Can it be replaced directly?

Direct replacement for SL0805200 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review 0805L200SL9AR first; it matches Ih/It and exceeds Vmax by ES data.

Main risk

Pinout, trip curve, and temperature derating are not verified.

Recommended alternatives

0805L200SL9AR is the closest ES match for SL0805200, but pinout and curves need review.
