Substitute Part Grouping Explanation

Substitute parts for the RF292DJB are qualified based on strict electrical and mechanical parameter matching. All substitute connectors must meet the following core criteria to ensure functional equivalence:

Critical Matching Parameters:

Connector Style: 2.92mm
Connector Type: Jack, Female Socket
Contact Termination: Compression
Shield Termination: Screw
Impedance: 50 Ohms
Mounting Type: Panel Mount
Mounting Feature: Flange
Fastening Type: Threaded

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are functionally equivalent to the RF292DJB based on core electrical and mechanical parameters. Selection among these alternatives should be based on the following engineering considerations:

Compliance and Regulatory Status: RF292A2JEGA, 02K721-40MS3, 02K722-40MS3, PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS are ROHS3 compliant. VC03FS001 and VC03FS002 do not specify RoHS compliance status in available documentation.

REACH Compliance: RF292DJB, RF292A2JEGA, PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS are REACH Unaffected. 02K721-40MS3 and 02K722-40MS3 are REACH Affected. VC03FS001 and VC03FS002 do not specify REACH status.

Manufacturer Availability: Bulgin RF292A2JEGA provides same-manufacturer substitution with identical core specifications. Rosenberger 02K721-40MS3 and 02K722-40MS3 offer established RF connector manufacturing capability. Taoglas Limited PCB.292FST.2H.XS, PCB.292FST.4H.XS, and VMPCB.292FST.A.XS provide alternative sourcing with documented compliance. WITHWAVE CO LTD VC03FS001 and VC03FS002 provide additional sourcing options.

Operating Temperature Considerations: RF292DJB operates from -55°C to 125°C. RF292A2JEGA operates from -40°C to 85°C, representing a narrower temperature range. Rosenberger parts operate from 0°C to 85°C. Taoglas parts operate from -55°C to 50°C. Applications requiring the full -55°C to 125°C range should prioritize RF292DJB or equivalent parts with matching temperature specifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the RF292DJB?

A: A substitute part must match the RF292DJB in the following core parameters: 2.92mm connector style, jack female socket type, compression contact termination, screw shield termination, 50 ohms impedance, panel mount configuration with flange, threaded fastening, 40 GHz maximum frequency, single port, beryllium copper center contact material, 250 V voltage rating, and 500 mating cycles. All listed substitute parts meet these criteria.

Q: Can I use RF292A2JEGA as a direct replacement for RF292DJB?

A: RF292A2JEGA is electrically and mechanically equivalent to RF292DJB for all core RF and mechanical specifications. Both are manufactured by Bulgin and are ROHS3 compliant. The primary difference is operating temperature range: RF292A2JEGA operates from -40°C to 85°C compared to RF292DJB's -55°C to 125°C range. Applications operating within -40°C to 85°C can use RF292A2JEGA as a direct substitute.

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

A: Both parts are electrically and mechanically equivalent to RF292DJB. The designation difference (2H versus 4H) indicates mounting hole configuration variations. Both maintain identical RF performance, impedance, frequency rating, and contact specifications. Selection between these variants depends on PCB layout and mounting hole requirements.

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

A: Both Rosenberger parts are electrically and mechanically equivalent to RF292DJB and to each other in terms of core RF specifications. Both operate at 40 GHz maximum frequency, 50 ohms impedance, and maintain identical contact and termination specifications. The designation difference reflects internal design variations. Both are suitable substitutes for RF292DJB applications.

Q: What is the significance of REACH Affected status for Rosenberger parts?

A: REACH Affected status indicates that the part contains substances of very high concern (SVHC) that are subject to REACH regulation. Applications in European Union markets or with EU supply chain requirements should prioritize REACH Unaffected parts such as RF292DJB, RF292A2JEGA, Taoglas variants, or verify REACH compliance documentation for specific applications.

Q: Can I use VC03FS001 or VC03FS002 without additional verification?

A: VC03FS001 and VC03FS002 match RF292DJB in all specified core electrical and mechanical parameters. However, these parts do not provide documented specifications for voltage rating, mating cycles, RoHS status, or REACH status. Applications requiring full compliance documentation should prioritize parts with complete specification data such as RF292A2JEGA, Rosenberger, or Taoglas variants.

Q: How do insertion loss specifications affect substitution?

A: Insertion loss is not specified for RF292DJB. Substitute parts with documented insertion loss (02K721-40MS3 at 0.25dB, Taoglas variants at 0.38dB) provide additional performance data but do not preclude substitution. Applications with specific insertion loss requirements should reference complete connector specifications and system performance requirements.

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

A: Taoglas PCB.292FST.2H.XS and PCB.292FST.4H.XS designations indicate 2-hole and 4-hole mounting configurations respectively. RF292DJB and RF292A2JEGA use flange mounting. Rosenberger and WITHWAVE parts maintain flange mounting. PCB layout and mechanical mounting requirements determine which variant is appropriate for specific applications.

Q: Are all substitute parts available in equivalent inventory quantities?

A: Inventory availability varies by part number and supplier. RF292DJB has 863 pieces in stock. Substitute parts range from 759 to 1114 pieces in stock across different suppliers. Inventory status should be confirmed at time of procurement for production planning purposes.
