Engineering Selection Recommendations

Direct Equivalents (Identical Specifications): No substitute parts possess identical specifications to the 24C02C-I/MS across all parameters. The 24C02C-I/MS maintains a unique combination of 400 kHz operation, 1 ms write cycle time, and 4.5V minimum supply voltage.

Enhanced Capability Substitutes (Backward Compatible):

24LC024-I/MS and 24LC02B-I/MS are suitable substitutes when the design permits operation at lower supply voltages (2.5V minimum). Both maintain 400 kHz clock frequency and 900 ns access time. The 24LC024-I/MS is verified as programmable by DiGi-Electronics and carries MSL 2 rating, while 24LC02B-I/MS is not verified.

24LC024H-I/MS and 34LC02-I/MS support higher clock frequencies (1 MHz) and faster access times (400 ns), providing performance headroom. Both operate at reduced minimum supply voltages (2.5V and 2.2V respectively). The 24LC024H-I/MS is verified programmable; 34LC02-I/MS is not verified.

24AA02-I/MS and 24AA025-I/MS extend the minimum supply voltage to 1.7V, enabling operation in low-power applications. Both maintain 400 kHz operation but specify 5 ms write cycle time. The 24AA025-I/MS is verified programmable; 24AA02-I/MS is not verified.

24C02C-E/MS operates at reduced clock frequency (100 kHz) but extends the maximum operating temperature to 125°C. This part is suitable only when lower clock speed is acceptable and extended temperature range is required.

BR24A02FVM-WMTR (Rohm Semiconductor) supports extended temperature range to 105°C and carries AEC-Q100 automotive qualification. Minimum supply voltage is 2.5V. Packaging is Tape & Reel format.

BR24G02FVJ-3AGTE2 (Rohm Semiconductor) operates at 1 MHz with extended voltage range (1.6V minimum) and is available in 8-TSSOP package. This part is not verified as programmable.

BR24G02FVJ-3GTE2 (Rohm Semiconductor) is marked "Not For New Designs" and should not be selected for new applications despite meeting functional requirements.

Selection Criteria:

For designs requiring 4.5V minimum supply voltage with 1 ms write cycle: 24C02C-I/MS remains the only option.
For designs permitting 2.5V operation: 24LC024-I/MS or 24LC024H-I/MS are preferred (verified programmable).
For automotive applications: BR24A02FVM-WMTR with AEC-Q100 qualification.
For low-voltage applications: 24AA025-I/MS (1.7V minimum, verified) or BR24G02FVJ-3AGTE2 (1.6V minimum).
For extended temperature: 24C02C-E/MS (125°C) or BR24A02FVM-WMTR (105°C).

Frequently Asked Questions (FAQ)

Q: Can 24LC024-I/MS replace 24C02C-I/MS in all applications?

A: 24LC024-I/MS is compatible when the design operates at supply voltages of 2.5V or higher. The 24C02C-I/MS requires minimum 4.5V, so 24LC024-I/MS cannot be used in designs that depend on the higher voltage minimum specification. Both share identical memory capacity, organization, I2C interface, 400 kHz clock frequency, and 900 ns access time. The primary difference is the 5 ms write cycle time versus 1 ms on the original part.

Q: What is the difference between 24LC024H-I/MS and 24LC024-I/MS?

A: Both parts are Microchip 2Kbit I2C EEPROM devices in 8-MSOP packages with 2.5V ~ 5.5V supply range. The 24LC024H-I/MS operates at 1 MHz clock frequency with 400 ns access time, while 24LC024-I/MS operates at 400 kHz with 900 ns access time. The "H" designation indicates high-speed operation. Both specify 5 ms write cycle time. Selection depends on whether the application requires faster I2C communication speeds.

Q: Are Rohm Semiconductor parts (BR24A02FVM-WMTR, BR24G02FVJ-3AGTE2) compatible with Microchip parts?

A: Yes, Rohm parts are functionally compatible when electrical specifications align. BR24A02FVM-WMTR matches 400 kHz operation and extends temperature to 105°C with automotive qualification. BR24G02FVJ-3AGTE2 operates at 1 MHz with extended voltage range (1.6V minimum). Both are available in Tape & Reel packaging. Verify that your application design accommodates the specific voltage and temperature ranges of the selected Rohm device.

Q: Why does 24C02C-E/MS have different specifications?

A: The 24C02C-E/MS is a variant of the 24C02C series with reduced clock frequency (100 kHz instead of 400 kHz) and extended maximum operating temperature (125°C instead of 85°C). This part is suitable only when lower I2C communication speed is acceptable and the application requires operation at temperatures above 85°C. The voltage supply range remains 4.5V ~ 5.5V.

Q: What does "Not For New Designs" mean for BR24G02FVJ-3GTE2?

A: This designation indicates the part is in mature or end-of-life status and Rohm Semiconductor does not recommend its use in new product designs. While the part may still be available and functionally compatible, alternative parts such as BR24G02FVJ-3AGTE2 should be selected for new applications to ensure long-term supply availability and manufacturer support.

Q: Can I use 24AA02-I/MS in a design that requires 4.5V minimum supply voltage?

A: No. The 24AA02-I/MS specifies a minimum supply voltage of 1.7V, which means it is designed for low-voltage operation. While it will function at 4.5V (within its 1.7V ~ 5.5V range), it is not qualified or tested for designs that require a 4.5V minimum threshold. The 24C02C-I/MS is the appropriate choice for applications with 4.5V minimum supply requirements.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings?

A: MSL indicates the maximum time a component can be exposed to ambient conditions before soldering. MSL 1 (Unlimited) means the part has no time restriction and can be stored indefinitely at room temperature. MSL 2 (1 Year) requires the part to be soldered within one year of the manufacturing date if exposed to ambient conditions. The 24C02C-I/MS carries MSL 1, while 24LC024-I/MS carries MSL 2. For applications with extended storage requirements, MSL 1 parts are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed in this document are RoHS3 compliant. This ensures compatibility with environmental regulations and procurement requirements across all listed alternatives.
