Quoted from stvns78:The DS1811-10 reset generator is obsolete as it seems. Would the DS1811-10+T&R be fine. DigiKey says its a direct sub.

FWIW - I got my MCP130-460DI/TO (direct substitute) on Amazon last year for about $5 incl. shipping. Worked great so I got a second one for my anti-thunk driver board modification.
