Hello, I can’t find a footprint to add a DC-DC converter traco TEN5-1211 in my project. Has anyone already used such a component?
I hereby certify that I am not simply asking someone else to design a footprint for me.
This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.
As far as I can tell it has 0.1 in pin spacing and 0.6 in row spacing. You should be able to make a footprint with the DIP footprint wizard. Just don’t assign numbers to the unused pins.
Making your own footprints ought to be a routine part of using KiCad. It is easy enough.
Why do you say that? The unused pins can be specified as “unconnected” and no DRC errors should result.
Being able to make symbol and footprint should be a skill all eCAD users should learn.
In this case TRACO have partnered with SamacSys have a footprint

By not numbering the unused pin numbers you don’t even have to make them NC on the schematic, they are not in the symbol.
Is that a symbolic victory?
If I know that a component has X pins (or if I see them on the footprint) then I want to see them somehow on the symbol. If I don’t then I feel the need to go back and check what is going on…
You’ll have a lot of checking for this part. IIRC of 24 pin postions, only 8 are used. And anyway if you forget to use a pin, ERC will tell you. So why clutter the symbol with pins that will terminate in a NC cross?
Numbers are only used to connect symbol pins with footprint pads. Nothing says that they have to be start at 1, be consecutive, or gap-free. In fact they don’t even have to be numbers, but usually they are, for common footprints.
In fact the manufacturer could have labelled them 1-8 but used the numbers to relate to a normal DIP footprint. In OP’s case I would also look at deleting the unused pads.
