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 connector plug manufactured by Samtec Inc., designed for RF coaxial cable applications. This male pin connector operates at 50 ohms impedance with a maximum frequency rating of 18 GHz and utilizes solder termination for both center contact and shield. The part is classified as Active product status with ROHS3 compliance and is currently in stock with 933 units available.

Substitute parts are identified when design requirements permit cable length variations or when inventory constraints necessitate alternative part selection. All substitute parts maintain identical electrical and mechanical specifications across critical parameters including impedance, connector style, contact termination method, and frequency rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRF04-P-C-EP-290-SS are determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

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

Material and Construction Criteria:

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

Compliance Criteria:

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

All substitute parts listed maintain 100% alignment with these parameters. The primary differentiator among parts in this group is cable length specification, which is reflected in the part number suffix (290, 142, 190, 200, 335, 335A). Cable length variation does not affect electrical performance, mechanical compatibility, or regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to the PRF04-P-C-EP-290-SS across electrical, mechanical, and material specifications. Selection among these parts is based on the following engineering considerations:

Product Status and Availability: All parts carry Active product status, indicating current manufacturing support and long-term availability. Inventory levels vary across the substitute group, with PRF04-P-C-EP-290-SS maintaining the highest stock level at 933 units.

Regulatory Compliance: All substitute parts maintain identical ROHS3 compliance status and ECCN/HTSUS classifications, ensuring equivalent regulatory treatment in procurement and export scenarios.

Cable Length Specification: The part number suffix indicates cable length variation. Selection should be based on specific cable length requirements for the application. The numerical suffix (142, 190, 200, 290, 335, 335A) corresponds to cable length specifications defined in Samtec documentation.

Packaging Considerations: PRF04-P-C-EP-200-SS and PRF04-P-C-EP-335A-SS are listed with packaging designation as not specified. PRF04-P-C-EP-290-SS, PRF04-P-C-EP-142-SS, PRF04-P-C-EP-190-SS, and PRF04-P-C-EP-335-SS are packaged in Bulk format.

Frequently Asked Questions (FAQ)

Q: Can PRF04-P-C-EP-290-SS be directly replaced with PRF04-P-C-EP-142-SS?

A: Yes, from an electrical and mechanical standpoint. Both parts are parametrically equivalent across impedance, frequency rating, connector style, termination method, and material composition. The primary difference is cable length specification. Substitution is valid when the cable length requirement of the application permits the alternative part number.

Q: What determines whether a part qualifies as a substitute for PRF04-P-C-EP-290-SS?

A: Substitution eligibility is determined by equivalence across six parameter categories: electrical specifications (impedance, frequency, port count), mechanical design (connector style, type, termination methods, mounting configuration), material composition (contact material, body material, plating, dielectric), and regulatory compliance (RoHS status, ECCN, HTSUS classification). All listed substitute parts meet these criteria.

Q: Are there any performance differences between PRF04-P-C-EP-290-SS and its substitutes?

A: No performance differences exist across the specified electrical and mechanical parameters. All parts operate at 50 ohms impedance with 18 GHz maximum frequency rating. Differences in part numbering reflect cable length variations only, which do not affect connector performance characteristics.

Q: Does packaging format affect the suitability of a substitute part?

A: Packaging format does not affect electrical or mechanical compatibility. However, procurement processes may have specific packaging requirements. PRF04-P-C-EP-200-SS and PRF04-P-C-EP-335A-SS have unspecified packaging designations, while other parts in this group are supplied in Bulk packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including PRF04-P-C-EP-290-SS and all substitute options, maintain ROHS3 compliance status. This ensures equivalent regulatory treatment and environmental compliance across the entire substitute group.

Q: How should cable length be determined when selecting among substitute parts?

A: Cable length specification is embedded in the part number suffix. Selection should be based on the specific cable length requirement for the application. Samtec technical documentation provides detailed cable length specifications for each part number variant within the PRF series.
