Compatibility & sourcing notes
The FMD FT25C is a standard 25-series SPI EEPROM (20MHz, 1.8~5.5V, SOIC-8/TSSOP-8/DIP-8) with the standard WREN/WRITE/READ/RDSR/WRSR command set and AT25-compatible pinout, so it drops in for the same density. Confirm the density code and page-write size (e.g. 32-byte page) match the original and check WP/HOLD pin usage; do not replace a larger part with a smaller one.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
