Amphenol RF 031-6166 TNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 031-6166 is an active TNC connector jack, female socket designed for 50 ohm coaxial applications. This panel mount crimp connector operates across RF frequencies up to 11 GHz and is compatible with standard coaxial cable groups including RG-58 variants, LMR-195, and Belden B7806A. The connector is manufactured with weatherproof construction and ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or design flexibility within the same connector family.

Engineering Selection Recommendations

Both the Amphenol RF 031-6166 and 031-6169 are active products with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on inventory availability and procurement requirements rather than technical performance differences.

The 031-6166 maintains 918 units in current stock inventory. The 031-6169 maintains 739 units in current stock inventory. Both connectors carry ROHS3 compliance and REACH affected status, meeting regulatory requirements for commercial and industrial RF applications.

Both parts are manufactured to identical specifications with phosphor bronze center contacts, gold plating, brass bodies with nickel finish, and PTFE dielectric material. The weatherproof construction and 500 mating cycle rating provide equivalent reliability performance across the specified operating temperature range of -65°C to 165°C.

Frequently Asked Questions (FAQ)

Q: Can the 031-6169 be used as a direct replacement for the 031-6166 in existing designs?

A: Yes. The 031-6169 is electrically and mechanically equivalent to the 031-6166 across all specified parameters including impedance, frequency response, termination methods, mounting configuration, and cable compatibility. Direct substitution is supported without design modification.

Q: Are there any differences in the connector's RF performance between these two part numbers?

A: No. Both connectors specify identical insertion loss (0.18 dB), frequency maximum (11 GHz), and impedance (50 Ohms). RF performance characteristics are equivalent.

Q: What cable types are compatible with both connectors?

A: Both the 031-6166 and 031-6169 are compatible with RG-58, RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, and 9907 coaxial cable groups.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both connectors are ROHS3 compliant, REACH affected, rated for weatherproof operation, and carry MSL 1 (Unlimited) moisture sensitivity level. Operating temperature range is -65°C to 165°C for both parts.
