Frequently Asked Questions (FAQ)

Q: Can R125052000 be used as a direct replacement for R125052170?

A: Yes. R125052000 maintains identical electrical specifications (50 ohms, 335 V rating, -65°C to 105°C operating temperature) and mechanical configuration (SMA male plug, solder termination, RG-405 cable compatibility, threaded fastening). Both parts use brass center contact material and stainless steel bodies with gold finish. The primary difference is packaging designation.

Q: What is the difference between Radiall and TE Connectivity substitute parts?

A: Both manufacturers produce functionally equivalent SMA male plug connectors meeting the same electrical and mechanical specifications. Radiall parts (9401-1083-010, R125052000, R125052002W) are available in bulk or box packaging. TE Connectivity parts (1-1478904-0, 1050547-1, 1050548-1) include additional component kits (contact and insulator pieces) in bulk packaging. Selection depends on procurement requirements and assembly needs.

Q: Why do some substitute parts have higher voltage ratings?

A: Part 9401-1083-010 features a 350 V voltage rating compared to the 335 V rating of R125052170. This difference results from the use of beryllium copper center contact material, which provides enhanced electrical properties. The higher voltage rating does not affect compatibility in applications designed for 335 V operation.

Q: What is the significance of the extended operating temperature range in R125052002W and 1-1478904-0?

A: R125052002W and 1-1478904-0 operate across -65°C to 165°C, compared to -65°C to 105°C for R125052170. This extended upper temperature limit accommodates high-temperature applications. Selection depends on the specific thermal requirements of the end application. Both parts maintain identical electrical specifications and mechanical compatibility.

Q: Are TE Connectivity parts with included components compatible with existing assemblies?

A: TE Connectivity parts (1-1478904-0, 1050547-1, 1050548-1) include additional components (contact and insulator pieces). These parts are mechanically and electrically compatible with RG-405 cable and existing SMA connector interfaces. The included components support assembly flexibility. Part 1050769-1 (obsolete) includes fewer components (2 pcs versus 3 pcs) and is not recommended for new applications.

Q: What packaging options are available?

A: R125052170 is supplied in bulk packaging. Substitute parts are available in bulk packaging (9401-1083-010, R125052000, 1-1478904-0, 1050547-1, 1050548-1) or box packaging (R125052002W). Packaging selection does not affect electrical or mechanical performance and depends on procurement and inventory management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts maintain ROHS3 compliance. Part 1050769-1 (obsolete) carries RoHS Compliant status. ROHS3 compliance is maintained across all active alternatives, supporting regulatory requirements for electronic component procurement.

Q: What is the difference between center contact materials (Brass versus Beryllium Copper)?

A: R125052170 uses brass center contact material. Substitute parts 9401-1083-010, 1050547-1, 1050548-1, and 1050769-1 use beryllium copper. Both materials are compatible with the 50 ohm impedance specification and PTFE dielectric. Beryllium copper provides enhanced electrical conductivity and durability in high-cycle applications. Material selection does not affect functional interchangeability for standard RF applications.
