Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1G05MSSDSMR are qualified based on the following critical parameters:

Electrical Compatibility:

• 5-position connector configuration
• 9A current rating
• Gold-plated mating contacts
• Shielded design

Mechanical Compatibility:

• Plug connector with male pins
• Solder cup termination
• Push-pull fastening mechanism
• Free-hanging in-line mounting
• PEEK insert material
• Brass shell construction

Environmental & Compliance:

• ROHS3 compliance
• UL94 V-0 flammability rating
• MSL 1 rating
• REACH unaffected status

The LEMO FGG.1B.305 series connectors (FGG.1B.305.CLAD42, FGG.1B.305.CLAD52, FGG.1B.305.CLAD52Z, FGG.1B.305.CLAD76) meet these core substitution criteria. Differences in cable opening specifications and operating temperature ranges reflect design variations within the same functional class and do not preclude substitution where system requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and full ROHS3 compliance, ensuring regulatory alignment with the original JBXFD1G05MSSDSMR. The LEMO FGG.1B.305 series connectors provide equivalent electrical performance at the 9A current rating with gold-plated contacts and shielded construction.

Cable Opening Considerations: Selection among FGG.1B.305.CLAD42, FGG.1B.305.CLAD52, and FGG.1B.305.CLAD76 must be based on cable diameter requirements for your application:

• CLAD42: 3.10mm ~ 4.20mm cable opening
• CLAD52: 4.20mm ~ 5.20mm cable opening
• CLAD76: 7.20mm ~ 7.60mm cable opening

Temperature Range: LEMO substitutes support -55°C ~ 250°C operating temperature, exceeding the original part's -40°C ~ 125°C range. This provides additional thermal margin for demanding applications.

Ingress Protection: LEMO substitutes provide IP50 dust protection versus IP40 on the original part, offering enhanced environmental sealing.

Inventory Availability: FGG.1B.305.CLAD52 maintains the highest stock level (16,988 pieces), followed by FGG.1B.305.CLAD42 (890 pieces) and FGG.1B.305.CLAD76 (792 pieces).

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.305.CLAD52 directly replace JBXFD1G05MSSDSMR in existing designs?

A: Yes, for applications where the 4.20mm ~ 5.20mm cable opening accommodates your cable diameter. Both connectors share identical 5-position, 9A, push-pull, solder cup specifications with gold-plated contacts and PEEK inserts. Verify cable diameter compatibility before implementation.

Q: What is the significance of different cable opening specifications among the LEMO substitutes?

A: Cable opening dimensions determine the range of cable diameters that can be terminated into the connector. CLAD42, CLAD52, and CLAD76 are mechanically identical except for this parameter. Select the variant matching your cable gauge to ensure proper strain relief and electrical contact.

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

A: No. Both the JBXFD1G05MSSDSMR and all listed LEMO substitutes are ROHS3 compliant, MSL 1 rated, and REACH unaffected. All carry UL94 V-0 flammability ratings.

Q: Why do LEMO substitutes have higher operating temperature ratings?

A: The FGG.1B.305 series is rated -55°C ~ 250°C, reflecting the design envelope of the LEMO connector family. This does not affect substitution validity; it indicates the substitute can operate across a wider temperature range than the original specification requires.

Q: What is the difference between IP40 and IP50 ingress protection ratings?

A: IP40 provides protection against objects larger than 1mm and splash water. IP50 provides dust protection and water jet resistance. LEMO substitutes with IP50 offer enhanced environmental sealing suitable for more demanding industrial environments.

Q: Is FGG.1B.305.CLAD52Z a viable substitute?

A: FGG.1B.305.CLAD52Z, manufactured by PEI-Genesis, meets core substitution criteria with ROHS3 compliance and active product status. Limited technical data is provided for this variant; verify detailed specifications with the manufacturer before design implementation.

Q: How should I select between available LEMO substitutes?

A: Primary selection criterion is cable opening diameter. If your application uses 4.20mm ~ 5.20mm diameter cable, FGG.1B.305.CLAD52 is the standard choice with highest availability. For smaller cables (3.10mm ~ 4.20mm), use CLAD42. For larger cables (7.20mm ~ 7.60mm), use CLAD76. All three provide identical electrical and mechanical performance within their respective cable diameter ranges.
