Here follows a list of the most commonly used parts in a hacking/tinkering environment. If you don't know what you need, you can most probably start with something from the list.
I _will_ make mistakes so please correct me. Since this list is intended for beginners, I will prefer through hole/DIP than SMD. Specs come from the datasheets, I will try to have as much info on each part as possible while still keeping it compact

opamps (specs vary with temp/supply etc. These are ballpark figures)
LM358/LM2904 (single supply, 0.7Mhz, 20mA out, out range Gnd + 5mV-> +Vcc - 2)
TL071-TL074 (single/dual supply, 3Mhz, out range -Vcc + 1.5V -> +Vcc - 1.5V)

TS922 (high out current, single/dual supply, rail to rail, 4MHz, 80mA out, out range -Vcc + 0.1V -> +Vcc -0.1V)
comparators
LM393 (2x, single/dual supply, 1.5Mhz)
LM339 (4x, single/dual supply, 1.5Mhz)
LM319 (2x, single/dual supply, 6Mhz)
To be continued with as many common parts as I can. Some suggestions on models of optocouplers, mosfet drivers, P-mosfets and logic level N-Mosfets are welcome

Hello Everyone,
I'm in the process of buying parts to fill my workbench drawers with components in order to have them available for the next prototype idea that I want to build in 5-10 minutes. Problem is, when I search for parts there are so many choices that I am not really sure which one would fit the bill. I need some suggestions on the most common building parts that someone should have on the workbench at all times - meaning, specific part numbers. Although I already found bjt (bc548)/mosfet (2n7000)/diodes (1n4148) and some others, I would really like to hear what everyone has to say.
Ideally I would like to have suggestions for opamps (standard/rail2rail), different types of diodes, comparators, signal/power transistors (fet & bjt), voltage references, voltage regulators etc, as well as more specialty items like the 555 which although has a more specific use, it is "mandatory" on a workbench.
If we come up with enough info, I will edit this post to add a nice list so everyone can have it as a reference
