PRF04-P-C-EP-300A-SS TNCA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The PRF04-P-C-EP-300A-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 assembly configurations. The connector operates at frequencies up to 18 GHz and is constructed with stainless steel body, beryllium copper center contact with gold plating, and PTFE dielectric material. Product status is Active with ROHS3 compliance and EAR99 export classification. Equivalent substitute parts are identified based on identical electrical and mechanical parameters within the PRF series, enabling component interchangeability for procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRF04-P-C-EP-300A-SS are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Impedance: 50 Ohms
• Frequency - Max: 18 GHz
• Number of Ports: 1

Mechanical Parameters (Must Match):

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

Material & Construction (Must Match):

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

Compliance (Must Match):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8536.69.4010

All identified substitute parts maintain identical specifications across these parameters. Variations in part numbering (such as cable length designations within the part number suffix) do not affect functional equivalence for connector applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts for PRF04-P-C-EP-300A-SS maintain Active product status with ROHS3 compliance and EAR99 export classification. Selection among equivalent parts is based on inventory availability and packaging requirements:

PRF04-P-C-EP-142-SS: 931 Pcs available, Bulk packaging PRF04-P-C-EP-190-SS: 798 Pcs available, Bulk packaging PRF04-P-C-EP-200-SS: 688 Pcs available, standard packaging PRF04-P-C-EP-290-SS: 933 Pcs available, Bulk packaging PRF04-P-C-EP-335-SS: 859 Pcs available, Bulk packaging PRF04-P-C-EP-335A-SS: 830 Pcs available, standard packaging

All substitute parts are functionally equivalent for RF coaxial connector applications requiring 50 Ohm impedance, solder termination, and operation to 18 GHz. Component selection should be based on procurement lead time, packaging format compatibility with assembly processes, and inventory availability. No electrical or mechanical performance differentiation exists among these parts.

Frequently Asked Questions (FAQ)

Q: What determines if a part is a true substitute for PRF04-P-C-EP-300A-SS?

A: A part qualifies as a substitute when it maintains identical specifications across all electrical parameters (50 Ohm impedance, 18 GHz maximum frequency, single port), mechanical parameters (TNCA connector style, male pin plug, solder contact termination, clamp shield termination, free hanging in-line mounting, threaded fastening), material composition (beryllium copper center contact with gold plating, stainless steel body, PTFE dielectric), and compliance certifications (Active status, ROHS3 compliance, EAR99 classification).

Q: Are there any performance differences between PRF04-P-C-EP-300A-SS and its substitutes?

A: No. All substitute parts listed maintain identical electrical and mechanical specifications. Differences in part numbering reflect cable length or assembly configuration variations that do not affect connector performance or compatibility.

Q: Can I use these substitutes interchangeably in production?

A: Yes. All substitute parts are functionally equivalent for RF applications. Interchangeability is determined by matching connector interface specifications, impedance, frequency rating, and termination method. Assembly processes and cable specifications must remain consistent with original design requirements.

Q: What is the significance of packaging format (Bulk vs. standard)?

A: Packaging format affects procurement and inventory management but does not impact connector electrical or mechanical performance. Bulk packaging typically accommodates higher volume orders, while standard packaging suits lower volume requirements. Selection should align with assembly process requirements and order quantities.

Q: Are all these parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the export classification for these connectors?

A: All parts are classified as EAR99 under export control regulations, with HTSUS code 8536.69.4010 for tariff and trade purposes.
