I had just completed administering a line check to one of our capts on the previous 2 legs. I was flying the last leg. I copied the clearance and when he returned to the aircraft I had not yet selected the SID from the charts. My first officer checked the clearance, selected the SID and we discussed it. The WX conditions included winds gusting to 30 KTS and low level wind shear which was reported by several aircraft. Since my first officer had operated out of this airport for almost 2 yrs he was very familiar with it. The altitude alerter was set to 3000' and we made every effort to stay south of a radial which is depicted on the chart as a northern boundary for the turn. Having done everything correctly we were both surprised when departure said we were supposed to level off at 2000, not 3000'. Our clearance was for the canal 3 departure and we had looked up the mdw 3 departure. No traffic conflict existed, but this will surely teach me to make absolutely certain that the correct SID is being referenced and not to assume that the other pilot, due to his past experience, has pulled the correct chart. I would suggest a better system would be not to use the same number (ie, 3) on 2 departures which are so similar.

Title: PULLED WRONG SID CHART FOR MDW RESULTING IN CLIMBING TO 3000 VERSUS 2000'.
Narrative: I HAD JUST COMPLETED ADMINISTERING A LINE CHK TO ONE OF OUR CAPTS ON THE PREVIOUS 2 LEGS. I WAS FLYING THE LAST LEG. I COPIED THE CLRNC AND WHEN HE RETURNED TO THE ACFT I HAD NOT YET SELECTED THE SID FROM THE CHARTS. MY F/O CHKED THE CLRNC, SELECTED THE SID AND WE DISCUSSED IT. THE WX CONDITIONS INCLUDED WINDS GUSTING TO 30 KTS AND LOW LEVEL WIND SHEAR WHICH WAS RPTED BY SEVERAL ACFT. SINCE MY F/O HAD OPERATED OUT OF THIS ARPT FOR ALMOST 2 YRS HE WAS VERY FAMILIAR WITH IT. THE ALT ALERTER WAS SET TO 3000' AND WE MADE EVERY EFFORT TO STAY S OF A RADIAL WHICH IS DEPICTED ON THE CHART AS A NORTHERN BOUNDARY FOR THE TURN. HAVING DONE EVERYTHING CORRECTLY WE WERE BOTH SURPRISED WHEN DEP SAID WE WERE SUPPOSED TO LEVEL OFF AT 2000, NOT 3000'. OUR CLRNC WAS FOR THE CANAL 3 DEP AND WE HAD LOOKED UP THE MDW 3 DEP. NO TFC CONFLICT EXISTED, BUT THIS WILL SURELY TEACH ME TO MAKE ABSOLUTELY CERTAIN THAT THE CORRECT SID IS BEING REFERENCED AND NOT TO ASSUME THAT THE OTHER PLT, DUE TO HIS PAST EXPERIENCE, HAS PULLED THE CORRECT CHART. I WOULD SUGGEST A BETTER SYS WOULD BE NOT TO USE THE SAME NUMBER (IE, 3) ON 2 DEPS WHICH ARE SO SIMILAR.
