Jellybean list

[Phaedrus]

In light of the discussion earlier about what is a jellybean, I wonder if people could post what ICs they consider to be jellybean parts

Some of the ones we got in that thread:

Op-amps:
LM324
LM358
TL072

Comparators:
LM393
LM339

Timers:
NE555

Transistors:
2n2222
BC548
PN2907
2N3904
2N3906

Diodes:
1N4148
1N914
1N400x
1N5817
1N5819

Regulators:
LM317
78xx
MC34063

Voltage reference:
TL431

Logic:
74HC series

[c4757p]

Transistors:
PN2907
2N3904
2N3906
plus the MMBT version of all of them

Diodes:
1N4148 / 1N914
1N400x
1N5817-19

Voltage reference/shunt reg:
TL431

You could make a case for LM337/LM79xx and the 741 op amp, but they're not really all that common anymore. Same with most of the 4000 series, except a select few (like the 4051/2/3 analog muxes).

TL072?

There have been quite a few similar lists compiled on the forum - this is a recent one.

It was also suggested in that thread that the completed 'jellybean' list could be added to the wiki - doesn't seem to have happened, though. Maybe the wiki needs more love...

Op-amps:
LM324
LM358
TL072

I would also include at least the OP-07 for precision use since there are so many sources for it now and it is cheap.

Transistors:
2n2222
BC548
PN2907
2N3904
2N3906

I have replaced the 2N2222 and 2N2907 with the 2N4401 and 2N4403 which can also in almost all cases replace the 2N3904 and 2N3906 as well.
I would include a complementary pair in TO-225 packages for those times when a TO-92 will not cut it.

2N7000 (TO-92 N-Channel MOSFET)
2N3055
D44H11 and D45H11

Diodes:
1N4148
1N914
1N400x
1N5817
1N5819

I do not think there is any reason to have both the 1N914 and 1N4148.
I would include the 1N270 or a small signal schottky.  They make great baker clamps, protection diodes, and detectors.
I would include the 1N4937 as a general purpose fast recovery rectifier.
In general a higher voltage diode in the same series can replace all of the lower voltage ones and usually does not cost any more so there is no reason to include the 1N5817.

Regulators:
LM317
78xx
MC34063

LM317LZ (makes a good instant current source/sink)
LM337
78Lxx
79xx
79Lxx

[con-f-use]

Temperature Sensors:
TC1047
TMP35 / TMP36 / LM35
TC77 (digital)

Strange, I wouln't consider those as jelly bean, it's more common to use (at least here):

bc337, bc547, bc556; for more power bd139 and bd140; 2n7002 as mosfet

And just a bit more than a decade back, we were used to use old TESLA (communistic factory for el. parts), some have still full draws with those:
ksy21, kc507, kf507, kd502, etc...

I keep a stock of high beta transistors like the 2N5087 and 2N5088 around for when general purpose ones will not do but since their application is limited, I did not mention them.  For similar reasons I might leave the BC series intended for audio out as well.

Similarly I try to keep saturated switching or RF transistors like the MPSH10 and MPSH81 around.

PN2222/2907 and 2N3904/6 are very common here.

Why are people calling cheap and readily available parts jellybeans? Hmm outside US jellybeans are hard to find, and if you do, they cost a fortune!

They are. Readily available in the uk  and syes they are expensive

[NiHaoMike]

The 3842/3843 and equivalents are common in switching power supplies.

I've been looking for a small-signal jellybean p-channel mosfet without luck. I've been using a ZVP4424A which works but it's a bit expensive (ok, I'm a cheapskate!). So I have come here, metaphorical cap in hand, hoping that someone can suggest a better alternative or help me to improve my search abilities so that I can find it myself (teach a man to fish and all that). One of the attractions for me of Jellybean parts apart from price is the long lifetimes that they endure. I'm looking forward to building 555 circuits with my great-grandchildren!!

I have looked over the more obvious threads here and via google, so apologies in advance if this has already been answered and I missed it somehow.

I need to switch only a few mA by a 3.3v logic level from a MCU, for voltage measurement of a battery. The mosfet is used to avoid the (tiny) losses involved in a more straightforward resistor divider. Essentially I want to make the circuit in the attachment (from original design here: http://jeelabs.org/2013/05/18/zero-power-measurement-part-2/)

My ideal mosfet would be:
Low leakage when 'off' (is this what is referred to as Gate-Body Leakage?)
Cheap
Readily available until the end of time
Available in both through hole and surface mount

From my other research on the web I've looked at these candidates:
BSS84 - smt only
FDN338 - smt and can't find it on sale!!

So is there a part that fits all my needs? The leakage needs to be below ~200-300nA because otherwise I may as well use a resistor divider.

I've blogged about the application for this circuit and this question here: http://l0l.org.uk/wireless-sensors-overview/

Many thanks in advance.

I might add SD103 as the schotkey small diode and 1N34 just because if you need germanium its one of the only old school ones left in any sort of quantity. Also ltC1044/7660 charge booster. Used as a bias supply in jillions of LCD displays.

I searched for one but there is not even an inexpensive N-channel MOSFET which I find puzzling.  MOSFETs also tend to work poorly with logic level drive below 5 volts.

I might add SD103 as the schotkey small diode and 1N34 just because if you need germanium its one of the only old school ones left in any sort of quantity.

I like the germanium 1N270 myself but for a jelly bean small signal schottky diodes I would probably pick the BAT41 (low leakage and low capacitance) and BAT48 (high current).  They are all pretty expensive though compared to the 1N4148 and similar.

irf510: the most unique mosfet in my view.

regulators:
AM1117, different flavors
TL431: cheap.

logic:

HC164: my goto shift register

timer:
12F675: program anything to it
