Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.308.CLAD76Z is determined by the following critical parameters:

• Connector Type & Gender: Must be Plug with Male Pins
• Position Count: Must be 8 positions
• Termination Method: Must be Solder Cup
• Fastening Mechanism: Must be Push-Pull
• Shielding: Must be Shielded
• Contact Finish: Must be Gold-plated for mating surfaces
• Ingress Protection: Must meet or exceed IP50
• Insert Material: Must be Polyetheretherketone (PEEK)
• Regulatory Compliance: Must be ROHS3 Compliant and REACH Unaffected

The substitute part S21L0C-P08MFG0-770S (ODU MINI-SNAP® L series) satisfies all critical substitution parameters while maintaining functional equivalence for applications requiring 8-position shielded circular connectors with solder cup termination and push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.308.CLAD76Z and S21L0C-P08MFG0-770S are active products with full regulatory compliance (ROHS3 and REACH Unaffected). Selection between these parts should be based on application-specific requirements:

The FGG.1B.308.CLAD76Z supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The S21L0C-P08MFG0-770S operates within -40°C to 120°C and provides a higher current rating of 7.5A compared to the 5A rating of the LEMO connector. Both connectors feature compatible cable opening ranges with minimal overlap variance. The ODU substitute includes strain relief features in addition to backshell provisions.

Frequently Asked Questions (FAQ)

Q: Can S21L0C-P08MFG0-770S be used as a direct replacement for FGG.1B.308.CLAD76Z?

A: Both connectors meet the core substitution criteria: 8-position, male plug, solder cup termination, push-pull fastening, shielded design, gold-plated contacts, IP50 protection, and PEEK inserts. Compatibility depends on application temperature and current requirements. The LEMO part supports -55°C to 250°C operation, while the ODU part operates -40°C to 120°C. The ODU part supports 7.5A versus the LEMO part's 5A rating.

Q: Are there mechanical compatibility concerns between these connectors?

A: Cable opening specifications are compatible within acceptable tolerances. LEMO specifies 0.283" to 0.299" (7.20mm to 7.60mm), while ODU specifies 0.276" to 0.303" (7.00mm to 7.70mm). Both use identical push-pull fastening mechanisms and PEEK insert materials.

Q: What regulatory certifications apply to both parts?

A: Both the FGG.1B.308.CLAD76Z and S21L0C-P08MFG0-770S are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and 8536.69.4020 HTSUS code.

Q: How do the current ratings differ between these connectors?

A: The FGG.1B.308.CLAD76Z is rated for 5A maximum current, while the S21L0C-P08MFG0-770S is rated for 7.5A. Applications requiring currents between 5A and 7.5A must use the ODU substitute.

Q: What is the difference in operating temperature ranges?

A: The LEMO FGG.1B.308.CLAD76Z operates from -55°C to 250°C, providing a wider temperature envelope. The ODU S21L0C-P08MFG0-770S operates from -40°C to 120°C. Applications requiring operation below -40°C or above 120°C must use the LEMO connector.
