as often hapopens, there are little details nor precise that could gebnerate confusion. The "central" FET is a IRF610B and it is NIT a IRD610, the enclosing case changes, because is a plastic case (TO-220F) and the insulation it is not needed, as instead is specified in the page. This could cause some doubt because the insulation is absent in the box. For the rest, everything seems to be ok, thank you.
