RF292AJB 2.92mm Coaxial Connector Jack Equivalent & Substitute Parts

Part Overview

The RF292AJB is a 2.92mm coaxial connector jack manufactured by Bulgin, designed for high-frequency RF applications requiring female socket termination. This component operates as a free-hanging, in-line solder connector with 50-ohm impedance and supports frequencies up to 40 GHz. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when identical electrical and mechanical parameters are required for component procurement, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the RF292AJB are identified based on strict parametric equivalence across all electrical and mechanical specifications. The substitution logic is based on the following critical parameters that must remain identical:

Connector style (2.92mm)
Connector type (Jack, Female Socket)
Impedance (50 Ohms)
Contact and shield termination method (Solder)
Mounting configuration (Free Hanging, In-Line, Threaded fastening)
Frequency capability (40 GHz maximum)
Operating temperature range (-65°C ~ 165°C)
Voltage rating (250 V)
Mating cycle rating (500)
Material composition (Beryllium Copper center contact, Stainless Steel body, Polyetherimide dielectric)
Compliance certifications (ROHS3, EAR99, HTSUS 8536.69.4010)
Moisture sensitivity level (MSL 1)

Parts RF292AJA and RF292AJG meet all these criteria and are classified as parametric equivalents. Substitution between these parts does not require design modification or performance re-evaluation.
