Key Parameters

Substitute Part Grouping Explanation

Substitute parts for PRF04-P-C-EP-190-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
• Connector Style: TNCA
• Connector Type: Plug, Male Pin
• Number of Ports: 1

Mechanical Parameters (Must Match):

• Contact Termination: Solder
• Shield Termination: Clamp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Center Contact Plating: Gold
• Body Material: Stainless Steel
• Housing Color: Silver
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Compliance Parameters (Must Match):

• Manufacturer: Samtec Inc.
• Series: PRF
• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8536.69.4010

All substitute parts listed maintain identical values across these parameters. Variations in part numbers reflect cable length specifications or internal dimensional tolerances that do not affect electrical performance or mechanical compatibility within the TNCA connector family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to PRF04-P-C-EP-190-SS and are suitable for direct substitution in applications requiring TNCA male pin connectors with 50 ohm impedance and 18 GHz maximum frequency operation. Selection among substitute parts may be based on inventory availability and procurement lead time considerations.

All parts are manufactured by Samtec Inc., classified as Active product status, and maintain ROHS3 compliance with EAR99 export classification. The stainless steel body construction with gold-plated beryllium copper contacts and PTFE dielectric ensures consistent electrical performance and environmental durability across the entire substitute group.

Frequently Asked Questions (FAQ)

Q: Can PRF04-P-C-EP-190-SS be directly replaced with PRF04-P-C-EP-142-SS?

A: Yes. Both connectors maintain identical electrical specifications (50 ohms, 18 GHz maximum frequency), mechanical construction (solder contact termination, clamp shield termination, threaded fastening), and material composition (beryllium copper contacts, stainless steel body, PTFE dielectric). The part number suffix variation reflects cable length specification only.

Q: What is the difference between PRF04-P-C-EP-335-SS and PRF04-P-C-EP-335A-SS?

A: Both parts are parametrically equivalent across all electrical and mechanical specifications. The suffix variation (-SS versus -A-SS) does not affect connector performance, impedance, frequency rating, or termination method. Selection between these variants is based on availability and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed, including PRF04-P-C-EP-190-SS, PRF04-P-C-EP-142-SS, PRF04-P-C-EP-200-SS, PRF04-P-C-EP-290-SS, PRF04-P-C-EP-335-SS, and PRF04-P-C-EP-335A-SS, are ROHS3 compliant and carry EAR99 export classification.

Q: Do all substitute parts support the same frequency range?

A: Yes. All substitute parts are rated for maximum frequency of 18 GHz and maintain 50 ohm impedance across the entire frequency range.

Q: What is the packaging difference between these parts?

A: PRF04-P-C-EP-190-SS, PRF04-P-C-EP-142-SS, PRF04-P-C-EP-290-SS, and PRF04-P-C-EP-335-SS are supplied in Bulk packaging. PRF04-P-C-EP-200-SS and PRF04-P-C-EP-335A-SS have packaging information not specified in the provided data. Packaging does not affect connector electrical or mechanical performance.

Q: Can these connectors be used interchangeably in RF applications up to 18 GHz?

A: Yes. All substitute parts maintain identical electrical and mechanical parameters required for RF coaxial cable applications. The solder termination method, clamp shield termination, and threaded fastening are consistent across all parts, enabling direct interchangeability in circuit designs and cable assemblies.
