Substitute Part Grouping Explanation

Substitute parts for the PRF18-J-C-EP-047-SS are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Mandatory Matching Parameters:

• Connector Style: 1.85mm
• Connector Type: Jack, Female Socket
• Contact Termination: Solder
• Shield Termination: Clamp
• Impedance: 50 Ohms
• 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

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in dielectric material composition or packaging format do not affect functional compatibility within the specified electrical and mechanical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PRF18-J-C-EP-047-SS, PRF18-J-C-EP-047A-SS, and PRF18-J-C-EP-047D-SS—maintain Active product status and ROHS3 compliance, confirming their suitability for current procurement and deployment.

PRF18-J-C-EP-047-SS serves as the primary reference part with established inventory of 861 units.

PRF18-J-C-EP-047A-SS is a direct parametric equivalent with 695 units available. This part matches all electrical and mechanical specifications of the main part.

PRF18-J-C-EP-047D-SS is a direct parametric equivalent with the highest inventory level at 966 units. The dielectric material differs (PEI instead of PTFE); however, both materials satisfy the electrical performance requirements within the specified 65 GHz frequency range and 50 Ohm impedance specification. This part is supplied in Bulk packaging format.

Selection among these three parts may be based on inventory availability, packaging requirements, and supply chain logistics, as all three deliver equivalent electrical and mechanical performance for 1.85mm coaxial connector jack applications.

Frequently Asked Questions (FAQ)

Q: Can PRF18-J-C-EP-047A-SS be used as a direct replacement for PRF18-J-C-EP-047-SS?

A: Yes. PRF18-J-C-EP-047A-SS is a parametric equivalent meeting all electrical and mechanical specifications of PRF18-J-C-EP-047-SS, including connector style, impedance, frequency rating, termination method, and material composition.

Q: What is the difference between PRF18-J-C-EP-047-SS and PRF18-J-C-EP-047D-SS?

A: The primary difference is dielectric material composition. PRF18-J-C-EP-047-SS uses PTFE dielectric, while PRF18-J-C-EP-047D-SS uses PEI dielectric. Both materials support the specified 65 GHz frequency range and 50 Ohm impedance. PRF18-J-C-EP-047D-SS is supplied in Bulk packaging.

Q: Are all three parts RoHS compliant?

A: Yes. PRF18-J-C-EP-047-SS, PRF18-J-C-EP-047A-SS, and PRF18-J-C-EP-047D-SS all carry ROHS3 Compliant certification.

Q: What is the significance of the cable group specification 0.047" Semi Rigid?

A: The 0.047" Semi Rigid cable group designation specifies the outer diameter and mechanical properties of the cable intended for use with these connectors. All three substitute parts are rated for this cable group, ensuring mechanical compatibility.

Q: Can these connectors be used interchangeably in high-frequency RF applications?

A: Yes. All three parts support frequencies up to 65 GHz with 50 Ohm impedance and identical connector geometry, enabling interchangeable use in RF applications within this frequency range.

Q: What is the difference in packaging between these parts?

A: PRF18-J-C-EP-047-SS and PRF18-J-C-EP-047A-SS packaging is not specified in the provided data. PRF18-J-C-EP-047D-SS is supplied in Bulk packaging format.

Q: Are there any operating temperature limitations specified for these connectors?

A: Operating temperature specifications are not provided in the available technical data for any of the three parts.
