Photo shows cm reference.
I do not have original circuit anymore, but I recall that part was located very close to main heater power bus. Device was not soldered, just press fitted by contact spring action. Heater had a dedicated thermocouplethermistor and thermostat very close to heat source, this device was separated by strong plastic wall from a heater. Thus I would think it is a NO thermal (suicide) switch rather than a sensor.

It's an obsolete "voltage dependent resistor" AKA Varistor from Stackpole. Stackpole SV230K23.

Here are the specs:

Part of the recently acquired NOS (New Old Stock) parts I gained a few crystal oscillators, good to have around! There is one in particular that I am interested in finding the datasheet for but can't seem to locate one. It's a Corning MC937X5-002W 155.520000 MHz oscillator which I am very interested getting some info on. I have attached some pics. Any help would again be greatly appreciated.

Here you go.

It could be varistor. I would like to test your suggestion >:D, but I do not have HV source at the moment.

I am looking for a datasheet of C0-J05 voltage regulator. Vin ~5v, Vout should be in 2.8-3.6V range. SOT-23 package with 5 pins, 2005-2006 vintage.

The closest match I found is Ricoh R1154N105B, but it has way too high output voltage and markings are not identical.

Hi electr_peter,

It is most likely RT9701

Hello all, hopefully someone can help me identify this particular component. Unfortunately, it failed and whats left does not have any markings on it, and the only other example on the board looks like its about to suffer the same fate, but hopefully its still recognizable to someone.  See attached, R15 is the failed component, R56 looks like its the same part, except it appears to be swelling. Thanks in advance!

Hi electr_peter,

I think you-re right about that. The data sheet you link to doesn't include marking codes, but I found an older data sheet from year 2000 with the marking code C0 in it: http://wenku.baidu.com/view/77ad2c00bed5b9f3f90f1cb2.html
So it's the R9701xB version with the chip enable pin included. The pinout matches too.

The 3 letters/digits after C0- are probably date codes.

If you google RT9701 you'll find several pictures of SMDs with the C0-xxx marking on it.

Is the part used for an USB port?

Thanks for suggestions, Jad.z and AndersAnd. You are probably right about the part.

Device does not have USB port. There were 2 devices with the same marking, both in a power supply line. It provided ~3.3V to 2.0V regulator (with massive filtering) for a DVD media device (MT1389 - DVD player SoC).

I thought could be voltage regulator as that SoC require few exact voltages, but I am not sure.

I got some junk that used to be laser range finder from around 1985. I am looking at flash bulb trigger circuit and I found a component which is made by RCA (?) - S2600M. Funny thing I even found a datasheet for this thing, but still I am puzzled - what it is? BJT? Seems not, what would be correct symbol for it?

It's an SCR - take a look at w2aew's video if you are confused -

Yep, also states it's a thyristor....how many more clues do you need?    :-//

Yes, thanks. Sorry I must have turned off my brains at some moment :) Definitely missed the word "thyristor" in description.

New Ti 84 - Based on the EZ80, big upgrade from the Z80.
Anyhow, between the French version that sports a full exact calculus motor (everything that can written as a fraction, root, power or trig is written as such)  and the "back to basics US version", there are minor component differences.
All are easy to identify, except the D01 in the top left... Not sure about it:

Any ideas?

Footprint looks very strange for a diode.  :-//

You could take a punt and just use a signal diode.
Probably better to reverse engineer that part of the circuit including the IC, then ask for advice, maybe in a dedicated thread.

Looks like an IR data port, so I googled TI-84 Infrared and sure enough some later models come with it.
Could it be that instead of what you thought it was?

Does not seem to fit the bill... THe IR is not a difference between these two models...
Ti sometimes uses custom packages in its calculators to make modding them much harder.

Edit:
It's a two colour led. The little circuit below is a classic two led driver...

That's why I thought it was some IR communication setup, because it did look like two LEDs, but you are right, they seem to be both for output not one for input and the other for output.

Hi All. I am look for the name of this type of connector and where I can order it. Anyone know who makes it and what it is called?

Thanks for the help.

How about this? Stator to R&R Connector and Terminals (about 2/3 down the page, on the right)
aka Yazaki 3 Pin Connector

Context is always helpful.  It looks somewhat like the kind of connector you find for traditional incandescent sealed-beam headlights on a vehicle.
They are basically the kind of connectors that attach to spade-lugs, but held within the white plastic shell.

Sorry, I should have explained better. The connector is used in an electric scooter. I had it but some bastard stole the old batteries with the connector still attached. I have new batteries now but I want to get proper replacement it, and I guess I will also need the contacts too.

tsmith35 thanks for the link,  The R&R kit may be the ticket.
