Narrative:

Entered ramp area without proper authority/authorized. Landed runway 1R, received taxi clearance from ground (thought to be -- taxiway K, taxiway a, hold short of taxiway A1, to contact ramp). After turning onto taxiway a past taxiway A5, but short of taxiway A4, finally got hold of ramp control. (They were very busy, frequency congestion.) ramp informed us our clearance limit was hold short of taxiway A5. Factors of this occurrence: 1) unfamiliarity of iad airport, ie, ramp boundaries. 2) frequency congestion on ground and ramp. 3) nighttime. 4) distraction in cockpit, dealing with mechanical issues. 5) fatigue, tiredness of captain and first officer. Long day, late night.
