The Samsung GH98-45420A ASSY SIM TRAY-ZA V2 is a replacement tray for holding a SIM or SD card in a compatible Galaxy Tab S6 Lite tablet. Its practical role is simple: it provides the card-holding part for the tablet.
The tray is grey and is listed for the LTE versions SM-P615 and SM-P619. This makes it a specifically identified spare part for those models, rather than a universal tablet tray.
Use this part when replacing the matching SIM/SD card holder. The listing identifies it by Samsung part number GH98-45420A and the manufacturer description ASSY SIM TRAY-ZA V2.
