The design were based on the middle coaches of the PNR 8000 class and 8100 class DMUs retaining the same specifications. The 8300 class coaches, along with the 8000 and 8100 DMUs are all given the designation K3 while in Indonesia.

Interior
There are three double-leaf sliding doors per side and longitudinal seats are used. The interior design is the same as the middle cars of the 8000 and 8100 DMUs. The middle coach has a control room where the doors, lighting, and passenger announcements are controlled. Each car has closed-circuit television cameras installed.
