Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (LEMO FGG Series):

The LEMO FGG.2B.302.CLAD52 and FGG.2B.302.CLAD62 are the most direct substitutes for the JBXFD2G02MSSDSMR. Both parts maintain identical connector type (Plug, Male Pins), position count (2), termination method (Solder Cup), fastening type (Push-Pull), orientation (G), shielding configuration, insert material (PEEK), and flammability rating (UL94 V-0). Both are ROHS3 compliant and active in production.

The primary difference between FGG.2B.302.CLAD52 and FGG.2B.302.CLAD62 is the cable opening specification: CLAD52 accommodates 0.165" ~ 0.205" (4.20mm ~ 5.20mm) cable diameters, while CLAD62 accommodates 0.205" ~ 0.244" (5.20mm ~ 6.20mm) cable diameters. Selection between these two depends on the cable diameter used in the application.

Both LEMO parts have a current rating of 25A, which is lower than the main part's 30A rating. Applications requiring the full 30A capacity must account for this reduction. Both LEMO parts support an extended operating temperature range of -55°C ~ 250°C compared to the main part's -40°C ~ 125°C range.

Secondary Substitute (LEMO FFA Series):

The LEMO FFA.2S.302.CLAC62 differs from the main part in connector type: it features Female Sockets and Male Pins rather than Male Pins only. This part maintains 2 positions, solder cup termination, push-pull fastening, shielding, PEEK insert material, and UL94 V-0 flammability rating. The orientation is Keyed rather than G. Current rating is 20A, and operating temperature range is -55°C ~ 250°C. This part is suitable only when the application design permits the use of a connector with both female sockets and male pins.

PEI-Genesis Substitutes (FGG.2B.302.CLAD72 and FGG.2B.302.CLAD92):

Limited technical specifications are provided for the PEI-Genesis FGG.2B.302.CLAD72 and FGG.2B.302.CLAD92 parts. Both are described as position circular connectors with 2 positions and are active in production. The CLAD72 designation indicates a 7.2mm diameter specification, and CLAD92 indicates a 9.2mm diameter specification. Detailed electrical and mechanical parameters are not provided in the available data. These parts should be selected only when complete technical specifications have been obtained and verified against application requirements.

Compliance and Certification:

All listed substitute parts are ROHS3 compliant and active in production status. The JBXFD2G02MSSDSMR, FGG.2B.302.CLAD52, and FGG.2B.302.CLAD62 all carry REACH Unaffected status and EAR99 ECCN classification. The FFA.2S.302.CLAC62 also carries REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.302.CLAD52 and FGG.2B.302.CLAD62 be used interchangeably with JBXFD2G02MSSDSMR?

A: Both LEMO parts are functionally compatible with the main part based on connector type, position count, termination method, fastening type, and shielding configuration. The primary difference is cable opening diameter. FGG.2B.302.CLAD52 accepts cables 4.20mm ~ 5.20mm in diameter, while FGG.2B.302.CLAD62 accepts cables 5.20mm ~ 6.20mm in diameter. Selection depends on the cable diameter specified in your application. Both parts have a 25A current rating versus the main part's 30A rating.

Q: What is the significance of the cable opening specification?

A: The cable opening dimension defines the range of cable diameters that can be properly terminated into the connector's solder cup. Using a cable outside the specified range may result in improper termination, mechanical stress, or electrical performance degradation. FGG.2B.302.CLAD52 is suitable for smaller diameter cables, while FGG.2B.302.CLAD62 accommodates larger diameter cables.

Q: Why does FFA.2S.302.CLAC62 have a lower current rating (20A) than the main part (30A)?

A: The FFA.2S.302.CLAC62 features both female sockets and male pins in a single connector body, which affects the internal contact geometry and current-carrying capacity. This design difference results in a 20A current rating. This part should be selected only when the application design specifically requires a connector with both socket and pin contacts.

Q: What is the difference between orientation "G" and "Keyed"?

A: Orientation "G" refers to a specific keying arrangement that prevents incorrect mating. "Keyed" orientation also prevents incorrect mating but uses a different keying mechanism. These are not directly interchangeable without mechanical redesign of the mating interface. The FFA.2S.302.CLAC62 uses Keyed orientation, while the main part and other LEMO FGG parts use G orientation.

Q: Are the PEI-Genesis parts (CLAD72 and CLAD92) suitable substitutes?

A: The PEI-Genesis parts FGG.2B.302.CLAD72 and FGG.2B.302.CLAD92 are listed as position circular connectors with 2 positions and active product status. However, detailed electrical and mechanical specifications are not provided in the available technical data. Before selecting these parts, obtain complete technical specifications and verify compatibility with your application requirements, including current rating, voltage rating, operating temperature range, and cable opening dimensions.

Q: What does the "CLAD" designation in the part number indicate?

A: The "CLAD" designation in LEMO part numbers indicates the cable opening diameter specification. CLAD52 specifies 5.2mm nominal cable diameter range, CLAD62 specifies 6.2mm nominal cable diameter range, CLAD72 specifies 7.2mm nominal cable diameter range, and CLAD92 specifies 9.2mm nominal cable diameter range. This designation is critical for proper cable termination.

Q: Can I use a substitute part with a lower current rating in my application?

A: No. If your application requires the full 30A current capacity of the JBXFD2G02MSSDSMR, you cannot use substitute parts with lower current ratings (FGG.2B.302.CLAD52 and FGG.2B.302.CLAD62 at 25A, or FFA.2S.302.CLAC62 at 20A). Using a connector with insufficient current rating may result in overheating, contact degradation, and circuit failure. Select a substitute part only if your application current requirement is within the substitute part's rated capacity.

Q: What is the significance of the extended operating temperature range in LEMO parts?

A: The LEMO FGG and FFA parts support operating temperatures from -55°C to 250°C, compared to the main part's -40°C to 125°C range. If your application operates outside the main part's temperature range, a LEMO substitute may provide additional thermal margin. However, verify that all other components in your assembly are also rated for the extended temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (FGG.2B.302.CLAD52, FGG.2B.302.CLAD62, FFA.2S.302.CLAC62, FGG.2B.302.CLAD72, and FGG.2B.302.CLAD92) are ROHS3 compliant, matching the main part's compliance status.
