ipad Nand Ic compatible

can someone confirm if nand swap is compatible
with iphone 5 we can use in ipad mini 1 gen
I have been able to format and change serial on iphone 5 nand
then restore in ipad mini, but having problem with itunes restore
(waiting for ipad ). I have many cases of this happening
same with iphone 5S to ipad air or do i need to order same model nand ic?
has anyone tried this yet?
Thank you
