How are you my brothers of the internet. I am working on a KTag rework project. The following is my purchase list

Infineon, BCR112 NPN Digital Transistor - 8 Pcs
ON Semiconductor NUP2105LT1G - 7 Pcs
NXP BC817,215 NPN Bipolar Transistor - 8 Pcs
MMUN2113LT1G - 3 Pcs
BC807-25-7-F PNP Bipolar Transistor - 2 Pcs
NFE61PT472C1H9L - 6 Pcs

I want to buy original European components. Anyone know where i can get them. If you sell or if you can buy them for me in Europe please PM me. From where i am from these cannot be found.

Thanks man. Seems rs-online has it all. Its better to be pointed somewhere by a peer here. Asking google can likely lead you wrong places

I just ordered all of these components from RS and when they arrived they're all made in China. Tried rework anyway but still doesn't work.

The fact that they are made in China does not mean that it is not an excellent product, what do you mean that it does not work?

I mean I have replaced all of the components that are required in the rework and I still can't read EDC17C60. I have bought an EU version and it works perfectly with GPT cable. I have just found another rework solution that says to change NFE61PT472C1H9L. This wasn't mentioned in my first rework so I'm going to replace these and see what happens. I have 100% confidence in my soldering ability so I don't think it's bad soldering.

I’ve bought new components from a different supplier. I’ll try again when I’ve got time and post result. It’s become a project now!!

The problem is not with the GPT cable. I have used it on another KTag and it works fine. I bought another KTag EU version which states that no Chinese components are used and it works perfectly. The problem is with the KTag not my soldering or cables. When I get time to rework it again with EU components I will post results. The rework instructions I found online clearly state not to use Chinese components and obviously the EU one I bought states that no Chinese components are used.

I have a ktag clone(China) reworked, read good with gpt cable, maybe your clone is bad, check the sd card too...

i wasnt saying its the cable, and i dont think changing the components you bought from a good supplier even tho they are made in china (like most are) is going to make a difference.
i asked you to post a pic of the filter area because on some pcb's there is an error there
also you will find most eu clones are just china reworked units
