Amphenol RF 031-5684 RP-TNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 031-5684 is an RP-TNC connector jack with male pin configuration, designed for 50-ohm coaxial cable termination in RF applications. This free-hanging, in-line crimp connector operates at frequencies up to 11 GHz and is compatible with Belden 9913, 9914, and LMR-400 cable groups. The part maintains active product status and is ROHS3 compliant with REACH compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, enabling direct functional replacement in circuit designs and cable assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 031-5684 are identified through parametric equivalence across critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

Electrical Parameters:

• Connector style (RP-TNC)
• Connector type (Jack, Male Pin)
• Impedance (50 Ohms)
• Frequency maximum (11 GHz)
• Voltage rating (500 V)
• Insertion loss (0.18 dB)

Mechanical Parameters:

• Contact termination method (Crimp)
• Shield termination method (Crimp)
• Mounting type (Free Hanging/In-Line)
• Fastening type (Threaded)
• Operating temperature range (-65°C to 165°C)
• Mating cycles (500)

Material and Compliance Parameters:

• Center contact material (Brass)
• Body material (Brass)
• Body finish (Nickel)
• Center contact plating (Gold)
• Dielectric material (PTFE)
• RoHS status (ROHS3 Compliant)
• REACH status (REACH Affected)

Parts meeting all these criteria are classified as parametric equivalents and direct functional substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 031-5684 and 122392RP maintain active product status and are fully compliant with ROHS3 and REACH regulations. The parts are electrically and mechanically equivalent across all critical RF performance parameters, including impedance, frequency response, insertion loss, and operating temperature range.

The primary distinction between these parts is packaging configuration and included accessories. The 031-5684 is supplied with four components including a heat shrink element, while the 122392RP is supplied in bulk packaging with three components excluding the heat shrink. Both parts are suitable for direct substitution in RP-TNC jack applications requiring 50-ohm impedance and crimp termination on compatible cable groups.

Selection between these parts should be based on packaging requirements, inventory availability, and whether the included heat shrink component is necessary for the specific application assembly process.
