Key Parameters

Substitute Part Grouping Explanation

Substitution of the PRF18-P-C-EP-047A-SS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector style (1.85mm)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Frequency maximum rating (65 GHz)
• Number of ports (1)

Mechanical Parameters:

• Contact termination method (Solder)
• Shield termination method (Clamp)
• Mounting type (Free Hanging In-Line)
• Cable group specification (0.047" Semi Rigid)
• Fastening type (Threaded)

Material & Construction Parameters:

• Center contact material (Beryllium Copper)
• Body material (Stainless Steel)
• Center contact plating (Gold)
• Housing color (Silver)

Compliance Parameters:

• RoHS3 compliance status
• ECCN classification (EAR99)
• HTSUS code (8536.69.4010)

The substitute part PRF18-P-C-EP-047D-SS maintains equivalence across all electrical, mechanical, and material specifications. The primary difference is the dielectric material composition, which does not affect substitutability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both PRF18-P-C-EP-047A-SS and PRF18-P-C-EP-047D-SS are active production parts manufactured by Samtec Inc. with ROHS3 compliance and identical EAR99 export classification. Selection between these parts is based on the following criteria:

PRF18-P-C-EP-047A-SS is the primary specification with PTFE dielectric material and higher current inventory availability (819 units).

PRF18-P-C-EP-047D-SS is the parametric equivalent with PEI dielectric material, lower inventory (764 units), and bulk packaging configuration. This part carries MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Affected status.

Both parts maintain identical electrical performance at 65 GHz maximum frequency and 50 ohms impedance. Selection should be based on packaging requirements, inventory availability, and supply chain lead time considerations. Both parts satisfy ROHS3 compliance requirements for regulated applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including connector style, impedance, frequency rating, contact termination, and mounting configuration. The dielectric material difference (PTFE versus PEI) does not affect substitutability within the defined parameter specifications.

Q: What is the difference between the dielectric materials used in these parts?

A: PRF18-P-C-EP-047A-SS uses Polytetrafluoroethylene (PTFE) dielectric material, while PRF18-P-C-EP-047D-SS uses Polyetherimide (PEI). Both materials are suitable for high-frequency RF applications up to 65 GHz. This material difference is the only technical distinction between the two parts.
