Engineering Selection Recommendations

Primary Selection (JBXFD2G18MCSDSR): Select the JBXFD2G18MCSDSR when Souriau-Sunbank by Eaton supply chain is preferred or when existing designs are qualified to this manufacturer's specifications. This part is actively produced with 1137 units in current inventory. Full compliance with ROHS3 and UL94 V-0 standards is confirmed.

Substitute Selection (FGG.2B.318.CYCD92): The LEMO FGG.2B.318.CYCD92 qualifies as a functional equivalent based on matching connector architecture, electrical ratings, and material specifications. This substitute is appropriate when:

Souriau-Sunbank supply is unavailable
LEMO supply chain offers procurement advantages
Extended operating temperature range (-55°C ~ 250°C) is beneficial for the application
Enhanced ingress protection (IP50 vs IP40) is required

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. The LEMO substitute provides thicker gold plating (39.4µin vs 19.7µin), which may extend contact life in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.318.CYCD92 be used as a direct replacement for JBXFD2G18MCSDSR in existing assemblies?

A: Yes. Both connectors share identical 18-position male pin configurations, crimp termination, push-pull fastening, and gold-plated contact surfaces. Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Shell finish—JBXFD2G18MCSDSR uses chrome over nickel; FGG.2B.318.CYCD92 uses chrome only; (2) Ingress protection—JBXFD2G18MCSDSR is IP40; FGG.2B.318.CYCD92 is IP50; (3) Operating temperature range—JBXFD2G18MCSDSR operates -40°C ~ 125°C; FGG.2B.318.CYCD92 operates -55°C ~ 250°C; (4) Contact finish thickness—JBXFD2G18MCSDSR has 0.50µm gold plating; FGG.2B.318.CYCD92 has 1.00µm gold plating.

Q: Are both connectors RoHS compliant?

A: Yes. Both JBXFD2G18MCSDSR and FGG.2B.318.CYCD92 are ROHS3 compliant and carry UL94 V-0 material flammability certification.

Q: What is the current rating for these connectors?

A: Both connectors are rated for 5.5A continuous current.

Q: Which connector should be selected for high-temperature applications?

A: The LEMO FGG.2B.318.CYCD92 supports operating temperatures up to 250°C, compared to 125°C for the Souriau-Sunbank JBXFD2G18MCSDSR. Select the LEMO part for applications requiring extended temperature performance.

Q: Is the thicker gold plating on the LEMO connector significant?

A: The LEMO FGG.2B.318.CYCD92 provides 1.00µm gold plating versus 0.50µm on the JBXFD2G18MCSDSR. Thicker plating may provide improved durability in high-cycle mating applications and enhanced corrosion resistance.

Q: What is the packaging format for each part?

A: JBXFD2G18MCSDSR is supplied in standard packaging. FGG.2B.318.CYCD92 is supplied in bulk packaging.
