Black piping suggests that the soldier might be wearing a commutation jacket, styles of uniform jackets that private soldiers purchased that were made to regulation cut* and were reimbursed by the government for their purchase. These were very common early war, but by 1862 the majority of Confederate soldiers received their uniforms from a depot system (Richmond for the Army of Northern Virginia, Columbus and Atlanta for the Army of Tennessee, Shreveport and Houston for Trans-Mississippi Department troops, etc.)
That said, the cut is reminiscent of late war style jacket (resembles a type III), and the piping is just there because the jacket was made in material on hand. As for what type of soldier, I have no idea. Even if the jacket were marked in the regulation branch of color (blue for infantry, red for artillery, yellow for cavalry, green for medical, buff for staff and generals, etc.), there are many cases of soldiers being issued what on hand at the depot (there are cases of artillerymen in the Army of Tennessee wearing blue trimmed Columbus Depot Jackets, while some Arkansas infantry regiments of Buford's Brigade in Pemberton's Army received red trimmed jackets, etc.) and the result being a mix match of colors and wrong trim being worn by the wrong troops styles. After 1862, the Richmond depot generally dropped colored trim, so this was less problematic in Lee's Army.
As for it being a commutation jacket: This is a good example of a private in Jackson's Valley Army wearing one.
*Again, cut did not always meet official Confederate regulation.
