Title: Components to have on hand ?
Post by: ChrisSmolinski on August 19, 2013, 1601 UTC

I thought it might be useful to have a thread about what sorts of parts are good to have on hand, as well as sources for buying them, especially at good prices?

I tend to gravitate to Mouser for most of my general purpose parts, as they have a good selection, and are quick to ship. I also use Jameco from time to time, there are certain parts that they have very good prices on.

You should always have enough for several complete projects on hand!
Mouser, followed by Digikey and Jameco.
Amazon if buying other stuff and I only needed 1 thing or I have some Amazon bucks to burn.  I have found one obscure part I needed on Amazon I could find nowhere else unless I bought a zillion.
pl-259.com for obscure hardware, especially antenna.
toroids.info for umm toroids.
Ebay for all out of production stuff, project boxes, and enameled wire.

Great thread idea!  I wholeheartedly agree with keeping parts on hand.  With minimum orders, shipping costs, and difficulty finding some things, it just makes good sense to me.  Things I "stockpile" that I consider necessary to keep on hand:

Toroids (T50-2, T80-2, T50-6, T80-6) and some ferrite beads-CWS Bytemark, Toroid King
Caps and resistors - all common values - All, Jameco, Dan's Small Parts & Kits
Transistors - 2N3904, 2N3906, 2N2222, 2N3053, 2N3055 - Jameco, Dan's Small Parts & Kits
FETs and JFETs - 2N3819, MPF102, 2N7000, IRF510 - Jameco, Dan's Small Parts & Kits
Op Amps and Linear - TL074, LM555, LM3900, LM741, LM311 - Jameco, Mouser
Linear Audio Chips - TDA2002 (or 2003), LM386 - Mouser
Regulators - LM7812, LM7806, LM7805, LM7905, LM317, 78L05, 78L06, 78L12 - Jameco, Dan's Small Parts & Kits
MISC: T1.75 LEDs (various colors), 22 ga hookup wire, 20 ga magnet wire, many sizes of heat shrink tubing, RCA connectors, SO239s, 3.5" connectors, 2 and 3 pole terminal blocks, several sizes of potentiometers and trimmers... pant pant pant... whew!

And I'm sure I missed some stuff...

I would imagine everyone has a different list, depending on their main interests...
