C&K 7105P1CWWLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105P1CWWLE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch features a momentary-off-momentary (Mom-Off-Mom) function with a flat anti-rotation actuator and wire wrap termination. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7105P1CWWLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type and panel cutout dimensions (Panel Mount, 6.35mm circular, 1/4-40 bushing thread)
• Actuator specifications (Flat Anti-Rotation, 21.33mm length)
• Termination style (Wire Wrap)
• Environmental protection (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7105P1CWWRE qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction lies in product status and regulatory compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105P1CWWRE is a direct functional equivalent to the 7105P1CWWLE. Both components share identical electrical specifications, mechanical dimensions, and environmental ratings. The 7105P1CWWRE is the preferred selection for new designs and ongoing procurement due to its active product status. For legacy system maintenance where the original 7105P1CWWLE is no longer available, the 7105P1CWWRE provides complete electrical and mechanical compatibility without design modification.

Regulatory compliance differs between the two parts: the 7105P1CWWLE carries RoHS3 Compliant status with REACH Unaffected designation, while the 7105P1CWWRE is RoHS Compliant with REACH Affected status. Component selection should account for applicable regulatory requirements in the target application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can the 7105P1CWWRE directly replace the 7105P1CWWLE in existing assemblies?

A: Yes. Both components are mechanically and electrically identical across all functional parameters. Panel cutout dimensions, bushing thread specifications, actuator geometry, and electrical ratings are equivalent. No design modification or panel rework is required.

Q: What is the difference between RoHS3 Compliant and RoHS Compliant designations?

A: RoHS3 Compliant refers to compliance with the third iteration of the Restriction of Hazardous Substances directive. RoHS Compliant indicates general RoHS compliance. Both designations confirm restriction of hazardous substances; the specific version designation reflects the regulatory framework under which compliance was assessed.

Q: Does the REACH Affected status of the 7105P1CWWRE affect its use in applications where the 7105P1CWWLE was previously used?

A: REACH Affected status indicates the component contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This status does not prevent component use but requires compliance with applicable REACH requirements in the target market. Applications must confirm REACH compliance requirements for their specific geographic and regulatory context.

Q: Are the wire wrap terminations identical between both parts?

A: Yes. Both the 7105P1CWWLE and 7105P1CWWRE use identical wire wrap termination specifications. Existing wire wrap tooling and assembly procedures are compatible with both components.

Q: What is the significance of the 40,000-cycle electrical life rating?

A: The 40,000-cycle electrical life rating specifies the number of complete switch cycles (actuations) the component is rated to perform under specified electrical load conditions before degradation. This rating applies to both the main part and substitute.
