Substitute Part Grouping Explanation

Substitute parts for the 24AA025-I/P are classified based on strict adherence to the following substitution criteria:

Parametric Equivalents maintain identical electrical and mechanical specifications: 2Kbit memory capacity, I2C interface at 400 kHz, 900 ns access time, 5 ms write cycle time, 1.7V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 8-DIP through-hole package. Parts meeting these criteria are directly interchangeable at the circuit level.

Manufacturer Recommended Substitute (AT24HC02C-PUM) operates at an elevated clock frequency of 1 MHz with improved access time of 550 ns, while maintaining the same 2Kbit capacity, I2C interface, supply voltage range, operating temperature, and 8-DIP package. This part provides enhanced performance characteristics within the same form factor and pinout.

All substitute parts are manufactured by Microchip Technology, maintain ROHS3 compliance, and are classified as active products with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 34AA02-I/P) are suitable for one-to-one replacement in applications requiring 2Kbit I2C EEPROM functionality at 400 kHz operation. These parts maintain identical electrical performance and package specifications. All are active products with ROHS3 compliance and confirmed inventory availability.

Performance-Enhanced Substitute (AT24HC02C-PUM) is applicable in designs where improved access time (550 ns versus 900 ns) and higher clock frequency operation (1 MHz versus 400 kHz) provide system-level benefits. This part maintains backward compatibility with the same supply voltage range, operating temperature, and 8-DIP package footprint. Selection of this part requires confirmation that the application circuit supports 1 MHz I2C operation.

Memory Organization Variants (24AA025UID-I/P, 24AA02UID-I/P) feature dual-die architecture (128 x 8 x 2 organization) while maintaining 2Kbit total capacity and identical electrical timing parameters. These variants are suitable for applications requiring the specific dual-die configuration.

All substitute parts are manufactured by Microchip Technology and maintain active product status with ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can 24AA02-I/P be used as a direct replacement for 24AA025-I/P?

A: Yes. Both parts share identical electrical specifications: 2Kbit capacity, 256 x 8 organization, 400 kHz I2C clock frequency, 900 ns access time, 5 ms write cycle time, 1.7V to 5.5V supply voltage, -40°C to 85°C operating temperature, and 8-DIP package. Direct substitution is supported at the circuit level.

Q: What is the difference between 24AA025-I/P and AT24HC02C-PUM?

A: Both parts provide 2Kbit I2C EEPROM functionality in 8-DIP packages with identical supply voltage and operating temperature ranges. AT24HC02C-PUM operates at 1 MHz clock frequency with 550 ns access time, compared to 400 kHz and 900 ns for 24AA025-I/P. The enhanced performance of AT24HC02C-PUM requires circuit-level confirmation of I2C bus compatibility at 1 MHz operation.

Q: Are the UID variants (24AA025UID-I/P, 24AA02UID-I/P) compatible with standard 24AA025-I/P applications?

A: UID variants maintain identical electrical timing and package specifications but feature dual-die memory organization (128 x 8 x 2) instead of single-die organization (256 x 8). Compatibility depends on application-specific requirements for memory addressing and organization. Electrical substitution is supported; functional compatibility requires design review.

Q: Do all substitute parts meet the same compliance standards as 24AA025-I/P?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All are active products manufactured by Microchip Technology with confirmed inventory availability.

Q: What is the significance of the 34AA02-I/P designation?

A: 34AA02-I/P is a parametric equivalent to 24AA025-I/P with identical electrical specifications and 8-DIP package. The designation reflects Microchip's product line differentiation. Electrical and functional substitution is fully supported.

Q: Can I use AT24HC02C-PUM in a legacy design specified for 24AA025-I/P?

A: AT24HC02C-PUM provides enhanced performance (1 MHz operation, 550 ns access time) while maintaining the same supply voltage, operating temperature range, and 8-DIP package. Substitution is supported provided the I2C bus and application firmware support 1 MHz clock frequency operation. No circuit modifications are required for pinout compatibility.
