Key Parameters

Substitute Part Grouping Explanation

Substitution of the F31H03FS is based on the following criteria derived from provided parameters:

Primary Substitution Basis:

• Manufacturer alignment: Both components manufactured by Lantronix, Inc.
• Functional category: Both classified as RF tracker modules
• Product lineage: F33H002B01 represents the active generation successor within the tracker product family
• Detailed description match: Both designated as RF applications

Substitution Logic: The F33H002B01 (TRACKER FOX3-4G-M1-FB) is identified as the equivalent substitute for the obsolete F31H03FS based on functional RF tracker classification and manufacturer continuity. The F33H002B01 maintains active product status with current manufacturing support and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and System Updates: The F33H002B01 is the designated active substitute for the obsolete F31H03FS. This component maintains manufacturer continuity with Lantronix, Inc., and is certified ROHS3 compliant, meeting current environmental and regulatory standards. The F33H002B01 carries active product status with ongoing manufacturing support and documented inventory availability.

For Legacy System Maintenance: Original F31H03FS units remain available in inventory (1062 pieces) for applications requiring exact part matching. However, transition to the F33H002B01 is recommended for new procurement cycles to ensure long-term supply chain stability and regulatory compliance.

Compliance Considerations: The F33H002B01 provides explicit ROHS3 compliance certification, whereas the F31H03FS RoHS status is not documented. This distinction is relevant for applications subject to environmental regulations or customer compliance requirements.

Frequently Asked Questions (FAQ)
