Substitute Part Grouping Explanation

Substitution eligibility for the 24LC08BH-E/P is determined by strict equivalence across the following critical parameters: memory capacity (8Kbit), memory organization (256 x 8 x 4), serial interface protocol (I2C), clock frequency (400 kHz), access time (900 ns), write cycle time (5 ms), supply voltage range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and physical package configuration (8-DIP through-hole). The substitute part 24LC08B-E/P meets all these requirements without deviation, establishing it as a parametric equivalent. Both parts are manufactured by Microchip Technology, share identical electrical specifications, and are housed in the same 8-PDIP package footprint, ensuring direct functional and mechanical interchangeability in circuit designs.
