Hi,
They are probably nearly identical. I guess the 924353-001 could be slightly different because it is for notebooks with discrete graphics, so will have a different heatsink.
The one you need for your notebook is the 934640-001
This is if we are talking about the top cover. Some third party sellers sell only the keyboard (not as one piece with top cover) and most likely they can be placed (with some difficulties} in both the top covers.
