Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RF292A2JDFAL are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector style: 2.92mm
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting type: Panel Mount with Flange
• Contact termination: Solder
• Frequency capability: 40 GHz maximum
• Center contact material: Beryllium Copper

Secondary Compatibility Factors:

• Fastening type: Threaded
• Number of ports: 1
• Body material composition (Stainless Steel or Brass with appropriate finish)
• Dielectric material (Polyetherimide or equivalent)
• Operating temperature range capability

The RF292A2JDFAL differs from its primary substitute RF292A4JCCA only in the number of mounting holes (2 holes versus 4 holes). All WITHWAVE PM03FS series parts maintain identical electrical specifications and connector interface standards while offering variations in body material composition and center contact plating options. Shield termination differences (solder versus screw) do not affect electrical performance in the RF domain but may influence mechanical assembly procedures.

Parameter Comparison

Engineering Selection Recommendations

Bulgin RF292A2JDFAL (Primary Part) The RF292A2JDFAL is the specified component with active production status and ROHS3 compliance. This part is suitable for applications requiring a 2-hole flanged panel mount configuration with solder termination for both center contact and shield. The operating temperature range of -40°C to 85°C and 250 V voltage rating define the environmental and electrical constraints for this selection.

Bulgin RF292A4JCCA (Direct Equivalent) The RF292A4JCCA is functionally equivalent to the RF292A2JDFAL with identical electrical specifications and operating parameters. The only mechanical difference is the 4-hole mounting configuration instead of 2 holes. This part is suitable when panel designs require four mounting points for enhanced mechanical stability. Both parts share the same base product number (RF292) and maintain ROHS3 compliance.

WITHWAVE PM03FS Series (Parametric Equivalents) The WITHWAVE PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS060, PM03FS061, PM03FS062, and PM03FS063 connectors are parametric equivalents that maintain the critical 2.92mm connector interface, 50 ohm impedance, and 40 GHz frequency capability. These parts differ in the following aspects:

• Shield termination uses screw mechanism instead of solder
• Operating temperature range extends to -40°C to 135°C, providing wider thermal capability
• Center contact plating is gold-plated across all PM03FS variants
• Body material varies between Stainless Steel (PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS061, PM03FS063) and Brass with Tin/Nickel finish (PM03FS060, PM03FS062)
• Dielectric material is Polyetherimide (PEI) for stainless steel variants; not specified for brass variants

All substitute parts maintain active production status and are available in stock quantities ranging from 769 to 1144 units.

Frequently Asked Questions (FAQ)

Q: Can RF292A4JCCA be used as a direct replacement for RF292A2JDFAL?

A: The RF292A4JCCA is electrically and mechanically compatible with the RF292A2JDFAL. The difference is the number of mounting holes (4 versus 2). Substitution is valid if the panel design accommodates the 4-hole configuration. Both parts maintain identical impedance, frequency response, termination method, and operating specifications.

Q: What is the primary difference between Bulgin and WITHWAVE connector options?

A: The Bulgin RF292 series uses solder shield termination, while the WITHWAVE PM03FS series uses screw shield termination. Electrically, both maintain 50 ohm impedance and 40 GHz frequency capability. The WITHWAVE parts offer extended operating temperature range (-40°C to 135°C versus -40°C to 85°C) and gold-plated center contacts. Shield termination method affects assembly procedures but not RF performance.

Q: Are the WITHWAVE PM03FS parts interchangeable with each other?

A: The PM03FS056 through PM03FS063 parts are electrically interchangeable as they all maintain the 2.92mm connector interface, 50 ohm impedance, and 40 GHz frequency capability. Variations exist in body material (Stainless Steel versus Brass) and dielectric material specifications. Selection between variants depends on environmental requirements and mechanical design constraints rather than RF performance.

Q: What is the significance of the extended operating temperature range in WITHWAVE parts?

A: The WITHWAVE PM03FS series operates from -40°C to 135°C, compared to -40°C to 85°C for the Bulgin RF292A2JDFAL. This extended range accommodates applications requiring higher temperature operation. Selection should be based on the actual thermal environment of the application.

Q: Does the gold plating on WITHWAVE center contacts affect compatibility?

A: Gold plating on the center contact improves corrosion resistance and contact reliability but does not affect electrical compatibility. The RF292A2JDFAL and WITHWAVE parts maintain identical impedance and frequency characteristics regardless of plating differences.

Q: What mounting hole configuration should be selected?

A: The RF292A2JDFAL features 2 mounting holes, while the RF292A4JCCA features 4 mounting holes. Selection depends on the panel design and mechanical stability requirements. Both configurations maintain identical RF performance and electrical specifications.

Q: Are all listed parts ROHS3 compliant?

A: The Bulgin RF292A2JDFAL and RF292A4JCCA are explicitly ROHS3 compliant. Compliance status for WITHWAVE PM03FS series parts is not specified in the provided data.

Q: What is the significance of shield termination method (solder versus screw)?

A: Shield termination method affects assembly procedures and mechanical connection approach but does not impact RF electrical performance. Solder termination (Bulgin parts) requires soldering during assembly, while screw termination (WITHWAVE parts) uses mechanical fastening. Selection depends on manufacturing process and assembly capabilities.
