EAGLE Library – List of most commonly used electronics components

1 Aug 2015 – Post Reviewed and Updated

EAGLE is preferred by many hobbyists and professionals all over the world. EAGLE comes with huge component library, however to find the desired part in this library is really difficult for beginners. Generally we need resistors, capacitors, voltage regulators, pin headers, connectors, etc when designing any electronic PCB. Following is the list of EAGLE library part names of most commonly used electronics components. This list will be very handy when you have just started using the EAGLE and don’t know which part to select and from which library.

  1. I’m kareem,
    Please i need your help so lack the basic knowledge about electronics… Pls i need your elightment about it and what to do…


  2. Great ! But how do I place 12v (Vcc) in schematic i.e the positive of battery?For gnd there is gnd but what about Vcc?


  3. This is immensely useful, especially for those of us who are new to eagle and don’t know where all the parts are. The search feature is useless in Eagle. Thank you very much!


    • Hey … don’t blame EAGLE, search feature in EGLE is extremely useful, only thing beginners don’t know is …. what to search for :P. And that’s why I have put up this post 😀
