Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to PRF04-P-C-EP-142-SS based on electrical and mechanical specifications. Selection among equivalent parts should be based on the following factors:

Product Status: All parts maintain Active product status with Samtec Inc., ensuring continued availability and support.

Compliance Certification: All substitute parts carry identical ROHS3 compliance and EAR99 ECCN classification, meeting regulatory requirements for the same applications.

Inventory Availability: PRF04-P-C-EP-290-SS (933 Pcs) and PRF04-P-C-EP-142-SS (931 Pcs) offer the highest stock levels. PRF04-P-C-EP-200-SS (688 Pcs) offers the lowest availability.

Cable Length Variation: Part number suffixes (142, 190, 200, 290, 335, 335A) indicate cable length or connector length differences. Selection should align with specific cable routing and assembly requirements.

Packaging Consideration: PRF04-P-C-EP-200-SS and PRF04-P-C-EP-335A-SS are supplied without specified packaging designation, while other parts are supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can PRF04-P-C-EP-190-SS be used as a direct replacement for PRF04-P-C-EP-142-SS?

A: Yes. Both connectors share identical electrical specifications (50 Ohm impedance, 18 GHz maximum frequency), mechanical configuration (TNCA plug, male pin, solder termination, free-hanging mount), and material composition (beryllium copper center contact, stainless steel body, gold plating, PTFE dielectric). The part number suffix indicates cable length variation only.

Q: What determines the part number suffix in the PRF04-P-C-EP series?

A: The numeric suffix (142, 190, 200, 290, 335, 335A) represents cable length or connector length specifications. All suffixes within this group maintain identical electrical and core mechanical parameters.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification identical to PRF04-P-C-EP-142-SS.

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

A: Yes. All listed parts are rated for frequencies up to 18 GHz with 50 Ohm impedance matching, making them electrically interchangeable for RF coaxial cable applications within this frequency range.

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

A: Both parts are electrically and mechanically equivalent. The difference is in packaging designation: PRF04-P-C-EP-335-SS is supplied in Bulk packaging, while PRF04-P-C-EP-335A-SS packaging is not specified in the provided data.

Q: Are substitute parts available from manufacturers other than Samtec Inc.?
