Part identification Single Inline Something
« on: February 26, 2020, 08:11:48 pm »
Hey guys

Part identification Problem for you:
I have a part in a beige single inline package that i can not identify.
It does not look like a resistor network though (measuring the resistance between connections is not conclusive more on that later).
Also the manufacturers site doesnt really reveal anything of use apart from that the company (Beyschlag) now seems to be a part of Vishay.
These are the searches I tried:

https://www.vishay.com/search?query=OZ6802&searchChoice=part
https://www.vishay.com/search?query=0Z6802&searchChoice=part
https://www.vishay.com/search?query=OZ68O2&searchChoice=part
https://www.vishay.com/search?query=138537&searchChoice=part
https://www.vishay.com/search?query=OZ68O2+138537&searchChoice=part


also google seems not to know anything about that part.
finally i looked through vishay's resistor, capacitor and RC networks that come in the right form factor and also that is not
reveiling anything useful.
I got that particular by dumpster diving so I wouldnt feel terribly bad tossing that thing out, it just is a question to me "what is that and what is it for?"

The measurements that I said are unconclusive are conducted as follows:
Mystery component in a breadboard with wires connected to every single pin the following order
lightblue white orange gray violett brown yellow green darkblue red black (this side has a dot presumably pin 1)
then all the following pairs of wires into an mTester one after the other (mostly because a multimeter without croc clips or even changable leads can make your life quite difficult if you have to handle a lot of measurements as they were done here)

lightblue - white resistor 684,5k
lightblue - orange resistor 99.81k
lightblue - gray ?
lightblue - violett ?
lightblue - brown ?
lightblue - yellow ?
lightblue - darkblue ?
lightblue - red ?
lightblue - black ?
white - orange resistor 785.8K
white - gray ?
white - violett ?
white - brown ?
white - yellow ?
white - darkblue ?
white - green ?
white - red ?
white - black ?
orange gray ?
orange violett ?
orange brown ?
orange yellow ?
orange green ?
orange darkblue ?
orange red ?
orange black ?
gray violett resistor 9238R
gray brown ?
gray yellow ?
gray darkblue ?
gray red ?
gray black ?
violett brown ?
violett yellow ?
violett darkblue?
violett green ?
violett red ?
violett black ?
brown yellow Resistor 2503R
brown darkblue ?
brown green ?
brown red ?
brown black ?
yellow green ?
yellow darkblue ?
yellow red ?
yellow black ?
green darkblue resistor 200k
green red 200k
green black resistor 99.95k
darkblue red resistor 200k
darkblue black resistor 99.60k
red black resistor 99.95k

the markings read:
Beyschlag
OZ6802
138537 (almost certainly a form of day code)

To make matters a bit more representative i have drawn a "schematic" in LTSpice (attachement) that shows the measurements results. Just be aware that the resistors in the schematic are obviously not actual resistors and rather measured resistance values used to represent the measured values so that there may be a pattern recognizable to those that know a bit more than me.

It is a custom resistor network made for a specific application.

Your measurements are not perfect, you need to account for tolerances.
785.8K is actually 684.5k + 99.81k, so lightblue is common (middle point) for white and orange.
200k is 99.95k+99.95k, so black is common for red, green and darkblue.
