Substitute Part Grouping Explanation
Substitution eligibility for the PRF18-P-C-EP-047D-SS-B is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Connector Style: 1.85mm
- Connector Type: Plug, Male Pin
- Impedance: 50 Ohms
- Cable Group: 0.047" Semi Rigid
- Contact Termination: Solder
- Shield Termination: Clamp
- Mounting Type: Free Hanging (In-Line)
- Fastening Type: Threaded
- Frequency - Max: 65 GHz
- Center Contact Material: Beryllium Copper
- Center Contact Plating: Gold
- Body Material: Stainless Steel
- Series: PRF
Substitute parts must maintain identical electrical performance (50 Ohm impedance, 65 GHz maximum frequency) and mechanical compatibility (1.85mm connector interface, 0.047" semi-rigid cable group, threaded fastening). Variations in dielectric material composition or packaging format do not affect functional substitutability when all electrical and mechanical parameters remain constant.

Engineering Selection Recommendations
All three parts—PRF18-P-C-EP-047D-SS-B, PRF18-P-C-EP-047A-SS, and PRF18-P-C-EP-047D-SS—are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance and EAR99 export classification. Selection among these equivalents is based on availability and packaging requirements rather than electrical or mechanical performance differences.
PRF18-P-C-EP-047D-SS-B is the primary specification with 921 units in stock. This part number includes the "-B" suffix designation.
PRF18-P-C-EP-047A-SS provides an alternative with 819 units available. This substitute maintains identical electrical and mechanical specifications with PTFE dielectric material.
PRF18-P-C-EP-047D-SS is available in bulk packaging with 764 units in stock. This part features polyetherimide (PEI) dielectric material instead of PTFE, with MSL rating of 1 (Unlimited) and REACH compliance status noted. The dielectric material difference does not affect RF performance at the specified 65 GHz maximum frequency and 50 Ohm impedance.
All three parts are suitable for direct substitution in applications requiring 1.85mm coaxial connectors with 50 Ohm impedance, solder termination, and semi-rigid 0.047" cable compatibility.
Frequently Asked Questions (FAQ)
Q: Can PRF18-P-C-EP-047A-SS be used as a direct replacement for PRF18-P-C-EP-047D-SS-B?
A: Yes. Both parts share identical electrical specifications (50 Ohm impedance, 65 GHz maximum frequency), mechanical configuration (1.85mm connector, 0.047" semi-rigid cable group, threaded fastening), and material composition (beryllium copper center contact with gold plating, stainless steel body, PTFE dielectric). The parts are functionally equivalent for RF applications.
Q: What is the difference between PRF18-P-C-EP-047D-SS and PRF18-P-C-EP-047D-SS-B?
A: The "-B" suffix in PRF18-P-C-EP-047D-SS-B indicates a specific packaging or configuration variant. Both maintain identical electrical and mechanical parameters. The primary PRF18-P-C-EP-047D-SS is available in bulk packaging format.
Q: Does the dielectric material difference (PTFE vs. PEI) affect substitutability?
A: No. Both polytetrafluoroethylene (PTFE) and polyetherimide (PEI) dielectric materials maintain the required electrical performance at 50 Ohm impedance and 65 GHz maximum frequency. The dielectric material variation does not impact RF performance or mechanical compatibility for this connector specification.
Q: Are all three parts ROHS3 compliant?
A: Yes. PRF18-P-C-EP-047D-SS-B, PRF18-P-C-EP-047A-SS, and PRF18-P-C-EP-047D-SS are all ROHS3 compliant and classified as EAR99 for export purposes.
Q: Which part should be selected based on availability?
A: Selection should be based on current inventory requirements. PRF18-P-C-EP-047D-SS-B has 921 units available, PRF18-P-C-EP-047A-SS has 819 units, and PRF18-P-C-EP-047D-SS has 764 units in stock. All are functionally equivalent for direct substitution.
Q: Are there any operating temperature or mating cycle limitations?
A: Operating temperature and mating cycle specifications are not provided in the technical parameters for these parts. Consult Samtec Inc. datasheets for detailed environmental operating conditions if required for specific applications.
