Substitute Part Grouping Explanation

Substitution eligibility for the RF292A2JDFA is determined by strict equivalence across the following critical parameters: connector style (2.92mm), connector type (jack, female socket), impedance (50 ohms), contact termination (compression), shield termination (screw), mounting type (panel mount), mounting feature (flange), fastening type (threaded), frequency maximum (40 GHz), number of ports (1), center contact material (beryllium copper), voltage rating (250 V), and mating cycles (500). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in body material, center contact plating, dielectric material, operating temperature range, and insertion loss are noted but do not preclude substitution when the critical parameters align. Parts are grouped by manufacturer to facilitate sourcing decisions while maintaining full functional compatibility.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are suitable for direct replacement in applications requiring 2.92mm coaxial connector jacks with 50 ohm impedance and compression contact termination.

Bulgin Substitutes (RF292A2JEGA, RF292DJB): These parts are manufactured by Bulgin, the original equipment manufacturer of the RF292A2JDFA. Both parts are ROHS3 compliant and maintain identical electrical specifications. RF292DJB extends the operating temperature range to -55°C to 125°C, providing enhanced thermal performance for applications requiring wider temperature operation.

Rosenberger Substitutes (02K721-40MS3, 02K722-40MS3): Both Rosenberger parts are ROHS3 compliant and maintain the 40 GHz frequency specification. The 02K721-40MS3 provides measured insertion loss of 0.25dB. Both parts feature gold-plated center contacts and PTFE dielectric material, differing from the PEI dielectric of the main part. Operating temperature range is 0°C to 85°C.

Taoglas Limited Substitutes (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS): All three Taoglas parts are ROHS3 compliant with REACH unaffected status. These parts feature brass bodies with gold finish and gold-plated center contacts. Operating temperature range is -55°C to 50°C. Insertion loss is specified at 0.38dB for all three variants.

WITHWAVE Substitutes (VC03FS001, VC03FS002): Both WITHWAVE parts maintain the 2.92mm connector style, 50 ohm impedance, and compression contact termination. These parts feature stainless steel bodies with gold-plated center contacts. RoHS and mating cycle specifications are not provided for these parts.

Frequently Asked Questions (FAQ)

Q: Can RF292A2JDFA be directly replaced with RF292A2JEGA?

A: Yes. Both parts are manufactured by Bulgin and maintain identical electrical and mechanical specifications including connector style, impedance, contact termination, mounting configuration, and frequency rating. Both are ROHS3 compliant and active in production.

Q: What is the primary difference between RF292DJB and RF292A2JDFA?

A: The RF292DJB extends the operating temperature range to -55°C to 125°C compared to -40°C to 85°C for the RF292A2JDFA. All other electrical and mechanical parameters remain identical. This makes RF292DJB suitable for applications requiring extended thermal performance.

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

A: Both parts maintain identical electrical specifications and mounting configurations. The primary difference is that 02K721-40MS3 specifies insertion loss at 0.25dB, while 02K722-40MS3 does not provide insertion loss specification. Both are suitable for 2.92mm coaxial connector applications requiring 40 GHz operation.

Q: What distinguishes Taoglas parts from Bulgin parts?

A: Taoglas parts (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) feature brass bodies with gold finish and gold-plated center contacts, compared to stainless steel bodies in Bulgin parts. Taoglas parts operate across -55°C to 50°C temperature range with 0.38dB insertion loss. All maintain 50 ohm impedance and 40 GHz frequency capability.

Q: Can WITHWAVE VC03FS001 and VC03FS002 be used as direct substitutes?

A: Both WITHWAVE parts maintain the critical electrical parameters: 2.92mm connector style, 50 ohm impedance, compression contact termination, and 40 GHz frequency capability. However, mating cycle and RoHS compliance specifications are not provided for these parts. Verification of application requirements is necessary before selection.

Q: What is the significance of the flange mounting feature?

A: The flange mounting feature indicates panel mount configuration with threaded fastening. All identified substitute parts maintain this mounting specification, ensuring mechanical compatibility with existing panel cutouts and fastening hardware.

Q: Are there temperature range limitations when selecting a substitute?

A: Operating temperature ranges vary among substitutes. RF292A2JDFA operates -40°C to 85°C. RF292DJB extends to -55°C to 125°C. Taoglas and Rosenberger parts operate -55°C to 50°C and 0°C to 85°C respectively. Application temperature requirements must be matched to the selected substitute's operating range.

Q: Do all substitutes maintain 500 mating cycles?

A: RF292A2JDFA, RF292A2JEGA, RF292DJB, Rosenberger parts, and all Taoglas parts specify 500 mating cycles. WITHWAVE parts do not provide mating cycle specifications. For applications requiring defined mating cycle performance, Bulgin, Rosenberger, and Taoglas substitutes are recommended.

Q: What is the difference between PCB.292FST.2H.XS and PCB.292FST.4H.XS?

A: Both Taoglas parts maintain identical electrical specifications, impedance, frequency rating, and insertion loss. The designation difference (2H versus 4H) indicates mounting hole configuration. Both are suitable for 2.92mm coaxial connector applications with identical RF performance.
