FGA.1B.308.CLAD42 Equivalent & Substitute Parts

Part Overview

The FGA.1B.308.CLAD42 is an 8-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 a wide temperature range of -55°C to 250°C. The product is currently active and in stock with 1070 units available. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or design flexibility.

Key Parameters

Substitute Part Grouping Explanation

The S11LAC-P08MFG0-4200 (ODU MINI-SNAP® L series) qualifies as a substitute based on the following critical parameters:

• 8-position circular connector plug with male pins
• Solder cup termination
• Push-pull fastening mechanism
• Shielded configuration with brass shell and chrome finish
• Gold-plated mating contacts
• PEEK insert material
• IP50 ingress protection rating
• ROHS3 compliance

Substitution is valid when these core electrical and mechanical parameters align with application requirements. Differences in operating temperature range, current rating, and shell size designation do not preclude substitution when the application environment and electrical load fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.308.CLAD42 and S11LAC-P08MFG0-4200 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts depends on application-specific constraints:

The FGA.1B.308.CLAD42 is suitable for applications requiring extended operating temperature range up to 250°C. The S11LAC-P08MFG0-4200 supports higher current capacity at 7.5A versus 5A and is applicable to industrial, medical, military, and testing equipment environments within its -40°C to 120°C operating range. Both connectors maintain equivalent mechanical interface characteristics, shielding effectiveness, and contact reliability through gold plating and PEEK insulation.

Frequently Asked Questions (FAQ)

Q: Can the S11LAC-P08MFG0-4200 replace the FGA.1B.308.CLAD42 in all applications?

A: Substitution is valid when the application operating temperature does not exceed 120°C and current draw does not exceed 7.5A. If the application requires operation above 120°C or specifically mandates the -55°C lower temperature limit, the FGA.1B.308.CLAD42 is the appropriate choice.

Q: Are the physical dimensions and mating interfaces identical?

A: Both connectors are 8-position circular plugs with push-pull fastening and solder cup termination. Cable opening specifications are nearly identical (3.00mm to 4.20mm versus 3.10mm to 4.20mm), ensuring compatible cable jacket sizes. Shell size designations differ (308 versus 1), reflecting manufacturer-specific nomenclature rather than functional incompatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the FGA.1B.308.CLAD42 and S11LAC-P08MFG0-4200 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting equivalent regulatory requirements for commercial and industrial applications.

Q: What is the difference in shell finish between chrome and chrome over nickel?

A: The FGA.1B.308.CLAD42 uses chrome finish, while the S11LAC-P08MFG0-4200 uses chrome over nickel. Both finishes provide corrosion resistance and shielding effectiveness. Chrome over nickel offers enhanced durability in certain corrosive environments but does not affect electrical performance for standard applications.

Q: Are solder cup terminations compatible between these two connectors?

A: Yes. Both connectors use solder cup termination with identical functional characteristics, allowing equivalent PCB assembly and wire attachment methods.
