Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24AA02H-I/P are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical 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. These parts are direct functional replacements with no performance trade-offs.

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 physical and electrical envelope.

The critical parameters determining substitution eligibility are: memory capacity (2Kbit), memory format (EEPROM), interface type (I2C), package type (8-DIP), supply voltage compatibility (1.7V ~ 5.5V), and operating temperature range (-40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents: The parts 24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 24AA025UID-I/P, 24AA02UID-I/P, and 34AA02-I/P are functionally equivalent to the 24AA02H-I/P. All maintain identical electrical performance specifications and package configuration. Selection among these equivalents may be based on inventory availability and product status verification. The 24AA02-I/P carries DiGi-Electronics Programmable Verified status, providing additional validation for critical applications.

Enhanced Performance Alternative: The AT24HC02C-PUM operates at 1 MHz clock frequency with 550 ns access time, representing a performance upgrade while maintaining full electrical and mechanical compatibility. This part is suitable for applications requiring faster I2C communication or reduced access latency. The AT24HC02C-PUM carries MSL 1 (Unlimited) rating and maintains ROHS3 compliance. Selection of this part introduces no functional incompatibility but provides improved timing characteristics.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical supply voltage and operating temperature ranges. Through-hole 8-DIP package configuration is consistent across all options, ensuring direct socket compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AT24HC02C-PUM replace the 24AA02H-I/P in existing designs?

A: Yes. The AT24HC02C-PUM maintains identical supply voltage (1.7V ~ 5.5V), operating temperature (-40°C ~ 85°C), memory capacity (2Kbit), I2C interface, and 8-DIP package configuration. The elevated clock frequency (1 MHz vs. 400 kHz) and faster access time (550 ns vs. 900 ns) represent performance improvements with no backward compatibility issues.

Q: What is the difference between 24AA02-I/P and 24AA02H-I/P?

A: Both parts share identical electrical specifications: 2Kbit EEPROM, I2C 400 kHz, 900 ns access time, 256 x 8 organization, and 8-DIP package. The primary distinction is the DiGi-Electronics Programmable Verified status of the 24AA02-I/P, indicating additional validation for programmable applications.

Q: Are the UID variants (24AA02UID-I/P, 24AA025UID-I/P) compatible substitutes?

A: Yes. The UID variants maintain 2Kbit capacity, I2C 400 kHz interface, 900 ns access time, 1.7V ~ 5.5V supply voltage, -40°C ~ 85°C operating temperature, and 8-DIP package. The memory organization differs (128 x 8 x 2 vs. 256 x 8), but total capacity remains 2Kbit, ensuring functional compatibility in I2C-based applications.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the 24AA02H-I/P compliance profile. The AT24HC02C-PUM carries MSL 1 (Unlimited) moisture sensitivity rating, while other parts list MSL as Not Applicable.

Q: Which substitute part offers the best availability?

A: The AT24HC02C-PUM currently maintains the highest inventory level at 6136 pieces. Among parametric equivalents, the 34AA02-I/P offers 2923 pieces in stock.
