Parameter Comparison

Engineering Selection Recommendations

The C&K 7105P3CWWRE is the direct equivalent for the obsolete 7105P3CWWLE. Both components share identical electrical ratings, mechanical specifications, and functional characteristics within the C&K 7000 series.

The 7105P3CWWRE maintains Active product status, ensuring continued availability and supply chain reliability. Both parts carry EAR99 export classification and share the same HTSUS commodity code.

Compliance considerations: The main part carries ROHS3 Compliant status with REACH Unaffected designation, while the substitute carries RoHS Compliant status with REACH Affected designation. These differences reflect regulatory classification updates and do not affect functional equivalence for component selection purposes.

Frequently Asked Questions (FAQ)

Q: Can the 7105P3CWWRE directly replace the 7105P3CWWLE in existing applications?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, mounting dimensions, and termination style. Panel cutout and bushing thread specifications are identical, enabling direct mechanical substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 7105P3CWWLE is classified as Obsolete, indicating discontinued production. The 7105P3CWWRE maintains Active status, ensuring ongoing manufacturing and supply availability. This makes the 7105P3CWWRE the appropriate selection for new designs and ongoing procurement.

Q: Are there differences in compliance certifications between these parts?

A: Both parts carry EAR99 export classification and identical HTSUS codes. The RoHS and REACH designations differ due to regulatory classification updates, but these do not affect functional equivalence or component selection for standard applications.

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

A: Substitution is determined by equivalence in circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (Panel Mount), actuator specifications, termination style (Wire Wrap), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), ingress protection (IP67), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles).

Q: Is the wire wrap termination compatible with existing PCB layouts designed for the 7105P3CWWLE?

A: Yes. Both components use identical wire wrap termination, ensuring compatibility with existing circuit board designs and wiring harnesses.
