Is there a pin-compatible replacement for H24VND3BA?

Yes, parts like ESD24VD3BQ and PESD1IVN27-A-ES are available in the same SOD-323 package and are strong candidates for being pin-compatible, as they are 2-pin symmetrical devices.

What risks should I check before replacing H24VND3BA?

Before replacing, verify the substitute's peak pulse power (Ppp), peak pulse current (Ipp), and junction capacitance (Cj). A part with lower power/current ratings is a downgrade, and a very different capacitance can affect signal integrity.
