C&K 7103P3YCQES Toggle Switch SPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7103P3YCQES is an active production toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a flat anti-rotation actuator with satin chrome finish and is designed for On-Off-On switching applications. The part is ROHS3 compliant and carries REACH Affected status. Substitute parts are identified when equivalent electrical ratings, circuit topology, mounting configuration, and termination style align with the original specification, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3YCQES is determined by strict alignment of the following critical parameters:

• Circuit Configuration: SPDT topology required for functional equivalence
• Switch Function: On-Off-On operation mandatory
• Current Rating: 5A (AC/DC) minimum
• Voltage Ratings: 120V AC and 28V DC minimum
• Mounting Type: Panel Mount configuration
• Termination Style: PC Pin connections
• Panel Cutout Dimensions: Circular 6.35mm diameter for mechanical fit
• Bushing Thread: 1/4-40 for panel assembly compatibility
• Operating Temperature Range: -30°C to 85°C operational envelope
• Electrical Life: 40,000 cycles minimum

The E-Switch 100SP3T1B1M2QEH meets all critical substitution criteria. Both parts share identical electrical specifications, circuit topology, mounting configuration, termination style, and panel interface dimensions. Differences in actuator type (flat anti-rotation versus standard round) and actuator length (11.43mm versus 10.41mm) do not affect functional substitution when panel cutout and bushing thread specifications remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7103P3YCQES and E-Switch 100SP3T1B1M2QEH are active production parts with ROHS3 compliance. Selection between these parts should be based on the following factors:

C&K 7103P3YCQES: Preferred when flat anti-rotation actuator geometry is specified in the application design or when the 11.43mm actuator length is required for panel clearance or user interface consistency.

E-Switch 100SP3T1B1M2QEH: Suitable as a direct substitute when standard round actuator geometry is acceptable and the 10.41mm actuator length accommodates the application panel assembly. This part features epoxy sealed terminals, providing enhanced environmental protection compared to the satin chrome actuator finish of the original part.

Both parts carry identical electrical ratings, circuit topology, and mechanical interface specifications. The choice between them does not affect electrical performance or functional compatibility in SPDT On-Off-On switching applications within the specified voltage and current ranges.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP3T1B1M2QEH replace the C&K 7103P3YCQES in existing designs?

A: Yes, the E-Switch part is a direct electrical and mechanical substitute. Both parts share identical SPDT circuit configuration, 5A current rating, 120V AC / 28V DC voltage ratings, panel cutout dimensions (6.35mm circular), and 1/4-40 bushing thread. The primary differences are actuator type and length, which do not affect functional substitution when the panel interface remains unchanged.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires matching circuit configuration (SPDT), switch function (On-Off-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (panel mount), termination style (PC pin), panel cutout dimensions (6.35mm circular), and bushing thread (1/4-40). Operating temperature range and electrical life specifications must also align.

Q: Are there differences in actuator design between these parts?

A: Yes. The C&K 7103P3YCQES features a flat anti-rotation actuator (11.43mm length) with satin chrome finish, while the E-Switch 100SP3T1B1M2QEH has a standard round actuator (10.41mm length) with epoxy sealed terminals. These design differences do not affect electrical performance or circuit operation.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant. The C&K part carries REACH Affected status, while the E-Switch part is REACH Unaffected. Compliance requirements should be verified against your specific application and regional regulations.

Q: What is the panel assembly compatibility between these parts?

A: Both parts are fully compatible for panel assembly. They share identical panel cutout dimensions (circular 6.35mm diameter) and bushing thread specification (1/4-40). The difference in actuator length (11.43mm versus 10.41mm) may affect panel clearance or user interface appearance but does not prevent mechanical installation.
