BJ74-9 Equivalent & Substitute Parts

Part Overview

The BJ74-9 is a TRB (Twinaxial/Triaxial) connector jack manufactured by Cinch Connectivity Solutions Trompeter. This female socket connector features solder termination, panel mount configuration with bulkhead front-side nut mounting, and bayonet lock fastening. The connector operates at frequencies up to 500 MHz with a voltage rating of 400 V and supports 500 mating cycles. The BJ74-9 is classified as an active product with full RoHS3 compliance and REACH compliance status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series, ensuring functional interchangeability in applications requiring TRB jack connectors with identical performance specifications.

Substitute Part Grouping Explanation

The BJ74-9 has one parametric equivalent substitute: BJ79-9. This substitution is valid based on strict parameter matching across all critical electrical and mechanical specifications. Both connectors maintain identical values for connector style (TRB, Twinaxial/Triaxial), connector type (Jack, Female Socket - Concentric), contact termination (Solder), shield termination (Wrench Clamp), impedance classification (Non-Constant), mounting configuration (Panel Mount with Bulkhead - Front Side Nut), fastening mechanism (Bayonet Lock), frequency rating (500 MHz maximum), voltage rating (400 V), operating temperature range (-65°C ~ 165°C), mating cycle rating (500), and material specifications (Beryllium Copper center contact, Brass body with Nickel finish, Gold center contact plating). Both parts are classified as active products with ROHS3 compliance and REACH compliance status. The substitution is based exclusively on these matching parameters, which define functional and electrical interchangeability within the TRB connector series.

Parameter Comparison

Engineering Selection Recommendations

Both BJ74-9 and BJ79-9 are active products with identical compliance certifications: ROHS3 compliant and REACH affected status. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences. The BJ74-9 currently maintains 1012 pieces in stock, while the BJ79-9 maintains 952 pieces in stock. Both connectors meet all regulatory requirements for deployment in applications requiring TRB jack connectors with the specified electrical and mechanical parameters. Component selection should prioritize inventory availability and lead time requirements for the application timeline.

Frequently Asked Questions (FAQ)

Q: Are BJ74-9 and BJ79-9 electrically interchangeable? A: Yes. Both connectors maintain identical electrical specifications including 500 MHz maximum frequency, 400 V voltage rating, and non-constant impedance classification. They are functionally equivalent for RF applications within these parameters.

Q: Can BJ79-9 be used as a direct replacement for BJ74-9 in existing designs? A: Yes. The BJ79-9 is a parametric equivalent with matching mechanical mounting configuration (panel mount, bulkhead front-side nut), fastening type (bayonet lock), and solder termination. No design modifications are required for substitution.

Q: What are the key parameters that define substitution eligibility? A: Substitution is determined by matching connector style (TRB, Twinaxial/Triaxial), connector type (Jack, Female Socket - Concentric), contact termination (Solder), shield termination (Wrench Clamp), impedance (Non-Constant), mounting type (Panel Mount), mounting feature (Bulkhead - Front Side Nut), fastening type (Bayonet Lock), frequency rating (500 MHz), voltage rating (400 V), operating temperature range (-65°C ~ 165°C), mating cycles (500), and material composition (Beryllium Copper center contact, Brass body with Nickel finish, Gold plating).

Q: Do both parts meet the same compliance standards? A: Yes. Both BJ74-9 and BJ79-9 are ROHS3 compliant and REACH affected. They carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010) and moisture sensitivity level (MSL 1 - Unlimited).

Q: What is the difference between BJ74-9 and BJ79-9? A: The parts are parametrically equivalent. The difference lies in the base product number designation (BJ74 versus BJ79) and current inventory levels. No functional or electrical differences exist between these connectors.

Q: Are there any temperature or environmental limitations for these connectors? A: Both connectors operate across the temperature range of -65°C to 165°C. Moisture sensitivity level is classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
