There is now a collection of footprints on gedasymbols.org based on the vertical, horizontal, = and screw terminals discussed above in the thread.

i.e.
http://www.gedas= ymbols.org/user/erich_heinzle/kicad/footprints/w_conn_screw.mod/mstba_2_5_3= -g-5_08.fp

This appears to be 2= 00 mil spaced, i.e. 5.08mm pitch, which I think is what was needed.

SOD323 is about the same size as 0603 and has polarity; in my footpr= int
collection I have 2 variants, one with smaller pads (downloaded from
somewhere, possibly John Luciani's site)[1] and the one in pcblib-newli= b
with larger pads and a slightly larger outline, but the distance between pads is exactly the same as for 0603

The one with smaller pads makes it easier to route a trace between them, and might help getting a compact board when designing for automated
assembly, thile the other one should be easier to hand solder.
