I noticed Through-hole Naming Convention doesn't contain an N suffix.
However Surface Mount contains the suffix 'N' when using Nominal Density Level in Options.
Can you explain this point? |

The 3-Tier library system only pertains to Surface Mount footprints.
 There is only 1-Tier for through-hole and we refer to it as 'Proportional' pad stacks where the pad diameter is 1.5 times the hole diameter.  |

Also, when a Surface Mount footprint uses the Mfr. Recommended Pattern or the footprint is non-standard, there is no Density Level for these footprints as they are the mfr. recommended patterns.

So the mentioned statement means there is no suffix N in below cases also through hole, is this correct?
"When a Surface Mount footprint uses the Mfr. Recommended Pattern or the footprint is non-standard, there is no Density Level for these footprints as they are the mfr. recommended patterns." |
