PL74-47 TRB Coaxial Connector Plug - Equivalent & Substitute Parts

Part Overview

The PL74-47 is an active TRB (Twinaxial/Triaxial) connector plug manufactured by Cinch Connectivity Solutions Trompeter. This male pin connector features solder termination and wrench clamp shield termination, designed for RF applications requiring bayonet lock fastening. The part operates across a wide temperature range (-65°C to 165°C) and supports frequencies up to 500 MHz. Finding equivalent or substitute parts is necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific packaging requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The PL74-47 and PL74-47BR are parametric equivalents within the same product series (Series 70). Substitution between these parts is valid based on the following criteria:

Both parts share identical specifications across all critical parameters: TRB connector style, male pin (concentric) configuration, solder contact termination, wrench clamp shield termination, non-constant impedance, free hanging in-line mounting, bayonet lock fastening, 500 MHz maximum frequency, -65°C to 165°C operating temperature range, 400 V voltage rating, 500 mating cycles, beryllium copper center contact material, brass body with nickel finish, and gold center contact plating.

The primary distinction is packaging: PL74-47BR includes additional components (2 pcs - 1 Connector, 1 Strain Relief) compared to the standard PL74-47 bulk packaging. Both maintain ROHS3 compliance, REACH affected status, and identical electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both PL74-47 and PL74-47BR are active products with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and application needs:

Select PL74-47 for standard bulk connector applications where strain relief is sourced separately or not required.

Select PL74-47BR when integrated strain relief packaging is specified or preferred for assembly efficiency.

Both parts maintain full ROHS3 compliance and REACH affected status, ensuring regulatory alignment for current and future applications. Current inventory levels support both options: PL74-47 (977 pcs) and PL74-47BR (840 pcs).

Frequently Asked Questions (FAQ)

Q: Are PL74-47 and PL74-47BR electrically and mechanically interchangeable?

A: Yes. Both parts are parametric equivalents with identical connector style, pin configuration, termination methods, impedance characteristics, frequency rating, temperature range, voltage rating, and material specifications. They perform identically in RF applications up to 500 MHz.

Q: What is the primary difference between PL74-47 and PL74-47BR?

A: The PL74-47BR includes integrated strain relief packaging (1 connector + 1 strain relief component), while PL74-47 is supplied as a bulk connector only. The core connector component is identical.

Q: Can I use PL74-47BR as a direct replacement for PL74-47 in existing designs?

A: Yes, the connector itself is identical. The additional strain relief in PL74-47BR does not affect electrical or mechanical compatibility. Verify that the strain relief does not create physical interference in your specific application layout.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PL74-47 and PL74-47BR are ROHS3 compliant and REACH affected, with identical regulatory status.

Q: What cable group is compatible with these connectors?

A: Both parts are compatible with M17/176-00002 cable group specifications.

Q: Are there any differences in operating conditions between these parts?

A: No. Both parts operate across -65°C to 165°C, support 500 mating cycles, and maintain 400 V voltage rating with identical material and plating specifications.
