Narrative:
On departure and climb out from iah at 4000 ft, we were given a climb by departure to 15000 ft and delete speed restr and intercept J-86. After passing through 5000 ft, we were told by departure to level at 5000 ft because of traffic at 2 O'clock position, less than a mi at 6000 ft. We reached a maximum altitude of 5600 ft before returning to 5000 ft. We saw a turboprop pass off of our right high and pass behind by 1/2 mi. At that time, we were reclred to 15000 ft. TCASII was inoperative.
