JBXFD1G08MWSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD1G08MWSDSR is an 8-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This connector operates as a free-hanging in-line component with push-pull fastening and is designed for industrial, instrumentation, medical, and telecommunications applications. The part is currently active in production with 698 units in stock. Substitute parts are necessary when specific cable opening requirements, termination methods, or operating temperature ranges differ from the original specification, or when supply chain considerations require alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JBXFD1G08MWSDSR is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Connector type: Plug with male pins
• Number of positions: 8
• Mounting type: Free hanging (in-line)
• Fastening type: Push-pull
• Orientation: G
• Primary material: Metal
• Contact finish: Gold
• Shielding: Shielded
• Current rating: 5A
• Insert material: PEEK
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Determine Substitute Grouping):

• Shell size - insert designation
• Termination method (solder cup vs. other)
• Cable opening range
• Operating temperature range
• Shell finish specification
• Ingress protection rating
• Contact finish thickness

The substitute parts listed below maintain compatibility with the core electrical and mechanical interface requirements while accommodating different cable opening specifications and termination methods.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original JBXFD1G08MWSDSR specification. Selection among substitute parts is determined by cable opening requirements and termination method compatibility:

FGG.1B.308.CLAD42 and FGG.1B.308.CLAD52Z (PEI-Genesis): These parts accommodate smaller cable diameters (4.2mm and 5.2mm respectively) and are suitable for applications with space constraints or specific cable gauge requirements.

FGG.1B.308.CLAD52, FGG.1B.308.CLAD62, FGG.1B.308.CLAD72, and FGG.1B.308.CLAD76 (LEMO): These parts feature solder cup termination and progressively larger cable opening ranges (4.20-5.20mm, 5.20-6.20mm, 6.20-7.20mm, and 7.20-7.60mm respectively). The LEMO series offers extended operating temperature capability (-55°C to 250°C) compared to the original part (-40°C to 125°C) and enhanced ingress protection (IP50 vs. IP40).

All substitute parts maintain the required 5A current rating, 8-position configuration, push-pull fastening, shielded design, and PEEK insert material. The choice of substitute should be based on cable opening compatibility and whether solder cup termination is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308.CLAD series parts directly replace JBXFD1G08MWSDSR in all applications?

A: Direct replacement depends on cable opening requirements and termination method. The JBXFD1G08MWSDSR does not specify cable opening or termination method in the provided data. FGG.1B.308.CLAD series parts feature solder cup termination and specific cable opening ranges. Verify that the cable diameter falls within the specified range of the selected substitute part.

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

A: Cable opening defines the acceptable range of cable diameters that can be terminated to the connector. Each FGG.1B.308.CLAD variant accommodates a different cable diameter range. Selection must match the actual cable gauge used in the application. Undersized or oversized cables relative to the specified opening range will result in improper termination and connection failure.

Q: Are there differences in operating temperature capability between the main part and substitutes?

A: Yes. The JBXFD1G08MWSDSR operates from -40°C to 125°C, while all LEMO FGG.1B.308.CLAD series substitutes operate from -55°C to 250°C. Applications requiring operation below -40°C or above 125°C must use the LEMO substitutes. Applications within the -40°C to 125°C range are compatible with either the original or substitute parts.

Q: What is the difference between the PEI-Genesis and LEMO substitute options?

A: PEI-Genesis parts (FGG.1B.308.CLAD42 and FGG.1B.308.CLAD52Z) do not specify termination method or operating temperature range in the provided data. LEMO parts (FGG.1B.308.CLAD52, CLAD62, CLAD72, CLAD76) explicitly feature solder cup termination and -55°C to 250°C operating temperature. LEMO parts also specify IP50 ingress protection versus IP40 for the original part.

Q: How do I select the correct cable opening specification?

A: Measure the outer diameter of the cable to be terminated. Select the FGG.1B.308.CLAD variant whose cable opening range encompasses this measurement. For example, if cable outer diameter is 5.5mm, select FGG.1B.308.CLAD62 (5.20-6.20mm range). Do not select a part with a cable opening range smaller than the cable diameter.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the regulatory compliance of the original JBXFD1G08MWSDSR.

Q: What is the contact finish thickness difference between the main part and substitutes?

A: The JBXFD1G08MWSDSR specifies 19.7µin (0.50µm) gold contact finish thickness. LEMO FGG.1B.308.CLAD series parts specify 39.4µin (1.00µm), which is twice the thickness. This thicker gold plating provides enhanced wear resistance and contact durability in high-cycle mating applications.
