Substitute Part Grouping Explanation

Substitute parts for the USB5926C/KD are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical voltage supply ranges (1.08V – 1.32V and 3V – 3.6V), operating temperature range (0°C to 70°C), and support the same USB standards (USB 2.0 and USB 3.1).

Functional Equivalence: All parts perform the hub controller function with identical interface support (I2C, SMBus, SPI, UART).

Mechanical Compatibility: All parts use the same 100-VQFN (12x12) Exposed Pad package, ensuring PCB layout and thermal management compatibility.

Compliance Alignment: All parts maintain ROHS3 compliance and MSL 3 moisture sensitivity rating, meeting the same environmental and regulatory requirements.

The substitute parts USB5906C/KD and USB5916C/KD are parametrically equivalent to USB5926C/KD across all specified electrical, functional, and mechanical parameters.
