Engineering Selection Recommendations
Both LEMO substitute parts maintain active product status and full compliance with ROHS3 and REACH regulations, matching the primary part's regulatory standing. The selection between JBXFD2G12MSSDSR and its substitutes depends on cable opening requirements and operating temperature range specifications for the application.
JBXFD2G12MSSDSR (Souriau-Sunbank): Select this part when cable opening dimensions are not specified in design requirements and operating temperature range of -40°C to 125°C is sufficient. This part is currently in stock with highest inventory availability (994 units).
FGG.2B.312.CLAD52 (LEMO): Select this substitute when cable opening range of 0.165" to 0.205" (4.20mm to 5.20mm) is required and extended operating temperature range of -55°C to 250°C is necessary. Contact finish thickness is doubled (39.4µin versus 19.7µin), providing enhanced durability in high-cycle mating applications.
FGG.2B.312.CLAD82 (LEMO): Select this substitute when cable opening range of 0.283" to 0.323" (7.20mm to 8.20mm) is required and extended operating temperature range of -55°C to 250°C is necessary. This variant accommodates larger diameter cables while maintaining identical electrical and mechanical specifications to FGG.2B.312.CLAD52.
All three parts are certified to UL94 V-0 flammability standards and feature identical 7A current rating and shielded PEEK insert construction.
Frequently Asked Questions (FAQ)
Q: Can FGG.2B.312.CLAD52 or FGG.2B.312.CLAD82 be used as direct replacements for JBXFD2G12MSSDSR?
A: Yes, both LEMO parts are functionally equivalent substitutes. All three connectors share identical connector type (plug, male pins), position count (12), termination method (solder cup), fastening type (push-pull), orientation (G), shielding configuration, current rating (7A), and insert material (PEEK). Differences exist only in cable opening dimensions, operating temperature range, and contact finish thickness, which are application-specific parameters.
Q: What is the difference between FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82?
A: The primary difference is cable opening dimension. FGG.2B.312.CLAD52 accommodates cables with outer diameter of 0.165" to 0.205" (4.20mm to 5.20mm), while FGG.2B.312.CLAD82 accommodates cables with outer diameter of 0.283" to 0.323" (7.20mm to 8.20mm). All other electrical and mechanical specifications are identical between these two LEMO variants.
Q: Does the JBXFD2G12MSSDSR have a voltage rating specification?
A: Yes, the JBXFD2G12MSSDSR is rated for 830V. The LEMO substitute parts (FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82) do not have voltage rating specifications provided in available documentation.
Q: What is the operating temperature difference between the main part and substitutes?
A: The JBXFD2G12MSSDSR operates from -40°C to 125°C. Both LEMO substitutes (FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82) operate from -55°C to 250°C, providing extended temperature range capability for demanding thermal environments.
Q: Are all three parts RoHS and REACH compliant?
A: Yes, all three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial, instrumentation, medical, and telecommunications applications.
Q: What is the difference in contact finish thickness?
A: The JBXFD2G12MSSDSR has gold contact finish thickness of 19.7µin (0.50µm). Both LEMO substitutes have gold contact finish thickness of 39.4µin (1.00µm), which is double the thickness and provides enhanced wear resistance in high-cycle mating applications.
