Substitute Part Grouping Explanation

The 24AA1025-I/P qualifies as a parametric equivalent to the 24AA1026-I/P based on strict alignment of critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Memory capacity and organization remain identical at 1Mbit with 128K x 8 configuration, ensuring software compatibility and address space equivalence. The I2C serial interface operates at the same 400 kHz clock frequency with matching 900 ns access time and 5ms write cycle specifications. Supply voltage tolerance spans the identical 1.7V to 5.5V range, and operating temperature limits remain -40°C to 85°C. Both devices utilize the same 8-PDIP through-hole package with 0.300" (7.62mm) pitch, enabling direct mechanical substitution on printed circuit boards. Compliance certifications including RoHS3 status and MSL rating are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 24AA1026-I/P and 24AA1025-I/P maintain active product status from Microchip Technology, ensuring continued manufacturing support and availability. Selection between these parts is based on inventory availability and supply chain considerations rather than functional differentiation. The 24AA1025-I/P currently maintains higher inventory levels at 3240 pieces compared to 843 pieces for the 24AA1026-I/P, making it the preferred choice for applications requiring immediate procurement or high-volume deployment. Both devices carry identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and consumer applications. MSL rating of 1 (Unlimited) for both parts eliminates moisture sensitivity constraints during storage and handling.
