Identify cracked inductors on logic board (A1502)

There are 2 cracked inductors on my logic board (MB Pro Retina A1502) but I cannot find out their details so that I can order new inductors and replace them on my own.

It would be a great help if someone could help me with.

@giaihai red square is a 22UH-20%-2.4A-0.105OHM (DEM8030C) inductor and yellow square is a 10UH-20%-1.4A-0.17OHM (PST041H)

L7720 10UH-20%-1.4A-0.17OHM + L7710 22UH-20%-2.4A-0.105OHM

L7710 is the bigger one. Usually inductor casings crack, and the inductor is still fine. L7720 is for keyboard backlight and L7710 for LCD backlight, so if the MacBook is dead, replacing these won't solve your problem.
