The Microchip 24LC08BH-I/SN is an 8 Kbit serial EEPROM with an I2C interface, organized as 256 x 8 x 4 bytes.
The 5 ms write cycle time per word or page is consistent across the temperature range, so no derating needed for cold starts or hot enclosures.
Within the same Microchip 24LCxx family, the 24LC025T-I/ST is a 2 Kbit variant in a different package (TSSOP-8, tape & reel), and the 24LC01BHT-I/MNY is a 1 Kbit part in a 2x3 mm DFN. Neither is a direct pin-compatible swap — the 24LC08BH-I/SN is the 8 Kbit, 8-SOIC version you want for that footprint. For a higher-speed option, the 24FC04-E/MS runs at 1 MHz but needs a 1.7V minimum supply and comes in an 8-MSOP.
Yes — the supply range goes up to 5.5V, so running it at 5V is within spec. The I2C bus thresholds are VCC-based, so a 5V master talking to this part at 5V supply works without translation. If the master is 3.3V, the 2.5V minimum supply lets you run the EEPROM at 3.3V as well.
