APH-NJ-TNCJ Equivalent & Substitute Parts

Part Overview

The APH-NJ-TNCJ is a coaxial adapter connector manufactured by Amphenol RF that converts between N Jack (female socket) and TNC Jack (female socket) interfaces. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz and is designed for straight, free-hanging (in-line) mounting applications.

The APH-NJ-TNCJ carries an obsolete product status. Identification of equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and replacement applications where this adapter is specified in existing designs or installations.
