Meaning – The term field replaceable unit or FRU is an assembly that is replaced in its entirety when any one component fails. In some cases, a field-replaceable unit may contain other field replaceable units.

It is generally a printed circuit board or an assembly, that can be quickly removed or replaced within a computer or other 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 isolate faults and replace faulty components.

Example of usage“He was glad that he had some field replacement units available for his computer, as he did not have the technical skills to perform an in-depth repair and there were no service centers nearby.”
