CAD (KiCad official)

  • Symbol: LM2901DT
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: lm2901dt-etched.step / lm2901dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2901dt.step / lm2901dt.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2901dt.step 195 KB You want the bare part, or you mark your own boards.
lm2901dt-etched.step 1.9 MB You want the part with LM2901DT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 483 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
