C&K 7301SYCKE Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7301SYCKE is a 3PDT toggle switch rated for 0.4VA at 20V with panel mount configuration and PC pin termination. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features epoxy sealed terminals, brass chrome-plated actuator, and operates across -30°C to 85°C temperature range with 100,000 electrical cycle life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7301SYCKE is determined by the following critical parameters: circuit configuration (3PDT), switch function (On-On), mounting type (panel mount), termination style (PC pin), and bushing thread specification (1/4-40). Current and voltage ratings establish the operational envelope within which substitutes must function.

Two substitute categories are identified:

Direct Equivalent: Parts maintaining identical or superior electrical specifications and mechanical compatibility with the original design envelope.

Similar Alternative: Parts with compatible circuit and mounting characteristics but differing electrical ratings, requiring application-level verification of suitability.

Parameter Comparison

Engineering Selection Recommendations

7301SYCPE (C&K Direct Equivalent): This part is the primary substitute for 7301SYCKE applications. It maintains identical electrical ratings (0.4VA, 20V AC/DC), mechanical dimensions, and circuit configuration. The 7301SYCPE is active in production status and RoHS compliant, addressing regulatory requirements where the original part does not. Electrical life specification remains at 100,000 cycles. This substitute provides direct form-fit-function replacement with no design modification required.

A323S1YCB (Electroswitch Similar Alternative): This part shares 3PDT On-On configuration, panel mount, PC pin termination, and 1/4-40 bushing thread with the original. Current rating is marginally higher at 0.5VA versus 0.4VA, and voltage rating is elevated to 28V AC/DC. Operating temperature range extends to 90°C. Electrical life is reduced to 60,000 cycles. This substitute is suitable for applications where the original 0.4VA/20V envelope is not a hard constraint and the reduced cycle life is acceptable.

A323P31DCQ (Electroswitch Similar Alternative): This part provides 3PDT On-On configuration with panel mount and 1/4-40 bushing thread compatibility. Current rating is significantly higher at 6A, and voltage rating reaches 125V AC / 28V DC. Actuator type differs (flatted versus standard round), and actuator length is 11.38mm. Electrical life is 60,000 cycles. This substitute is applicable only where higher current and voltage capacity are required and mechanical actuator differences are acceptable.

Frequently Asked Questions (FAQ)

Q: Can 7301SYCPE directly replace 7301SYCKE without circuit modification?

A: Yes. The 7301SYCPE maintains identical electrical specifications (0.4VA, 20V AC/DC), circuit configuration (3PDT On-On), mechanical mounting (panel mount, 1/4-40 bushing), and termination style (PC pin). No circuit or mechanical redesign is required.

Q: What is the primary reason to substitute the 7301SYCKE?

A: The 7301SYCKE is classified as obsolete. The 7301SYCPE provides an active production equivalent with identical performance characteristics and improved RoHS compliance status.

Q: Are Electroswitch A323 series parts direct replacements?

A: No. A323 series parts are similar alternatives, not direct equivalents. They share circuit configuration (3PDT), mounting type (panel mount), and bushing thread (1/4-40), but differ in electrical ratings and cycle life. Application-specific evaluation is required to confirm suitability.

Q: What are the key differences between A323P31DCQ and A323S1YCB?

A: A323P31DCQ is rated for 6A at 125V AC with 28V DC capability, while A323S1YCB is rated for 0.5VA at 28V AC/DC. A323P31DCQ features a flatted actuator; A323S1YCB uses a standard round actuator. Both have 60,000 cycle electrical life and 1/4-40 bushing thread compatibility.

Q: Does the reduced electrical life of Electroswitch alternatives affect compatibility?

A: Electrical life reduction from 100,000 to 60,000 cycles is a specification difference that must be evaluated against application duty cycle requirements. If the application demands exceed 60,000 cycles, these alternatives are not suitable.

Q: Are all substitute parts RoHS compliant?

A: The 7301SYCKE is RoHS non-compliant. The 7301SYCPE is RoHS compliant. The Electroswitch A323 series parts are RoHS compliant. Regulatory requirements should guide substitute selection.
