Substitute Part Grouping Explanation

Substitution of the F31H81FS is based on functional equivalence within the RF Tracker product family from Lantronix, Inc. The primary substitute part F33H002B01 shares the same manufacturer and product category classification. Substitution eligibility is determined by the following criteria:

• Manufacturer alignment (Lantronix, Inc.)
• Functional category (RF Tracker)
• Active product status of the substitute
• Compliance certifications (RoHS3 Compliant for substitute)

The F33H002B01 represents the active generation successor within the Tracker product line, designated as TRACKER FOX3-4G-M1-FB, and maintains RF functionality equivalent to the legacy F31H81FS model.
