What's this please? (Component Advice)

[gamalot]

All the flip chip IR LEDs I've seen also have a body that goes through the PCB, but both pins are on the back side, this one is really special!

Hi
I hope you all will be doing great.
can anybody identify this component plz. it is an SOT23-6, 6 pin device used in microscope LED Light. it is the main chip on this controlling pcb so my guess is led current controller ic, but can not find any datasheet for this. the pcb is marked with 1s6067a.
Note# if u zoom in on the pic u can see the marking as well as the whole pcb...
thanks

my guess is led current controller ic

I don't know what it is either, but my guess is a boost converter to bump up the 5V to something a string of LEDs can use. Of course, that can current limit as well, but I don't think that's the primary function (of the chip).

[PA0PBZ]

I agree, boost converter, you can see the coil and the diode on the pcb. Probably something like an SX1308.

RY3715

Blimey. Well spotted!

[fkfaraz]

Thanks @PlainName @gamalot @PA0PBZ

You have saved me. The RY3715 seems to be right due to the input voltage of 5.5v (which is USB Voltage). All other Spec seem to be equivalent to each other. so i will order the ry3715 and will see.

I found these ICs among an old hobbyist's stock which was donated to our hackspace, and can't find any data about them. They appear to be early (1978) Texas Instruments surface mount chips, clipped into plastic carriers. Part number is SN6331.

Can anyone enlighten me, please?

Hi there,

I hope someone can help me out. The connector shown is from a 1997 Toyota Starlet, it makes connections to the fuel pump and the level sender unit. My objective is to purchase the tab contacts; I can reuse this rectangular connector.

How about that company logo shown top-left? A 45 deg rotated hash sign. On one of its sides of this connector there is the number 10796.

Any information about the manufacturer and product series?

Thanks!

[HwAoRrDk]

That is the logo of Sumitomo Wiring Systems.

What is the pin pitch of the connector? How wide are the contacts? Is it sealed or unsealed? That is, where the wires enter the connector body, are there rubber seals?

I don't think that number is the part number, as their part numbers are of the format XXXX-YYYY.

From the shape, it looks like it may be Sumitomo TS series, although that white latching flap thing on the back is not a feature of anything I can see in a 2009 catalogue. Maybe if you try looking for a copy of an older product catalogue from the '90s you may find it.

Edit: I found this document: https://www.toyota-tech.eu/wire_harness_rm/RM06H0E.pdf. It seems that number is a Toyota part number. That particular connector is listed there. They list it as having type "2.3 II" terminals. You should be able to buy these terminals from various places. They might also be the same as Yazaki "090II" terminals.

[Zeyneb]

Oh wow, Thanks for sharing. The pitch is about 4mm the tab width is about 2.2mm. the other row is at a 5mm distance.

Let's check that document right now.

Probably variant of SN5331 (Triple 3-Imput Nand/Nor gate, series Modified DTL) The Flatpack style hints at space- or missile grade. OTOH, some computing applications used those packages too. I can't find actual info on SN63xxdevices, but SN53xx was Mil temperature range modified DTL, while SN73xx was commerial modified DTL.

EDIT: the Modified DTL series seems to predate the DIL package. Even the commercial grade was packaged like this. So it could be industrial temp. range.

Thanks, Neomys. With those pointers I was able to find a little more information including an overview datasheet for the SN53/SN73 series.  Sadly it doesn't give pinouts or even truth tables, so I can't check to see if the SN6331 is indeed a NAND/NOR chip or what that means, exactly.

Although the Wikipedia entry for the Flatpack format only mentions the military standard MIL-STD-1835C, the datasheet I found references JEDEC standards TO-84 and TO-89. TO-84 is the 14-pin outline which matches this chip.

If anyone has a source for the pinout of this chip or the possibly matching SN5331 or SN7331, I would be grateful.

[rolycat]

Thanks again to both Neomys Sapiens and PA0PBZ.

Just to confirm the hypothesis, I wired up one of the SN6331 chips using a 3.5 V supply and did a quick logic test. It is indeed a triple 3-input NAND gate, consuming a fairly modest 11.3 mA with floating inputs.

Mystery solved.

I'm looking for the reference of a Germanium diode with transparent glass DO7 package and single black cathode ring.
Marking is "04" or "O4" in black.
Thanks...

Could part of the marking have been lost, and it's "OA"-something?

I have 4 of them and it doesn't look so on any.

Hello,
does anybody know this type of through-hole (IR) LED-package?

What equipment is that from? Year? Country?

[firewalker]

Does anyone know what kind of flow (?) sensor is this? It was extracted from a medical device. Two of them. I destroyed one.

A quick internet search didn;t produce any findings.

Being more specific than "medical device" could have helped. But here ya go:

The four digit number is likely a year+week date code.

Sorry for the late reply. These are in encoders from motorized linear stages from about the first half of the 1990s. The brand is Newport, but i have some indications, that they might be developed by Kensington-labs. I would locate both companies in the US, although later newport-stages in my possession are labeled to be made in France.

[Majorstrain]

I'm coming up blank in my search for the identity of this component.
 

The designation on the board is for a diode. It seams to be a transient suppression device of some sort.
It's around a stepper motor drive section of the board.

Does anyone have any ideas?

Cheers,
Phil

IIRC that's the Diodes Inc logo, so that should narrow down your search.

Thanks, That's a great lead.
