Is there a pin-compatible replacement for PESD5V0S1BB-ES?

Several candidates like PESD5V0V1BB-N and TPPESD5V0S1BB share the same SOD-523 package and 2-pin layout, making them form-fit compatible. However, electrical parameters like power rating and capacitance differ, requiring careful review before use.

What risks should I check before replacing PESD5V0S1BB-ES?

Key risks include mismatched directionality (use only bi-directional parts), lower peak pulse power handling, higher junction capacitance affecting high-speed signals, and a higher clamping voltage which could offer less protection.
