Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G19MSSDSMR are qualified based on the following critical parameters that determine functional equivalence:

Core Compatibility Parameters:

• Number of Positions: 19 (exact match required)
• Connector Type: Plug, Male Pins (exact match required)
• Termination: Solder Cup (exact match required)
• Fastening Type: Push-Pull (exact match required)
• Shielding: Shielded (exact match required)
• Current Rating: 5A (exact match required)
• Contact Finish - Mating: Gold (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• Insert Material: Polyetheretherketone (PEEK) (exact match required)

Allowable Parameter Variations:

• Shell Size designation may differ between manufacturers (Shell Size - Insert: 2 vs. 319)
• Operating Temperature Range: Substitute parts may exceed the minimum requirement
• Ingress Protection: Substitute parts may exceed IP40 specification
• Contact Finish Thickness: Substitute parts may exceed minimum thickness requirement
• Voltage Rating: Not specified for substitute parts; primary part specifies 660V

The identified substitute parts FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z from LEMO manufacturer satisfy all core compatibility parameters while maintaining compliance with RoHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The JBXFD2G19MSSDSMR remains the preferred selection when available. This part is actively manufactured and maintained by Souriau-Sunbank by Eaton with confirmed inventory of 661 units. The part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for industrial, instrumentation, medical, and telecommunications applications.

Substitute Part Selection Criteria:

FGG.2B.319.CLAD82 (LEMO) is suitable as a substitute when:

• Cable opening requirements fall within 0.283" to 0.323" (7.20mm to 8.20mm)
• Enhanced ingress protection (IP50) is acceptable or beneficial
• Extended operating temperature range (-55°C to 250°C) is required
• Increased contact finish thickness (39.4µin) is acceptable
• Inventory availability of 1082 units supports procurement timeline

FGG.2B.319.CLAD92Z (LEMO) is suitable as a substitute when:

• Cable opening requirements fall within 0.323" to 0.362" (8.20mm to 9.20mm)
• Enhanced ingress protection (IP50) is acceptable or beneficial
• Extended operating temperature range (-55°C to 250°C) is required
• Increased contact finish thickness (39.4µin) is acceptable
• Inventory availability of 865 units supports procurement timeline

Both LEMO substitute parts maintain compliance with RoHS3 and REACH requirements. The primary distinction between FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z is the cable opening specification, which determines compatibility with specific cable gauges used in the assembly.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.319.CLAD82 or FGG.2B.319.CLAD92Z be used as direct replacements for JBXFD2G19MSSDSMR?

A: Yes, both LEMO parts satisfy the core functional requirements for 19-position circular connector plugs with male pins, solder cup termination, and push-pull fastening. All three parts maintain identical pin count, termination method, current rating, contact finish material, and flammability rating. The substitute parts exceed the ingress protection and operating temperature specifications of the primary part.

Q: What is the difference between FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z?

A: The primary difference is cable opening specification. FGG.2B.319.CLAD82 accommodates cables with outer diameter of 0.283" to 0.323" (7.20mm to 8.20mm), while FGG.2B.319.CLAD92Z accommodates cables with outer diameter of 0.323" to 0.362" (8.20mm to 9.20mm). Selection depends on the cable gauge used in the assembly. All other electrical and mechanical parameters are identical between these two parts.

Q: Are there voltage rating differences between the primary part and substitute parts?

A: The primary part JBXFD2G19MSSDSMR specifies a voltage rating of 660V. The LEMO substitute parts (FGG.2B.319.CLAD82 and FGG.2B.319.CLAD92Z) do not specify a voltage rating in the provided data. When voltage rating is a critical design parameter, the primary part specification should be referenced.

Q: Do the substitute parts meet the same regulatory compliance as the primary part?

A: Yes. All three parts carry ROHS3 compliance and REACH Unaffected status. All parts are rated UL94 V-0 for material flammability. The substitute parts from LEMO maintain equivalent compliance posture to the Souriau-Sunbank primary part.

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

A: The primary part specifies 19.7µin (0.50µm) gold contact finish thickness, while the LEMO substitute parts specify 39.4µin (1.00µm). The thicker gold plating on substitute parts provides enhanced durability and wear resistance during mating cycles. This represents an improvement over the primary part specification and does not create compatibility issues.

Q: How do operating temperature ranges affect part selection?

A: The primary part operates from -40°C to 125°C. Both LEMO substitute parts operate from -55°C to 250°C, providing extended temperature capability. If the application requires operation only within the -40°C to 125°C range, either the primary part or substitute parts are suitable. If extended temperature operation is required, the LEMO substitute parts provide additional margin.

Q: What does IP40 versus IP50 ingress protection mean for connector selection?

A: IP40 (primary part) provides protection against solid objects larger than 1mm and splash water. IP50 (substitute parts) provides dust protection and water jet protection. The higher IP50 rating on substitute parts offers enhanced environmental sealing, making them suitable for applications with greater exposure to dust or moisture. This represents an improvement and does not create compatibility issues.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory levels are: JBXFD2G19MSSDSMR (661 units), FGG.2B.319.CLAD82 (1082 units), and FGG.2B.319.CLAD92Z (865 units). All parts maintain adequate stock levels. Procurement timeline and volume requirements may influence part selection based on supplier lead times and minimum order quantities.
