gEDA-user: Metric footprints in geda.inc (IPC-7351)

[David Kuehling <dvdkhlng@xxxxxx>]

Hi,

reading through the m4-style footprint definitions, I stumbled into the
metric vs. non-metric footprint definitions
(/usr/share/pcb/m4/geda.inc), i.e. 'RESC1005L', 'RESC1005N', 'CAPC1005L'
etc which are approximately the same as '0402'.

Now I'm just wondering, for parts that the manufacturer claims to be
0402, is there any advantage in choosing one of the more specific metric
footprints?  Also, reading through various datasheets, I cannot find any
capacitors or resistors, for which the last part of the name 'L', 'N' or
'M' is specified, and the geda.inc file doesn't document its meaning
(probably height of the part?).

Just wondering, whether to update one of my designs to (partially) use
the newer footprints.  

Thanks for any help, 
cheers,

David
