JBXFD1A10MSSDPR Equivalent & Substitute Parts

Part Overview

The JBXFD1A10MSSDPR is a 10-position circular connector plug manufactured by Souriau-Sunbank by Eaton. This male pin connector features solder cup termination, gold-plated mating contacts, and a shielded design suitable for industrial, instrumentation, medical, and telecommunications applications. The connector operates across a temperature range of -40°C to 125°C with a current rating of 2.5A and voltage rating of 300V. The part is active in production status and maintains full ROHS3 compliance with unlimited moisture sensitivity level rating.

Substitute parts are necessary when original equipment availability is limited, when alternative sourcing reduces lead times, or when design flexibility permits accommodation of compatible connector variants with equivalent electrical and mechanical specifications.

Engineering Selection Recommendations

All listed LEMO substitute parts maintain active production status and full ROHS3 compliance equivalent to the JBXFD1A10MSSDPR. Selection among the five LEMO variants is determined solely by cable jacket diameter requirements:

FGG.1B.310.CLAD52 and FGG.1B.310.CLAD52Z accommodate cable diameters from 4.20mm to 5.20mm. These variants are functionally identical with the distinction that FGG.1B.310.CLAD52Z carries a not applicable moisture sensitivity level designation compared to the standard MSL 1 rating of FGG.1B.310.CLAD52.

FGG.1B.310.CLAD62 accommodates cable diameters from 5.20mm to 6.20mm and is suitable for mid-range cable jacket specifications.

FGG.1B.310.CLAD72 accommodates cable diameters from 6.20mm to 7.20mm for larger cable assemblies.

FGG.1B.310.CLAD76 accommodates cable diameters from 7.20mm to 7.60mm for the largest cable jacket applications.

All substitute parts exceed the original part's operating temperature range (-55°C to 250°C versus -40°C to 125°C) and provide enhanced ingress protection at IP50 rating compared to the original IP40 specification. These characteristics represent functional improvements without introducing compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can LEMO FGG.1B.310 series connectors directly replace the Souriau-Sunbank JBXFD1A10MSSDPR in existing assemblies?

A: Direct replacement is possible when cable jacket diameter falls within the specified cable opening range of the selected LEMO variant. The electrical interface, pin configuration, termination method, and mechanical mating characteristics are equivalent across all listed parts.

Q: What determines which LEMO variant to select?

A: Cable jacket diameter is the sole determining factor. Measure the outer diameter of the cable to be terminated and select the LEMO part whose cable opening range encompasses that measurement. All other electrical and mechanical specifications are identical across variants.

Q: Are there voltage rating differences between the original part and LEMO substitutes?

A: The original JBXFD1A10MSSDPR specifies a 300V voltage rating. LEMO substitute parts do not list a voltage rating in the provided specifications. Voltage compatibility must be confirmed through LEMO technical documentation if the application requires voltage rating verification.

Q: Do the LEMO substitutes maintain the same contact finish thickness?

A: No. The original part specifies 19.7µin (0.50µm) gold contact finish thickness, while LEMO parts specify 39.4µin (1.00µm). The thicker LEMO contact finish provides enhanced durability and wear resistance.

Q: What is the difference between FGG.1B.310.CLAD52 and FGG.1B.310.CLAD52Z?

A: Both parts accommodate identical cable opening specifications (4.20mm to 5.20mm). The distinction lies in moisture sensitivity level designation: FGG.1B.310.CLAD52 carries MSL 1 (Unlimited) while FGG.1B.310.CLAD52Z carries not applicable MSL status. Electrical and mechanical performance are equivalent.

Q: Do substitute parts require any design modifications?

A: No design modifications are required provided the cable jacket diameter matches the selected variant's cable opening specification. The solder cup termination, pin configuration, and mating interface are fully compatible with the original part's application.

Q: What is the inventory status of substitute parts?

A: FGG.1B.310.CLAD52 has 824 units in stock, FGG.1B.310.CLAD52Z has 864 units, FGG.1B.310.CLAD62 has 745 units, FGG.1B.310.CLAD72 has 931 units, and FGG.1B.310.CLAD76 has 1081 units available as new original stock.
