Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors are electrically and mechanically identical TNCA male pin plugs with 50 Ohm impedance, 18 GHz frequency rating, solder termination, and clamp shield termination. The difference is cable length only, which does not affect connector performance or interface compatibility.

Q: What is the primary difference between PRF04-P-C-EP-190-RS and PRF04-P-C-EP-335A-RS?

A: Both parts are functionally equivalent TNCA connectors with identical electrical specifications (50 Ohms, 18 GHz) and mechanical construction. The part number suffix indicates cable length variation. All other parameters—contact material, body material, plating, dielectric, and termination method—are identical.

Q: Are all three substitute parts ROHS3 compliant?

A: Yes. PRF04-P-C-EP-190-RS, PRF04-P-C-EP-142-RS, and PRF04-P-C-EP-335A-RS are all ROHS3 compliant with Active product status.

Q: What termination method is used on these connectors?

A: All three parts use solder contact termination with clamp shield termination. The connector is designed for free hanging (in-line), right angle mounting with threaded fastening.

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

A: Yes. All three parts maintain 50 Ohm impedance and 18 GHz maximum frequency rating. They are interchangeable in RF coaxial cable applications within these specifications.

Q: What materials are used in the connector construction?

A: Center contact is beryllium copper with gold plating. The body is stainless steel. The dielectric material is polytetrafluoroethylene (PTFE). Housing color is silver for all three parts.
