FGA.0B.303.CLAD31Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.303.CLAD31Z is a 3-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is designed for applications requiring shielded, push-pull fastening with gold-plated mating contacts and operates across an extended temperature range of -55°C to 250°C. The part is currently active in production with 1055 units in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in compatible applications while maintaining connector integrity and performance requirements.

Key Parameters

Substitute Part Grouping Explanation

The ODU S20LAC-P03MJG0-320S qualifies as a substitute based on the following aligned parameters:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shell material: Brass with chrome finish
• Contact finish: Gold-plated mating surfaces
• Shielding: Shielded configuration
• Ingress protection: IP50 dust protection
• Insert material: PEEK
• Compliance: ROHS3 compliant, REACH unaffected

Substitution is valid where the operating temperature range, current rating, and cable opening specifications of the substitute part satisfy the application requirements of the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.303.CLAD31Z and S20LAC-P03MJG0-320S are active production parts with ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory adherence.

The FGA.0B.303.CLAD31Z supports an extended operating temperature range of -55°C to 250°C and an 8A current rating. The S20LAC-P03MJG0-320S operates within -40°C to 120°C with a 7.5A current rating. Selection between these parts depends on whether the application requires the extended temperature capability and higher current capacity of the LEMO part, or whether the ODU substitute's temperature and current specifications are sufficient for the intended use.

The cable opening range of the ODU part (2.00mm minimum) is narrower than the LEMO part (2.30mm minimum), which may affect compatibility with specific cable gauges.

Frequently Asked Questions (FAQ)

Q: What determines if the S20LAC-P03MJG0-320S can replace the FGA.0B.303.CLAD31Z?

A: Substitution is valid when the application does not require the extended temperature range (-55°C to 250°C) of the LEMO part and operates within the ODU part's -40°C to 120°C range. The current requirement must not exceed 7.5A. Cable gauge must fall within the 2.00mm to 3.20mm opening range.

Q: Are there differences in shell finish between these parts?

A: The FGA.0B.303.CLAD31Z features chrome plating on brass, while the S20LAC-P03MJG0-320S has chrome plating over nickel on brass. Both provide corrosion resistance and meet the specified ingress protection rating.

Q: Do both parts use the same insert material?

A: Yes, both connectors use polyetheretherketone (PEEK) for the insert material, ensuring consistent dielectric properties and thermal stability.

Q: Are both parts compliant with environmental regulations?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Q: What is the inventory status for each part?

A: The FGA.0B.303.CLAD31Z has 1055 units in stock, while the S20LAC-P03MJG0-320S has 911 units in stock inventory.
