Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB7216/KDX is determined by the following critical parameters:

• Manufacturer: Microchip Technology (same manufacturer ensures design compatibility and firmware support)
• Package / Case: 100-VFQFN Exposed Pad (identical footprint and pin configuration required for PCB compatibility)
• Supplier Device Package: 100-VQFN (12x12) (ensures mechanical and electrical pin alignment)
• Function: Hub Controller (maintains system-level functionality)
• Protocol: USB (preserves communication protocol)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification (regulatory alignment)

The USB7216C/KDX qualifies as a substitute part based on matching manufacturer, identical package specifications, equivalent hub controller function, and aligned compliance certifications. The substitute part extends interface capabilities and supports active product status, providing enhanced availability and long-term supply security.
