Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC02BHT-E/LT is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (2Kbit, 256 x 8 configuration)
• Serial communication protocol (I2C interface at 400 kHz)
• Electrical performance metrics (900 ns access time, 5ms write cycle time)
• Supply voltage compatibility (2.5V ~ 5.5V operating range)
• Temperature rating coverage (-40°C ~ 125°C)
• Physical package specification (SC-70-5)
• Regulatory compliance status (ROHS3, REACH Unaffected)

The 24LC02BT-E/LT meets all substitution criteria as a parametric equivalent, differing only in internal die configuration while maintaining identical external electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations
