820-3787-A shutting down

[CRC2018]

Received a Late 2013 Retina Macbook Pro 15 inch today. It's randomly shutting down which I have replicated. I've read around and i'm seeing U7310 listed as a common failure point on these boards. The only issue i've got then (assuming correct diagnosis) is that I cannot find the recommended replacement of FDMF6708N in stock anywhere at any reputable suppliers. I can get FDM6823A and FDM6820A from a reputable supplier but am unsure if these are compatible replacements as there seems to be some minor differences. - Pin 1 of FDM6708N is ZCD_EN but on FDM6823A and FDM6820A Pin 1 is SMOD.

Any thoughts on possible replacments or sources of FDMF6708N?

FDMF3030 could be a suitable replacement but I don't think anyone tried it yet.

Certainly looks like it from the datasheet - I shall order a few and try them!

Just to report back on this for future reference - FDMF3030 works fine as replacement for the original FDMF6708N recommendation.

Got mine from mouser!

Thanks for feedback.
This will help other members, as FDMF6708N seems to be out of stock.

BTW, original Apple chip, is FDMF6808N...

CRC2018, did this solve your issue with your Board?

Hi Thomas

yes just replaced U7310 with FDMF3030 fixed the issue - i've cinebenched it several times since replacement and no more shut down.
