It appears that Exception 0055123 on an NXP label refers to an internal approval for a deviation in labeling, packaging, or manufacturing logistics. Although your last delivery date for this part was June 2023, the date code 2409 indicates the unit was actually produced in early 2024, meaning NXP likely built it under a special agreement or exception. Such exceptions typically do not affect the electrical or functional specifications of the component; instead, they document that the part was manufactured, labeled, or shipped outside the standard process. In short, the part remains functionally equivalent, but the exception indicates a traceability or documentation deviation that was formally approved within NXP. E-ZPassPA
