FGG.0B.307.CLAD31Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.307.CLAD31Z is a 7-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is classified as a shielded, push-pull fastening connector with gold-plated mating contacts and chrome-finished brass shell. The part is currently active in production with 998 units in stock. Substitute parts are identified when equivalent functional specifications, termination methods, and electrical ratings align with the original component, enabling direct replacement in applications where the connector form factor and performance characteristics remain compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.307.CLAD31Z is determined by the following critical parameters:

• Connector Type & Gender: Plug with male pins (fixed requirement)
• Position Count: 7 positions (fixed requirement)
• Termination Method: Solder cup (fixed requirement)
• Fastening Mechanism: Push-pull (fixed requirement)
• Shielding: Shielded configuration (fixed requirement)
• Contact Finish: Gold-plated mating contacts (fixed requirement)
• Shell Material & Finish: Brass with chrome finish (fixed requirement)
• Ingress Protection: IP50 minimum (fixed requirement)
• Regulatory Compliance: ROHS3 compliant (fixed requirement)

The substitute part S20L0C-P07MCC0-320S from ODU meets all critical substitution criteria. Both connectors share identical functional specifications for connector type, position count, termination method, fastening type, shielding, contact finish, shell material composition, ingress protection rating, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.307.CLAD31Z and S20L0C-P07MCC0-320S are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The ODU S20L0C-P07MCC0-320S substitute provides a higher current rating of 4A compared to the LEMO original's 2.5A rating, offering increased electrical capacity for the same connector footprint. The shell finish specification differs slightly, with the ODU part featuring chrome over nickel plating versus chrome plating on the LEMO connector; both finishes provide equivalent corrosion resistance and contact reliability.

The operating temperature range represents a key differentiation: the LEMO FGG.0B.307.CLAD31Z operates across -55°C to 250°C, while the ODU S20L0C-P07MCC0-320S operates across -40°C to 120°C. Selection between these parts must account for the specific thermal environment of the application. Applications requiring operation below -40°C or above 120°C necessitate the LEMO original component.

Cable opening specifications show compatible overlap, with both connectors accepting cable diameters within the 2.30mm to 3.20mm range (ODU range extends to 2.00mm minimum).

Frequently Asked Questions (FAQ)

Q: Can the ODU S20L0C-P07MCC0-320S directly replace the LEMO FGG.0B.307.CLAD31Z in all applications?

A: Direct replacement is possible when the application operating temperature remains within -40°C to 120°C. Applications requiring the extended temperature range of the LEMO connector (-55°C to 250°C) require the original part.

Q: What is the significance of the higher 4A current rating on the ODU substitute?

A: The ODU connector's 4A rating exceeds the LEMO original's 2.5A rating. This provides additional electrical capacity margin for the same physical connector. Applications operating at or near 2.5A can safely use the ODU substitute without current derating concerns.

Q: Are the shell finish specifications functionally equivalent?

A: Yes. Both chrome and chrome over nickel finishes provide equivalent corrosion resistance, contact reliability, and environmental protection for shielded connector applications. The finish difference does not affect electrical or mechanical performance.

Q: What cable diameter range is acceptable for both connectors?

A: Both connectors accept cable diameters within the overlapping range of 2.30mm to 3.20mm. The ODU connector additionally accepts cables as small as 2.00mm diameter.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the LEMO FGG.0B.307.CLAD31Z and ODU S20L0C-P07MCC0-320S are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial component selection.

Q: What is the primary substitution criterion for 7-position circular connectors with solder cup termination?

A: Substitution requires matching connector type (plug, male pins), position count (7), termination method (solder cup), fastening mechanism (push-pull), shielding configuration (shielded), contact finish (gold), shell material (brass), and regulatory compliance status (ROHS3). Operating temperature range and current rating must be verified against specific application requirements.
