There are very beneficial and comprehensive collections of CAD models provided by Mouser or other websites. Is it possible to use them in LTspice?

  • \$\begingroup\$ provided or collected or referenced. anyway. symbol, footprint, and 3d models are available. \$\endgroup\$

  1. LTspice cannot use 3D models - it has no 3D view.
  2. LTspice cannot use the footprint - has no PCB layout.
  3. LTspice might conceivably be able to use the symbol, but I don't know of any way to import just the drawing.

LTspice needs the spice model, and a mapping between the pins and the model innards.

The CAD models won't provide the spice model, so they aren't of much use in LTspice.

  • \$\begingroup\$ thanks for your response; yes obviously LTspice does not support 3d and footprint models, as you said. but I meant importing the OrCAD capture schematics models into LTspice. is it possible? \$\endgroup\$

  • \$\begingroup\$ No, it is not possible to import .DSN files of OrCAD in to LTspice \$\endgroup\$ Commented Aug 4, 2021 at 10:46
  • \$\begingroup\$ by the way, are the OrCAD capture schematic models available on mouser or ultra librarian? if not, is there any straightforward and comprehensive website containing spice models? \$\endgroup\$

  • \$\begingroup\$ @Kamran: Your question doesn't mention OrCAD. OrCAD appears to use PSpice models rather than some proprietary format, so you could use the PSpice models in LTspice. \$\endgroup\$
