Narrative:

We were a bit rushed as aircraft was towed in 24 min before scheduled departure. We were filed IDU4 departure jct transition. When we received the pre departure clearance it had no SID in the remarks section; but under revised segment I read jct; which was already our cleared fix on the SID. Even though it was listed under 'revised segment' I am accustomed to seeing one of our existing fixes in this space; something to do with ATC functions sometimes causes this. Switching to departure frequency; [ATC] kept trying to clear us to a fix not on our legs page. It was then discovered the revised segment was actually an entire different SID; which is named the same as our previous SID's transition; it said JCT7 instead of jct; and we never noticed this change. Departure then vectored us out and gave us clearance to a point downline on our originally filed route.

Title: A B767-300 Pilot reported a SID routing change in the PDC went unnoticed and a track deviation resulted.

Narrative: We were a bit rushed as aircraft was towed in 24 min before scheduled departure. We were filed IDU4 departure JCT transition. When we received the PDC it had no SID in the REMARKS section; but under REVISED SEGMENT I read JCT; which was already our cleared fix on the SID. Even though it was listed under 'revised segment' I am accustomed to seeing one of our existing fixes in this space; something to do with ATC functions sometimes causes this. Switching to departure frequency; [ATC] kept trying to clear us to a fix not on our legs page. It was then discovered the revised segment was actually an entire different SID; which is named the same as our previous SID's transition; it said JCT7 instead of JCT; and we never noticed this change. Departure then vectored us out and gave us clearance to a point downline on our originally filed route.
