Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-1478968-0 is determined by strict equivalence across the following critical parameters: SMA connector style, female socket jack type, 50 Ohm impedance, solder contact and shield termination, panel mount configuration with flange mounting feature, threaded fastening, 18 GHz maximum frequency, single port design, extended insulation features, gold housing and plating, beryllium copper center contact material, PTFE dielectric material, and 500 mating cycles rating.

All identified substitute parts maintain these core electrical and mechanical specifications. Variations exist in body material composition (stainless steel versus brass versus beryllium copper), operating temperature ranges, voltage ratings, and regulatory compliance certifications. These variations do not affect functional interchangeability within the specified parameter envelope.

Engineering Selection Recommendations

All identified substitute parts maintain functional equivalence to the TE Connectivity 1-1478968-0 across core electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

RoHS Compliance: The primary part carries RoHS Compliant status. All substitute parts carry ROHS3 Compliant certification, which represents an updated regulatory standard and is acceptable for applications requiring RoHS compliance.

REACH Regulatory Status: The primary part is REACH Affected. Cinch Connectivity Solutions parts (142-1701-011, 142-1701-031, 142-1701-041, 142-1701-201, 142-1701-336) and Radiall parts (R125464000, R125512000) are REACH Affected. Huber+Suhner parts (23_SMA-50-0-13/111_NE, 23_SMA-50-0-13/111_NH) and Amphenol part (2950-6061) are REACH Unaffected. Selection depends on supply chain REACH compliance requirements.

Body Material Variations: The primary part features stainless steel body construction. Cinch Connectivity Solutions parts use brass body material. Huber+Suhner parts use beryllium copper body material. Amphenol and Radiall parts use stainless steel body material. Body material selection does not affect electrical performance within the specified parameter envelope.

Operating Temperature Range: The primary part does not specify an operating temperature range. Cinch and Radiall parts specify -65°C to 165°C operation. Huber+Suhner parts specify -65°C to 125°C operation. Amphenol part does not specify operating temperature. Selection should align with application thermal requirements.

Voltage Rating: The primary part does not specify voltage rating. Cinch parts specify 335 V. Radiall parts specify 500 V. Huber+Suhner and Amphenol parts do not specify voltage rating. Selection should align with application voltage requirements.

Moisture Sensitivity Level: The primary part carries MSL 1 (Unlimited). Cinch parts carry MSL 1 (Unlimited). Huber+Suhner, Amphenol, and Radiall parts carry Not Applicable MSL rating. Selection depends on storage and handling requirements.

Inventory Availability: Current stock levels range from 845 to 5129 pieces across all substitute parts, providing multiple sourcing options.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 142-1701-031 directly replace the TE Connectivity 1-1478968-0?

A: Yes. Both parts maintain identical SMA connector style, female socket jack type, 50 Ohm impedance, solder termination, panel mount flange configuration, threaded fastening, 18 GHz frequency rating, extended insulation features, gold housing and plating, beryllium copper center contact material, PTFE dielectric material, and 500 mating cycles rating. The primary difference is body material composition (brass versus stainless steel), which does not affect electrical or mechanical interchangeability within the specified parameter envelope.

Q: What is the difference between the Huber+Suhner 23_SMA-50-0-13/111_NE and 23_SMA-50-0-13/111_NH parts?

A: Both Huber+Suhner parts maintain identical electrical and mechanical specifications. The designation difference (NE versus NH) reflects manufacturing or configuration variations not detailed in the provided parameters. Both parts are functionally equivalent to the primary part and to each other.

Q: Are the Radiall R125464000 and R125512000 parts interchangeable?

A: Both Radiall parts maintain identical electrical specifications and are functionally equivalent to the primary part. The primary difference is mounting feature configuration: R125464000 features a 2-hole flange mount, while R125512000 features a square flange mount. Selection depends on panel cutout and fastening hole configuration requirements.

Q: Does body material affect RF performance?

A: Within the specified parameter envelope, body material variations (stainless steel, brass, or beryllium copper) do not affect RF performance. All parts maintain 50 Ohm impedance, 18 GHz frequency rating, and identical dielectric material specifications. Body material selection is driven by mechanical durability, thermal conductivity, and cost considerations rather than electrical performance.

Q: Which substitute part should be selected for applications requiring REACH compliance?

A: For applications requiring REACH Unaffected status, select Huber+Suhner parts (23_SMA-50-0-13/111_NE or 23_SMA-50-0-13/111_NH) or Amphenol part (2950-6061). For applications where REACH Affected status is acceptable, all other substitute parts are available.

Q: What is the significance of the operating temperature range difference between Cinch and Huber+Suhner parts?

A: Cinch Connectivity Solutions parts specify -65°C to 165°C operating temperature. Huber+Suhner parts specify -65°C to 125°C operating temperature. Selection should align with application thermal environment. Applications requiring operation above 125°C should utilize Cinch or Radiall parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part carries RoHS Compliant certification. All substitute parts carry ROHS3 Compliant certification, which represents an updated regulatory standard and satisfies RoHS compliance requirements.

Q: What packaging differences exist among substitute parts?

A: The primary part and most substitute parts are supplied in Bulk packaging. Radiall parts (R125464000 and R125512000) are supplied in Box packaging. Packaging selection does not affect component functionality and is driven by inventory management and handling requirements.
