FGG.1B.314.CLAD42Z Equivalent & Substitute Parts

Part Overview

The FGG.1B.314.CLAD42Z is a 14-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 1,037 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.314.CLAD42Z is determined by the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Number of positions (14)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold plating)
• Shielding configuration (Shielded)
• Insert material (PEEK)
• Ingress protection rating (IP50 minimum)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitute part S21L0C-P14MCC0-420S meets these core functional requirements. Variations in shell size designation, shell finish specification, current rating, and operating temperature range represent design differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.314.CLAD42Z and S21L0C-P14MCC0-420S are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific thermal and electrical requirements:

The FGG.1B.314.CLAD42Z supports extended operating temperatures from -55°C to 250°C and is suitable for high-temperature applications. The S21L0C-P14MCC0-420S operates within -40°C to 120°C and provides higher current capacity at 4A versus 2A. Both connectors maintain identical core functionality: 14-position shielded plug configuration with push-pull fastening, gold-plated contacts, and solder cup termination. The ODU MINI-SNAP® L series includes integrated strain relief and backshell features. Cable opening specifications are compatible within the stated ranges.

Frequently Asked Questions (FAQ)

Q: Can the S21L0C-P14MCC0-420S directly replace the FGG.1B.314.CLAD42Z?

A: Direct mechanical and electrical substitution is possible when application operating temperatures remain within -40°C to 120°C and current requirements do not exceed 4A. Physical compatibility exists within the specified cable opening ranges. Connector mating interfaces and pin configurations are equivalent.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (LEMO: -55°C to 250°C; ODU: -40°C to 120°C), current rating (LEMO: 2A; ODU: 4A), and shell finish specification (LEMO: Chrome; ODU: Chrome over Nickel). The ODU part includes integrated strain relief features. Both maintain identical position count, termination method, and shielding configuration.

Q: Are both parts compliant with regulatory requirements?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both connectors, indicating no special handling requirements during storage or assembly.

Q: What is the cable opening compatibility between these connectors?

A: The FGG.1B.314.CLAD42Z accepts cables 0.122" to 0.165" (3.10mm to 4.20mm). The S21L0C-P14MCC0-420S accepts cables 0.118" to 0.165" (3.00mm to 4.20mm). The overlapping range of 0.122" to 0.165" ensures compatibility for standard cable sizes.
