FGA.1B.316.CLAD72Z Equivalent & Substitute Parts

Part Overview

The FGA.1B.316.CLAD72Z is a 16-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 718 units available. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component procurement flexibility while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.1B.316.CLAD72Z is determined by alignment of the following critical parameters:

• Connector Type & Position Count: Plug configuration with 16 male pin positions
• Termination Method: Solder cup termination for direct wire attachment
• Fastening Mechanism: Push-pull coupling system
• Contact Material & Finish: Brass contacts with gold plating on mating surfaces
• Shielding: Shielded design for EMI protection
• Ingress Protection: IP50 dust protection rating
• Compliance: ROHS3 compliance and REACH unaffected status

The substitute part S21LAC-P16MCC0-720S (ODU MINI-SNAP® L series) meets these core functional requirements. Variations in shell size designation, operating temperature range, current rating, and backshell material specifications do not preclude substitution when the primary electrical and mechanical interface parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.316.CLAD72Z and S21LAC-P16MCC0-720S are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for component procurement. The primary distinction lies in operating temperature range and current rating specifications. The LEMO connector supports extended temperature operation from -55°C to 250°C with a 1.5A current rating, while the ODU substitute operates from -40°C to 120°C with a 4A current rating. Selection between these parts depends on application-specific thermal and power requirements. Both connectors share identical core interface parameters: 16-position solder cup termination, push-pull fastening, shielded design, and IP50 ingress protection. Inventory availability should also be considered in procurement decisions, with the ODU part currently showing 1054 units in stock compared to 718 units for the LEMO original.

Frequently Asked Questions (FAQ)

Q: Can the S21LAC-P16MCC0-720S directly replace the FGA.1B.316.CLAD72Z in all applications?

A: Direct replacement is possible when application operating temperatures remain within -40°C to 120°C and current requirements do not exceed 4A. If the original design requires operation below -40°C or above 120°C, the LEMO connector's extended temperature range is necessary.

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

A: Both connectors share 16-position male pin solder cup termination, push-pull coupling, shielded construction, and IP50 protection. Cable opening ranges overlap within 6.20mm to 7.20mm, ensuring mechanical compatibility with standard cable assemblies designed for either connector.

Q: Are there differences in contact finish specifications?

A: Both connectors feature gold-plated mating contacts. The LEMO part specifies 39.4µin (1.00µm) contact finish thickness, while the ODU part does not provide this specification in available documentation.

Q: How do the current ratings affect substitution decisions?

A: The ODU substitute supports higher current capacity at 4A versus the LEMO original at 1.5A. Applications designed for 1.5A operation can use the ODU part without current-related concerns. Applications requiring exactly 1.5A operation should verify that the higher current rating does not introduce thermal or performance variations.

Q: What compliance certifications apply to both parts?

A: Both connectors are ROHS3 compliant and REACH unaffected, meeting EU regulatory requirements for hazardous substance restrictions and chemical safety.
