Replacement for Allegro A6812

I know this is not MCHP related.  Anyone knows a pin-for-pin compatible replacement for the Allegro A6812, preferably available in SOIC package?  The A6812 is on last time buy status.  Thanks in advance.

    Dude, the data sheet says:
     
    Improved replacements for TL5812x, UCN5812x, and UCQ5812x
     
    I will assume you looked for these parts?  HINT: Look for "5812"
     
    In the meantime, after a quick search in mouser: HV5812

    TI's TL5812 and Allegro's UCN5812 and UCQ5812 are discontinued/obsoleted parts.  The A6812 was replacement for them.  Actually we already replaced the UCN5812 with the A6812 once.  I'm looking into the Supertex's HV5812 status and specs.  Thank you for your help.

    So... it's been a while since the previous post in this thread, but I had the same question and I found an answer: the MAX6921 appears to be a pin-compatible drop-in replacement, and is in-production at the time of wiring this post.  Maxim also makes the MAX6922 series which is functionally similar but has up to 32 outputs, and appears to be pin-compatible with Microchip's own HV518.  And it only took a little more than 10 years to get an answer.
