And here is the older version. Same question and one additional one: I guess HRS does not stand for "hotel reservation service" in this case. I wondered, if it could mean the connector was fabricated by hirose, since these are the consonants in the name it is also a Japanese company.

Yes, that is Hirose's logo.
The first plug may be by Binder, I will look in some catalogs.

What might this be?

Relay in a vacuum so that there is no arc when it breaks or makes. Minimises noise when switching an amp on or off for example. Could be timed, could simply be instantaneous. The vacuum is the key feature.

Hi there,

It would be nice if someone can give a suggestion for that plug on the right.

I'm going to redesign that PCB on the left so I do not need an exact match for that plug. The function is a trigger button assembly for a TIG welder. I did get lost on Digikey's website find a suitable product.  It has to be some kind of card edge design. Because I have to fit it in a torch handle so it must not be too far above or below the level of the PCB. That PCB is 1.6mm in thickness. That plug has a height of 5.5mm and a width of 11.5mm and a length of 9mm. A two position version would be ideal. And of course it is just for very low currents.

Thanks so much for your time.
goto considered awesome!

This seems to go into a similar direction. Maybe some key words are helpful for your search.

The capacitor with the red markings. It has unusually large terminals, that I've never seen before. I expect some capacitor, probably NP0, which has stable frequency response up to 2 GHz, since it's an AC coupling part in a 2 GHz probe.
Anyone has an idea who is the supplier and the series? Is it an Agilent custom part?

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Parts can be made available for vertical customers much earlier than to the general market, with the common secrecy/NDA involved. Besides, that is just AVX, but I wonder if other manufacturers might have released this type of component earlier.

I'm having a little trouble identifying some SOP8 MOSFET's, I'm after the datasheets.

W204 dual N channel with typical pinout.
5139 single P channel with typical pinout.
Siliconix 3005 dual N+P.

Several brokers are offering SI30058DY-T1-E3, but I can't find a datasheet.

I can't find any clues at all. It's almost the hardest thing I've ever seen!

I know, I have specific BOM lines in products, that are made for my company.
I was just wondering if this was an off the shelf part.

Thanks for trying... So what was the hardest ever?

I can't remember for the Siliconix part but if I remember correctly the other two are pulled from equipment of the same era if not both from the same device which could have been some random old Sony design or an old hard disk including IBM / Maxtor / Sony./ Quantum.

I like identifying chips as a brain exercise, and I can solve them most of the time, but this one really knocked me out.  :palm:

I thought those markings were familiar. This is an excerpt from my HDD/SSD IC database:

Quote
P-channel MOSFET, Sanyo, marking 5139, SO8 package, same pinout and specs (?) as PHK04P02T, dates from 2003

Edit:

FW204, Sanyo, 2 N-channel MOSFETs, 20V, 2A, marking W204, SOP8:

Edit #2:

Hahaha

It's an FSS139.

FSS139, Sanyo, P-Channel Silicon MOSFET, -20V, -4A, marking S139, SOP8:
