PL75-29 Equivalent and Substitute Parts

Part Overview

The PL75-29 is an active 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 requiring RF connectivity up to 500 MHz. The connector is essential in applications requiring bayonet-locked, high-frequency coaxial connections with specified impedance characteristics. Substitute parts are identified to provide operational continuity when the primary part is unavailable, while maintaining compatibility with the cable groups TWC-78-1 and TWC-124-1A.

Engineering Selection Recommendations

Both the PL75-29 and PL75-29BR are active products from the same manufacturer with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and delivery requirements. Both parts maintain ROHS3 compliance and REACH affected status, confirming regulatory suitability for restricted substance applications. The PL75-29BR includes additional strain relief components in its standard package, which may provide enhanced cable support in applications requiring extended mechanical durability. Component selection should prioritize availability while confirming cable group compatibility with TWC-78-1 or TWC-124-1A prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can PL75-29BR be used as a direct replacement for PL75-29 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters, including connector style, termination method, frequency rating, impedance characteristics, and mating cycle rating. Direct substitution is valid for applications designed for either connector.

Q: What is the difference between PL75-29 and PL75-29BR?

A: The primary difference is in package configuration. PL75-29BR includes an additional strain relief component (2 pcs - 1 Connector, 1 Strain Relief), while PL75-29 is provided as the connector only. Both connectors are electrically and mechanically equivalent.

Q: Are these connectors compatible with my cable assemblies?

A: Compatibility is confirmed when cable assemblies use cable groups TWC-78-1 or TWC-124-1A. Both the PL75-29 and PL75-29BR are specified for these cable groups and maintain impedance compatibility.

Q: What frequency range do these connectors support?

A: Both connectors support RF applications up to 500 MHz maximum frequency.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both the PL75-29 and PL75-29BR maintain full operational specifications across the temperature range of -65°C to 165°C.

Q: Are these connectors RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH affected, confirming suitability for applications subject to restricted substance regulations.

Q: What termination method do these connectors use?

A: Both connectors use solder contact termination with wrench clamp shield termination. The fastening mechanism is bayonet lock for mating.
