Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RF292A2JDFC are grouped based on strict equivalence of the following critical parameters: 2.92mm connector style, jack female socket configuration, 50 ohm impedance, compression contact termination, screw shield termination, panel mount with flange, threaded fastening, 40 GHz maximum frequency, single port, 250 V voltage rating, and 500 mating cycles. All substitute parts maintain these core electrical and mechanical specifications. Variations in operating temperature range, center contact plating, body material, dielectric material, and insertion loss are noted but do not disqualify substitution when the primary functional parameters align. All substitute parts are Active in product status and ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the RF292A2JDFC. The Bulgin variants RF292A2JEGA and RF292DJB provide direct manufacturer equivalents with identical electrical specifications; RF292DJB extends the operating temperature range to -55°C ~ 125°C for applications requiring enhanced thermal performance. The Rosenberger 02K721-40MS3 and 02K722-40MS3 connectors deliver equivalent RF performance with PTFE dielectric material and gold-plated center contacts, suitable for applications prioritizing low insertion loss and high-frequency stability. The Taoglas PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS variants feature brass bodies with gold finish and maintain the same 40 GHz frequency capability with 0.38 dB insertion loss specification; these are appropriate for PCB-mounted applications with restricted operating temperature ranges. The WITHWAVE VC03FS001 and VC03FS002 connectors provide vertical launch configurations with stainless steel construction and gold-plated contacts; limited specification data requires verification of operating temperature and mating cycle performance for critical applications.

Frequently Asked Questions (FAQ)

Q: Can RF292A2JEGA be used as a direct replacement for RF292A2JDFC?

A: Yes. Both parts are manufactured by Bulgin and share identical electrical and mechanical specifications: 2.92mm connector style, jack female socket configuration, 50 ohm impedance, compression termination, 40 GHz frequency rating, 250 V voltage rating, and 500 mating cycles. Operating temperature ranges are identical at -40°C ~ 85°C. Both are ROHS3 compliant with Polyetherimide dielectric and beryllium copper center contacts.

Q: What is the difference between RF292DJB and RF292A2JDFC?

A: RF292DJB extends the operating temperature range to -55°C ~ 125°C compared to RF292A2JDFC at -40°C ~ 85°C. All other electrical and mechanical parameters are identical. RF292DJB is suitable for applications requiring wider thermal operating conditions.

Q: Are Rosenberger 02K721-40MS3 and 02K722-40MS3 interchangeable with RF292A2JDFC?

A: Both Rosenberger connectors meet the core electrical specifications: 2.92mm style, jack female socket, 50 ohm impedance, compression termination, 40 GHz frequency, and 250 V rating. Differences include PTFE dielectric material (versus Polyetherimide), gold-plated center contacts, and operating temperature range of 0°C ~ 85°C. The 02K721-40MS3 specifies 0.25 dB insertion loss. These variants are suitable for applications where PTFE dielectric performance is preferred.

Q: What are the key differences between Taoglas and Bulgin 2.92mm connectors?

A: Taoglas variants (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) feature brass bodies with gold finish and gold-plated center contacts, with 0.38 dB insertion loss specification. Operating temperature is restricted to -55°C ~ 50°C. Bulgin variants use stainless steel bodies and maintain -40°C ~ 85°C or -55°C ~ 125°C operating ranges. Both maintain 40 GHz frequency capability and 50 ohm impedance.

Q: Can WITHWAVE VC03FS001 and VC03FS002 be used without additional verification?

A: WITHWAVE connectors meet the primary electrical specifications (2.92mm, jack female socket, 50 ohm, compression termination, 40 GHz). However, operating temperature range and mating cycle specifications are not provided in available data. Verification of these parameters against application requirements is necessary before selection.

Q: What mounting configurations are available among the substitute parts?

A: All substitute parts are panel mount connectors with flange mounting features and threaded fastening. The primary distinction is between vertical launch configurations (VC03FS001, VC03FS002) and PCB end-launch variants (Taoglas PCB.292FST and VMPCB.292FST series). Mounting hole count varies between 2-hole and 4-hole configurations in the Taoglas product line.

Q: Are all substitute parts ROHS3 compliant?

A: Bulgin (RF292A2JDFC, RF292A2JEGA, RF292DJB), Rosenberger (02K721-40MS3, 02K722-40MS3), and Taoglas (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) variants are confirmed ROHS3 compliant. WITHWAVE VC03FS001 and VC03FS002 do not specify RoHS status in available documentation.

Q: What is the significance of insertion loss specifications?

A: Rosenberger 02K721-40MS3 specifies 0.25 dB insertion loss, and Taoglas variants specify 0.38 dB insertion loss. RF292A2JDFC does not provide insertion loss data. For applications with strict signal integrity requirements at 40 GHz, insertion loss specifications should be evaluated against system performance budgets.
