FGA.1B.303.CLAD52 Equivalent & Substitute Parts

Part Overview

The FGA.1B.303.CLAD52 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 product is active and in stock with 796 units available. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary connector becomes unavailable or when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.1B.303.CLAD52 is determined by strict alignment of the following parameters:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Contact finish: Gold plating on mating surfaces
• Current capacity: 12A minimum
• Ingress protection: IP50 or equivalent
• Mounting configuration: Free hanging (in-line)
• Regulatory compliance: ROHS3 compliant

The substitute part S11LAC-P03MPH0-5200 (ODU MINI-SNAP® L series) meets all mandatory electrical and mechanical parameters. Variations in shell size designation, operating temperature range, and backshell plating specification do not preclude substitution when the core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.303.CLAD52 and S11LAC-P03MPH0-5200 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

The FGA.1B.303.CLAD52 is suitable for applications requiring extended operating temperature range (-55°C to 250°C) and standard chrome shell finish.

The S11LAC-P03MPH0-5200 is suitable for applications operating within -40°C to 120°C and where chrome-over-nickel plating provides enhanced corrosion resistance. Both connectors support identical electrical performance (12A current rating) and mechanical interface (3-position, push-pull, solder cup).

Frequently Asked Questions (FAQ)

Q: Can S11LAC-P03MPH0-5200 be used as a direct replacement for FGA.1B.303.CLAD52?

A: Yes, when application operating temperature remains within -40°C to 120°C. Both connectors share identical connector type, position count, termination method, fastening mechanism, shielding, contact finish, current rating, and ingress protection rating.

Q: What is the primary difference between these two connectors?

A: Operating temperature range and shell finish specification. The FGA.1B.303.CLAD52 operates from -55°C to 250°C with chrome finish, while the S11LAC-P03MPH0-5200 operates from -40°C to 120°C with chrome-over-nickel finish. Cable opening tolerances also differ slightly.

Q: Are both connectors RoHS compliant?

A: Yes, both are ROHS3 compliant and REACH unaffected.

Q: What is the current rating for both connectors?

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

Q: Do both connectors use the same termination method?

A: Yes, both use solder cup termination for wire attachment.
