Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G18MCSDSMR are identified based on strict equivalence of core electrical and mechanical parameters. The substitution logic requires matching the following critical specifications:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Position count: 18 positions
• Termination: Crimp
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surfaces
• Current capacity: 5.5A minimum
• Shielding: Shielded configuration
• Insert material: PEEK
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part FGG.2B.318.CYCD92 (LEMO manufacturer) satisfies all mandatory matching parameters. Both connectors are actively produced, maintain equivalent electrical performance characteristics, and support identical termination and fastening methodologies.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD2G18MCSDSMR and FGG.2B.318.CYCD92 are actively produced connectors with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on the following engineering considerations:

JBXFD2G18MCSDSMR (Souriau-Sunbank by Eaton):

• Specified voltage rating of 660V provides explicit electrical performance documentation
• Operating temperature range of -40°C to 125°C suits standard industrial and instrumentation applications
• Chrome over nickel shell finish provides corrosion resistance
• Contact finish thickness of 19.7µin (0.50µm) meets standard gold plating specifications
• Current inventory of 903 units supports immediate procurement

FGG.2B.318.CYCD92 (LEMO):

• Extended operating temperature range of -55°C to 250°C accommodates extreme thermal environments
• Chrome shell finish provides corrosion protection
• Contact finish thickness of 39.4µin (1.00µm) provides enhanced gold plating durability
• Specified cable opening range of 0.323" to 0.362" (8.20mm to 9.20mm) supports defined cable compatibility
• Current inventory of 702 units available for procurement

Both connectors satisfy the core electrical and mechanical requirements for 18-position circular connector applications requiring crimp termination, push-pull fastening, and shielded configuration. Selection should prioritize application-specific temperature requirements and voltage specification documentation needs.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.318.CYCD92 directly replace JBXFD2G18MCSDSMR in existing assemblies?

A: Yes, both connectors share identical position count (18), termination method (crimp), fastening type (push-pull), current rating (5.5A), and insert material (PEEK). Physical mating compatibility requires verification of shell size and orientation specifications in the application design documentation.

Q: What is the significance of the different contact finish thicknesses?

A: The JBXFD2G18MCSDSMR specifies 19.7µin (0.50µm) gold plating thickness, while FGG.2B.318.CYCD92 specifies 39.4µin (1.00µm). The thicker plating on the LEMO connector provides extended contact durability and wear resistance in high-cycle mating applications.

Q: Why is the voltage rating specified for one connector but not the other?

A: The JBXFD2G18MCSDSMR explicitly documents a 660V voltage rating. The FGG.2B.318.CYCD92 does not include voltage rating specification in the provided technical data. Applications requiring explicit voltage documentation should reference the JBXFD2G18MCSDSMR or obtain complete electrical specifications from LEMO.

Q: How do the operating temperature ranges affect substitution decisions?

A: The JBXFD2G18MCSDSMR operates from -40°C to 125°C, suitable for standard industrial environments. The FGG.2B.318.CYCD92 operates from -55°C to 250°C, supporting extreme thermal applications. Selection depends on application temperature requirements. The LEMO connector is suitable for all temperature ranges where the Souriau-Sunbank connector operates, plus extended high-temperature environments.

Q: Are both connectors RoHS3 compliant?

A: Yes, both JBXFD2G18MCSDSMR and FGG.2B.318.CYCD92 are ROHS3 compliant with unlimited moisture sensitivity levels (MSL 1), supporting deployment in regulated industries and applications requiring environmental compliance documentation.

Q: What packaging considerations apply to these connectors?

A: The JBXFD2G18MCSDSMR is supplied in standard packaging with 903 units currently in inventory. The FGG.2B.318.CYCD92 is supplied in bulk packaging with 702 units in inventory. Procurement quantities and delivery schedules should account for available inventory levels and packaging configurations.
