C&K 7105P1CWCKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105P1CWCKE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component features a momentary-off-momentary (Mom-Off-Mom) switch function with IP67 ingress protection and epoxy-sealed terminals for harsh environment applications. The part is currently classified as obsolete, making identification of active equivalent models essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7105P1CWCKE is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA AC/DC), and voltage ratings (20V AC/DC) must be identical.

Mechanical Parameters: Mounting type (panel mount), actuator type (flat anti-rotation), actuator length (21.33mm), panel cutout dimensions (circular 6.35mm diameter), bushing thread (1/4-40), and termination style (PC pin) must match exactly.

Environmental Specifications: Ingress protection rating (IP67), operating temperature range (-30°C to 85°C), and sealed terminal construction must be preserved.

Series Compatibility: Both parts belong to the C&K 7000 series, ensuring design and form factor consistency.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105P1CWCPE is a direct functional equivalent to the obsolete 7105P1CWCKE. Both components share identical electrical ratings, mechanical dimensions, and environmental specifications. The primary distinction is product status: the 7105P1CWCPE is currently in active production, ensuring availability for new designs and replacement inventory.

Compliance considerations: The 7105P1CWCPE maintains RoHS compliance and carries EAR99 export classification identical to the original part. The REACH status differs (REACH Affected versus REACH Unaffected), which may require evaluation based on end-use application and regional regulatory requirements.

For applications requiring the exact original specification, the 7105P1CWCPE provides complete electrical and mechanical interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 7105P1CWCPE directly replace the 7105P1CWCKE in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters, including circuit configuration, voltage and current ratings, panel cutout dimensions, and termination style. No PCB or panel modifications are required.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The 7105P1CWCKE is obsolete, while the 7105P1CWCPE is actively manufactured. Both belong to the C&K 7000 series and share identical functional specifications.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 export classification. The REACH status differs: 7105P1CWCKE is REACH Unaffected, while 7105P1CWCPE is REACH Affected. Applications subject to REACH regulations should evaluate this distinction.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: SPDT circuit, Mom-Off-Mom function, 0.4VA current rating, 20V AC/DC voltage rating, panel mount configuration, flat anti-rotation actuator, 21.33mm actuator length, 6.35mm circular panel cutout, 1/4-40 bushing thread, PC pin termination, and IP67 ingress protection.

Q: Is the 7105P1CWCPE available in the same packaging?

A: Both parts use identical PC pin termination and panel mount configuration. Packaging specifications are consistent between the two variants.
