RT6310BGQUF

[Olimpiu Puscas]

Hi everyone, I can't find anywhere this chip to buy RT6310BGQUF step-down converter with 3.3v/5v LDO for a Lenovo ThinkPad E14 Gen4 laptop,not even in China. Anyone knows an alternative chip that I can use? Thanks

thank you mon2 but none of those are equivalent, I must contact Richtek...

This store is selling assorted chips. The one you require is the most right in the listing. The other devices are from ASM (Asmedia, Taiwan) and are PCI Express switches or PCI Express bridges. The parts are not intended to be equivalents. Just ping this vendor (if you wish) to confirm that they indeed offer this Richtek part. Better choice is to ask the factory but the factory may not reply for a single piece request. Most of China is about how many containers of parts do you wish to buy for their early retirement.

I've sent an email to the sales department in Beijing and will ping that vendor also. Thank you for your help.

Hi,

Did you ever find out where or how to purchase this chip? I have a Lenovo E15 Gen 4 with the exact same chip blown out.

Thank you.

Yeah, I'm out of solutions too. I inquired on LCSC.COM a couple of weeks ago and they replied saying that they're out of stock and that they don't know when they're going to be back in stock.

Meanwhile I'm going to try to get a motherboard for parts and roll the dice to not get another one with the same problem.

If I find out about anything else I will let you know.

Thanks for the reply, good luck.

Just received a reply from one vendor on Aliexpress and they claim that there is no stock of this part in China. Waiting on a few others to reply. Best feedback will be from Richtek factory.
