It doesn't even mater if it's a different director and/or concept. If the performer has played the role on Broadway before, they are ineligible for the Tony in future productions (in the same role).
Case in point: Lonette McKee in Show Boat. Her second production, directed by Hal Prince, was magnificent, and she could have easily won for playing Julie (even beating out Glenn Close, IMO), but she had already been nominated in the Michael Kahn production back in 1983. A different staging of Show Boat.
