hi, it is normally like this: Attachment: 6645-PCBF-ChipOrder.jpg [ 171.54 KiB | Viewed 11425 times ] But of course could be different for a number of factors such as design is modified from a 2 flash version, or firmware dev didn't care. |

Is that one of those DIY ssd boards? |

Thanks I will try to transplant the memories to another functional SSD

Use 100% same PCB. Not other one. |

If not, then you're just torturing the drive. Most of the components are damaged, I transferred the controller to another SSD, it gets too hot

This looks like the result of an overvoltage on the 5V supply. This typically happens when the user swaps dissimilar SATA cables between different PSUs. If this is the case, then the capacitors are unlikely to fail. I would remove all the DC-DC converter ICs and then test for shorts between each inductor and ground. If there is a short, then one or more of the major ICs will have failed. There would be no point in transplanting a dead NAND. If there is no short, I would replace the DC-DC converters. |

Nands are usually armored, but of course better check before all the work. |

I saw a similar disaster at Tom's Hardware. The SDRAM was shorted, but the NANDs survived. The user replaced all 3 DC-DC converters and the SDRAM. He also replaced the controller, but I don't think that was necessary (he did this before he posted). |

How I can replace this components? or find a compatible one When removing the controller, the capacitors that were around it are no longer short-circuited (I measure using the red tip of the tester on ground and the other tip I test that the capacitors do not give 0 on both sides) Around this integrated component in the image the capacitors are shorted

I've just started to have a look at your converter ICs. I haven't been able to identify the "CDEA" IC, but the following photos of similar boards have "CX7HA" and "CXAKA" in its place. https://i2.kknews.cc/-DVtTWEStxIrTfeFWWUrA_-bn82da_5ovjJjHk4/0.jpg https://img2.quasarzone.com/editor/2023/02/22/aec9fe47c455f0e23b428c98a0d8dd4e.jpg SY8035DBC, Silergy, High Efficiency, 2.7 - 5.5Vin, 5A, 1MHz Synchronous Step Down Regulator, marking CXxyz, DFN3×3-10: https://web.archive.org/web/20190913190402/www.szyucan.com/upfile/IC-PDF/SY8035.pdf These are two compatible ICs: https://www.sun-flytech.com/images/pdf/2020060353c84.pdf (MT3033) https://hmsemi.com/downfile/HM3450D.PDF (HM3450D) |

S2xyz can be either an SOT23-5 or SOT23-6 IC (pin #5 of the 6-pin package is not used). It appears to be either an APS2420ATBER (5-pin) or RS3402 (6-pin). Suitable substitutes appear to be SY8009AAAC, SY8009BABC, JW5222SOTB, JW5222SOTA.
