APH-SMAJ-NJBHD Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-NJBHD is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between SMA Jack (Female Socket) and N Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz and supports panel mount bulkhead installation with threaded fastening.

The APH-SMAJ-NJBHD is classified as Obsolete. Identification of equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and new production applications where this adapter type is specified.
