Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1337482-0 is determined by strict equivalence across the following critical parameters: SMB connector style, jack male pin configuration, 50 ohms impedance, solder contact and shield termination, through-hole mounting, snap-on fastening, 4 GHz maximum frequency, -65°C to 165°C operating temperature range, 500 mating cycles, PTFE dielectric material, and gold body finish with gold center contact plating.

All identified substitute parts maintain these core electrical and mechanical specifications. Substitute parts are grouped into two categories: parametric equivalents from alternative manufacturers (Amphenol RF, Cinch Connectivity Solutions, and Radiall USA) that provide direct functional replacement, and active status components that supersede the obsolete original part.

The primary distinction among substitute options relates to center contact material composition (brass versus beryllium copper), voltage rating specifications where provided, insertion loss characteristics, and RoHS compliance certification status. These secondary parameters do not affect fundamental connector compatibility but may influence performance in specific application contexts.

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the TE Connectivity 1-1337482-0 across the critical parameters that define SMB 50-ohm connector functionality. Selection among active alternatives should prioritize product status and compliance certifications.

Primary Recommendation Category: Cinch Connectivity Solutions 131-3701 series parts (131-3701-201, 131-3701-261, 131-3701-271) and Radiall USA 2009-1511 series parts (2009-1511-016, 2009-1511-050) represent the most readily available active alternatives with ROHS3 compliance certification and substantial inventory levels. The Cinch 131-3701-261 variant offers the highest inventory availability at 6307 units.

Secondary Recommendation Category: Amphenol RF 903-415J-51P and 903-NM415J-51P provide active alternatives with ROHS3 compliance. The 903-NM415J-51P variant incorporates beryllium copper contact material and non-magnetic features, which may be advantageous in specific RF applications, though this represents a material composition change from the original brass specification.

Compliance Consideration: All substitute parts carry either RoHS Compliant or ROHS3 Compliant certification status, ensuring regulatory alignment with current electronic component standards. The original TE Connectivity part carries RoHS Compliant status; ROHS3 Compliant alternatives represent enhanced compliance certification.

Voltage Rating Consideration: Cinch Connectivity Solutions parts specify 335 V voltage rating compared to the original 250 V specification, providing increased voltage margin without affecting connector compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 903-NM415J-51P substitute for the TE Connectivity 1-1337482-0 despite the beryllium copper contact material difference?

A: Yes. The 903-NM415J-51P maintains all critical electrical and mechanical parameters: SMB connector style, jack male pin configuration, 50 ohms impedance, solder termination, through-hole mounting, 4 GHz frequency rating, and identical operating temperature range. The beryllium copper contact material represents a material composition change that does not affect connector compatibility but may provide enhanced electrical conductivity and durability characteristics in the specific application context.

Q: What is the difference between the Cinch 131-3701-201, 131-3701-261, and 131-3701-271 variants?

A: All three Cinch variants maintain identical electrical and mechanical specifications for SMB connector functionality. The primary differences are inventory availability levels (201: 2634 units, 261: 6307 units, 271: 5418 units) and RoHS certification status (201 and 261 carry ROHS3 Compliant; 211 carries RoHS Compliant). Selection among these variants should be based on procurement availability and specific compliance requirements.

Q: Are the Radiall USA 2009-1511 series parts interchangeable with each other?

A: The Radiall 2009-1511 series parts (2009-1511-000, 2009-1511-016, 2009-1511-028, 2009-1511-050) maintain identical electrical and mechanical specifications for SMB connector functionality. Differences exist in inventory levels, insertion loss specification availability, and RoHS certification status. Parts 2009-1511-016 and 2009-1511-050 carry ROHS3 Compliant certification; 2009-1511-050 carries RoHS Compliant certification. Selection should be based on procurement availability and compliance requirements.

Q: Does the insertion loss specification difference (0.3 dB versus not specified) affect connector selection?

A: Insertion loss specifications are provided for the original TE Connectivity part (0.3 dB), Amphenol RF 903-NM415J-51P (0.3 dB), Amphenol RF 903-415J-51P (0.3 dB), and Radiall 2009-1511-028 (0.30 dB). Substitute parts without specified insertion loss values do not indicate performance degradation; the specification is simply not provided in the component documentation. All parts maintain the same connector architecture and materials that determine insertion loss characteristics.

Q: What is the significance of the 335 V voltage rating on Cinch parts compared to the original 250 V specification?

A: The Cinch Connectivity Solutions parts specify 335 V voltage rating compared to the original TE Connectivity 250 V specification. This represents an increased voltage margin and does not affect connector compatibility. Selection should be based on application voltage requirements; the higher rating provides additional safety margin in applications operating below 250 V.

Q: Are all substitute parts suitable for through-hole PCB solder termination?

A: Yes. All identified substitute parts maintain through-hole mounting type with solder contact and shield termination, identical to the original TE Connectivity 1-1337482-0. PCB layout and solder process parameters remain unchanged.

Q: What is the practical difference between RoHS Compliant and ROHS3 Compliant certification?

A: ROHS3 Compliant represents enhanced RoHS certification that includes additional restricted substance requirements beyond the original RoHS Compliant standard. Both certifications ensure compliance with electronic component environmental and safety standards. Selection between RoHS Compliant and ROHS3 Compliant alternatives should be based on specific regulatory requirements for the end application.
