Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors are parametrically equivalent TNCA jack female socket connectors with identical electrical specifications (50 ohms, 18 GHz maximum frequency), mechanical mounting features (panel mount bulkhead with threaded fastening), contact materials (beryllium copper with gold plating), and compliance certifications (ROHS3). Direct substitution is valid for RF applications.

Q: What is the difference between PRF04-J-C-EP-190-BS and PRF04-J-C-EP-335A-BS?

A: Both parts are electrically and mechanically equivalent TNCA connectors with identical impedance, frequency rating, termination method, and mounting configuration. The part number suffix variation reflects internal Samtec designation. No functional difference exists for connector selection purposes.

Q: Are all three parts ROHS3 compliant?

A: Yes. PRF04-J-C-EP-190-BS, PRF04-J-C-EP-142-BS, and PRF04-J-C-EP-335A-BS are all ROHS3 compliant and carry EAR99 export classification with HTSUS code 8536.69.4010.

Q: What is the maximum operating frequency for these connectors?

A: All three equivalent parts support RF operation up to 18 GHz with 50-ohm impedance matching.

Q: Can these connectors be used interchangeably in panel mount applications?

A: Yes. All three parts feature identical panel mount specifications with bulkhead front-side nut mounting and threaded fastening, enabling direct interchangeability in PCB and chassis installations.

Q: What termination method is used for these connectors?

A: All three parts use solder contact termination with clamp shield termination, suitable for direct PCB soldering and RF shielding applications.
