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

Part Overview

The FGA.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 954 units in stock. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type & Gender: Plug with male pins (fixed requirement)
• Position Count: 14 positions (fixed requirement)
• Termination Method: Solder cup (fixed requirement)
• Fastening Mechanism: Push-pull (fixed requirement)
• Shielding: Shielded configuration (fixed requirement)
• Contact Finish: Gold plating on mating surfaces (fixed requirement)
• Ingress Protection: IP50 minimum (fixed requirement)
• Compliance: ROHS3 compliant (fixed requirement)

The substitute part S21LAC-P14MCC0-420S from ODU meets all critical functional and electrical parameters. Variations in shell size designation (314 vs. 1), operating temperature range (-55°C to 250°C vs. -40°C to 120°C), current rating (2A vs. 4A), and backshell material plating specifications represent design differences that do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.314.CLAD42Z and S21LAC-P14MCC0-420S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The LEMO connector supports extended temperature operation from -55°C to 250°C, while the ODU substitute operates within -40°C to 120°C. Selection between these parts depends on application temperature requirements. The ODU part provides higher current capacity (4A vs. 2A), which may offer design margin in power distribution applications. Both connectors feature identical core specifications: 14-position solder cup termination, push-pull fastening, shielded configuration, gold-plated contacts, and IP50 ingress protection. Cable opening specifications are compatible within the stated ranges. Mechanical interchangeability and electrical performance are equivalent for applications operating within the ODU part's temperature and current specifications.

Frequently Asked Questions (FAQ)

Q: Can the S21LAC-P14MCC0-420S directly replace the FGA.1B.314.CLAD42Z in all applications?

A: Direct substitution is valid when the application operates within -40°C to 120°C temperature range and does not require current levels exceeding 4A. If the application requires the extended -55°C to 250°C temperature range of the LEMO part, the ODU substitute is not suitable.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share identical specifications for position count (14), termination method (solder cup), fastening type (push-pull), shielding (shielded), contact finish (gold), ingress protection (IP50), insert material (PEEK), and orientation (A). These parameters ensure mechanical and electrical compatibility.

Q: Are there differences in cable opening specifications?

A: The LEMO part specifies 0.122" to 0.165" (3.10mm to 4.20mm), while the ODU part specifies 0.118" to 0.165" (3.00mm to 4.20mm). Both ranges overlap sufficiently to accommodate standard cable diameters within the 3.10mm to 4.20mm window.

Q: How do the current ratings differ, and does this affect substitution?

A: The LEMO connector is rated for 2A, while the ODU connector is rated for 4A. The higher rating of the ODU part does not prevent substitution; however, if the application requires the full 2A capacity of the LEMO part, the ODU substitute provides additional margin.

Q: What compliance certifications apply to both parts?

A: Both connectors are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both meet current regulatory requirements for electronic component sourcing.

Q: Are there any backshell or strain relief differences?

A: The LEMO part includes a backshell with chrome plating on brass. The ODU part includes both a backshell and strain relief, with chrome plating over nickel. These features do not affect electrical or mechanical compatibility.
