Engineering Selection Recommendations

The Amphenol RF 031-71052-10RFX is a qualified substitute for the obsolete TE Connectivity 1-1478031-0 based on the following engineering criteria:

Product Status: The substitute part maintains active product status with current manufacturing and availability, eliminating supply chain risk associated with the obsolete original part.

Compliance Certifications: Both parts are RoHS compliant. The substitute achieves ROHS3 compliance, meeting current regulatory requirements. Both parts carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory equivalence.

Electrical and Mechanical Equivalence: All critical parameters for RF coaxial connector substitution are matched, including impedance, termination methods, mounting configuration, and environmental ratings. The substitute part supports the full operating temperature and voltage specifications of the original design.

Frequency Performance: The substitute part is rated to 1 GHz maximum frequency, compared to the original part's 2 GHz rating. Applications operating at frequencies below 1 GHz experience no performance degradation. Applications requiring operation above 1 GHz require frequency performance verification against actual system requirements.

Packaging and Availability: The substitute is supplied in tray packaging with 936 pieces in current stock, providing immediate availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71052-10RFX be used as a direct replacement in existing PCB designs?

A: Yes. The substitute part maintains identical mechanical mounting specifications, through-hole solder termination, and panel mount configuration. PCB layouts and assembly processes require no modification.

Q: What is the significance of the frequency rating difference between the original and substitute parts?

A: The original part is rated to 2 GHz maximum frequency, while the substitute is rated to 1 GHz. For applications operating below 1 GHz, this difference has no impact on performance. Applications requiring operation above 1 GHz must verify that the 1 GHz rating of the substitute part meets system frequency requirements.

Q: Are there differences in contact materials between the two parts?

A: Yes. The original part uses brass center contacts, while the substitute uses phosphor bronze. Both materials are standard for BNC connectors and maintain the specified 75 Ohm impedance and electrical performance characteristics.

Q: What is included with the Amphenol RF substitute part?

A: The substitute part includes three components: one connector, one lockwasher, and one nut. The original part specification does not detail included components.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant. The substitute achieves ROHS3 compliance, representing the current regulatory standard. Both parts carry identical ECCN and HTSUS classifications.

Q: What is the difference in dielectric material between the parts?

A: The original part uses polyethylene (PE) dielectric material, while the substitute uses polypropylene (PP). Both materials are standard for BNC connectors and maintain the specified 75 Ohm impedance.

Q: Is the substitute part available in the same packaging as the original?

A: The original part packaging is not specified in the available documentation. The substitute is supplied in tray packaging with 936 pieces currently in stock.
