Frequently Asked Questions (FAQ)

Q: Can RF292A2JEGA be used as a direct replacement for RF292A2JCCC?

A: Yes. RF292A2JEGA maintains identical electrical and mechanical parameters including 2.92mm connector style, 50 ohm impedance, 40 GHz frequency capability, panel mount flange configuration, compression contact termination, and screw shield termination. Both parts are ROHS3 compliant with 500 mating cycles and 250 V voltage rating.

Q: What is the primary difference between RF292DJB and RF292A2JCCC?

A: The primary difference is operating temperature range. RF292DJB operates from -55°C to 125°C, while RF292A2JCCC operates from -40°C to 85°C. All other electrical and mechanical parameters remain identical. RF292DJB is suitable for applications requiring extended thermal performance.

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

A: Both Rosenberger parts maintain identical core RF parameters including 2.92mm connector style, 50 ohm impedance, 40 GHz frequency capability, and panel mount configuration. The 02K721-40MS3 specifies 0.25dB insertion loss, while insertion loss for 02K722-40MS3 is not specified. Both feature PTFE dielectric and gold-plated center contacts. Selection depends on insertion loss requirements.

Q: What distinguishes Taoglas PCB.292FST.2H.XS and PCB.292FST.4H.XS?

A: Both parts are electrically and mechanically equivalent with identical 2.92mm connector style, 50 ohm impedance, 40 GHz frequency capability, and 0.38dB insertion loss. The designation difference (2H versus 4H) indicates mounting hole configuration. Selection is based on PCB layout requirements and available mounting hole positions.

Q: Can WITHWAVE VC03FS001 and VC03FS002 be used in temperature-critical applications?

A: Operating temperature specifications are not provided for WITHWAVE parts. These parts are suitable for applications where complete thermal performance data are not required or where operating conditions fall within standard industrial ranges. For temperature-critical applications, Bulgin RF292DJB or Taoglas variants with specified operating temperature ranges are recommended.

Q: What is the significance of body material differences between substitute parts?

A: Body material variations (stainless steel versus brass) do not affect RF performance or impedance characteristics. Stainless steel bodies (Bulgin, Rosenberger, WITHWAVE) provide corrosion resistance and durability. Brass bodies with gold finish (Taoglas) provide enhanced contact reliability and reduced insertion loss. Selection is based on environmental exposure and performance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Bulgin, Rosenberger, and Taoglas parts are ROHS3 compliant. WITHWAVE parts do not specify RoHS status in available data. For applications requiring ROHS3 compliance certification, Bulgin RF292A2JEGA, RF292DJB, Rosenberger 02K721-40MS3, 02K722-40MS3, and Taoglas PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS are qualified.

Q: What is the difference between PCB.292FST variants and VMPCB.292FST.A.XS?

A: PCB.292FST.2H.XS and PCB.292FST.4H.XS are vertical mount connectors with different hole configurations. VMPCB.292FST.A.XS is an end-launch PCB connector variant. All three maintain identical electrical parameters including 2.92mm connector style, 50 ohm impedance, 40 GHz frequency capability, and 0.38dB insertion loss. Selection depends on PCB layout and mounting orientation requirements.

Q: Do insertion loss specifications affect RF292A2JCCC substitution?

A: RF292A2JCCC does not specify insertion loss. Substitute parts with specified insertion loss (Rosenberger 02K721-40MS3 at 0.25dB, Taoglas variants at 0.38dB) are suitable for applications where insertion loss is not a critical parameter. For applications with strict insertion loss requirements, parts with specified values should be selected based on system performance budgets.
