Substitute Part Grouping Explanation
Substitution eligibility for the PRF18-J-C-EP-047A-SS is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Connector Style: 1.85mm
- Connector Type: Jack, Female Socket
- Impedance: 50 Ohms
- Contact Termination: Solder
- Shield Termination: Clamp
- Mounting Type: Free Hanging (In-Line)
- Cable Group: 0.047" Semi Rigid
- Fastening Type: Threaded
- Frequency - Max: 65 GHz
- Number of Ports: 1
- Center Contact Material: Beryllium Copper
- Body Material: Stainless Steel
- Center Contact Plating: Gold
- RoHS Status: ROHS3 Compliant
Variable Parameters (Non-Critical for Substitution):
- Packaging format
- Dielectric material composition
- Moisture Sensitivity Level (MSL)
The substitute part PRF18-J-C-EP-047D-SS maintains full electrical and mechanical compatibility with the main part across all mandatory parameters. The difference in dielectric material (PTFE versus PEI) and packaging configuration does not affect functional equivalence for standard RF applications within the specified frequency range.

Engineering Selection Recommendations
Both PRF18-J-C-EP-047A-SS and PRF18-J-C-EP-047D-SS are active products manufactured by Samtec Inc. and maintain ROHS3 compliance with EAR99 export classification. Selection between these parts should be based on the following criteria:
PRF18-J-C-EP-047A-SS is appropriate when tape and reel packaging is required for automated assembly processes or when the original specification calls for PTFE dielectric material.
PRF18-J-C-EP-047D-SS is appropriate when bulk packaging is preferred for manual assembly, inventory management, or when PEI dielectric material meets application requirements. This variant offers MSL 1 rating, indicating unlimited shelf life under standard storage conditions.
Both connectors deliver identical electrical performance across the 50 Ohm impedance specification and 65 GHz frequency range. The choice between dielectric materials (PTFE versus PEI) should be determined by specific application environmental conditions and thermal requirements not specified in the provided parameters.
Frequently Asked Questions (FAQ)
Q: Are PRF18-J-C-EP-047A-SS and PRF18-J-C-EP-047D-SS electrically interchangeable?
A: Yes. Both connectors maintain identical electrical specifications including 50 Ohm impedance, 65 GHz maximum frequency, solder termination, and gold-plated beryllium copper center contacts. They are electrically equivalent for RF applications.
Q: What is the difference between these two part numbers?
A: The primary differences are packaging format (tape and reel versus bulk) and dielectric material composition (PTFE versus PEI). Both maintain identical mechanical and electrical performance characteristics.
Q: Can I substitute PRF18-J-C-EP-047D-SS for PRF18-J-C-EP-047A-SS in existing designs?
A: Yes, provided your assembly process accommodates bulk packaging and your application environment is compatible with PEI dielectric material. The connector maintains all critical RF and mechanical specifications.
Q: Does the dielectric material difference affect performance?
A: Both PTFE and PEI are suitable dielectric materials for 50 Ohm RF connectors operating to 65 GHz. Material selection should be based on specific application thermal and environmental requirements.
Q: Are both parts ROHS3 compliant?
A: Yes. Both PRF18-J-C-EP-047A-SS and PRF18-J-C-EP-047D-SS are ROHS3 compliant with EAR99 export classification.
Q: What does MSL 1 rating mean for PRF18-J-C-EP-047D-SS?
A: MSL 1 indicates unlimited shelf life under standard storage conditions. This part does not require special moisture control during storage or handling.
Q: Can these connectors be used interchangeably with other 1.85mm connectors?
A: No. Substitution is limited to parts that maintain identical specifications across all critical parameters including impedance, frequency range, termination type, and cable group. Only PRF18-J-C-EP-047D-SS is qualified as an equivalent substitute for PRF18-J-C-EP-047A-SS.
