Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1G07MCSDSR is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (7)
• Termination method (Crimp)
• Fastening type (Push-Pull)
• Contact finish at mating surface (Gold)
• Shielding configuration (Shielded)
• Current rating (7A minimum)
• Insert material (PEEK)
• Flammability rating (UL94 V-0)

Identified Substitute Parts:

The following LEMO circular connectors meet the core compatibility parameters:

1. FGG.1B.307.CYCD62 - LEMO 1B Series, 7-position male plug, crimp termination, push-pull fastening, gold-plated contacts, shielded, PEEK insert, UL94 V-0 rated
2. FGG.1B.307.CYCZ - LEMO 1B Series, 7-position male plug, crimp termination, push-pull fastening, gold-plated contacts, shielded, PEEK insert, UL94 V-0 rated

Both substitute parts are manufactured by LEMO and share the essential functional and electrical characteristics required for direct substitution in applications currently using the JBXFD1G07MCSDSR.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The JBXFD1G07MCSDSR remains the specified component when design documentation explicitly calls for Souriau-Sunbank by Eaton JBX series connectors. This part is active in production, ROHS3 compliant, and REACH unaffected, meeting all regulatory requirements for industrial and medical applications.

Substitute Part Selection Criteria:

FGG.1B.307.CYCD62 and FGG.1B.307.CYCZ are qualified substitutes when:

• The application permits manufacturer substitution from Souriau-Sunbank to LEMO
• Connector form factor, pin count, and electrical ratings are the primary design constraints
• The application does not require specific JBX series designation

Operational Advantages of LEMO Substitutes:

• Extended operating temperature range (-55°C ~ 250°C versus -40°C ~ 125°C) provides thermal margin for demanding environments
• Enhanced ingress protection rating (IP50 versus IP40) offers superior dust protection
• Thicker gold plating (39.4µin versus 19.7µin) extends contact durability in high-cycle mating applications
• Both LEMO parts are active in production with higher inventory availability (829-1094 units versus 658 units)

Regulatory Compliance: All three parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes, ensuring equivalent regulatory treatment in procurement and export scenarios.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.307.CYCD62 or FGG.1B.307.CYCZ be used as direct replacements for JBXFD1G07MCSDSR in existing assemblies?

A: Yes, both LEMO parts are functionally equivalent for applications where the primary design constraints are 7-position male plug configuration, crimp termination, 7A current rating, and push-pull fastening. The connectors share identical pin counts, contact finishes, shielding, and insert materials. Physical form factors are compatible with existing mating receptacles designed for 7-position circular connectors with push-pull fastening.

Q: What are the differences in contact finish specifications between the main part and substitutes?

A: The JBXFD1G07MCSDSR specifies 19.7µin (0.50µm) gold plating thickness, while both LEMO substitutes specify 39.4µin (1.00µm). The thicker plating on LEMO parts provides enhanced durability and contact resistance stability over extended mating cycles. Both thicknesses meet industry standards for gold-plated connector contacts.

Q: Are there temperature rating differences that affect application suitability?

A: The JBXFD1G07MCSDSR operates from -40°C to 125°C, while FGG.1B.307.CYCD62 and FGG.1B.307.CYCZ operate from -55°C to 250°C. The LEMO substitutes provide extended low-temperature capability and significantly higher high-temperature rating. Applications requiring operation above 125°C or below -40°C must use LEMO substitutes.

Q: What is the difference between FGG.1B.307.CYCD62 and FGG.1B.307.CYCZ?

A: Both parts are functionally identical 7-position LEMO male plugs with crimp termination and push-pull fastening. The primary difference is cable opening specification: FGG.1B.307.CYCD62 specifies 0.205" ~ 0.244" (5.20mm ~ 6.20mm) cable opening, while FGG.1B.307.CYCZ does not specify this parameter. Selection between these parts depends on cable diameter requirements for your application.

Q: Do all three parts meet the same regulatory and compliance standards?

A: Yes. The JBXFD1G07MCSDSR, FGG.1B.307.CYCD62, and FGG.1B.307.CYCZ are all ROHS3 compliant, REACH unaffected, UL94 V-0 flammability rated, and classified under identical ECCN (EAR99) and HTSUS (8536.69.4020) codes. All three parts are suitable for industrial, instrumentation, and medical applications requiring equivalent regulatory treatment.

Q: What is the significance of the IP50 ingress protection rating on LEMO substitutes compared to IP40 on the main part?

A: IP50 (dust protected) provides superior protection against dust ingress compared to IP40 (splash protected). The LEMO substitutes are rated for environments with higher dust contamination. If the application environment does not require enhanced dust protection, both ratings are functionally acceptable.

Q: Are there packaging or inventory considerations for substitute selection?

A: The JBXFD1G07MCSDSR is packaged in standard format with 658 units in stock. FGG.1B.307.CYCD62 and FGG.1B.307.CYCZ are supplied in bulk packaging with higher inventory availability (1094 and 829 units respectively). Bulk packaging may offer cost advantages for high-volume procurement.
