Engineering Selection Recommendations

C&K 7105P4HCRE (Direct Substitute - Preferred)

The 7105P4HCRE is the primary equivalent for the obsolete 7105P4HCLE. Both components share identical electrical specifications, mechanical dimensions, and actuator characteristics. The 7105P4HCRE maintains active product status with current manufacturing support. RoHS compliance is confirmed for both parts. The 7105P4HCRE is the recommended choice for direct replacement in existing designs and new applications requiring the 7105P4HCLE specification.

TE Connectivity 3-1825137-7 (Similar Substitute - Alternative)

The TE Connectivity 3-1825137-7 provides functional equivalence with matching electrical ratings, circuit configuration, and panel mount interface. This part operates within the same voltage and current parameters. Differences include a standard round actuator (versus flat anti-rotation) with increased length (10.41mm versus 6.35mm), and reduced electrical life rating (6,000 cycles versus 40,000 cycles). This component is suitable for applications where the mechanical actuator profile and reduced cycle life do not present design constraints. Both RoHS3 and REACH compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 7105P4HCRE directly replace the 7105P4HCLE without design modifications?

A: Yes. The 7105P4HCRE maintains identical electrical specifications, mechanical dimensions, panel cutout requirements, and termination style. No design modifications are required for direct substitution.

Q: What are the key differences between the 7105P4HCRE and the TE Connectivity 3-1825137-7?

A: Both parts meet the core electrical requirements (5A, 120V AC, 28V DC, SPDT, Mom-Off-Mom). The primary differences are: actuator type (flat anti-rotation versus standard round), actuator length (6.35mm versus 10.41mm), and electrical life rating (40,000 cycles versus 6,000 cycles). The TE Connectivity part is suitable for applications where these mechanical and performance variations are acceptable.

Q: Are there compliance or certification differences between these substitutes?

A: The 7105P4HCRE and 3-1825137-7 both meet RoHS3 compliance. The 7105P4HCLE is REACH Unaffected, while both substitute parts are REACH Affected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the significance of the electrical life rating difference?

A: The 7105P4HCLE and 7105P4HCRE are rated for 40,000 electrical cycles, while the TE Connectivity 3-1825137-7 is rated for 6,000 cycles. Select based on the expected operational cycle count for your application. Higher cycle applications require the 40,000-cycle rated components.

Q: Does the actuator length difference affect panel mounting?

A: Panel mounting compatibility is maintained across all three parts due to identical panel cutout dimensions (6.35mm circular) and bushing thread specifications (1/4-40). The actuator length difference affects only the external mechanical profile and user interface feel, not the mounting interface.

Q: Are all three parts available in the same packaging format?

A: The 7105P4HCLE and 7105P4HCRE are available in standard packaging. The TE Connectivity 3-1825137-7 is supplied in bulk packaging. Confirm packaging requirements and minimum order quantities with your supplier.
