Narrative:

On departure from runway 24; the SID calls for you to fly the runway heading until 1500 ft MSL with a right turn to 280 degrees until the 4.5 DME fix and then climb to 2000 ft MSL. The altitude selector was improperly set to the 2000 ft altitude rather than the initial 1500 ft required by the SID. When I turned to a heading of 280 degrees; I climbed to 1860 ft before ATC called my attention to the error. The DME distance; at the time of the climb; was approximately 3.6 DME rather than the 4.5 DME required by the SID. Proper use of either the altitude selector to the initial altitude; required by the SID; or a departure made in the mode select navigation and VNAV with the FMS departure linked from the database would have prevented the deviation. At 1500 ft MSL; just prior to the turn to 280 degrees; we encountered a TCAS TA (amber) alert that I did look outside to attempt to acquire. This may have been a distraction that prompted the premature climb.

Title: A C750 ON THE TEB 5 DEP OUT OF TEB CLBED THROUGH THE 1500 FT RESTR TO 1860 FT.

Narrative: ON DEP FROM RWY 24; THE SID CALLS FOR YOU TO FLY THE RWY HDG UNTIL 1500 FT MSL WITH A R TURN TO 280 DEGS UNTIL THE 4.5 DME FIX AND THEN CLB TO 2000 FT MSL. THE ALT SELECTOR WAS IMPROPERLY SET TO THE 2000 FT ALT RATHER THAN THE INITIAL 1500 FT REQUIRED BY THE SID. WHEN I TURNED TO A HDG OF 280 DEGS; I CLBED TO 1860 FT BEFORE ATC CALLED MY ATTN TO THE ERROR. THE DME DISTANCE; AT THE TIME OF THE CLB; WAS APPROX 3.6 DME RATHER THAN THE 4.5 DME REQUIRED BY THE SID. PROPER USE OF EITHER THE ALT SELECTOR TO THE INITIAL ALT; REQUIRED BY THE SID; OR A DEP MADE IN THE MODE SELECT NAV AND VNAV WITH THE FMS DEP LINKED FROM THE DATABASE WOULD HAVE PREVENTED THE DEV. AT 1500 FT MSL; JUST PRIOR TO THE TURN TO 280 DEGS; WE ENCOUNTERED A TCAS TA (AMBER) ALERT THAT I DID LOOK OUTSIDE TO ATTEMPT TO ACQUIRE. THIS MAY HAVE BEEN A DISTR THAT PROMPTED THE PREMATURE CLB.
