Engineering Selection Recommendations

The HR10-7R-4SA(73) is the direct active equivalent for the obsolete HR10-7R-4SA. Selection between these parts should be based on the following criteria:

For new designs and production: HR10-7R-4SA(73) is the appropriate choice. This variant is in active production status, offers ROHS3 compliance, and includes UL94 V-0 flammability certification. The contact material upgrade to Beryllium Copper with specified finish thickness (8.00µin) provides enhanced performance characteristics.

For legacy system maintenance: HR10-7R-4SA remains available with 973 units in stock. However, transition to HR10-7R-4SA(73) is recommended due to its active product status and improved compliance posture.

Compliance considerations: Applications subject to RoHS3 or REACH regulations must use HR10-7R-4SA(73). The original HR10-7R-4SA does not meet these requirements.

Frequently Asked Questions (FAQ)

Q: Are HR10-7R-4SA and HR10-7R-4SA(73) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shell size, mounting configuration, fastening type, and keyed orientation. They are designed for the same panel mount, through-hole applications with bulkhead rear-side nut mounting.

Q: Can HR10-7R-4SA(73) be used as a direct replacement in existing assemblies?

A: Yes. The HR10-7R-4SA(73) maintains all functional electrical and mechanical parameters of the original part. The primary differences are material composition, compliance certifications, and packaging format, which do not affect connector functionality in equivalent applications.

Q: What is the difference in contact material between these parts?

A: The original HR10-7R-4SA uses Copper Alloy contacts, while HR10-7R-4SA(73) uses Beryllium Copper contacts with a specified gold finish thickness of 8.00µin. Both materials are suitable for the 2A current rating and 150VAC/200VDC voltage specifications.

Q: Why is HR10-7R-4SA classified as obsolete?

A: The HR10-7R-4SA(73) represents the current production variant of this connector series. Manufacturers typically transition to improved versions with enhanced compliance certifications and material specifications, resulting in the obsolescence designation for the earlier variant.

Q: What packaging formats are available?

A: HR10-7R-4SA is supplied in unspecified packaging, while HR10-7R-4SA(73) is supplied in tray packaging. Tray packaging is standard for active production components and facilitates automated assembly processes.

Q: Are there any electrical performance differences?

A: No. Both connectors maintain identical electrical ratings: 2A current capacity and 150VAC/200VDC voltage rating. Operating temperature range is identical at -25°C to 85°C.

Q: Which part should be specified for new designs?

A: HR10-7R-4SA(73) should be specified for all new designs. This part is in active production, meets current compliance standards (ROHS3), and includes UL94 V-0 flammability certification.
