It's a standard package used by hundreds if not thousands of different transistors and ICs. The only way to identify them without a schematic is by the number on the body so you will have to be sure what it is.
Unfortunately, with such small space to mark the number there is inevitably a lot of duplicaton of numbers, often between completely different types of component. Take a very close look at the markings, including any smaller numbers or letters which may not be in line with the others and let us know for sure what they are. From the connections we can see in the photograph and reference tables we might be able to identify them for you.
