STUSB4500QTR is a functional alternative USB PD Sink Controller, but requires board layout changes due to a different package.
HUSB238_002DD is a 100W USB Power Delivery (PD) sink controller from Hynetek in a compact DFN-10L package. Finding a direct drop-in replacement is challenging, but functional alternatives like the STUSB4500QTR exist, requiring a board redesign.
No candidates match the DFN-10L package, requiring a PCB redesign.
Functional alternatives exist, but voltage ranges and specific PD protocol features must be re-validated.
The I2C interface is common, but register maps will differ, requiring firmware updates.
No direct, pin-compatible replacement for the HUSB238_002DD is readily available. All viable alternatives require board-level changes.
Use a functional alternative like STMicroelectronics' STUSB4500QTR and redesign the PCB layout to accommodate the different package.
The primary risk is the need for a complete PCB redesign, as no form-fit-function replacements were found.

| Feature / factor | HUSB238_002DD | STUSB4500QTR | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Function | USB PD Sink Controller | USB PD Sink Controller | USB PD Sink Controller — Core function matches. | ||
| Package | DFN-10L (3x3) | QFN-24 EP (4x4) | QFN-24 EP (4x4) — Different package and size, requires PCB redesign. | ||
| Voltage | 3V to 25V | 4.1V to 22V | 4.1V to 22V — Candidate has a narrower operating voltage range. | ||
| Interface | I2C | I2C | I2C — Interface matches, but register maps will differ. |
STMicroelectronics' STUSB4500QTR is a strong functional alternative. It is also a standalone USB PD sink controller but comes in a different package, requiring a PCB redesign.
