Frequently Asked Questions (FAQ)

Q: Can PRF01-P-C-EP-120C-SS be used as a direct replacement for PRF01-P-C-EP-290A-SS?

A: Yes. Both connectors share identical electrical specifications (50 Ohms, 18 GHz maximum frequency), mechanical configuration (SMA plug, male pin, free hanging in-line mounting), termination method (solder contact, clamp shield), and material composition (stainless steel body, beryllium copper center contact, gold plating, PTFE dielectric). Direct substitution requires no circuit modification.

Q: What is the difference between PRF01-P-C-EP-290A-SS and PRF01-P-C-EP-290-SS-1?

A: These parts are electrically and mechanically identical. The designation suffix "-1" indicates a variant revision. Both maintain identical performance characteristics, impedance, frequency rating, and material specifications. Selection between them is based on inventory availability and procurement timing.

Q: Does packaging type affect connector performance?

A: Packaging type does not affect electrical or mechanical performance. PRF01-P-C-EP-335A-SS is supplied in Bulk packaging, while other equivalents use standard packaging. Packaging selection is determined by manufacturing process requirements and inventory management practices, not by functional specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, confirming conformance to Restriction of Hazardous Substances regulations. This certification applies uniformly across all equivalent parts.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. All substitute parts maintain identical mechanical dimensions, mounting configuration (free hanging in-line), and fastening type (threaded). No PCB layout modification is required for connector substitution.

Q: What determines the substitution relationship between these parts?

A: Substitution is based on matching all specified parameters: connector style (SMA), connector type (plug, male pin), impedance (50 Ohms), frequency rating (18 GHz maximum), contact termination (solder), shield termination (clamp), mounting type (free hanging in-line), fastening type (threaded), center contact material (beryllium copper), body material (stainless steel), center contact plating (gold), dielectric material (PTFE), housing color (silver), and compliance status (ROHS3 compliant, Active product status).
