I have a part that has 2 variants SOT-23-3 and SOT-23-5. Both have different schematics as one has 3 pins and other 5 pins. Package is also different due to difference in pin count.

The problem is that I can't create a device variant as the pin count is different. I also tried simply creating a second device but then I end up with invalid part name as device names have to be unique and variant name is appended to the device name.

What is the proper way of creating such a part?

Here is a datasheet for the part: https://www.diodes.com/assets/Datasheets/AP2210.pdf

  • \$\begingroup\$ OP - do you mean they have same symbols but different land patterns? If so you can use a single symbol and add package variants, but if you have different symbols, then do as Tom says. Your usage of "different schematics" is a bit unclear. \$\endgroup\$

  • \$\begingroup\$ Maybe this answer by @TomCarpenter in a previous question of mine solves your issue? 1-Create Symbol/Device; 2-Add a variant; 3-Append pads to a given net. \$\endgroup\$

    \$\begingroup\$ The multiple variants to a part is only applicable if all the variants have the same schematic, but different packages. In your case the variants have different schematic symbols, so you have to make two separate parts. You actually are looking two different part numbers with a common datasheet - is the one AP2210K and the other AP2210N. \$\endgroup\$

In Eagle you can define a part with multiple package variants, so long as they have the same schematic symbol(s).

In your case you actually are looking two different part numbers with a common datasheet, the first being the AP2210K and the second the AP2210N.

These two parts have different schematic functionality which means proper way of making such a part is in fact to make two separate parts, one for the AP2210K, and the other for the AP2210N.

  • \$\begingroup\$ The use of the word variant threw me I guess, this makes sense, thanks. \$\endgroup\$
