JBXFD2G08MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD2G08MCSDSMR is an 8-position circular connector plug manufactured by Souriau-Sunbank by Eaton. This male pin connector features crimp termination, push-pull fastening, and gold-plated mating contacts. The connector is actively produced and maintained in inventory with 803 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where alternative connector designs meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G08MCSDSMR are identified based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

Connector type: Plug with male pins
Position count: 8 positions
Termination: Crimp
Fastening mechanism: Push-Pull
Current capacity: 10A minimum
Shielding: Shielded configuration
Contact finish: Gold plating
Insert material: PEEK
Compliance: ROHS3 and REACH requirements

Allowable Variations:

Shell size designation (different manufacturer nomenclature)
Shell finish specification (Chrome vs. Chrome over Nickel)
Operating temperature range (substitute may exceed minimum range)
Ingress protection rating (substitute may exceed minimum rating)
Contact finish thickness (substitute may exceed minimum thickness)
Backshell features (additional features permitted)

The substitute part FGG.2B.308.CYCD62 from LEMO meets all mandatory matching parameters and is therefore classified as a direct equivalent for the JBXFD2G08MCSDSMR.

Engineering Selection Recommendations

Primary Part: JBXFD2G08MCSDSMR

Select the JBXFD2G08MCSDSMR when:

Souriau-Sunbank by Eaton supply chain is preferred
Operating temperature range of -40°C to 125°C is sufficient
IP40 ingress protection meets application requirements
830V voltage rating is required
Inventory availability of 803 units supports project timeline

Substitute Part: FGG.2B.308.CYCD62

Select the FGG.2B.308.CYCD62 when:

LEMO supply chain is preferred or primary part is unavailable
Extended operating temperature range (-55°C to 250°C) is required
Enhanced ingress protection (IP50) is beneficial
Thicker gold plating (39.4µin vs. 19.7µin) provides additional contact durability
Inventory availability of 698 units supports project timeline

Both parts are ROHS3 compliant, REACH unaffected, and carry active product status. Both meet UL94 V-0 flammability requirements and support 10A current capacity with crimp termination and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.308.CYCD62 be used as a direct replacement for JBXFD2G08MCSDSMR?

A: Yes. Both connectors are 8-position male plug connectors with crimp termination, push-pull fastening, shielded configuration, and gold-plated contacts. Electrical and mechanical specifications are equivalent. Physical dimensions and mating interface compatibility must be verified for the specific application.

Q: What is the difference in operating temperature range?

A: The JBXFD2G08MCSDSMR operates from -40°C to 125°C. The FGG.2B.308.CYCD62 operates from -55°C to 250°C. The substitute part supports a wider temperature envelope and is suitable for applications requiring extended temperature performance.

Q: Are there differences in contact plating thickness?

A: Yes. The JBXFD2G08MCSDSMR has 19.7µin (0.50µm) gold plating on mating contacts. The FGG.2B.308.CYCD62 has 39.4µin (1.00µm) gold plating. The thicker plating on the substitute part provides enhanced contact durability and wear resistance.

Q: What is the difference in ingress protection rating?

A: The JBXFD2G08MCSDSMR is rated IP40. The FGG.2B.308.CYCD62 is rated IP50 (dust protected). The substitute part provides enhanced protection against particulate ingress.

Q: Are both parts RoHS compliant?

A: Yes. Both JBXFD2G08MCSDSMR and FGG.2B.308.CYCD62 are ROHS3 compliant and REACH unaffected.

Q: What is the current rating for both connectors?

A: Both connectors are rated for 10A continuous current.

Q: Do both connectors use the same termination method?

A: Yes. Both connectors use crimp termination and are compatible with standard crimp tooling for 8-position circular connectors.

Q: What is the fastening mechanism for both parts?

A: Both connectors use push-pull fastening for quick-connect and quick-disconnect applications.
