Where did you order it, did you check and order by the part number SY8388ARHC

Measure the sizes with a micrometer.

Google works to find the attached datasheet.

Post the link where you bought the chip, the provided info was correct, seller sent the wrong part or you ordered incorrectly.

Yes i ordered with the same part number mentioned by seller, mentioned the link above

The vendor shipped the wrong part. Very confused about the shipped part size which may be a fake. There is a 1 star review on this same part on their website noting the same issue. Perhaps your review? Reach out to the vendor for a refund.

Suggest to source the proper and same part number from LCSC. We use them often for parts sourcing and also met them at an electronics fair in Shenzhen. Never had any issues with the quality of their parts.

Yes same happened with me, the review is not mine and I have already requested for a refund but I need to be sure that the part is exactly same, I mean these two ics have same markings

From the public documents, if the component has the B3*** SMD code, the part body size must be 2.5*2.5mm; QFN-16. To me, anything else is a fake. The larger packaged version of this part is with a different SMD code. Source it from LCSC. If the vendor truly believes the parts are the same, request a datasheet to support the claim.
