FGA.1B.303.CLAD72Z Equivalent & Substitute Parts

Part Overview

The FGA.1B.303.CLAD72Z 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 and in stock with 908 units available. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part S21LAC-P03MPH0-720S (ODU MINI-SNAP® L series) qualifies as an equivalent based on the following critical parameters:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded configuration
• Current capacity: 12A
• Contact finish: Gold-plated mating surfaces
• Ingress protection: IP50 dust protection
• Compliance: ROHS3 compliant, REACH unaffected

The substitute maintains functional and electrical equivalence through matching core specifications. Differences in operating temperature range and shell size designation reflect design variations between manufacturers but do not preclude substitution in applications within the overlapping temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.303.CLAD72Z and S21LAC-P03MPH0-720S meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The primary consideration for component selection is operating temperature range. The LEMO part supports extended high-temperature operation to 250°C, while the ODU substitute operates to 120°C maximum. Selection of the substitute is appropriate for applications where the maximum operating temperature does not exceed 120°C and where the overlapping cable opening range (6.20mm ~ 7.20mm) accommodates the cable gauge requirements. Both parts maintain equivalent electrical performance at the specified 12A current rating with gold-plated contacts and shielded configurations.

Frequently Asked Questions (FAQ)

Q: Can the S21LAC-P03MPH0-720S replace the FGA.1B.303.CLAD72Z in all applications?

A: Substitution is valid for applications where the maximum operating temperature does not exceed 120°C. The LEMO part is required for applications operating above 120°C or up to 250°C.

Q: Are the cable opening dimensions compatible between these parts?

A: The cable opening ranges overlap substantially. The LEMO part accepts 6.20mm ~ 7.20mm cable diameters, while the ODU part accepts 6.00mm ~ 7.20mm. Both accommodate cables within the 6.20mm ~ 7.20mm range.

Q: Do both parts have equivalent shielding and ingress protection?

A: Yes. Both connectors provide shielded configurations with IP50 dust protection rating.

Q: What is the difference in shell finish between these parts?

A: The LEMO part uses chrome plating on brass, while the ODU part uses chrome over nickel plating on brass. Both provide corrosion resistance appropriate for industrial environments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FGA.1B.303.CLAD72Z and S21LAC-P03MPH0-720S are ROHS3 compliant and REACH unaffected.

Q: What is the current rating for both connectors?

A: Both parts are rated for 12A continuous current.
