From IPC-7351, a nominal condition for a CAPC4520X168N footprint (4.5
mm x 2.03mm x 1.68 mm) you'd have
pad X = 2.30 mm
pad Y = 1.20 mm
pad spacing = 4.30 mm
If you orient the part with pin 1 on the left and 2 on the right, pad
X is the vertical pad dimension and pad Y is the horizontal dimension.
pad spacing is the center-to-center spacing.
For CAPC4620X203N (4.57 mm x 2.03 mm x 2.03 mm) they give
X = 2.50, Y = 1.30, C = 4.30mm
You can download the land pattern viewer from www.pcblibraries.com.
It's a good source for figuring out good sizes.
Hope this helps.
