Amphenol RF 083-886 UHF Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 083-886 is an active UHF connector plug designed for coaxial cable termination in RF applications. This male pin connector features solder termination for both center contact and shield, with non-constant impedance characteristics suitable for RG-series cable groups including RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393. The connector operates at frequencies up to 300 MHz with a 500 V voltage rating and supports 500 mating cycles. Identification of equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain compatibility across manufacturing batches and procurement sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 083-886 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: UHF
• Connector Type: Plug, Male Pin
• Contact Termination: Solder
• Shield Termination: Solder
• Impedance: Non-Constant
• Mounting Type: Free Hanging (In-Line)
• Cable Group Compatibility: RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393
• Fastening Type: Threaded
• Frequency - Max: 300 MHz
• Voltage Rating: 500 V
• Mating Cycles: 500
• Dielectric Material: PTFE
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Affected

The substitute part 083-886-2050 maintains full parametric equivalence across all mandatory parameters. Variations in body finish (Silver versus Nickel) and operating temperature specification do not affect functional substitutability for the defined cable groups and frequency range.

Parameter Comparison

Engineering Selection Recommendations

Both the 083-886 and 083-886-2050 are active products from Amphenol RF with full ROHS3 compliance and REACH affected status. Selection between these parts is based on the following criteria:

Primary Selection Factors:

• Both parts maintain identical electrical and mechanical specifications for UHF connector plug applications
• Both support the complete RG-series cable group range and operate within the 300 MHz frequency specification
• Both achieve 500 V voltage rating and 500 mating cycle durability
• Both employ PTFE dielectric material and solder termination methods

Differentiation Factors:

• Body finish differs: 083-886 features Nickel finish; 083-886-2050 features Silver finish
• Operating temperature specification: 083-886-2050 provides explicit temperature range (-65°C ~ 165°C); 083-886 does not specify operating temperature limits

Selection should be based on environmental exposure requirements and corrosion resistance needs. Silver finish provides superior electrical conductivity; Nickel finish provides enhanced corrosion resistance in harsh environments. Both finishes are compatible with the specified cable groups and frequency range.

Frequently Asked Questions (FAQ)

Q: Can the 083-886-2050 directly replace the 083-886 in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications including connector style, termination method, impedance, cable compatibility, frequency rating, and voltage rating. The parts are functionally interchangeable for UHF coaxial connector applications.

Q: What is the significance of the body finish difference between these parts?

A: The 083-886 uses Nickel finish for enhanced corrosion resistance in harsh or humid environments.
