The SOT23 Land Pattern Footprint Name has been corrected in V2019.02.

Hi Tom,

I'm also seeing the pin number disappear from the SOT23 parts in v2019.
This means that the same land pattern is called for either 3, 5 or 6 pin parts with the same geometry.

I cannot use this approach as my CAD library wants to over-write the files (as they are all the same name) and my CAD package will fail as there is the same land pattern for 3/5/6 pin parts...

Reverting back to v2018 until this is corrected.

The Land Pattern Footprint Naming convention was updated in Library Expert V2017.

Look in this folder on your computer - 
C:\Program Files (x86)\PCB Libraries\Library Expert 2019\Documents

You will see these very important documents - 
  • Library Expert Land Pattern Naming Convention.pdf
  • Library Expert Surface Mount Families.pdf
  • Library Expert Through-hole Families.pdf
  • Library Expert Solder Joint Goal Tables.xlsx
  • PCB_Library_Expert_SMD_Reference_Calculator.zip

Hi Tom,

Thanks for the quick reply. Just so that I am clear, SOT23-3P50 now becomes SOT23-P50? The "3" before the P50 goes away? The new footprint name I am getting is "SOT23-P65_210X110L32X32" and it does not have the pin number in it at all. How do I tell if it is a 3P vs 6P vs 8P?

Is this change new to 2019.02?

The new IPC-7351 Land Pattern Naming Convention pushed the Pin Qty from the end of the Footprint Name to the beginning. 

So, SOT23-3 or SOT23-5 or SOT23-6 or SOT23-8 is the common pin qty of the SOT23. 

The P95, P65 & P50 is the Pin Pitch - 0.95 mm or 0.65 mm or 0.50 mm pitch.

Is there a footprint naming convention change for SOT23 packages? 

When I update any existing package in my library, it asks me to update the footprint name when saving back to library and changes the name. 

For example, SOT23-3P50_160X90L22X22 changes to SOT23-P50_160X90L22X22. 

I see that with every SOT23 package in my library (20+ items). 

I have not tried others.
