LDS-01 Lidar is broken - can I use a YDlidar instead or will Robotis replace it?

One of my small fleet of Turtlebot3 has a Lidar (LDS-01) that isn’t working anymore. Not sure what happened. It used to work. Has anyone used aYDlidar which is much cheaper? Or would Robotis replace the failing Lidar, do you know? Thanks!
