PRF04-P-C-EP-290-SS TNCA Coaxial Connector Equivalent and Substitute Parts

Part Overview

The PRF04-P-C-EP-290-SS is a TNCA coaxial connector plug manufactured by Samtec Inc., designed for RF applications requiring 50 Ohm impedance matching. This male pin connector features solder contact termination and clamp shield termination, suitable for free-hanging in-line cable applications. The connector is ROHS3 compliant and rated for operation up to 18 GHz. Equivalent and substitute parts within the PRF series share identical electrical and mechanical specifications, differing only in cable length designations embedded in the part number suffix. Identifying compatible substitutes ensures design flexibility and supply chain continuity when the primary part number becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts within the PRF04-P-C-EP series maintain identical electrical and mechanical characteristics. Substitution compatibility is determined by the following critical parameters:

Electrical Parameters:

• Impedance: 50 Ohms (all parts)
• Frequency Maximum: 18 GHz (all parts)
• Number of Ports: 1 (all parts)

Mechanical Parameters:

• Connector Style: TNCA (all parts)
• Connector Type: Plug, Male Pin (all parts)
• Contact Termination: Solder (all parts)
• Shield Termination: Clamp (all parts)
• Mounting Type: Free Hanging (In-Line) (all parts)
• Fastening Type: Threaded (all parts)

Material Specifications:

• Center Contact Material: Beryllium Copper (all parts)
• Body Material: Stainless Steel (all parts)
• Center Contact Plating: Gold (all parts)
• Dielectric Material: PTFE (all parts)
• Housing Color: Silver (all parts)

Compliance:

• RoHS Status: ROHS3 Compliant (all parts)
• ECCN: EAR99 (all parts)
• HTSUS: 8536.69.4010 (all parts)

The numeric suffix in each part number (142, 190, 200, 290, 335, 335A) represents cable length designations only and does not affect electrical or mechanical compatibility. All parts are interchangeable for RF circuit applications requiring TNCA male pin connectors with 50 Ohm impedance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products from Samtec Inc. with ROHS3 compliance and EAR99 export classification. Selection among equivalent parts should be based on:

Availability and Inventory: Current stock levels vary across the substitute group. PRF04-P-C-EP-290-SS maintains 933 units in inventory, while PRF04-P-C-EP-200-SS has the lowest availability at 688 units.

Compliance Requirements: All parts meet identical regulatory standards (ROHS3 Compliant, HTSUS 8536.69.4010, ECCN EAR99), ensuring interchangeability in applications subject to these certifications.

Electrical Performance: All parts operate identically at 50 Ohm impedance with 18 GHz maximum frequency rating. No performance degradation occurs when substituting between part numbers.

Physical Configuration: Cable length designation differences (142, 190, 200, 290, 335, 335A) do not affect connector electrical or mechanical interface specifications. Selection should align with specific cable assembly requirements.

Frequently Asked Questions (FAQ)

Q: Are all PRF04-P-C-EP series connectors electrically interchangeable?

A: Yes. All parts in this series maintain identical electrical specifications: 50 Ohm impedance, 18 GHz maximum frequency, single port configuration, and solder contact termination. Electrical performance is equivalent across all substitute part numbers.

Q: What do the numeric suffixes (142, 190, 200, 290, 335, 335A) represent?

A: These suffixes designate cable length specifications for the connector assembly. They do not affect the connector's electrical characteristics, mechanical interface, or compatibility with mating components. Selection should be based on cable length requirements for your specific application.

Q: Can PRF04-P-C-EP-290-SS be replaced with PRF04-P-C-EP-335A-SS in an existing design?

A: Yes, provided the cable length difference is accommodated in the physical layout. Both connectors have identical electrical and mechanical interface specifications, including 50 Ohm impedance, TNCA connector style, male pin configuration, solder termination, and clamp shield termination.

Q: Are packaging differences significant for substitution?

A: Packaging format (Bulk or standard) does not affect connector performance or compatibility. Selection between packaging options depends on procurement and inventory management requirements rather than technical compatibility.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. No compliance differences exist between substitute part numbers.

Q: What is the maximum operating frequency for these connectors?

A: All PRF04-P-C-EP series connectors are rated for operation up to 18 GHz. This specification is consistent across all substitute parts.

Q: Are the center contact materials identical across all substitute parts?

A: Yes. All parts use beryllium copper center contacts with gold plating. Body material is stainless steel with PTFE dielectric in all cases. Material specifications are uniform across the entire substitute group.
