I would like to show you how I organize the spare parts. I have an updated list of all components (IC’s, diodes and transistors) and keep them in small boxes which are labeled (see attached image).
This list (excel file) has several pages, one for each part type: uC, opamp, regulators, etc.
Each line corresponds to a single part and has all the information needed: exact model number, quantity, SMD or through-hole indication, small description with the most important features, link to data sheet and finally the box number where it is stored.
This list is very useful when developing a new project. In this way I always know what components I have or not and the respective packages in case I’m designing the PCB.
