Parameter Comparison

Engineering Selection Recommendations

HR10A-7P-4PC(73) is the direct substitute for HR10A-7P-4PC. Both parts are electrically and mechanically identical across all functional parameters.

The primary distinction is product status and regulatory compliance. HR10A-7P-4PC is obsolete, while HR10A-7P-4PC(73) is active and ROHS3 compliant. For new designs and ongoing production, HR10A-7P-4PC(73) is the appropriate selection. For legacy system maintenance where the original part number is specified, HR10A-7P-4PC(73) provides full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can HR10A-7P-4PC(73) be used as a direct replacement for HR10A-7P-4PC?

A: Yes. Both parts are identical in electrical and mechanical specifications, including pin count, shell size, contact size, fastening mechanism, and operating temperature range. The primary difference is product status and RoHS compliance.

Q: What is the difference between HR10A-7P-4PC and HR10A-7P-4PC(73)?

A: The parts are functionally equivalent. HR10A-7P-4PC is obsolete and RoHS non-compliant, while HR10A-7P-4PC(73) is active and ROHS3 compliant. Packaging differs: HR10A-7P-4PC(73) is supplied in bulk.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The keyed orientation, push-pull fastening, and all mechanical dimensions are identical. Mating connectors and contact pins designed for HR10A-7P-4PC are fully compatible with HR10A-7P-4PC(73).

Q: What does the "(73)" designation indicate?

A: The "(73)" suffix indicates a packaging or variant designation within the HR10A-7P-4PC product line. It does not affect electrical or mechanical performance.

Q: Is HR10A-7P-4PC(73) suitable for applications requiring RoHS compliance?

A: Yes. HR10A-7P-4PC(73) is ROHS3 compliant, making it suitable for applications with RoHS requirements. The original HR10A-7P-4PC is not RoHS compliant.
