The part fails because of a fatigue fracture in the part of the hinge that's made from Zamac; this fatigue is made much worse if the hinge pin becomes stiff due to corrosion. The steel part of the new type has an anticorrosive coating, but as to whether this will stop the pin from sticking, only time will tell.
If the pin is lubricated with a corrosion-inhibiting grease when the new part is fitted, the repair will likely last the life of the car; if it is assembled dry (as most will be if the job is entusted to a garage), I'd say it's likely to fail again at some point.
I think I might spray some lithium grease in the handle where the hinge is in the hope that some will find its way through to the pin.
