Engineering Selection Recommendations

The PSA.1S.302.CLLC42Z is the recommended substitute for the obsolete PSA.1S.302.CLLC37Z. Both components are manufactured by LEMO within the same 1S series and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status, ensuring availability for new designs and field service requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The cable opening tolerance on the PSA.1S.302.CLLC42Z (0.126" ~ 0.165" / 3.20mm ~ 4.20mm) provides a wider range than the main part (0.126" ~ 0.146" / 3.20mm ~ 3.70mm), accommodating a broader range of cable diameters while maintaining full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PSA.1S.302.CLLC42Z be used as a direct replacement for the PSA.1S.302.CLLC37Z?

A: Yes. Both components share identical connector type, position count, shell size, termination method, fastening type, mounting configuration, and electrical ratings. The substitute part is manufactured by the same supplier and maintains all required certifications.

Q: What is the difference between the cable opening specifications?

A: The PSA.1S.302.CLLC37Z accommodates cables with diameters from 0.126" to 0.146" (3.20mm to 3.70mm). The PSA.1S.302.CLLC42Z accepts cables from 0.126" to 0.165" (3.20mm to 4.20mm). The wider tolerance of the substitute part allows compatibility with a greater range of cable sizes while maintaining the same connector interface.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. Regulatory status is equivalent.

Q: Why is the main part listed as obsolete?

A: The PSA.1S.302.CLLC37Z has been discontinued by LEMO. The PSA.1S.302.CLLC42Z represents the active equivalent within the same product series and should be used for all new applications and ongoing procurement.

Q: Are there any mechanical compatibility concerns?

A: No. Both components feature identical mounting types, mounting features, orientation, shell materials, and finishes. Physical and mechanical interfaces are fully compatible.
