We were using the FM24C04-S (soic8) on some older boards and now that part is obsolete, so my question is…Can we use the FM24C04B-G part (soic8) as a replacement?

Hi,

Yes, you can replace FM24C04-S with FM24C04B-G. Both have the same pinout. FM24C04B-G has more read/write cycles (100 trillion instead of 10 billion in FM24C04-S), a higher maximum bus frequency(up to 1 MHz), and lesser leakage current.

Thanks,
Ritwick
