PL74-47BR Equivalent & Substitute Parts

Part Overview

The PL74-47BR is a 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 free-hanging in-line applications. The part is actively produced and ROHS3 compliant, making it suitable for applications requiring reliable RF connectivity up to 500 MHz. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series.

Substitute Part Grouping Explanation

The PL74-47 is identified as a parametric equivalent to the PL74-47BR based on strict alignment of electrical and mechanical specifications. Both parts share identical parameters across all critical substitution criteria:

Connector style, type, and termination method (TRB plug with solder contact and wrench clamp shield)
Mounting configuration (free-hanging in-line with bayonet lock fastening)
Electrical performance envelope (500 MHz maximum frequency, 400 V voltage rating, 500 mating cycles)
Operating temperature range (-65°C ~ 165°C)
Cable group compatibility (M17/176-00002)
Compliance certifications (ROHS3, REACH Affected, EAR99)

The primary distinction between these parts is packaging configuration and included accessories. The PL74-47BR includes strain relief components, while the PL74-47 does not specify included accessories. Both parts are manufactured from identical materials (beryllium copper center contact, brass body with nickel finish, gold plating on center contact) and maintain the same series designation (70).

Engineering Selection Recommendations

Both PL74-47BR and PL74-47 are active production parts with identical compliance certifications (ROHS3, REACH Affected, EAR99). Selection between these parts should be based on application-specific packaging requirements. The PL74-47BR includes integrated strain relief components, which may be beneficial for applications requiring additional mechanical protection at the cable interface. The PL74-47 provides equivalent electrical and mechanical performance without specified accessory inclusions. Both parts maintain full compatibility with M17/176-00002 cable group specifications and support identical operating parameters across frequency, temperature, and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can PL74-47 be used as a direct replacement for PL74-47BR?

A: Yes. Both parts maintain identical electrical and mechanical specifications, including connector style, termination method, frequency response, operating temperature range, and voltage rating. The primary difference is packaging configuration and included accessories.

Q: What is the significance of the strain relief inclusion in PL74-47BR?

A: The PL74-47BR includes strain relief components as part of its package. If strain relief is required for your application, verify that the PL74-47 configuration meets your mechanical assembly requirements before substitution.

Q: Are both parts compatible with M17/176-00002 cable specifications?

A: Yes. Both PL74-47BR and PL74-47 are designated for M17/176-00002 cable group compatibility and maintain identical impedance and frequency characteristics for this cable standard.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH affected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Are there any differences in material composition or plating between these parts?

A: No. Both parts use identical materials: beryllium copper center contacts, brass bodies with nickel finish, and gold plating on center contacts. Material specifications are equivalent across all contact and housing components.

Q: What is the maximum operating frequency for both parts?

A: Both PL74-47BR and PL74-47 support operation up to 500 MHz maximum frequency with non-constant impedance characteristics.
