FGA.0B.303.CLAD42Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.303.CLAD42Z 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 and maintains full RoHS3 compliance.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the connector interface requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.0B.303.CLAD42Z is determined by strict alignment of the following parameters:

• Connector type and pin configuration (Plug, Male Pins, 3-position)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Shielding requirement (Shielded)
• Contact finish specification (Gold plating on mating surfaces)
• Ingress protection rating (IP50 minimum)
• Insert material (PEEK)
• Compliance certifications (RoHS3)

The substitute part S20LAC-P03MJG0-420S from ODU meets these core substitution criteria. Both connectors share identical connector topology, termination approach, and material specifications for the insert. Both maintain RoHS3 compliance and IP50 ingress protection.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.303.CLAD42Z and S20LAC-P03MJG0-420S maintain active product status and full RoHS3 compliance. Selection between these parts depends on application-specific requirements:

The FGA.0B.303.CLAD42Z supports extended operating temperatures from -55°C to 250°C and provides 8A current capacity. This specification is appropriate for applications requiring high-temperature operation or elevated current demands.

The S20LAC-P03MJG0-420S operates within -40°C to 120°C and carries a 7.5A current rating. This part is suitable for applications within this temperature and current envelope. The ODU connector includes integrated strain relief and is specified for industrial, medical, military, and testing equipment applications.

Both connectors share identical core electrical and mechanical interfaces, enabling substitution when application parameters fall within the overlapping operational envelope of both parts.

Frequently Asked Questions (FAQ)

Q: Can S20LAC-P03MJG0-420S directly replace FGA.0B.303.CLAD42Z in all applications?

A: Direct substitution is valid only when the application operates within the temperature range of -40°C to 120°C and current requirements do not exceed 7.5A. The FGA.0B.303.CLAD42Z supports extended temperature operation to 250°C and 8A current capacity. Verify application requirements against both specifications before substitution.

Q: What are the key compatibility factors between these connectors?

A: Both connectors share identical connector topology (3-position plug with male pins), termination method (solder cup), fastening mechanism (push-pull), shielding configuration, and insert material (PEEK). These parameters ensure mechanical and electrical interface compatibility.

Q: Are there differences in cable opening specifications?

A: The FGA.0B.303.CLAD42Z accepts cable diameters of 0.126" to 0.165" (3.20mm to 4.20mm). The S20LAC-P03MJG0-420S accepts 0.118" to 0.165" (3.00mm to 4.20mm). The ODU part accommodates slightly smaller minimum cable diameters. Verify cable diameter compatibility with the selected connector.

Q: Do both parts meet the same compliance standards?

A: Both connectors are RoHS3 compliant and REACH unaffected. Both carry the same ECCN (EAR99) and HTSUS classification (8536.69.4020).

Q: What is the significance of the shell finish difference?

A: The FGA.0B.303.CLAD42Z features chrome plating on brass. The S20LAC-P03MJG0-420S features chrome over nickel plating on brass. Both finishes provide corrosion resistance and are suitable for the specified ingress protection rating (IP50).
