Is there a pin-compatible replacement for LESD5D5.0CT1G(UMW)?

Yes, several alternatives exist in the same SOD-523 package. However, they are not electrically identical. For example, H5VND5B is pin-compatible but has a lower peak power rating, which must be verified.

What risks should I check before replacing LESD5D5.0CT1G(UMW)?

Key risks include mismatched peak pulse power (Ppk), junction capacitance (Cj), and breakdown voltage (Vbr). A lower power rating can lead to device failure. Higher capacitance can degrade high-speed signals.
