A '''field-replaceable unit''' ('''FRU''')<ref name=Newton16p364/> is a [[printed circuit board]], part, or assembly that can be quickly and easily removed from a [[computer]] or other piece of electronic equipment, and replaced by the user or a technician without having to send the entire product or system to a repair facility. FRUs allow a technician lacking in-depth product knowledge to [[fault detection and isolation|isolate faults]] and replace faulty components. The granularity of FRUs in a system impacts [[total cost of ownership]] and support, including the costs of stocking [[spare part]]s, where spares are deployed to meet repair time goals, how diagnostic tools are designed and implemented, levels of training for field personnel, whether end-users can do their own FRU replacement, etc.
