The datasheet from the schematic symbol does not overwrite the one linked in the footprint.
This bevhavior results in the majority of LCSC part been linked to the wrong datasheet on the PCB.
I meant examples illustrating what you are talking about in the schematic and consequently in the PCB.
Ideally a small dummy project with some parts on the schematic that have then been passed into a PCB to pull in the Footprints.
And a description of the steps you took like did you change the Footprint assignments between placing the symbol in the schematic then converting or updating the PCB?
For example C187516 (in this case not a totally worng datasheet but still a diffrent product):
on the PCB:
on the schematic:
@Xenons,
The Schematic should be considered to be the master document and therefore the BoM from the schematic is the master BoM.
A Footprint on a PCB could be for any one of a number of different devices. For example, think how many totally different devices use the same SOT-23 package.
A Symbol in the schematic references a specific part in a specific package and therefore a specific Footprint. If the part has an LCSC part number then it will also be described by a specific datasheet on the LCSC website.
That's why it isn't beneficial to link the datasheet on the PCB to the footprint as you sad it is used for many parts.
Quick access to the datasheet on the PCB on the otherhand is quite usefull. e.g. looking up details like the sugested layout of dc dc converter.
