THT IC package naming conventions

The following footprint naming conventions should be used as examples for naming THT IC package footprints.

If you do not find an appropriate convention that matches a particular footprint type, either contact the KiCad library team or try to match a convention set by existing library components.

In the entries below, variable fields are denoted as follows:

- Fixed fields
- Mandatory fields
- Optional fields

Through Hole Packages (DIP)

[PKG]-[Pincount]_[X]x[Y]x[Z]_W[Lead span]_P[Pitch]_[Modifiers]_[Options]

  • PKG - Package name
  • Pincount - Number of (unique) pins
  • X - Major dimension of part on x axis
  • Y - Major dimension of part on y axis
  • Z - Major dimension of part on z axis (Optional)
  • Lead span - Distance between leads
  • Pitch - Lead pitch
  • Modifiers - Modifiers to footprint specifications
  • Options - Extra footprint options (Optional)

Example:

DIP-14_W10.16mm_Clearance

Notes:

  1. Drill size (if specified) must be given in mm

Through Hole Packages (TO)

[PKG]-[Pincount]_[X]x[Y]x[Z]_W[Lead span]_P[Pitch x]x[Pitch y]_[Stagger]_[Modifiers]_[Orientation]_[Options]

  • PKG - Package name
  • Pincount - Number of (unique) pins
  • X - Major dimension of part on x axis (Optional)
  • Y - Major dimension of part on y axis (Optional)
  • Z - Major dimension of part on z axis (Optional)
  • Lead span - Distance between leads (Optional)
  • Pitch x - Lead pitch in x dimension (Optional)
  • Pitch y - Lead pitch in y dimension (if different from x dimension) (Optional)
  • Stagger - Pin staggering options (Optional)
  • Modifiers - Modifiers to footprint specifications (Optional)
  • Orientation - Component orientation (see notes below)
  • Options - Extra footprint options (Optional)

Example:

TO-220-5_Vertical

Notes:

  1. Drill size (if specified) must be given in mm

  2. Orientation can be chosen from:

    • Vertical

    • TabDown

    • TabUp

  3. Stagger can be chosen from:

    • StaggerOdd (odd pins are further from component body)

    • StaggerEven (even pins are further from component body)
