Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRF92-J-C-EP-047A-SS is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Connector Style: 2.92mm (mechanical interface standard)
• Connector Type: Jack, Female Socket (mating configuration)
• Impedance: 50 Ohms (signal integrity specification)
• Frequency - Max: 40 GHz (bandwidth capability)

Mechanical Compatibility Requirements:

• Mounting Type: Free Hanging (In-Line)
• Cable Group: 0.047" Semi Rigid
• Fastening Type: Threaded
• Contact Termination: Solder

Material and Environmental Requirements:

• Center Contact Material: Beryllium Copper
• Center Contact Plating: Gold
• Body Material: Stainless Steel
• Shield Termination: Clamp
• RoHS Status: ROHS3 Compliant

The substitute part PRF92-J-C-EP-047D-SS matches all critical electrical and mechanical parameters. The dielectric material differs (PEI versus PTFE), which does not affect functional substitution within the specified frequency and impedance range. Packaging configuration differs (Bulk versus standard packaging) but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both PRF92-J-C-EP-047A-SS and PRF92-J-C-EP-047D-SS are Active status products manufactured by Samtec Inc. and maintain ROHS3 compliance. Selection between these parts is based on the following criteria:

PRF92-J-C-EP-047A-SS is the primary specification when the original part number is required for design documentation, configuration control, or when PTFE dielectric material is explicitly specified for the application.

PRF92-J-C-EP-047D-SS serves as a functional equivalent when supply constraints affect PRF92-J-C-EP-047A-SS availability. The PEI dielectric material maintains electrical performance within the 40 GHz frequency specification and 50 Ohm impedance requirement. The Bulk packaging configuration is suitable for high-volume procurement scenarios. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Both parts share identical electrical specifications, mechanical interfaces, and material compositions for critical contact and shielding elements. The dielectric material difference does not introduce functional incompatibility within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can PRF92-J-C-EP-047D-SS be used as a direct replacement for PRF92-J-C-EP-047A-SS in RF applications?

A: Yes. Both connectors meet identical electrical specifications (50 Ohm impedance, 40 GHz maximum frequency), mechanical compatibility (2.92mm jack, female socket, solder termination, free-hanging in-line mounting), and material requirements (beryllium copper center contact with gold plating, stainless steel body). The dielectric material difference (PEI versus PTFE) does not affect functional performance within the specified frequency and impedance range.

Q: What is the significance of the dielectric material difference between these parts?

A: The PRF92-J-C-EP-047A-SS uses PTFE dielectric material, while PRF92-J-C-EP-047D-SS uses PEI. Both materials are suitable for RF applications at 40 GHz. The selection between them is determined by application-specific requirements not specified in the electrical or mechanical parameters. Both maintain the same impedance and frequency characteristics.

Q: Does packaging configuration affect connector performance?

A: No. The packaging difference (standard versus Bulk) is a procurement and logistics consideration only. It does not affect the electrical performance, mechanical compatibility, or physical dimensions of the connector itself.

Q: Are both parts RoHS compliant?

A: Yes. Both PRF92-J-C-EP-047A-SS and PRF92-J-C-EP-047D-SS are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does MSL 1 (Unlimited) mean for PRF92-J-C-EP-047D-SS?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity constraints. It can be stored and handled without time-limited exposure restrictions or special moisture control measures, simplifying inventory management and supply chain handling.

Q: Are these connectors compatible with 0.047" semi-rigid cable?

A: Yes. Both connectors are specified for 0.047" semi-rigid cable group compatibility. The cable group designation ensures mechanical fit and electrical performance with cables of this diameter specification.

Q: What is the fastening mechanism for these connectors?

A: Both connectors use threaded fastening with clamp-type shield termination, providing secure mechanical connection and consistent RF shielding performance.
