Differences from BC19
Although the BC08 is identical to the BC19, both visually and in terms of the screw mounting holes, the two belt clips differ. The U-shaped bracket with which the belt clip is affixed to the radio is higher in the case of the B19. Therefore, the BC19 can be used for radios that have larger batteries with a higher capacity.
The BC08 is on the other hand better suited to attach the radio to materials such as pants, "normal" belts or pockets. For thicker belts or other carrying devices, the BC19 is instead the better choice.
