CAT 262-2879 is associated with C9, 324D and 330D references in public parts listings. Treat those references as leads for checking the application. The original label and equipment record still decide whether the proposed controller is suitable.
Pay close attention to the mounting holes and connector lock. Photograph the controller straight on, then show the case edge and fixing points. These views answer a different question from the part number: can the offered housing and plug be compared with the unit in the excavator?
If the listing describes a programming or condition detail, ask the supplier to confirm it for the actual unit offered. Send the machine serial information, engine record, quantity and destination with the 262-2879 request. See the CAT product range for separate part searches rather than treating a similar number as a substitute.
