Is there a pin-compatible replacement for TPA3110D2PWPR?

Currently, no pin-to-pin compatible replacement has been identified. Alternatives like the TPA3136D2PWPR share the same package but have different pinouts, requiring a PCB layout change.

What risks should I check before replacing TPA3110D2PWPR?

Key risks include supply voltage range, output power, and pinout compatibility. The TPA3136D2PWPR has a lower maximum voltage (14.4V vs 26V) and power (10W vs 15W), and is not pin-compatible, necessitating a board redesign and thorough system-level testing.
