Thanks for the message, Are FDMF6708N, FDMF6808N, and FDMF3030 the same ??

Fdmf3030 is available, but it has a minimum order quantity requirement of 3000 qty..... I'm stuck😣😣😣😣

I am looking for a solution, Should I conclude that it can not be repaired until I buy it from Farnel or Mouser (With 1year delivery time ?)

Other than Aliexpress, I could only find this option https://www.ebay.com/itm/231802143156 https://www.ebay.com/str/laptopmbseller

SAD, It has 9 months to 1 year lead time in mouser and farnel, I may find some old board to remove this component. How are these buck converters are going bad? Is it only in the 2013 board? Will it be ok if I remove the component from an old 2012 board?

If that's not fine can I order this one? Could you please confirm...

Will it be ok if I take FDMF6808N from an old board?
