Substitute Part Grouping Explanation

Substitute parts for the R125462000W are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain the following core specifications: SMA connector style, female socket jack configuration, 50 Ohm impedance, panel mount flange mounting, solder termination for both contact and shield, 18 GHz maximum frequency, 500 mating cycles, and PTFE dielectric material. Substitutes are grouped into two categories:

Parametric Equivalents share all critical electrical and mechanical parameters with the main part, differing only in manufacturer, packaging, or non-functional specifications such as body material composition or compliance certifications.

Similar Parts maintain functional equivalence across RF performance parameters but may differ in voltage rating, operating temperature range, or body material while preserving the core 50 Ohm SMA jack functionality.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements. Selection between the R125462000W and its substitutes depends on specific application constraints:

Radiall USA, Inc. substitutes (9308-1113-001, R125464000, R125512000) provide direct manufacturer equivalence with identical stainless steel body construction and PTFE dielectric material. R125464000 and R125512000 maintain the 500 V voltage rating of the main part, while 9308-1113-001 does not specify voltage rating.

Cinch Connectivity Solutions substitutes (142-1701-201, 142-1701-011, 142-1701-031, 142-1701-041, 142-1701-336) employ brass body material instead of stainless steel and specify 335 V voltage rating, which is lower than the main part's 500 V rating. These parts are suitable for applications where the lower voltage specification is acceptable.

Huber+Suhner substitute (23_SMA-50-0-13/111_NE) features beryllium copper body material and operates within a reduced temperature range of -65°C to 125°C compared to the main part's -65°C to 165°C range. This part is suitable for applications not requiring the extended high-temperature capability.

Amphenol SV Microwave substitute (2950-6061) uses stainless steel body material matching the main part but does not specify operating temperature or voltage rating parameters.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly for the R125462000W?

A: All listed parts share the core SMA jack, female socket, 50 Ohm, panel mount solder configuration. Direct substitution is electrically and mechanically valid. However, application-specific constraints such as voltage rating requirements, operating temperature range, or body material compatibility must be evaluated for your specific circuit design.

Q: What is the difference between Radiall and Cinch substitutes?

A: Radiall substitutes maintain stainless steel body construction and the 500 V voltage rating of the main part. Cinch substitutes use brass body material and specify 335 V voltage rating. Both manufacturers produce functionally equivalent SMA jack connectors for 50 Ohm RF applications up to 18 GHz.

Q: Does the body material affect RF performance?

A: Body material does not affect the core RF electrical performance at the specified 18 GHz maximum frequency. Stainless steel and brass bodies both provide adequate shielding and mechanical stability for SMA connector applications. Material selection is driven by mechanical durability, corrosion resistance, and cost considerations rather than RF characteristics.

Q: Why does the Huber+Suhner part have a lower maximum operating temperature?

A: The 23_SMA-50-0-13/111_NE operates to 125°C maximum compared to the main part's 165°C. This difference reflects the design specifications of the Huber+Suhner connector. Applications requiring operation above 125°C must use the main part or other substitutes with higher temperature ratings.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: Both RoHS and ROHS3 indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. All listed parts meet current regulatory requirements for hazardous substance restriction.

Q: Are there packaging differences between these parts?

A: Yes. The main part R125462000W is supplied in standard packaging. Substitute parts are available in Bulk or Box packaging. Packaging does not affect connector performance but may influence order quantities and handling procedures.

Q: Can I use the 142-1701 series parts in high-voltage applications?

A: The Cinch 142-1701 series parts specify 335 V voltage rating, which is lower than the main part's 500 V rating. Applications requiring 500 V operation should use the main part or Radiall substitutes that maintain the 500 V specification.
