRE and Electroswitch parts are RoHS compliant. The MTM106DPC is RoHS non-compliant. REACH status varies: 7101P4HCLE is REACH Unaffected, 7101P4HCRE is REACH Affected, and Electroswitch parts have Vendor Undefined status. Regulatory requirements for your end application determine which compliance status is acceptable.

Q: Is the MTM106DPC suitable for DC applications?

A: The MTM106DPC provides 4A DC rating compared to the 5A DC requirement of the 7101P4HCLE. This part is suitable for DC applications where the current requirement does not exceed 4A. For full 5A DC operation, the 7101P4HCRE or A123S1HCQ are preferred.

Q: What is the impact of reduced electrical life in substitute parts?

A: The 7101P4HCLE and 7101P4HCRE are rated for 100,000 cycles. The Electroswitch parts are rated for 60,000 cycles, and the MTM106DPC for 80,000 cycles. Applications with high cycle counts should prioritize parts with higher electrical life ratings or implement preventive maintenance schedules accordingly.

Q: Are there packaging differences between the main part and substitutes?

A: The 7101P4HCLE packaging is listed as dash (standard). Electroswitch substitutes are supplied in bulk packaging. TE Connectivity MTM106DPC is also supplied in bulk. Packaging format does not affect electrical or mechanical compatibility.
