JBXFD2G03MSSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G03MSSDSR is a 3-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with solder cup termination. This connector is designed for industrial, instrumentation, medical, and telecommunications applications requiring reliable signal and power transmission in demanding environments. The part maintains active product status with 810 units in current inventory.

Substitute parts become necessary when original stock availability is limited, when alternative sourcing reduces procurement lead times, or when system design requires connectors from multiple qualified suppliers to ensure supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G03MSSDSR is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination: Solder cup
• Fastening mechanism: Push-Pull
• Shielding configuration: Shielded
• Current capacity: 17A minimum
• Contact finish: Gold plating
• Shell material: Brass construction
• Insert material: PEEK
• Flammability compliance: UL94 V-0

Both LEMO FGG.2B.303.CLAD62 and FGG.2B.303.CLAD92Z meet all primary substitution criteria. These parts are functionally equivalent in connector topology, electrical performance, and mechanical interface. Differences exist only in cable opening dimensions and operating temperature range, which do not affect core substitution eligibility when application requirements are within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

JBXFD2G03MSSDSR (Souriau-Sunbank by Eaton): Primary choice when original equipment manufacturer specification requires Souriau-Sunbank components. Maintains active product status with established supply availability. Complies with ROHS3 and REACH requirements. Operating temperature range of -40°C to 125°C covers standard industrial and telecommunications applications.

FGG.2B.303.CLAD62 (LEMO): Direct functional substitute with identical electrical and mechanical specifications. Supports extended operating temperature range (-55°C to 250°C), providing capability for high-temperature applications beyond the original part's range. Cable opening specification of 5.20mm to 6.20mm accommodates smaller diameter cables. Ingress protection rating of IP50 exceeds the original part's IP40 rating. ROHS3 and REACH compliant.

FGG.2B.303.CLAD92Z (LEMO): Direct functional substitute with identical electrical and mechanical specifications. Supports extended operating temperature range (-55°C to 250°C). Cable opening specification of 8.20mm to 9.20mm accommodates larger diameter cables. Ingress protection rating of IP50 exceeds the original part's IP40 rating. ROHS3 and REACH compliant.

Selection between LEMO substitutes depends on cable diameter requirements: FGG.2B.303.CLAD62 for smaller cables, FGG.2B.303.CLAD92Z for larger cables.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.303.CLAD62 and FGG.2B.303.CLAD92Z be used interchangeably with JBXFD2G03MSSDSR?

A: Both LEMO parts are functionally equivalent substitutes for the Souriau-Sunbank connector. They share identical connector topology, pin configuration, current rating, and termination method. Selection between them depends on cable diameter compatibility. The primary difference is cable opening size: CLAD62 accommodates 5.20mm to 6.20mm diameter cables, while CLAD92Z accommodates 8.20mm to 9.20mm diameter cables.

Q: What are the key differences between these substitute parts?

A: The three connectors are electrically and mechanically equivalent in all critical parameters. Differences include: shell finish (Souriau-Sunbank uses chrome over nickel; LEMO uses chrome), operating temperature range (Souriau-Sunbank: -40°C to 125°C; LEMO: -55°C to 250°C), ingress protection rating (Souriau-Sunbank: IP40; LEMO: IP50), and cable opening dimensions (LEMO parts specify cable opening ranges; Souriau-Sunbank does not). These differences do not affect substitution eligibility for applications within the specified operating parameters.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. JBXFD2G03MSSDSR, FGG.2B.303.CLAD62, and FGG.2B.303.CLAD92Z are all ROHS3 compliant and REACH unaffected. All three parts carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute should I select for high-temperature applications?

A: Both LEMO substitutes (FGG.2B.303.CLAD62 and FGG.2B.303.CLAD92Z) support operating temperatures up to 250°C, compared to the original part's 125°C maximum. For applications requiring extended high-temperature operation, either LEMO part provides superior thermal capability. Cable diameter requirements determine which LEMO variant to select.

Q: What is the significance of the cable opening specification?

A: Cable opening dimensions define the range of cable diameters that can be properly terminated in the solder cup. FGG.2B.303.CLAD62 accepts cables of 5.20mm to 6.20mm diameter, while FGG.2B.303.CLAD92Z accepts cables of 8.20mm to 9.20mm diameter. Verify your cable diameter falls within the specified range for your selected connector variant.

Q: Do these connectors require any special handling or storage conditions?

A: All three connectors carry moisture sensitivity level 1, indicating unlimited shelf life without special moisture control measures. Standard industrial storage conditions are appropriate for all variants.
