You can check the iPad Air schematic/boardview to see if the components are configured the same way. If they are not, the we can clearly see on your picture that there are traces going from the empty pads to the Tristar pads so it should be easy to figure out as [http://wiki.level3.repair/index.php?title=Tristar_Compatibility_List|Tristar IC’s are pretty much compatible across most devices].
Just a quick suggestion when micro-soldering. If you have a camera on your microscope (or use an iPhone directly on the eyepiece), take pictures of the general area before removing IC’s or other components, especially when dealing with logic boards that don’t have full boardviews/schematics. That way, if something gets dislodged by accident, or you can’t remember the proper orientation, you can refer back to your picture.
