Amphenol RF 83-58FCP UHF Coaxial Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 83-58FCP is an active UHF connector plug designed for RF coaxial cable termination. This male pin connector features crimp or solder contact termination and is compatible with RG-58 series cables and equivalent cable types. The connector operates at frequencies up to 300 MHz with a 500 V voltage rating and is housed in a nickel-plated brass body with phenolic dielectric material. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging or plating specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 83-58FCP are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

Connector style (UHF), connector type (plug, male pin), contact termination method (crimp or solder), shield termination (push on), impedance classification (non-constant), mounting type (free hanging in-line), cable group compatibility (RG-58 series and equivalents), fastening type (threaded), maximum frequency (300 MHz), number of ports (1), center contact material (brass), body material (brass), body finish (nickel), dielectric material (phenolic), and voltage rating (500 V).

Substitute parts may differ in packaging configuration, center contact plating material, or inventory availability, provided all electrical and mechanical parameters remain identical. The base product number 83-58 remains constant across all equivalent variants.

Parameter Comparison

Engineering Selection Recommendations

Both the 83-58FCP and 83-58FCP-RFX are active products manufactured by Amphenol RF and maintain full RoHS compliance with MSL 1 rating. The parts are electrically and mechanically equivalent across all critical parameters including connector style, type, termination methods, impedance, frequency rating, and voltage specifications.

The primary differences between these parts are packaging configuration and center contact plating material. The 83-58FCP features silver plating on the center contact and standard packaging, while the 83-58FCP-RFX features gold plating on the center contact and bulk packaging. Both configurations support identical cable groups and maintain the same electrical performance characteristics.

Selection between these equivalent parts should be based on specific application requirements regarding packaging volume, contact plating preference, and inventory availability. Both parts are suitable for direct substitution in applications requiring UHF male plug connectors for RG-58 series coaxial cables operating at frequencies up to 300 MHz.

Frequently Asked Questions (FAQ)

Q: Are the 83-58FCP and 83-58FCP-RFX fully interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector style, type, termination methods, impedance, frequency rating, voltage rating, and cable compatibility. The parts differ only in center contact plating material (silver versus gold) and packaging configuration (standard versus bulk).

Q: What is the significance of the center contact plating difference?

A: The 83-58FCP uses silver plating while the 83-58FCP-RFX uses gold plating on the center contact. Both materials provide adequate electrical conductivity and corrosion resistance for the specified operating conditions. The choice between silver and gold plating depends on application-specific requirements for contact resistance, environmental exposure, and mating cycle expectations.

Q: Can these connectors be used with different cable types?

A: Both parts are compatible with the same cable group: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. Cable compatibility is identical between the two part numbers.

Q: What is the maximum operating frequency for these connectors?

A: Both the 83-58FCP and 83-58FCP-RFX are rated for a maximum frequency of 300 MHz. This specification is identical across both part numbers.

Q: What packaging options are available?

A: The 83-58FCP is supplied in standard packaging, while the 83-58FCP-RFX is supplied in bulk packaging. Packaging selection should be based on order quantity requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes. Both the 83-58FCP and 83-58FCP-RFX are RoHS compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What termination methods are supported?

A: Both parts support crimp or solder contact termination, providing flexibility in assembly processes. The shield termination is push-on for both variants.
