Hello,

When I was repairing a motherboard, I realised that this part was getting quite hot and I decided to replace it. However, I couldn't find the part on the internet. There is nothing but ‘B844 idx’. How can I find this part or its equivalent.

 

Best bet is to ask the manufacturer of the product. If anybody on the planet knows it will be them. Of course, it is possible they will totally ignore you since they would rather have you buy a new unit rather than repair one. Even if you know what the part is there literally no guarantee that you can buy one. You might have to buy a whole reel, usually 3,000 pieces. It seems unlikely you would want to do that,

Oh, thanks a lot. The manufacturer sent me a quote form suggesting me to buy new. But I can definitely research and find it in my country
