EU sometimes portrayed him as Mandalorian (then, when he turned out to be a clone, Jango as Mandalorian) but Lucas saw the EU as a separate thing - to be drawn on occasionally when convenient, but otherwise ignored.
Thus, in an early TCW episode (Season 2?) a Mandalorian says:
"Jango Fett was a common bounty hunter. How he acquired that armour is beyond me."
