I have a Fujitsu server (PRIMERGY RX300 S8) with a failed I2C EEPROM on the front panel PCB. I would like to order the correct replacement components, but I am unable to identify the exact series/capacity of the chips.


I believe the top EEPROM (D3) is an STMicroelectronics 64Kbit EEPROM, probably from the M24C64 series.

The bottom EEPROM (D2) is completely unknown to me, I can't seem to find anything from a search engine for "I2C EEPROM H250 2GB"

I am certain that D2 and D3 pictured are I2C EEPROMs in a TSSOP8 package, I just don't know the model numbers and I'm hoping someone here can identify them.

I am aware that I could purchase a complete front panel PCB from the vendor or eBay, but that is not my question.

    \$\begingroup\$ You sure its not a RAM chip? Quick search I found this psaparts.co.uk/memory-laptop/fujitsu-siemens/… \$\endgroup\$

    \$\begingroup\$ @dka13 that's obiously not an IC \$\endgroup\$

  • \$\begingroup\$ @KevinWhite The question is regarding chip identification, not troubleshooting. I would like to know the exact model so I can purchase replacements. \$\endgroup\$

  • \$\begingroup\$ @dka13, your link points to an SoDIMM RAM module, a completely different component from the one in the image and also not in any way compatible with a Primergy RX300 Server. \$\endgroup\$

1 Answer 1


Quite possibly a 2.5V serial EEPROM similar to AT24C1024B, made in the 50th week of 2012
