Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G08MCSDSR is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector type: Plug with male pins
• Position count: 8 positions
• Termination method: Crimp
• Fastening mechanism: Push-Pull
• Shielding configuration: Shielded
• Contact finish: Gold plating on mating surfaces
• Current capacity: 10A minimum
• Material flammability: UL94 V-0
• Insert material: Polyetheretherketone (PEEK)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part FGG.2B.308.CYCD62 (LEMO 2B series) meets all critical parameters. Differences in shell size designation (2 vs. 308), ingress protection rating (IP40 vs. IP50), operating temperature range (-40°C ~ 125°C vs. -55°C ~ 250°C), and contact finish thickness (19.7µin vs. 39.4µin) do not preclude substitution when application requirements permit the higher performance specifications of the substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD2G08MCSDSR and FGG.2B.308.CYCD62 maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on application-specific requirements:

JBXFD2G08MCSDSR (Souriau-Sunbank by Eaton) is appropriate for applications operating within the -40°C ~ 125°C temperature range with IP40 ingress protection requirements. This part carries 1113 units in current inventory.

FGG.2B.308.CYCD62 (LEMO) is appropriate for applications requiring extended operating temperature capability (-55°C ~ 250°C) or enhanced ingress protection (IP50). This part carries 698 units in current inventory. The thicker gold contact finish (39.4µin vs. 19.7µin) provides additional wear resistance in high-cycle mating applications.

Both parts are suitable for industrial, instrumentation, medical, and telecommunications applications where 10A current capacity and 830V voltage rating (or higher) are specified.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.308.CYCD62 be used as a direct replacement for JBXFD2G08MCSDSR?

A: Yes, when application requirements permit. Both connectors share identical connector type, position count, termination method, fastening mechanism, shielding configuration, current rating, contact finish material, and regulatory compliance status. The substitute part offers enhanced specifications in temperature range and ingress protection.

Q: What are the differences in shell size designation between these parts?

A: The JBXFD2G08MCSDSR uses shell size designation "2" within the JBX series, while the FGG.2B.308.CYCD62 uses designation "308" within the LEMO 2B series. These designations reflect different manufacturer classification systems and do not indicate incompatibility when other parameters align.

Q: Does the higher ingress protection rating of the LEMO part affect compatibility?

A: No. IP50 (dust protected) is a superset of IP40 protection. The LEMO part provides equal or better environmental sealing. Selection should be based on actual application requirements.

Q: Are the contact finish thicknesses interchangeable?

A: Yes. Both parts use gold plating on mating contacts. The LEMO part features 39.4µin thickness compared to 19.7µin on the Souriau-Sunbank part. Thicker plating extends contact life in high-cycle applications but does not prevent substitution in standard applications.

Q: What is the significance of the extended temperature range on the LEMO part?

A: The FGG.2B.308.CYCD62 operates from -55°C ~ 250°C, compared to -40°C ~ 125°C for the JBXFD2G08MCSDSR. Use the LEMO part only when application temperatures exceed the Souriau-Sunbank part's rated range.

Q: Are both parts available in equivalent packaging quantities?

A: The JBXFD2G08MCSDSR is available in 1113 units (new original stock), while FGG.2B.308.CYCD62 is available in 698 units (bulk packaging). Verify packaging and quantity requirements with procurement specifications.
