Amphenol RF 031-6824 TNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 031-6824 is an active TNC connector jack designed for 50-ohm RF applications. This female socket connector features solder contact termination with crimp shield termination, suitable for free-hanging in-line mounting configurations. The connector operates across a frequency range up to 6 GHz and supports the LMR-195 cable group. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when cable group compatibility permits substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the 031-6824 is determined by the following critical parameters that must remain constant across equivalent parts:

Connector Style: TNC (standardized RF connector interface)
Connector Type: Jack, Female Socket (mechanical and electrical interface compatibility)
Impedance: 50 Ohms (RF signal integrity requirement)
Contact Termination: Solder (assembly method compatibility)
Shield Termination: Crimp (assembly method compatibility)
Mounting Type: Free Hanging (In-Line) (physical installation requirement)
Frequency - Max: 6 GHz (operational bandwidth)
Operating Temperature Range: -65°C ~ 165°C (environmental specification)
Mating Cycles: 500 (mechanical durability specification)

The substitute part 031-6828 maintains all critical parameters. The primary difference is the supported cable group: 031-6824 supports LMR-195, while 031-6828 supports LMR-240. Both cable groups are compatible with 50-ohm TNC connectors and operate within the specified frequency and temperature ranges.

Engineering Selection Recommendations

Both the 031-6824 and 031-6828 are active products manufactured by Amphenol RF with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for current applications.

Selection between these parts is determined by cable group compatibility:

031-6824: Select when LMR-195 cable integration is required
031-6828: Select when LMR-240 cable integration is required

Both connectors support identical frequency ranges (up to 6 GHz), impedance (50 Ohms), operating temperatures (-65°C to 165°C), and mating cycle ratings (500 cycles). The connector interface, termination methods, and physical mounting characteristics are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can 031-6828 be used as a direct replacement for 031-6824?

A: The connectors are electrically and mechanically equivalent. Substitution is valid when the application uses LMR-240 cable instead of LMR-195 cable. Both cable groups are compatible with 50-ohm TNC connectors and operate within the same frequency and temperature specifications.

Q: What is the primary difference between these two part numbers?

A: The cable group specification differs. The 031-6824 is designated for LMR-195 cable, while the 031-6828 is designated for LMR-240 cable. All other electrical, mechanical, and environmental parameters are identical.

Q: Are both parts currently available?
