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.

Great reference for Eagle CAD. Thank you very much
tirtha said
hey is there a way in which i can add the footprints of ICS that arnt available in d list ?
Omkar said
you can create your own library components. See the eagle manual.
Elif said
Where can I find 2N2222 or BC109 in Eagle?
Omkar said
library : Transistors>2N2222
or simply put search for “2N2222″ in search box of “ADD” dialog.
Dave said
Are you trying to say a 1N4148 is a 3 amp Diode?
Omkar said
Opps sorry. Thanks for pointing it out. It should be 1N5408.
BlackCow said
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!
Omi said
Hey … don’t blame EAGLE, search feature in EGLE is extremely useful, only thing beginners don’t know is …. what to search for
. And that’s why I have put up this post

Can you please tell where can i find RMC connectors in Eagle SOftware ?
