Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1G08MSSDSR are qualified based on the following critical parameters that must match or exceed the main part specifications:

Core Compatibility Parameters:

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

Substitution Variance Allowed: The substitute parts listed differ primarily in cable opening specifications, which determine the range of cable diameters that can be accommodated. The LEMO FGG.1B.308 series provides multiple cable opening variants (CLAD42, CLAD52, CLAD62, CLAD72, CLAD76) to support different cable gauges while maintaining electrical and mechanical compatibility. The PEI-Genesis variants (FGG.1B.308.CLAD42, FGG.1B.308.CLAD52Z, FGG.1B.308.CLAD62Z) offer equivalent functionality with alternative sourcing.

All substitute parts maintain the same 8-position configuration, solder cup termination, push-pull fastening, and shielded design required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All listed substitute parts are active production items with ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the JBXFD1G08MSSDSR.

Cable Opening Selection:

The primary differentiator among substitute parts is cable opening specification. Selection must be based on the actual cable diameter used in the application:

• FGG.1B.308.CLAD42 (4.2mm nominal): Smallest cable diameter accommodation
• FGG.1B.308.CLAD52 (4.20mm ~ 5.20mm range): Narrow cable range
• FGG.1B.308.CLAD52Z (5.2mm nominal): Mid-range cable diameter
• FGG.1B.308.CLAD62 (5.20mm ~ 6.20mm range): Medium cable range
• FGG.1B.308.CLAD62Z (6.2mm nominal): Larger cable diameter
• FGG.1B.308.CLAD72 (6.20mm ~ 7.20mm range): Large cable range
• FGG.1B.308.CLAD76 (7.20mm ~ 7.60mm range): Largest cable diameter accommodation

Manufacturer Sourcing:

LEMO FGG.1B.308 series variants (CLAD52, CLAD62, CLAD72, CLAD76) provide documented operating temperature range of -55°C ~ 250°C, exceeding the JBXFD1G08MSSDSR specification of -40°C ~ 125°C. These parts are suitable for applications requiring extended temperature performance.

PEI-Genesis variants (CLAD42, CLAD52Z, CLAD62Z) offer alternative sourcing with equivalent electrical and mechanical specifications.

Inventory Availability:

All substitute parts maintain active production status with available inventory: FGG.1B.308.CLAD52Z (1584 units), FGG.1B.308.CLAD42 (771 units), FGG.1B.308.CLAD62Z (758 units), FGG.1B.308.CLAD72 (802 units), FGG.1B.308.CLAD76 (812 units), FGG.1B.308.CLAD62 (693 units), FGG.1B.308.CLAD52 (975 units).

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308 series connectors directly replace the JBXFD1G08MSSDSR?

A: Yes, FGG.1B.308 series connectors are direct functional replacements when cable opening specifications match the application requirements. All variants maintain identical 8-position configuration, solder cup termination, push-pull fastening, shielded design, and 5A current rating.

Q: What determines which cable opening variant to select?

A: Cable opening specification must accommodate the outer diameter of the cable used in the application. Select the variant whose cable opening range includes your cable diameter. For example, if your cable diameter is 5.5mm, select CLAD62 (5.20mm ~ 6.20mm range) or CLAD52Z (5.2mm nominal).

Q: Are there temperature rating differences between substitute parts?

A: Yes. LEMO FGG.1B.308 variants specify -55°C ~ 250°C operating temperature, while the original JBXFD1G08MSSDSR specifies -40°C ~ 125°C. PEI-Genesis variants do not provide documented operating temperature specifications. For applications requiring extended temperature performance, LEMO variants are preferred.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the JBXFD1G08MSSDSR. All parts carry UL94 V-0 material flammability rating.

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

A: LEMO variants (CLAD52, CLAD62, CLAD72, CLAD76) provide documented operating temperature ranges and ingress protection ratings (IP50). PEI-Genesis variants (CLAD42, CLAD52Z, CLAD62Z) offer equivalent electrical and mechanical specifications with alternative sourcing but do not provide complete technical documentation for operating temperature and ingress protection.

Q: Can I use a connector with a different cable opening range than my cable diameter?

A: No. Cable opening specification must match the cable diameter to ensure proper strain relief and mechanical retention. Using an incorrect cable opening variant may result in inadequate cable support or inability to properly seat the cable.

Q: Are contact finish specifications identical across all variants?

A: Yes. All substitute parts feature gold-plated mating contacts. LEMO variants specify 39.4µin (1.00µm) contact finish thickness, while the original part specifies 19.7µin (0.50µm). Both thicknesses provide equivalent gold contact performance for the 5A current rating.

Q: What is the shell finish difference between the original part and substitutes?

A: The JBXFD1G08MSSDSR features chrome over nickel shell finish, while LEMO and PEI-Genesis variants feature chrome finish. Both finishes provide equivalent corrosion resistance and shielding effectiveness for the specified applications.
