Hello, I'm repairing an old mini-PC Gigabyte Brix. I found a photocoupler wich seems dead. On the top of this SMD 6 pins component, there is wrote : 4N3R. I found 4N3 serie datasheet but I can't found what's mean « R » for find similar. Could you help me pls ?

Re: Where to buy photocoupler 4N3R or similar please ?
Are you sure it is an "R" and not another letter or number? Can you post a clear picture of the component?
It could be a PJ4N3KDWLast edited by R_J; 05-04-2021, 06:37 PM. -

Here two pictures of two components on the board. It's « R » but maybe should be read verticaly RN ? I found a lot of same chip 4N3 but nothing with R.Attached FilesComment

i doubt thats an optocoupler, there is not enough seperation between the pinsComment

It is a PJ4N3KDW The "RN" is a date/mfg code It will be different between parts, (ie:47).

Ha yes, you are right, it‘s this mosfet. I dont understood first what a photocoupler did on the board of this mini pc with Celeron and with a very small external 40W charger ? But I found AN4 photocoupler datasheet and pin 6 was unused and matched with the open line measured. Wrong way.
PJ4N3KDW is hard to find, I tryied to find equivalent onr. And I found 2N7002DW

with same pins, same internal schematic and could you help for these specs pls, it's equivalent ?

This is a new item at Electronic GoldMine that has arrived within the last few weeks
Here is the link for them I know for sure that it works because ( I tried it on mine soldering station ) I bought two of them and I just bought two more of them so I have some extra replacement ones in my parts bin

Hello everyone, I'm troubleshooting our malfunctioning Bosch serie 6 washing machine and can't find many answers online (or ones that I can make sense of). At first it started showing error E:60 -9 and would not start a program. After several restarts it's no longer showing the error codes, but when I start any program (drum cleaning for example) it fills the water in but the drum doesn't start spinning. I couldn't find any physical obstruction, but turning the drum by hand I feel resistance. I tried opening it up, trying to inspect the motor brushes. This model either has a different motor that... -

I want to replace samhwa RG 250v 1uf capacitor which has no ESR value and has capacitance less than 280pf.
It is possible to purchase WCAP-ATG5 in local electronic shop.
But I want to know that whether WCAP-ATG5 capacitor has similar or better quality than smahwa capacitor or not.
Is there anyone who has experience to replace any bulge or faulty cap with cap from Wurth Elektronik?

I want to replace the caps of my Sega Dreamcast power supply. But one of them is a 400v 47 CE Z. Some how I cant find that serie or the replacement for that serie.
I am not sure if they really are Panasonic. They are all CE with FC and NHG and that are Panasonic models. But all caps are branded with M.
Anyone can tell me what serie or replacement serie this is?
