Parameter Comparison

Engineering Selection Recommendations

The Cinch Connectivity Solutions Trompeter UPL220-025 is a direct substitute for the Amphenol RF 031-70236 based on electrical and mechanical parameter equivalence. Both components are active products with identical RoHS3 and REACH compliance status.

Selection Criteria:

The UPL220-025 demonstrates parameter parity across all critical specifications including impedance, termination methods, operating temperature range, voltage rating, and material composition. The substitute component's maximum frequency rating of 4 GHz exceeds the main part's 2 GHz specification, providing additional performance margin for applications within the 2 GHz operational envelope.

Both connectors feature identical body material (brass with nickel finish), center contact plating (gold), and dielectric material (PTFE), ensuring mechanical and electrical compatibility in existing cable assemblies and connector interfaces.

Compliance alignment with RoHS3 and REACH regulations confirms suitability for applications subject to these regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity UPL220-025 be used as a direct replacement for the Amphenol RF 031-70236?

A: Yes. The UPL220-025 meets all mandatory electrical and mechanical parameters required for substitution, including 75-ohm impedance, crimp termination for both center contact and shield, bayonet lock fastening, and identical operating temperature and voltage ratings. Both components are RoHS3 and REACH compliant.

Q: What is the significance of the frequency rating difference between the two parts?

A: The Amphenol RF 031-70236 is rated to 2 GHz maximum frequency, while the Cinch Connectivity UPL220-025 is rated to 4 GHz. For applications operating at or below 2 GHz, both components are functionally equivalent. The higher frequency rating of the substitute does not create incompatibility.

Q: Are the cable compatibility groups interchangeable?

A: The Amphenol RF 031-70236 is specified for cable groups RG-122, 180, 180A, 180B, 195, Belden 1855, and 1865A. The Cinch Connectivity UPL220-025 is specified for cable group 734A. Cable compatibility should be verified against specific application requirements and connector interface specifications.

Q: What is the difference in included components between the two parts?

A: The Amphenol RF 031-70236 includes three pieces: 1 connector, 1 contact, and 1 ferrule. The Cinch Connectivity UPL220-025 includes two pieces: 1 connector and 1 contact. Assembly requirements should be evaluated based on application-specific connector configuration needs.

Q: Are both parts available in the same packaging format?

A: The Amphenol RF 031-70236 packaging is not specified in the provided data. The Cinch Connectivity UPL220-025 is supplied in bulk packaging. Packaging format should be confirmed with supplier specifications for procurement and inventory management purposes.

Q: Do both connectors have identical mating cycle ratings?

A: The Amphenol RF 031-70236 specifies 500 mating cycles. The Cinch Connectivity UPL220-025 mating cycle rating is not provided in the available data. Mating cycle requirements for specific applications should be confirmed with component datasheets.

Q: What is the insertion loss specification for each connector?

A: The Amphenol RF 031-70236 specifies 0.2 dB insertion loss. The Cinch Connectivity UPL220-025 insertion loss specification is not provided in the available data. Signal integrity requirements should be evaluated against application specifications.
