What about 66=5F, 65=5G and 5E=5E?

@madan1, post zoomed up clear pics of each component for a review of the package(s).

Where is each component being used ? Brand name? Post as much detail as possible.

Asus e402ma laptop, all similar package as the above one, all part of the power supply ( look like switching ICs ). Let me know if you need better photos.

66=5f - could this be possibly 6S=5f ? Pour some alcohol over the markings and try to review under bright light at an angle to confirm.

6S=xx is Richtek RT6576DGQW. Datasheet is attached. Confirm if a valid match with the # of pins on your original device.

5E=xx is Richtek RT8248AGQW. Datasheet is attached. Confirm if a valid match with the # of pins on your original device.

The motherboard shown in the pictures is an E406MA

Sir, you are totally correct. I hope I haven't wasted people's time by this typo..

Thank you for the reply! Really appreciate it.
Just made some hi-res photos.. oh well, looks like the camera has better eyesight than me.. used to be the opposite

Probably the IC I'm most interested is the 65=5F, this one should be changed for sure. In other model ( for which I was able to find boardview ) asus is using ATK1602GQW in it's place.. if this helps.

Re: Asus E406MA ic 2N=4H replacement

Any ideas?

Re: Asus E406MA Richtek 66=5F, 65=5G and 5E=5E

Ok. Updates...

1) 65=YM is a private part for the logic board customer.

Richtek will not share anymore details but was the reply from their office.

2) after more searching, found a stocking agent in Shenzhen.

10pcs =60 usd
Shenzhen Hong Ming Electronics

They have stock.

Ask them for other Richtek parts as well. Be sure to update this thread with your progress. This is a very solid supplier whom we have used for past repairs.

Thanks, I sent them a message, but if they are not willing to sell smaller amounts, then the board goes to the scrap bin.
A working board for this laptop can be obtained from aliexpress for roughly the same price.

If the ATK1602GQW is pin to pin compatible those are much cheaper .

Re: Asus E406MA Richtek 66=5F, 65=5G and 5E=5E

The seller is the only one that has access to this component. They did ask if the buy is for 5pcs / 10pcs ? So I suspect that they will be ok with 5pcs. Otherwise it is more ewaste for this logic board.

Re: Asus E406MA Richtek 66=5F, 65=5G and 5E=5E

Yes, the seller offered 5pcs, but I went with buying another physically damaged e406ma board for 12GBP/17USD. I guess, if I was willing to wait more, I could have scored even a cheaper one.
