Is there a pin-compatible replacement for PESD5V0S1BA?

Yes, several parts like PESD5V0L1BA share the same SOD-323 package and 2-pin layout. However, you must verify key electrical parameters like peak current and clamping voltage before substitution.

What risks should I check before replacing PESD5V0S1BA?

Key risks include mismatched polarity (uni-directional vs. bi-directional), incorrect voltage rating, and lower peak pulse current or power ratings, which could lead to inadequate circuit protection.
