I meant that the footprints that came with gEDA are missing a lot of
common SMD components. Your list is very extensive. It has several
footprints that I've unfortunately already created, such as D2PAK and
the 2010 chip resistor. On some of the parts I needed, it was unclear
as whether they matched anything standard, for example, the 2505 photo
coupler IC. The thing's wider than an SOIC narrow and narrower than a
wide but didn't quite seem to match the medium either.
The 6N138 is close to the 2505-2. The lead span (L1) on the
2505-2 is 9.6mm and the pin spacing is 2.54mm. The lead span
on the 6N138 is 10.54mm and the pin spacing is 2.54mm.
You can read the pin spacing, lead span and number of pins
from the footprint name ---
OPTO-254P-1054L1-8N__Fairchild_6N138
See the naming specification on my gEDA page for more information.
