JBXFD1G08MSSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1G08MSSDSMR is an 8-position circular connector plug manufactured by Souriau-Sunbank by Eaton. This shielded male pin connector features solder cup termination, gold-plated mating contacts, and is rated for 5A at 600V operation across industrial, instrumentation, medical, and telecommunications applications. The connector operates across -40°C to 125°C and maintains ROHS3 compliance with UL94 V-0 flammability rating.

Substitute parts are necessary when the original JBXFD1G08MSSDSMR is unavailable due to inventory constraints, supply chain disruptions, or when alternative manufacturers offer equivalent electrical and mechanical specifications within the allowed parameter ranges for this connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1G08MSSDSMR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 8
• Termination: Solder Cup
• Fastening Type: Push-Pull
• Orientation: G
• Shell Material: Brass
• Contact Finish - Mating: Gold
• Shielding: Shielded
• Current Rating: 5A
• Insert Material: Polyetheretherketone (PEEK)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Shell Finish: Chrome over Nickel (main part) to Chrome (substitute parts) — both provide equivalent corrosion protection
• Ingress Protection: IP40 (main part) to IP50 (substitute parts) — IP50 provides equal or greater protection
• Operating Temperature Range: -40°C to 125°C (main part) to -55°C to 250°C (substitute parts) — extended range maintains compatibility
• Contact Finish Thickness: 19.7µin (main part) to 39.4µin (substitute parts) — increased thickness maintains durability
• Cable Opening: Varies by substitute part model to accommodate different cable gauges

All substitute parts listed are manufactured by LEMO or PEI-Genesis, both established circular connector manufacturers. All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification identical to the main part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, matching the regulatory framework of the JBXFD1G08MSSDSMR. Selection among substitute parts should be based on the following criteria derived from provided specifications:

Cable Opening Compatibility: Substitute parts differ in cable opening ranges to accommodate various cable gauges. FGG.1B.308.CLAD42 accommodates 4.20mm to 5.20mm cables, FGG.1B.308.CLAD52 accommodates 4.20mm to 5.20mm cables, FGG.1B.308.CLAD62 accommodates 5.20mm to 6.20mm cables, FGG.1B.308.CLAD72 accommodates 6.20mm to 7.20mm cables, and FGG.1B.308.CLAD76 accommodates 7.20mm to 7.60mm cables. Select the substitute part whose cable opening range matches the cable gauge of your application.

Operating Temperature Range: The JBXFD1G08MSSDSMR operates from -40°C to 125°C. LEMO substitute parts (FGG.1B.308.CLAD52, FGG.1B.308.CLAD62, FGG.1B.308.CLAD72, FGG.1B.308.CLAD76) extend this range to -55°C to 250°C, providing enhanced thermal capability for demanding applications. PEI-Genesis parts (FGG.1B.308.CLAD42, FGG.1B.308.CLAD52Z) do not specify operating temperature ranges.

Contact Finish Thickness: LEMO substitute parts provide 39.4µin (1.00µm) gold plating thickness compared to the main part's 19.7µin (0.50µm), offering increased contact durability and wear resistance for high-cycle mating applications.

Ingress Protection: All substitute parts provide IP50 dust protection, exceeding the main part's IP40 rating, suitable for environments with higher particulate contamination.

Inventory Availability: FGG.1B.308.CLAD52Z maintains the highest inventory level at 1584 pieces, followed by FGG.1B.308.CLAD76 at 812 pieces and FGG.1B.308.CLAD72 at 802 pieces.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308.CLAD52 directly replace JBXFD1G08MSSDSMR in my application?

A: FGG.1B.308.CLAD52 is electrically and mechanically equivalent to JBXFD1G08MSSDSMR across all critical parameters: 8-position solder cup termination, 5A current rating, push-pull fastening, shielded construction, and PEEK insert material. The substitute part accommodates cables in the 4.20mm to 5.20mm range. Verify your cable gauge falls within this range before substitution.

Q: What is the difference between the various FGG.1B.308.CLAD models?

A: The FGG.1B.308.CLAD series differs only in cable opening diameter ranges. The numeric suffix indicates the cable opening range: CLAD42 (4.20-5.20mm), CLAD52 (4.20-5.20mm), CLAD62 (5.20-6.20mm), CLAD72 (6.20-7.20mm), and CLAD76 (7.20-7.60mm). All other electrical and mechanical specifications remain identical. Select the model matching your cable gauge.

Q: Are LEMO and PEI-Genesis substitute parts interchangeable with each other?

A: LEMO parts (FGG.1B.308.CLAD52, FGG.1B.308.CLAD62, FGG.1B.308.CLAD72, FGG.1B.308.CLAD76) and PEI-Genesis parts (FGG.1B.308.CLAD42, FGG.1B.308.CLAD52Z) are functionally equivalent within their respective cable opening ranges. Both manufacturers provide identical connector type, position count, termination method, and contact specifications. Selection between manufacturers should be based on cable opening compatibility and inventory availability.

Q: Does the extended operating temperature range of LEMO parts affect compatibility?

A: No. The LEMO substitute parts' extended operating temperature range (-55°C to 250°C) is a superset of the main part's range (-40°C to 125°C). Applications operating within the original -40°C to 125°C specification remain fully compatible. The extended range provides additional capability for future applications without affecting current compatibility.

Q: Why do substitute parts specify IP50 instead of IP40?

A: IP50 provides dust protection equivalent to or greater than IP40. This represents an improvement in ingress protection, not a deviation. Applications requiring IP40 protection are fully satisfied by IP50-rated connectors.

Q: What does the shell finish difference (Chrome over Nickel vs. Chrome) mean for compatibility?

A: Both finishes provide corrosion protection for brass shells in industrial environments. Chrome over Nickel (main part) and Chrome (substitute parts) are functionally equivalent for the specified applications. The substitute parts' chrome finish maintains the same protective characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance identical to the JBXFD1G08MSSDSMR, ensuring compatibility with regulatory requirements across industrial, instrumentation, medical, and telecommunications applications.

Q: How do I select between FGG.1B.308.CLAD52 and FGG.1B.308.CLAD52Z?

A: Both parts accommodate 4.20mm to 5.20mm cable openings and are electrically equivalent. FGG.1B.308.CLAD52Z is manufactured by PEI-Genesis with 1584 pieces in stock, while FGG.1B.308.CLAD52 is manufactured by LEMO with 975 pieces in stock. FGG.1B.308.CLAD52 provides specified operating temperature range (-55°C to 250°C) and contact finish thickness (39.4µin). Select based on cable gauge compatibility, inventory availability, and temperature requirements.

Q: Can substitute parts be used in medical applications?

A: The JBXFD1G08MSSDSMR is specified for medical applications. Substitute parts maintain identical electrical specifications, PEEK insert material, UL94 V-0 flammability rating, and ROHS3 compliance. However, medical device applications may require additional qualification or documentation beyond electrical equivalence. Consult application-specific regulatory requirements before substitution in medical devices.
