There's an array of 10 MELF resistors arranged as a voltage divider for high DC voltage sensing. All of the resistors are 400k (1/4W or 1/2W not sure). One of them is open. I'm trying to find the same replacement in Mouser/Digikey but I don't see them available. The closest one I saw was 402k but they are non-stocked. What do you suggest in this case? Using another package? The board is pretty delicate, that's why I'm trying to find the same replacement in order to avoid doing some ugly tweaking.
