Different component height.  For example, for 0603, the IPC-7351 
footprints are for the following component heights:

# 0603 (C = 0.85 mm high, L = 0.95 mm high, R = 0.60 mm high)

In this series of passives, some of the footprints are actually the same 
(i.e. CAPCxxxx == INDCxxxx).  The naming convention would seem to call 
out that you should still use CAPC for your caps and INDC for your 
inductors.
