Equivalent & Substitute Parts Reference for BJ224

Part Overview

The Cinch Connectivity Solutions Trompeter BJ224 is a coaxial RF connector adapter, specifically a BNC jack-to-jack (female to female) panel mount adapter with 50 ohm impedance and bayonet lock fastening. This adapter is designed for bulkhead mounting and is suitable for up to 4 GHz frequency applications. The product status is obsolete, making it necessary to identify equivalent or substitute models to ensure continued support for applications or designs dependent on this form factor, function, and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined based on a direct match of key electrical and mechanical parameters: category, adapter type, conversion type, impedance, connection series (BNC to BNC), gender configuration (female to female), mounting method (panel mount, bulkhead), fastening type (bayonet lock), maximum frequency (4 GHz), plating, body material and finish, and regulatory compliance (RoHS Status, MSL). Only parts that exactly match these defined parameters are considered equivalents for substitution.

Parameter Comparison

Engineering Selection Recommendations

Selection logic is based strictly on part status and regulatory compliance. The BJ224 is marked obsolete, while the 31-220N-RFX is active and meets equivalent RoHS3 compliance and MSL (Moisture Sensitivity Level 1, Unlimited). Both parts share matching electrical and mechanical parameters as defined in the relevant product category.

Frequently Asked Questions (FAQ)

Q1: What makes a coaxial RF adapter an exact substitute in this context?
A1: Components are substitutes when all listed electrical parameters (impedance, frequency, center contact plating), mechanical configurations (series, gender, mounting, fastening, body material/finish), and compliance standards (RoHS, MSL) are identical.

Q2: Can any BNC jack-to-jack adapter replace the BJ224?
A2: Only BNC jack-to-jack adapters meeting the precise parameters specified above, including impedance, frequency range, panel mount bulkhead design, and compliance, qualify as substitutes.

Q3: Does the difference in manufacturer affect substitutability?
A3: As long as every specified parameter and standard is met, substitutability is not restricted by manufacturer.

Q4: Are package contents required to match exactly?
A4: Components that include the same listed accessories (e.g. connector, lockwasher, nut) are considered equivalent for substitution.

Q5: Is continued compliance with ROHS3 required for all substitutes?
A5: Yes, ENvironmental compliance as specified is required for all listed substitutes.
