Obsolescence isn't that important because the big surplus warehouses around the world still stock them. Try Octopart or your other favorite inquiry tool to see stock in many places around the world.

BU931P was designed for the same application (automotive electronic ignition) and all the specs I compared were equal to, or better than, the BU931T. It seems the P version is scheduled to go obsolete too but it is in stock at Mouser. Elecraft is still selling and repairing the KPA500. It would be interesting to know if Q5 was changed to a different type or if they have a lifetime stock of the BU931T.
