Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by Microchip Technology and maintain active product status. Selection should be based on the following factors:

Standard Substitutes (24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 34AA02-I/P): These parts provide direct functional equivalence to the 24AA52-I/P with identical memory specifications, clock frequency, and access time. All are ROHS3 compliant and operate within the required temperature range. The 24AA02-I/P carries verified DiGi-Electronics programmable status. Supply voltage compatibility extends to 1.7V minimum, providing broader low-voltage application support.

Performance-Enhanced Substitute (AT24HC02C-PUM): This variant operates at 1 MHz clock frequency with 550 ns access time, delivering faster performance than the primary part. It maintains full functional compatibility with identical memory capacity and package configuration. This option is suitable for applications requiring higher I2C bus speeds while maintaining backward compatibility. Moisture sensitivity level is rated at 1 (Unlimited).

All parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8542.32.0051.

Frequently Asked Questions (FAQ)

Q: Can 24AA02-I/P directly replace 24AA52-I/P in existing designs?

A: Yes. Both parts share identical memory capacity (2Kbit), memory organization (256 x 8), I2C interface, clock frequency (400 kHz), access time (900 ns), package type (8-DIP), and operating temperature range (-40°C ~ 85°C). The 24AA02-I/P operates at 1.7V minimum supply voltage compared to 1.8V for the 24AA52-I/P, providing enhanced low-voltage compatibility.

Q: What is the difference between 24AA024-I/P and 24AA024H-I/P?

A: Both parts are functionally identical in all provided electrical and mechanical parameters. They share the same memory specifications, clock frequency, access time, voltage range, temperature range, and 8-DIP package configuration. Selection between these variants should be based on availability and procurement requirements.

Q: Is AT24HC02C-PUM compatible with 24AA52-I/P applications?

A: Yes, with performance enhancement. The AT24HC02C-PUM maintains identical memory capacity, organization, and package type. It operates at 1 MHz clock frequency (versus 400 kHz) with 550 ns access time (versus 900 ns), providing faster I2C communication. This part is suitable for applications that can benefit from higher bus speeds while maintaining full backward compatibility with the original design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the environmental compliance of the 24AA52-I/P.

Q: What is the minimum supply voltage for substitute parts?

A: The 24AA52-I/P operates at 1.8V minimum. Substitute parts 24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 34AA02-I/P, and AT24HC02C-PUM all operate at 1.7V minimum, providing broader low-voltage application support while maintaining full compatibility with designs specified for 1.8V and above.

Q: Can I use AT24HC02C-PUM in a 400 kHz I2C bus application?

A: Yes. The AT24HC02C-PUM operates at 1 MHz maximum clock frequency, which is backward compatible with 400 kHz I2C bus specifications. The part will function correctly at lower clock speeds.
