Substitute Part Grouping Explanation

Substitute parts for the RF292A2JDFB are identified based on strict electrical and mechanical parameter matching. All substitute connectors share the following core specifications: 2.92mm connector style, jack female socket configuration, 50 ohm impedance, panel mount with flange mounting feature, compression contact termination, screw shield termination, threaded fastening, 40 GHz maximum frequency, 250 V voltage rating, single port configuration, and 500 mating cycles. These parameters define the functional interchangeability of the connector within RF applications.

Substitute parts are grouped into two categories:

Bulgin Parametric Equivalents: RF292A2JEGA and RF292DJB maintain identical electrical specifications and mounting characteristics. RF292DJB extends the operating temperature range to -55°C ~ 125°C compared to the main part's -40°C ~ 85°C range.

Cross-Manufacturer Equivalents: Rosenberger (02K721-40MS3, 02K722-40MS3), Taoglas Limited (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS), and WITHWAVE CO LTD (VC03FS001, VC03FS002) provide functionally equivalent 2.92mm female jack connectors with identical core RF and mechanical parameters. These alternatives support supply chain diversification and application-specific material or plating requirements.

Engineering Selection Recommendations

Bulgin Parametric Equivalents (RF292A2JEGA, RF292DJB): These parts are direct Bulgin alternatives with identical electrical and mechanical specifications to the RF292A2JDFB. RF292A2JEGA maintains the same operating temperature range (-40°C ~ 85°C). RF292DJB extends the operating temperature range to -55°C ~ 125°C, suitable for applications requiring enhanced thermal performance. All three Bulgin variants are ROHS3 compliant and REACH unaffected.

Rosenberger Cross-Manufacturer Equivalents (02K721-40MS3, 02K722-40MS3): These connectors provide equivalent RF and mechanical performance with ROHS3 compliance. Operating temperature range is 0°C ~ 85°C, which is narrower than the main part at the lower end. 02K721-40MS3 specifies 0.25 dB insertion loss. Both parts are REACH affected.

Taoglas Limited Equivalents (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS): These connectors feature brass body material with gold finish and gold center contact plating, differing from the stainless steel construction of the main part. Operating temperature range is -55°C ~ 50°C. All three variants specify 0.38 dB insertion loss and are ROHS3 compliant with REACH unaffected status.

WITHWAVE CO LTD Equivalents (VC03FS001, VC03FS002): These connectors provide equivalent RF and mechanical specifications with stainless steel body and gold center contact plating. Operating temperature, mating cycles, and RoHS status are not specified in available documentation.

Selection should be based on application-specific requirements including operating temperature range, material compatibility, insertion loss specifications, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: What defines electrical interchangeability between RF292A2JDFB and its substitutes?

A: All substitute parts maintain identical core RF specifications: 2.92mm connector style, 50 ohm impedance, 40 GHz maximum frequency, and 250 V voltage rating. These parameters ensure functional compatibility in RF circuit applications. Connector type (jack, female socket), contact termination (compression), and shield termination (screw) are also identical across all listed substitutes.

Q: Are there operating temperature differences between the main part and substitutes?

A: Yes. The RF292A2JDFB operates from -40°C to 85°C. RF292DJB extends this to -55°C ~ 125°C. Rosenberger parts (02K721-40MS3, 02K722-40MS3) operate from 0°C to 85°C. Taoglas parts (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) operate from -55°C to 50°C. Application thermal requirements determine which substitute is appropriate.

Q: What material differences exist between substitutes?

A: The RF292A2JDFB features stainless steel body material. Taoglas Limited substitutes (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) use brass body with gold finish. Rosenberger and WITHWAVE parts use stainless steel. Material selection affects mechanical durability and environmental resistance.

Q: Do all substitutes have specified insertion loss values?

A: No. The main part RF292A2JDFB does not specify insertion loss. Rosenberger 02K721-40MS3 specifies 0.25 dB. Taoglas parts (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) specify 0.38 dB. WITHWAVE and Rosenberger 02K722-40MS3 do not provide insertion loss specifications. Applications requiring low insertion loss should reference specified values.

Q: Are all substitutes ROHS3 compliant?

A: Bulgin parts (RF292A2JDFB, RF292A2JEGA, RF292DJB), Rosenberger parts (02K721-40MS3, 02K722-40MS3), and Taoglas parts (PCB.292FST.2H.XS, PCB.292FST.4H.XS, VMPCB.292FST.A.XS) are ROHS3 compliant. WITHWAVE parts (VC03FS001, VC03FS002) do not specify RoHS status in available documentation.

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

A: Both Taoglas parts share identical electrical and mechanical specifications, including 40 GHz frequency, 50 ohm impedance, compression termination, and 0.38 dB insertion loss. The designation difference (2H vs. 4H) indicates mounting hole configuration. Both are functionally equivalent for RF performance.

Q: Can WITHWAVE VC03FS001 and VC03FS002 be used interchangeably with RF292A2JDFB?

A: Both WITHWAVE parts maintain the core RF specifications (2.92mm, 50 ohm, 40 GHz, female jack socket, compression termination). However, operating temperature range, mating cycle rating, and RoHS compliance status are not specified. Verification against application requirements is necessary before selection.

Q: What is the significance of the REACH status designation?

A: REACH status indicates regulatory compliance under the European Union's Registration, Evaluation, Authorization and Restriction of Chemicals regulation. Bulgin and Taoglas parts are REACH unaffected. Rosenberger parts are REACH affected. WITHWAVE status is not specified. Selection depends on regulatory requirements for the end application and geographic market.

Q: Are all substitutes rated for 500 mating cycles?

A: Bulgin, Rosenberger, and Taoglas parts are all rated for 500 mating cycles. WITHWAVE parts do not specify mating cycle rating in available documentation. Applications requiring high cycle reliability should reference specified values.
