CAT 303-2381 is listed as a control group. This page is for an enquiry against that specific part number. Availability, item condition and the intended installation need confirmation before an order is accepted.
When comparing an offer, ask for the complete label rather than a cropped photograph showing only 303-2381. Keep any additional markings readable. They give the supplier a record to compare with the unit being sourced, without assuming that a seller title describes the exact controller in the photograph.
If the enquiry comes from an engine or generator-set record, include that identification separately. Do not approve an application solely because a marketplace description mentions the same engine family. Request the evidence behind the proposed match and leave uncertain details open. Other electronic control modules can be considered as separate listings, with their own part references and photographs.
