• EAR99 export classification

The substitute parts listed below maintain these core parameters while accommodating variations in cable opening dimensions and operating temperature ranges specific to individual connector designs.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and UL94 V-0 flammability ratings consistent with the JBXFD1A08MSSDSR. Selection among substitute parts should be based on the following factors:

Cable Opening Compatibility: The LEMO FGG.1B.308 series substitutes are differentiated by cable opening dimensions. The CLAD52 variant accommodates 4.20mm to 5.20mm cable diameters, CLAD62 accommodates 5.20mm to 6.20mm, CLAD72 accommodates 6.20mm to 7.20mm, and CLAD76 accommodates 7.20mm to 7.60mm. Selection must align with the specific cable gauge used in the application.

Operating Temperature Range: The JBXFD1A08MSSDSR operates from -40°C to 125°C. LEMO FGG.1B.308 series connectors extend the upper operating temperature to 250°C, providing enhanced thermal capability for high-temperature applications. This extended range does not compromise compatibility with standard operating conditions.

Ingress Protection Rating: The JBXFD1A08MSSDSR provides IP40 protection. LEMO FGG.1B.308 series connectors provide IP50 dust protection, offering enhanced environmental sealing suitable for applications with elevated particulate exposure.

Manufacturer Availability: LEMO FGG.1B.308 series parts demonstrate consistent inventory levels across all cable opening variants, with 693 to 812 pieces in stock. PEI-Genesis FGG.1B.308 variants (CLAD42 and CLAD52Z) provide alternative sourcing with 771 and 1584 pieces respectively.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308.CLAD52 directly replace JBXFD1A08MSSDSR in existing assemblies?

A: Yes. Both connectors share identical core specifications: 8-position male pin configuration, solder cup termination, push-pull fastening, 5A current rating, gold contact finish, shielded design, PEEK inserts, and ROHS3 compliance. The primary difference is cable opening range (4.20mm to 5.20mm for CLAD52). Compatibility depends on the cable diameter used in the assembly.

Q: What is the significance of different CLAD variants (CLAD42, CLAD52, CLAD62, CLAD72, CLAD76)?

A: The CLAD designation indicates cable opening diameter range. CLAD42 accommodates 4.2mm cables, CLAD52 accommodates 4.2mm to 5.2mm, CLAD62 accommodates 5.2mm to 6.2mm, CLAD72 accommodates 6.2mm to 7.2mm, and CLAD76 accommodates 7.2mm to 7.6mm. Selection must match the cable gauge in the application to ensure proper strain relief and environmental sealing.

Q: Are there differences in shell finish between the main part and substitutes?

A: The JBXFD1A08MSSDSR features chrome over nickel plating. LEMO FGG.1B.308 series connectors use chrome plating without the nickel undercoat. Both finishes provide corrosion resistance and are ROHS3 compliant. The chrome-over-nickel finish of the main part provides additional corrosion protection in harsh environments.

Q: What is the impact of the extended operating temperature range in LEMO substitutes?

A: LEMO FGG.1B.308 series connectors operate from -55°C to 250°C, compared to -40°C to 125°C for the JBXFD1A08MSSDSR. This extended range accommodates high-temperature applications without compromising performance in standard temperature ranges. Applications limited to -40°C to 125°C operation experience no functional difference.

Q: How does IP50 protection in LEMO substitutes compare to IP40 in the main part?

A: IP40 protection prevents contact with objects larger than 1mm and provides limited dust protection. IP50 protection prevents dust ingress entirely. LEMO FGG.1B.308 series connectors provide enhanced environmental sealing suitable for applications with elevated particulate exposure, dust, or outdoor deployment. Standard indoor applications experience no functional difference.

Q: Are contact finish thickness specifications critical for substitution?

A: The JBXFD1A08MSSDSR specifies 19.7µin (0.50µm) gold contact finish thickness. LEMO FGG.1B.308 series connectors specify 39.4µin (1.00µm) thickness. Both thicknesses provide adequate gold plating for mating surface protection and electrical conductivity. The thicker LEMO plating provides extended contact life in high-cycle mating applications.

Q: What packaging considerations apply to these substitutes?

A: The JBXFD1A08MSSDSR is supplied in standard packaging. All listed substitutes are supplied in bulk packaging. Bulk packaging is suitable for manufacturing environments with standard component handling procedures. No special packaging requirements apply to these connector types.

Q: Can PEI-Genesis FGG.1B.308 variants substitute for LEMO variants?

A: FGG.1B.308.CLAD42 and FGG.1B.308.CLAD52Z from PEI-Genesis share the same core electrical and mechanical specifications as LEMO variants. Selection between manufacturers depends on cable opening requirements and inventory availability. Both manufacturers provide ROHS3 compliant products with identical connector functionality.
