Is there a pin-compatible replacement for ESD9B5VD?

Yes, several parts like TPESD9B5.0ST5G and WE05D9-B use the same SOD-923 package and are considered pin-compatible. However, you must always verify key electrical parameters before substitution.

What risks should I check before replacing ESD9B5VD?

Before replacing ESD9B5VD, you must verify the replacement is bi-directional. Also, ensure its clamping voltage is less than or equal to 10V and its peak pulse power rating is at least 60W to maintain the same level of protection.
