Reading a part

[electrousa]

Hello there,

Who can tell me what the attached part is? One is marked with 701 006 another with K2a.

Thanks

Units on the left, transistors, although no idea if npn or pnp. Nothing on Google.

Item on right, no earthly idea. Google(if you put an LM in front) hit on everything from gloves, to diesel engine parts, but no ICs. Nice fingerprint, by the way.

You can work out what those SOT23 deivces are with a multimeter. SOT23 transistors often have a standard pinout, so with a diode tester multimeter, you can probe the pins to work out if its a NPN, PNP, or a dual diode. If they are mosfets, you might have to power them up first and check the voltage across the source-drain. Again, pinouts for all the above devices tend to be standard.

As for the 8-pin SOIC, if you have the board it was taken from, you could use that to get an idea of the pinout, at least the power supply pins, inputs, outputs... If its an opamp then that could narrow it down. Usually theres a manufacturers mark, whichi could be that white blob on the left, but I can't make it out

Thanks a lot for the helpful suggestions.

The 8pin IC is extremely likely to be a LM301;

The K2A might be one of the "K2" devices seen here;

(probably a BCW72)
