Which replacement charger port for sm-s903vl? Cuz theres G900v? Etc

I tried to look for a replacement charger port for a Samsung galaxy s5 straight talk the SM-S903VL. It comes up with a few different one's like the G900V or G900R7 or G900A or G900M! So without taking the phone apart, is there another way to find out which one is the correct one to get for replacement? Or would it be better to take to a day phone repair store?
