Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G19MSSDSR is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Position count: 19 positions
• Termination method: Solder cup
• Fastening mechanism: Push-Pull
• Shielding configuration: Shielded
• Contact finish: Gold plating on mating surfaces
• Insert material: PEEK
• Current rating: 5A minimum
• Compliance: ROHS3 and REACH Unaffected status

Identified Substitutes:

• FGG.2B.319.CLAD82 (LEMO manufacturer)
• FGG.2B.319.CLAD92Z (LEMO manufacturer)

Both substitute parts satisfy all primary matching criteria. Differences exist in operating temperature range, ingress protection rating, contact finish thickness, and cable opening specifications. These differences are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

JBXFD2G19MSSDSR (Primary Part): This connector is the specified component and remains the first choice when available. It is actively produced, ROHS3 compliant, and REACH unaffected. The 660V voltage rating is explicitly defined. Operating temperature range is -40°C to 125°C.

FGG.2B.319.CLAD82 (LEMO Substitute): This part is functionally equivalent for applications within the overlapping operating temperature range (-40°C to 125°C). It provides enhanced ingress protection (IP50 versus IP40) and thicker gold plating (39.4µin versus 19.7µin). Cable opening range is 7.20mm to 8.20mm. This substitute is suitable when LEMO sourcing is preferred or when the enhanced dust protection is beneficial. ROHS3 compliant and REACH unaffected.

FGG.2B.319.CLAD92Z (LEMO Substitute): This part is functionally equivalent for applications within the overlapping operating temperature range (-40°C to 125°C). It provides enhanced ingress protection (IP50 versus IP40) and thicker gold plating (39.4µin versus 19.7µin). Cable opening range is 8.20mm to 9.20mm, accommodating larger cable diameters. This substitute is suitable when LEMO sourcing is preferred, when enhanced dust protection is beneficial, or when larger cable diameters are required. ROHS3 compliant and REACH unaffected.

Selection Criteria:

• Use the primary part (JBXFD2G19MSSDSR) when available and when the specified 660V voltage rating is required.
• Use FGG.2B.319.CLAD82 when cable diameter is 7.20mm to 8.20mm and LEMO sourcing is acceptable.
• Use FGG.2B.319.CLAD92Z when cable diameter is 8.20mm to 9.20mm and LEMO sourcing is acceptable.
• All three parts are suitable for industrial, instrumentation, medical, and telecommunications applications within their respective operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z be used interchangeably with JBXFD2G19MSSDSR?

A: Both LEMO parts are functionally equivalent to the Souriau-Sunbank connector for applications operating between -40°C and 125°C. The primary difference is cable opening diameter. FGG.2B.319.CLAD82 accommodates 7.20mm to 8.20mm cable diameters, while FGG.2B.319.CLAD92Z accommodates 8.20mm to 9.20mm cable diameters. Select based on your cable diameter requirement.

Q: What is the significance of the contact finish thickness difference?

A: The JBXFD2G19MSSDSR has 19.7µin (0.50µm) gold plating, while both LEMO substitutes have 39.4µin (1.00µm) gold plating. Thicker plating provides enhanced durability and corrosion resistance in demanding environments. Both thicknesses meet industry standards for gold-plated contacts.

Q: Why do the LEMO parts have a higher ingress protection rating?

A: FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z are rated IP50 (dust protected) compared to IP40 for the JBXFD2G19MSSDSR. This indicates enhanced protection against dust ingress. Both ratings are suitable for industrial and telecommunications applications.

Q: Are there voltage rating differences between these parts?

A: The JBXFD2G19MSSDSR specifies 660V. The LEMO substitutes do not have a voltage rating specified in the available data. If your application requires a specific voltage rating above 5A current capacity, verify LEMO part specifications with the manufacturer before substitution.

Q: What is the operating temperature consideration for substitution?

A: The JBXFD2G19MSSDSR operates from -40°C to 125°C. Both LEMO substitutes operate from -55°C to 250°C. For applications within the -40°C to 125°C range, all three parts are compatible. For applications requiring operation below -40°C or above 125°C, only the LEMO parts are suitable.

Q: Are all three parts RoHS3 compliant?

A: Yes. JBXFD2G19MSSDSR, FGG.2B.319.CLAD82, and FGG.2B.319.CLAD92Z are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: How do I select between the two LEMO substitutes?

A: Selection depends on cable diameter. Measure your cable outer diameter and select FGG.2B.319.CLAD82 for 7.20mm to 8.20mm cables or FGG.2B.319.CLAD92Z for 8.20mm to 9.20mm cables. Both parts are otherwise identical in electrical and mechanical specifications.
