[SOLVED] Looking for a replacement for obsolete NPN transistor - Page 1

content: Hi all,Replaced a board in an airconditioner today, turns out it was getting damaged due to a faulty motor and as a result I killed the new board as well. As far as I can tell, the only part that is damaged is a NPN transistor, "2SC4487" (seized motor, high current burning out transistor). This seems to be an obsolete part and is not available on RS Components or Element 14.Just wondering if anyone can recommend a replacement? I'd try myself but it seems a little specialised (also in an odd package) so I assume it's not as simple as swapping in a bog standard NPN with the same current and voltage ratings. Datasheet I've found for it is here:https://au.mouser.com/datasheet/2/308/EN3093-D-310398.pdfCheers for any help!

The display is a 160x160 pixel monochrome LCD, part number PVG161603G, which is of course unobtainable, and the manufacturer of the test equipment is now defunct.I'm familiar with character LCD display modules, most of which are HD44780 compatible so are somewhat standard, but I have no experience with these graphic LCD modules. Are they also fairly standard or not really?This display uses four HD66206 drivers. I have searched for 160x160 displays using this driver but came up pretty much empty.Is there anything currently available that would be a compatible replacement, or am I pretty much out of luck?

The pinouts are similar, but not identical. Screen layouts as to pages (8x8) and columns are the same. Control codes are similar, but not identical. If the pinouts are the same, it may work, but there's a good change it won't. If the pinouts are different, there is probably no chance, even if you made an adapter pcb. Of course that advice is based of a set of 2 only.

timestamp: May 31, 2020, 09:18:42 pm
content: I'm going through an HP 334a distortion analyzer and discovered a p-channel JFET on the rejection amp board was replaced with a component of questionable compatibility after failing to adjust bias at A3TP2 within a certain range. The service manual for the analyzer specs Q4 as a TI SFB 2696 (1250μs, 4ma), and the component in its place is a Siliconix device numbered "5-006 7340". I wasn't able to find data on either part.Does anyone have any info on these JFETs? What might be a good substitute for the original part?I found a TI semiconductor catalog from 1966 and was't able to correlate any of the FETs listed with the part no. 2696. There was a 2N2696, a general purpose transistor, but Q4 is very much a JFET.Thanks for any helpedit: I did some more sleuthing and found the siliconix part is OEM.

content: Hi All,I have a project about LTE RRU equipment repair and diagnostics. Generally speaking I have to write FPGA diagnostics firmware for some LTE RRUs with AD9368 transceivers. Unfortunately, the lack of AD9368 documentation and source codes is the only impediment. The RRUs has two transceivers AD9368-1 and AD9368-2. Any documentation help or source codes will be appreciated and even paid. Or any information like "it is a rebranding of AD9375" also will be helpful. I have a feeling that AD9368 was a something like a prototype and later it has been rebranded/renamed to AD9375 because it has almost the same specs (from what I see in firmware) and even DPD (digital predistortion)Thanks in advance

content: No big chances for luck, but maybe. This oscilloscope has been produced during 1980s and 1990s in the USSR and later on Lithuania by a company called Rimeda (during USSR period companies didn't have names). English version of this manual does exist for sure, but I had no luck to get one. I have scans of a few first pages.P.S.Proper name in Latin alphabet would be S1-112A. If anyone needs it I've got Russian and German manuals for this unit.

I've seen capacitors leaking, but this looks like some kind voltage regulator.On the picture attached I am pointing to the substance around that area. Most of it was around MAX637 (switching regulator) and SMD10 . Capacitors near was clean and looked good.Anyone can help me to identify that SMD10 component ? Could it leak ?Thank you!

Everything was good for about 2-3 minutes.Later screen went black. but indicator panel is partially functional (e-g battery charging showing something, caps-lock, num-lock showing something ).At that point i took it apart and discovered that substance and it was kinda bubbling around these elements. I cleaned up the area and after power is on I don't see more of the substance coming out from any elements.Other thing I noticed that heatsink on the back of the laptop where power plugs-in is getting very hot.So at this point I ordered capacitors as a first step in attempt to repair it.Thanks.

content: Hi all,My HP E5100A network analyzer lost its calibration after a sudden power-off.On boot it now shows multiple errors “backup data lost” and “corrupt media.” The service manual points to corrupted calibration flash ICs U5-U8 on the A1 board.I have read 4 dumps from my unit, at first glance they seem okay-ish so I would like to compare them with dumps from a working unit - maybe then I can somehow fix my own dumps?So I’m looking for binary images of the four AM29F010 Flash devices (U5–U8) on A1 board. Each one is 128kB.If you have a functioning E5100A or already have dumps of these four chips, I’d really appreciate a copy.I’ve also attached my probably-corrupted dumps. Maybe someone can tell if they are really corrupted and, if so, whether it’s possible to fix them?Sadly, I don't have the equipment that HP lists in the service manual for recalibration.Please PM me or reply here - thanks a lot in advance!

content: Hello,I own this great SONY/CISCO APS-172 switching power supply.https://www.artisantg.com/TestMeasurement/81140-1/Sony-APS-172-AC-DC-Power-SupplyIt was build in Indonesia by SONY to feed the Catalyst 4500 series. It is specified 28 amps at 50V and I used it easily up to 30-32 A at 50V easily without any issues, voltage drop about 1V. It will output 113A at 12V !!!!! It also has some security mechanism built in, short circuits are detected. It is also possible to control the shut down/turn on of the power supply via the Catalyst 4500 rack interface connector.Unfortunately I miss the manual of that power supply as well as its schematic diagram. There is a rack connector on the back and I am curious to understand its different functions (ie, what the pins do), right now I only exploit two pins of this connector to control the activation/shut down of the power supply externally. Also I am trying to locate the voltage reference circuits in the power supply as my goal is to try to try increase output regulated voltage from 12 to 13.8V and from 50 to 52 or even 54V. I have little experience with switching power supplies and I have no clue where to look at inside, it is a highly complex and sophisticated device with lots of boards internal connectors etc.. I really need the manualThanksRegardsPeterI could not find ANY info on the net about it, so if you have an idea where I could find some more info, please inspire me.RegardsPeter
