PL75-47 TRB Coaxial Connector Plug - Equivalent & Substitute Parts

Part Overview

The PL75-47 is a TRB (Twinaxial/Triaxial) connector plug manufactured by Cinch Connectivity Solutions Trompeter. This male pin connector features solder termination and is designed for free-hanging, in-line applications. The connector operates at frequencies up to 500 MHz with a bayonet lock fastening mechanism and is rated for 400 V operation across an extended temperature range of -65°C to 165°C. The part maintains Active product status and is ROHS3 compliant with REACH compliance. Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and connector interface standards.

Substitute Part Grouping Explanation

Substitute parts for the PL75-47 are identified through parametric equivalence. The substitution logic is based on matching the following critical parameters: connector style (TRB, Twinaxial/Triaxial), connector type (Plug, Male Pin Concentric), contact termination method (Solder), shield termination (Wrench Clamp), frequency rating (500 MHz maximum), voltage rating (400 V), operating temperature range (-65°C to 165°C), fastening mechanism (Bayonet Lock), mounting configuration (Free Hanging In-Line), and material specifications (Beryllium Copper center contact, Brass body with Nickel finish, Gold plating).

The identified substitute part PL75-47BR maintains all critical electrical and mechanical parameters identical to the main part PL75-47. Both parts share the same base product number (PL75), series designation (70), cable group compatibility (M17/176-00002), and regulatory compliance status (ROHS3, REACH Affected). The primary distinction is packaging configuration: PL75-47BR includes additional components (2 pcs - 1 Connector, 1 Strain Relief) compared to the standard PL75-47 offering.

Engineering Selection Recommendations

Both PL75-47 and PL75-47BR are Active products from Cinch Connectivity Solutions Trompeter with identical electrical and mechanical specifications. Selection between these parts depends on application requirements for strain relief components. The PL75-47BR includes a strain relief assembly, making it suitable for applications requiring cable protection and stress relief at the connector interface. The standard PL75-47 is appropriate for applications where strain relief is managed through alternative means or is not required.

Both parts maintain ROHS3 compliance and REACH compliance status, ensuring regulatory conformance for industrial and commercial applications. Inventory availability is confirmed for both variants, with 1426 units of PL75-47 and 1517 units of PL75-47BR in stock.

Frequently Asked Questions (FAQ)

Q: Are PL75-47 and PL75-47BR electrically and mechanically interchangeable?

A: Yes. Both parts share identical electrical specifications (500 MHz frequency rating, 400 V voltage rating), mechanical interface (TRB connector style, Bayonet Lock fastening), and material composition (Beryllium Copper center contact, Brass body with Nickel finish, Gold plating). The difference is packaging configuration only.

Q: What is the primary difference between PL75-47 and PL75-47BR?

A: The PL75-47BR includes a strain relief component as part of the package, while the PL75-47 is supplied without strain relief. Both connectors are functionally identical.

Q: Can I use PL75-47BR as a direct replacement for PL75-47?

A: Yes. The PL75-47BR can be used as a direct replacement for PL75-47 in any application. The included strain relief provides additional cable protection and may improve assembly reliability in applications subject to mechanical stress.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both PL75-47 and PL75-47BR are ROHS3 compliant and REACH compliant, meeting current environmental and regulatory requirements for electronic components.

Q: What cable group compatibility do these connectors support?

A: Both parts are compatible with cable group M17/176-00002, ensuring standardized cable interface compatibility.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -65°C to 165°C, supporting extended temperature applications in industrial and aerospace environments.
