C&K 7203L2YCQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203L2YCQE is an active-status toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with PC pin termination and is designed for on-off-on switching applications. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs while maintaining functional compatibility within electrical and mechanical parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203L2YCQE is determined by strict alignment of the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Mounting type must be Panel Mount
• Actuator type must be Standard Round
• Termination style must be PC Pin
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Operating temperature range must encompass -30°C to 85°C
• Electrical life must meet or exceed 40,000 cycles
• RoHS3 compliance is required

The E-Switch 100DP3T1B1M2REH meets all mechanical and functional compatibility criteria. However, electrical ratings differ significantly: the substitute part is rated for 0.4VA at 20V (both AC and DC), compared to the main part's 5A at 120V AC and 28V DC. This electrical rating differential must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch 100DP3T1B1M2REH provides mechanical and functional compatibility with the C&K 7203L2YCQE for panel-mount DPDT on-off-on switching applications. Both parts maintain ROHS3 compliance and identical operating temperature ranges and electrical life specifications.

Selection between these parts must account for electrical rating requirements. The 7203L2YCQE supports higher current (5A) and voltage (120V AC, 28V DC) applications, while the 100DP3T1B1M2REH is rated for lower power applications (0.4VA at 20V AC/DC). The REACH compliance difference should be evaluated based on regulatory requirements for the end application and geographic market.

Actuator length differs between parts (13.97mm versus 10.41mm), which may affect panel aesthetics and operator feel but does not impact electrical function.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M2REH directly replace the C&K 7203L2YCQE in all applications?

A: Mechanical and functional compatibility is confirmed. However, electrical rating compatibility must be verified. The substitute part is rated for 0.4VA at 20V maximum, while the main part supports 5A at 120V AC and 28V DC. Substitution is valid only for applications operating within the lower electrical ratings.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts feature a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount installations.

Q: What is the significance of the actuator length difference?

A: The C&K part has a 13.97mm actuator length compared to 10.41mm for the E-Switch part. This difference affects the physical protrusion from the panel surface but does not impact electrical switching performance or circuit compatibility.

Q: Does REACH compliance status affect substitution eligibility?

A: REACH compliance is a regulatory consideration dependent on end-use application and geographic market. The C&K part is REACH Affected, while the E-Switch part is REACH Unaffected. Regulatory requirements for your specific application determine whether this difference is material to your selection.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the C&K 7203L2YCQE and E-Switch 100DP3T1B1M2REH maintain ROHS3 compliance.

Q: What is the electrical life specification for both parts?

A: Both parts are rated for 40,000 electrical cycles, providing equivalent operational durability.
