Here is the part that I found 751-VOT8121AM-TCT-ND; VOT8121AM-T
Several key parameters match or are greater (usually okay for most technologies). I advise that you check the datasheet carefully and the other specifications if they need to be specific for your application.
Please review the datasheets to ensure the alternative will work for your application.
