FGA.0B.304.CLAD42Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.304.CLAD42Z is a 4-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 901 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit interchangeability based on electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ODU S20LAC-P04MFG0-420S qualifies as a substitute based on the following critical parameters that determine interchangeability:

• Connector Type & Configuration: Both are 4-position male plug connectors with solder cup termination and push-pull fastening
• Electrical Characteristics: Both support 7A+ current rating with gold-plated mating contacts and shielded construction
• Mechanical Compatibility: Both feature brass shells with chrome plating, PEEK inserts, and compatible cable opening ranges (3.00mm ~ 4.20mm vs. 3.20mm ~ 4.20mm)
• Environmental Protection: Both provide IP50 ingress protection and are ROHS3 compliant
• Termination Method: Both use solder cup termination suitable for identical PCB assembly processes

Substitution is valid where the operating temperature range of the substitute (-40°C ~ 120°C) meets application requirements within this narrower window compared to the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.304.CLAD42Z and S20LAC-P04MFG0-420S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The LEMO part supports an extended operating temperature range (-55°C to 250°C), making it suitable for applications requiring extreme temperature performance. The ODU substitute provides equivalent electrical performance with a 7.5A current rating and is suitable for applications operating within -40°C to 120°C. Selection between these parts should be based on application temperature requirements and connector series compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the ODU S20LAC-P04MFG0-420S directly replace the LEMO FGA.0B.304.CLAD42Z in all applications?

A: Direct replacement is valid for applications where the operating temperature range does not exceed -40°C to 120°C. Both connectors share identical 4-position solder cup configuration, push-pull fastening, gold-plated contacts, and IP50 shielding. Verify application temperature requirements before substitution.

Q: What are the key differences between these two connector models?

A: The primary differences are operating temperature range (LEMO: -55°C to 250°C; ODU: -40°C to 120°C), shell finish (LEMO: Chrome; ODU: Chrome over Nickel), current rating (LEMO: 7A; ODU: 7.5A), and cable opening tolerance (LEMO: 3.20mm ~ 4.20mm; ODU: 3.00mm ~ 4.20mm). Both use identical termination methods and insert materials.

Q: Are both parts RoHS compliant?

A: Yes, both the FGA.0B.304.CLAD42Z and S20LAC-P04MFG0-420S are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the cable opening tolerance difference, and does it affect compatibility?

A: The LEMO part accepts cables 3.20mm to 4.20mm in diameter, while the ODU part accepts 3.00mm to 4.20mm. The ODU part accommodates a slightly smaller minimum cable diameter. Verify your cable diameter falls within the selected connector's specified range.

Q: Can these connectors be used interchangeably in PCB assembly?

A: Both connectors use solder cup termination and are compatible with standard PCB assembly processes. Physical connector dimensions and mating interface differences may require mechanical design verification before interchangeability in existing assemblies.
