Is there a pin-compatible replacement for PRTR5V0U2X-ES?

Yes, SR05-ES is a pin-compatible replacement based on datasheet review. Other parts like UDT14A05L03 may share the SOT-143 package and pinout but have different electrical characteristics that require careful review.

What risks should I check before replacing PRTR5V0U2X-ES?

When replacing PRTR5V0U2X-ES, critically verify the candidate's junction capacitance, peak pulse power rating, and clamping voltage. Higher capacitance can degrade high-speed signals, while lower power ratings reduce surge protection.
