24LC08BH-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC08BH-E/SN is an 8Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial communication. This component operates at 400 kHz clock frequency with 900 ns access time, supporting supply voltages from 2.5V to 5.5V across an extended industrial temperature range of -40°C to 125°C. The device is housed in an 8-SOIC surface mount package and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Finding equivalent or substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or optimizing procurement across multiple suppliers while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC08BH-E/SN is determined by strict equivalence across the following critical parameters: memory capacity (8Kbit), memory organization (256 x 8 x 4), communication 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), package configuration (8-SOIC), and mounting technology (Surface Mount). The identified substitute part 24LC08B-E/SN meets all these requirements, differing only in manufacturing lot designation and moisture sensitivity level classification, which do not affect functional or electrical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 24LC08BH-E/SN and 24LC08B-E/SN are active products from Microchip Technology with full ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications. The substitute part 24LC08B-E/SN carries verified programmability certification and maintains significantly higher inventory availability (4268 units versus 991 units), supporting supply chain resilience. Selection between these parts should be based on immediate availability requirements and inventory management objectives, as both components deliver identical electrical performance and mechanical compatibility within the specified application parameters.
