Is there a pin-compatible replacement for BSMD0805-020-24V?

Yes, BSMD0805-020-33V is considered a pin-compatible upgrade. It has the same 0805 package, pinout, and key electrical ratings. SMD0805-020C-33V is also a pin-compatible alternative from another vendor.

What risks should I check before replacing BSMD0805-020-24V?

Before replacing, confirm the hold current (Ih) and trip current (It) match your design's protection requirements. While higher voltage is safe, ensure the replacement's resistance and time-to-trip characteristics are acceptable for your application.
