PL75C-305 Equivalent & Substitute Parts

Part Overview

The PL75C-305 is a TRB (Twinaxial/Triaxial) connector plug manufactured by Cinch Connectivity Solutions Trompeter. This male pin connector features crimp termination for both center contact and shield, designed for free-hanging in-line applications with bayonet lock fastening. The part is actively produced and widely used in RF coaxial applications requiring reliable signal transmission up to 500 MHz. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, ensuring functional interchangeability in system designs.

Key Parameters

Substitute Part Grouping Explanation

The PL75C-305 and PL75MC-201 are grouped as parametric equivalents based on the following critical substitution criteria:

Both parts share identical electrical and mechanical specifications: TRB connector style, male pin concentric configuration, crimp termination for center contact and shield, non-constant impedance, free-hanging in-line mounting with bayonet lock fastening, 500 MHz maximum frequency, single port configuration, beryllium copper center contact with gold plating, brass body with nickel finish, -65°C to 165°C operating temperature range, 400 V voltage rating, and 500 mating cycles.

The primary distinction lies in cable group assignment (M17/177-00001 for PL75C-305 versus M17/176-00002 for PL75MC-201) and included accessories. The PL75C-305 includes heat shrink and strain relief components, while PL75MC-201 does not specify included accessories. Both parts maintain active product status and comply with RoHS requirements, though with different compliance versions (RoHS Compliant versus ROHS3 Compliant).

Parameter Comparison

Engineering Selection Recommendations

Both PL75C-305 and PL75MC-201 are active products from the same manufacturer with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Cable group compatibility: Verify that the system design accommodates either M17/177-00001 (PL75C-305) or M17/176-00002 (PL75MC-201) cable specifications.

Included accessories: The PL75C-305 includes heat shrink and strain relief components, while PL75MC-201 does not specify included accessories. Assess whether these components are required for your assembly process or if they will be sourced separately.

Compliance requirements: Both parts meet RoHS requirements. The PL75MC-201 carries ROHS3 Compliant status and REACH Affected designation, which may be relevant for specific regulatory environments or supply chain requirements.

Inventory availability: PL75C-305 has 774 pieces in stock, while PL75MC-201 has 1256 pieces available, which may influence procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can PL75MC-201 be used as a direct replacement for PL75C-305?

A: Yes. Both connectors share identical electrical and mechanical parameters including connector style, termination method, impedance, frequency rating, operating temperature, voltage rating, and mating cycles. The primary differences are cable group assignment and included accessories, not functional performance.

Q: What is the significance of the different cable groups (M17/177-00001 vs M17/176-00002)?

A: Cable group designation specifies the cable specifications with which the connector is designed to interface. Verify that your system design or cable assembly specification references the appropriate cable group for your selected connector variant.

Q: Does the inclusion of heat shrink and strain relief in PL75C-305 affect substitution compatibility?

A: These are assembly aids included with PL75C-305. If PL75MC-201 is selected as a substitute, heat shrink and strain relief components must be sourced separately if required for your assembly process. The absence of these components does not affect electrical or mechanical connector performance.

Q: Are there compliance differences between the two parts?

A: Both parts comply with RoHS requirements and carry EAR99 ECCN classification. PL75MC-201 additionally carries ROHS3 Compliant status and REACH Affected designation. Confirm compliance requirements for your specific application or regulatory jurisdiction.

Q: What is the mating cycle rating and what does it indicate?

A: Both connectors are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated while maintaining specified electrical and mechanical performance. This rating applies to both the PL75C-305 and PL75MC-201.
