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

  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.

  • 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? – WeTech Aug 04 '21 at 10:44
  • No, it is not possible to import .DSN files of OrCAD in to LTspice – MightyBeard007 Aug 04 '21 at 10:46
  • 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? – WeTech Aug 04 '21 at 10:47
  • @Kamran: Your question doesn't mention OrCAD. OrCAD appears to use [PSpice models](https://resources.orcad.com/schematic-capture-circuit-simulation/quick-tutorial-the-new-pspice-model-search) rather than some proprietary format, so you could use the [PSpice models in LTspice.](https://electronics.stackexchange.com/questions/397354/how-can-i-convert-pspice-model-into-ltspice-model/397365) – JRE Aug 04 '21 at 10:51
  • @JRE: I said CAD models. doesn't it contain OrCAD capture? – WeTech Aug 04 '21 at 12:02

    Yes, but it also includes [dozens of other packages.](https://en.wikipedia.org/wiki/Comparison_of_EDA_software) – JRE Aug 04 '21 at 12:07
