A raytheon beechcraft 1900 did an air return to ZZZ because the anti-skid fail annunciator illuminated. Once on the ground; we troubleshot the problem and decided to replace the anti-skid control box. It was sent up from ZZZ1. When I received the part; I noticed the paperwork with it didn't look like the paperwork we usually get with parts. It did have a lot of the information that should be there; but raised concern to me. I brought the paperwork to my supervisor; mr Y; who also noticed it didn't look like the normal paperwork. He attempted to contact management in ZZZ1. I was told he had talked to mr Z; and that because the part didn't come from one of our usual vendors [suppliers]; that was why it didn't look normal; and that it was ok and that it was ok to install the part. I installed the part; ops checked the anti-skid system and signed-off all required paperwork. The aircraft was returned to service.a month later I was informed that the paperwork in question was not sufficient to install the part. I was instructed to immediately remove the part [anti-skid control box] and install one with approved paperwork. I did. Suggest training on identifying and approving parts and associated paperwork [that is] ok to use on aircraft.
