OK... it seams that I am not clear. Thanks for your question.
I begin that have a lot of active electronic part like :
- aop with a single chanel, with two chanels, some are rail to rail, other are low noise
- MAX 232
- NE555
- multiplexer
- various transitors
For resistance I have a smal box for each value (5%). Same for capacitor. And I would like tyo make the same for active componants. I am tinking to have a box for those having an extension number between 0 to 100, 101 to 200... But I am quite surch that will not work properly.
Using the type of the componant is perhaps the good way, but then how to subclassify them ?
I am expecting to be more understandeble

I use four systems for storing parts. Examples follow these descriptions.
1) Those wll known generic parts that are useful in almost any project and for experimentation are sorted into small drawers of a storage cabinet.
2) When i do a project I save all the leftover parts that were purchased for that project in a box labelled with that project name. So each box might have printed circuit boards, housings, ICs, resistors, capacitors in them in case I might want to build some more in the future.
3) The third category is sorted surplus goods. I start with an empty box and as I go through my surplus goods, i put things into the box that seem useful, but I don't sort them. Then, for each box I list all of the part numbers in that box and tape that list to the front of the box. Usually each box contains no more than 40 part numbers. This works well as many surplus items come in reels or large bags, sometimes with documentation, and such things don't fit into storage cabinet drawers.
4) Surface mount RLC. This includes mostly sample and evaluation kits from various manufacturers including resistors, capacitors and inductors. These kits are housed in different forms, like binders, custom boxes, and looseleaf pages, so they end up having their own bookshelf where they are stored, one shelf for resistors, one for capacitors and one for inductors.
Examples:
1) In the first category I have individual drawers for leaded parts (not SMT):
Logic: small scale combinational logic including all ICs such as 74HCxxx etc.
Memory and uP: PICs and memory chips
Linear: simple functions like op amps, comparators, 555, 232interface
Voltage Regulators: 7805, and all other basic types
RF active IC: mmic, mixers
RF filter: crystal filter, ceramic, duplexers, bandpass filters
GP transistors bipolar: PNP, NPN
FET transistors
RF transistors: all types for RF applications, small signal
RF power transistors
Crystals and ceramic resonators
4-40 nuts and bolts
6-32 nuts and bolts
Washers
BNC Coaxial adapters
N type adapters and attenuators
SMA adapters and functional blocks
All values leaded resistors (this is a dump when I don't want to re-sort)
all values leaded capacitors (dump for unsorted parts)
Prestripped jumper wires for plugboards
Short heatshrink
Switches, buttons, potentiometers
Small heatsinks
Opto LEDs and display digits
Leaded resistors, sorted 4 values per drawer, 10% steps
Leaded capacitors, sorted 4 values per drawer
RF chokes
UHF inductors
and many more
2) the second category is a group of small cardboard boxes on my storage shelves in the 'stockroom'. Each labelled with the project name.
3) the third category is also small cardboard boxes with part lists taped to the front and then placed on storage shelves in the 'stockroom'.
There is always a practical limit to how much sorting and organizing you want to do with your parts. For example, I started out with resistors sorted into drawers, but find it faster and easier to use a single "all resistors" drawer where all leaded quarter-watt resistors go after using them in experiments. When I need one I find it not hard to sort through and find something close enough just by scanning for the right colour code. When I need a specific non-generic (like not 10K or 2.2K or 100K which I use a lot) value, then I might refer to a Digikey resistor kit of 1% values that I bought. Eventually, when this kit becomes depleted, I might buy another instead of re-sorting resistors myself.
