FGG.1B.314.CLAD72Z Equivalent & Substitute Parts

Part Overview

The FGG.1B.314.CLAD72Z 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 a wide temperature range of -55°C to 250°C. The product is active and in stock with 999 units available. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the original part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.314.CLAD72Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 14 positions to maintain pin compatibility
• Termination Method: Solder cup termination required for assembly compatibility
• Fastening Mechanism: Push-pull fastening type ensures mating interface compatibility
• Contact Material & Finish: Brass with gold plating maintains electrical performance and corrosion resistance
• Shielding: Shielded configuration required for EMI protection equivalence
• Insert Material: PEEK material ensures mechanical and thermal stability
• Compliance: ROHS3 compliance required for regulatory alignment

The substitute part S21L0C-P14MCC0-720S from ODU meets these core substitution criteria. Both connectors share identical connector type, position count, termination method, fastening type, contact finish, shielding, insert material, and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.314.CLAD72Z and S21L0C-P14MCC0-720S are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ODU substitute part provides a higher current rating of 4A compared to the LEMO original's 2A rating, offering enhanced current capacity for the same connector footprint.

The primary operational difference is the temperature range: the LEMO connector operates from -55°C to 250°C, while the ODU substitute operates from -40°C to 120°C. Selection between these parts depends on the specific application temperature requirements. For applications requiring the full -55°C to 250°C range, the LEMO FGG.1B.314.CLAD72Z is the appropriate choice. For applications within the -40°C to 120°C range, the ODU S21L0C-P14MCC0-720S provides equivalent functionality with increased current capacity.

Both connectors maintain identical core electrical and mechanical specifications: 14-position configuration, solder cup termination, push-pull fastening, shielded design, gold-plated contacts, and PEEK inserts. Cable opening tolerances are compatible within the specified ranges.

Frequently Asked Questions (FAQ)

Q: Can the ODU S21L0C-P14MCC0-720S directly replace the LEMO FGG.1B.314.CLAD72Z in all applications?

A: Direct substitution is valid for applications operating within the -40°C to 120°C temperature range. Applications requiring operation below -40°C or above 120°C must use the LEMO original part to maintain specification compliance.

Q: What is the significance of the current rating difference between these connectors?

A: The ODU substitute provides 4A current rating versus the LEMO original's 2A rating. Both are suitable for applications requiring 2A or less. The higher rating on the ODU part does not affect compatibility but provides additional capacity margin for current-sensitive applications.

Q: Are the cable opening dimensions compatible between these two connectors?

A: Yes. The LEMO connector specifies 0.244" ~ 0.283" (6.20mm ~ 7.20mm) and the ODU connector specifies 0.236" ~ 0.283" (6.00mm ~ 7.20mm). The overlapping range of 0.244" ~ 0.283" ensures compatible cable accommodation for standard applications.

Q: Do both connectors meet the same regulatory compliance standards?

A: Yes. Both the LEMO FGG.1B.314.CLAD72Z and ODU S21L0C-P14MCC0-720S are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

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

A: Both finishes provide corrosion resistance and conductivity. Chrome over nickel offers an additional nickel layer beneath the chrome, potentially providing enhanced durability in certain corrosive environments. For standard applications, both finishes are functionally equivalent.

Q: Are the backshell configurations equivalent?

A: The LEMO part includes a backshell, while the ODU part includes both backshell and strain relief features. The strain relief on the ODU connector provides additional mechanical protection at the cable entry point without affecting electrical compatibility.
