Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1G05MSSDSR is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Number of positions: 5
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded configuration
• Contact finish: Gold plating on mating surfaces
• Insert material: PEEK
• Current rating: 9A minimum
• Material flammability: UL94 V-0

Acceptable Variations:

• Shell size designation (1 vs. 305 nomenclature represents equivalent physical dimensions across manufacturers)
• Cable opening diameter (varies by backshell design: 3.10-4.20mm, 4.20-5.20mm, or 7.20-7.60mm)
• Operating temperature range (substitute parts rated -55°C ~ 250°C exceed the main part requirement of -40°C ~ 125°C)
• Contact finish thickness (0.50µm vs. 1.00µm both provide adequate gold plating)
• Shell finish (Chrome vs. Chrome over Nickel both provide corrosion protection)

Non-Substitutable Parameters:

• Voltage rating specification (main part rated 660V; substitute parts do not specify voltage rating and therefore cannot be confirmed as equivalent for high-voltage applications)

All four substitute parts meet the core electrical and mechanical requirements for direct substitution in applications where voltage rating confirmation is not critical.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (JBXFD1G05MSSDSR): Use the original Souriau-Sunbank part when voltage rating of 660V is a specified requirement and when the operating temperature range of -40°C ~ 125°C is sufficient for the application.

Secondary Selection (FGG.1B.305.CLAD52 - LEMO): This part offers the highest inventory availability (16,988 pieces) and is recommended as the first substitute option. It meets all core electrical and mechanical parameters with identical current rating (9A), gold contact finish, PEEK insert, and push-pull fastening. The extended operating temperature range (-55°C ~ 250°C) provides additional thermal margin. Cable opening specification of 4.20-5.20mm accommodates standard backshell designs. ROHS3 compliance and REACH unaffected status match the main part.

Tertiary Selection (FGG.1B.305.CLAD42 - LEMO): This variant provides equivalent functionality with a narrower cable opening range (3.10-4.20mm), suitable for applications using smaller diameter backshells. Inventory of 890 pieces supports moderate-volume requirements.

Quaternary Selection (FGG.1B.305.CLAD76 - LEMO): This variant accommodates larger cable diameters (7.20-7.60mm) for applications requiring thicker backshell assemblies. Inventory of 792 pieces is available.

Limited Data Selection (FGG.1B.305.CLAD52Z - PEI-Genesis): This part is listed as a substitute but contains incomplete technical specifications. Use only when other options are exhausted and when the application does not require confirmed voltage rating or detailed electrical parameter verification. Inventory of 2,000 pieces is available.

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.305.CLAD52 directly replace JBXFD1G05MSSDSR in all applications?

A: FGG.1B.305.CLAD52 meets all specified electrical and mechanical parameters including 5-position configuration, 9A current rating, gold contact finish, solder cup termination, push-pull fastening, and PEEK insert material. However, the main part specifies 660V voltage rating while the LEMO substitute does not provide voltage rating data. Substitution is valid for applications where voltage rating is not a critical specification or where 660V operation is not required.

Q: What is the difference between the three LEMO cable opening variants (CLAD42, CLAD52, CLAD76)?

A: The cable opening diameter determines backshell compatibility. CLAD42 accommodates 3.10-4.20mm cable diameters, CLAD52 accommodates 4.20-5.20mm, and CLAD76 accommodates 7.20-7.60mm. Select the variant matching your backshell assembly cable diameter specification. All three variants are electrically and mechanically equivalent for the connector plug itself.

Q: Are the LEMO FGG.1B.305 series connectors physically compatible with the Souriau-Sunbank JBX series?

A: Both series use identical 5-position circular connector architecture with push-pull fastening and solder cup termination. The shell size designation (1 vs. 305) represents equivalent physical dimensions across manufacturers. Mechanical mating compatibility is confirmed by the identical connector type, position count, and fastening mechanism.

Q: What is the significance of the extended operating temperature range (-55°C ~ 250°C) on LEMO substitutes compared to the main part (-40°C ~ 125°C)?

A: The LEMO parts are rated for a wider temperature range, which exceeds the main part specification. This provides additional thermal margin and allows use in more extreme environments. For applications operating within the original -40°C ~ 125°C range, both parts perform identically.

Q: Why does FGG.1B.305.CLAD52Z have incomplete technical specifications?

A: FGG.1B.305.CLAD52Z is listed as a substitute based on part number equivalence and RoHS3 compliance, but detailed electrical and mechanical parameters are not provided in the available data. This part should be used only when other fully-specified alternatives are unavailable, and verification with the manufacturer (PEI-Genesis) is recommended before design implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (FGG.1B.305.CLAD42, FGG.1B.305.CLAD52, FGG.1B.305.CLAD52Z, and FGG.1B.305.CLAD76) are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original JBXFD1G05MSSDSR.

Q: Which substitute part offers the best inventory availability?

A: FGG.1B.305.CLAD52 (LEMO) has the highest inventory with 16,988 pieces in stock, compared to 890 pieces for CLAD42, 792 pieces for CLAD76, and 2,000 pieces for CLAD52Z. For high-volume or time-sensitive requirements, FGG.1B.305.CLAD52 is the recommended choice.
