Unfortunately the manufacturers rarely standardize. Take SOT23 for instance, there are about 50+ variations on it. Take your parts datasheet, enter the component dimensions into the PCB libraries Library Expert and produce a footprint for your CAD package. The free version should enable you to do t...
