Substitute Part Grouping Explanation

Substitute parts for the RF292A2JDFE are identified based on 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 capability (40 GHz maximum), number of ports (1), center contact material (beryllium copper), voltage rating (250 V), and mating cycles (500). All substitute parts maintain ROHS3 compliance and MSL 1 rating. Variations in body material, center contact plating, dielectric material, operating temperature range, and insertion loss are noted but do not preclude substitution when the core electrical and mechanical parameters align. Parts are grouped by manufacturer to facilitate sourcing decisions.

Engineering Selection Recommendations

All listed substitute parts maintain full compliance with ROHS3 requirements and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The RF292A2JDFE and RF292A2JEGA are direct parametric equivalents from Bulgin with identical electrical and mechanical specifications. The RF292DJB from Bulgin extends the operating temperature range to -55°C to 125°C, providing enhanced thermal performance for applications requiring extended temperature operation.

Rosenberger parts 02K721-40MS3 and 02K722-40MS3 provide equivalent 2.92mm jack configurations with 40 GHz frequency capability. The 02K721-40MS3 specifies 0.25dB insertion loss and operates from 0°C to 85°C. Both Rosenberger parts carry REACH Affected status, requiring verification against specific regulatory requirements.

Taoglas Limited parts PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS maintain equivalent electrical specifications with brass body material and gold finish. These parts operate from -55°C to 50°C and specify 0.38dB insertion loss. All Taoglas parts carry REACH Unaffected status.

WITHWAVE CO LTD parts VC03FS001 and VC03FS002 provide 2.92mm jack configurations with stainless steel bodies and gold-plated center contacts. Operating temperature and insertion loss specifications are not provided for these parts.

Selection should prioritize parts with active product status and complete specification documentation. Temperature range requirements, insertion loss specifications, and regulatory compliance status must align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can RF292A2JEGA be used as a direct replacement for RF292A2JDFE?

A: Yes. RF292A2JEGA is a parametric equivalent with identical connector style, type, impedance, contact termination, shield termination, mounting configuration, frequency capability, center contact material, body material, voltage rating, and mating cycles. Both parts are manufactured by Bulgin and maintain ROHS3 compliance.

Q: What is the primary difference between RF292DJB and RF292A2JDFE?

A: The RF292DJB extends the operating temperature range to -55°C to 125°C compared to -40°C to 85°C for the RF292A2JDFE. All other electrical and mechanical parameters remain equivalent. RF292DJB is suitable for applications requiring enhanced thermal performance.

Q: Are Taoglas Limited parts compatible with the RF292A2JDFE?

A: Taoglas Limited parts PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS maintain equivalent electrical specifications including 2.92mm connector style, 50 ohm impedance, compression contact termination, and 40 GHz frequency capability. The primary difference is body material composition (brass with gold finish versus stainless steel) and operating temperature range (-55°C to 50°C versus -40°C to 85°C). Substitution is valid when thermal and material specifications align with application requirements.

Q: What does the difference in insertion loss specifications indicate?

A: Insertion loss values are provided for specific substitute parts. The RF292A2JDFE does not specify insertion loss. Rosenberger 02K721-40MS3 specifies 0.25dB insertion loss, while Taoglas parts specify 0.38dB insertion loss. These values indicate signal attenuation at operating frequencies. Selection should consider application sensitivity to insertion loss performance.

Q: Are WITHWAVE CO LTD parts VC03FS001 and VC03FS002 suitable substitutes?

A: VC03FS001 and VC03FS002 maintain equivalent 2.92mm jack configuration, 50 ohm impedance, compression termination, and 40 GHz frequency capability. However, operating temperature range and insertion loss specifications are not provided. Substitution requires verification that application requirements align with available specification data.

Q: What is the significance of REACH status differences?

A: REACH status indicates regulatory compliance under European chemical regulations. RF292A2JDFE and RF292A2JEGA carry REACH Unaffected status. Rosenberger parts carry REACH Affected status, requiring verification against specific regulatory requirements for applications subject to REACH compliance. Taoglas parts carry REACH Unaffected status.

Q: Can parts with different body materials be substituted?

A: Substitution is valid when electrical specifications align. The RF292A2JDFE uses stainless steel body material. Taoglas parts use brass with gold finish. Material differences do not affect electrical performance but may influence mechanical durability, corrosion resistance, and environmental compatibility. Application requirements determine material suitability.

Q: What mounting feature differences exist among substitute parts?

A: All listed substitute parts maintain panel mount configuration with flange mounting feature and threaded fastening type. Mechanical mounting compatibility is maintained across all substitutes.

Q: How should operating temperature range differences be evaluated?

A: The RF292A2JDFE operates from -40°C to 85°C. RF292DJB extends this to -55°C to 125°C. Rosenberger and WITHWAVE parts operate from 0°C to 85°C. Taoglas parts operate from -55°C to 50°C. Selection must ensure the substitute part's temperature range encompasses the application's operating environment.
