Is there a pin-compatible replacement for TPSB476K010R0250?

TPSB476K010R0350 is pin-compatible as it uses the same 3528 (1210) package. However, its higher ESR means it is not a direct functional equivalent for all circuits and requires review.

What risks should I check before replacing TPSB476K010R0250?

Key risks include: 1) Electrical performance: A higher ESR can impact ripple voltage and efficiency. 2) Mechanical fit: Ensure any alternative has the same 3528 (1210) footprint. 3) Thermal performance: Higher ESR can lead to increased self-heating.
