A '''field replaceable unit''' ('FRU)<ref name="Newton16p364" /> is a [[circuit board]], part or assembly that can be quickly and easily removed from a [[personal 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|fault isolate]] and replace faulty components.

FRUs are not strictly confined to computers but are also part of many high-end, lower volume consumer and commercial products. For example, in military aviation, electronic components of [[line-replaceable unit]]s, typically known as [[shop-replaceable units]] (SRUs), are repaired at field-service [[backshop]]s, usually by a "remove and replace" repair procedure, with specialized repair performed at centralized depot or by the [[Original equipment manufacturer|OEM]].
