Substitute Part Grouping Explanation

Substitution eligibility for the AT24C02-10PC is determined by the following critical parameters:

  • Memory capacity: 2Kbit with 256 x 8 organization
  • Interface protocol: I2C serial communication
  • Package form factor: 8-DIP through-hole configuration
  • Electrical compatibility: Supply voltage and operating temperature ranges

Substitute parts must maintain identical memory size, organization, and I2C interface. Package and mounting type must be identical to ensure direct board-level replacement without layout modifications. Operating temperature range and supply voltage specifications determine application suitability; parts with wider or equivalent ranges are acceptable substitutes.

The following active production parts meet these substitution criteria:

  • 24AA02/P: Active status, wider supply voltage range (1.7V ~ 5.5V), RoHS3 compliant
  • 24C02C/P: Active status, equivalent 400 kHz operation, RoHS3 compliant
  • 24C02C-I/P: Active status, equivalent 400 kHz operation, extended temperature range (-40°C ~ 85°C), RoHS3 compliant
  • 24C02C-E/P: Active status, reduced clock frequency (100 kHz), extended temperature range (-40°C ~ 125°C), RoHS3 compliant

Engineering Selection Recommendations

24AA02/P is suitable for applications requiring low-voltage operation down to 1.7V while maintaining 400 kHz I2C performance. This part offers the widest supply voltage compatibility and is RoHS3 compliant with active production status.

24C02C/P provides direct functional equivalence to the AT24C02-10PC with 400 kHz operation and identical temperature range. This part is RoHS3 compliant and actively produced with high inventory availability.

24C02C-I/P is recommended for applications requiring extended operating temperature range (-40°C to 85°C) while maintaining 400 kHz I2C performance. Faster write cycle time (1 ms) provides performance improvement over the original part. RoHS3 compliant with active production status.

24C02C-E/P is suitable for applications requiring maximum operating temperature range (-40°C to 125°C). Clock frequency is reduced to 100 kHz, making this part appropriate only for systems where lower I2C bus speed is acceptable. RoHS3 compliant with active production status.

All substitute parts maintain identical 8-DIP through-hole packaging and 2Kbit memory capacity with 256 x 8 organization, ensuring direct board-level replacement compatibility.

Frequently Asked Questions (FAQ)

Q: Can 24AA02/P replace AT24C02-10PC in all applications?

A: 24AA02/P is functionally compatible for I2C memory operations at 400 kHz with identical 2Kbit capacity and 8-DIP packaging. The wider supply voltage range (1.7V ~ 5.5V) provides additional flexibility. However, verify that your application's supply voltage and operating temperature requirements fall within the specified ranges.

Q: What is the difference between 24C02C/P and 24C02C-I/P?

A: Both parts operate at 400 kHz with identical memory capacity and packaging. The primary differences are operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) and write cycle time (1.5 ms versus 1 ms). Select 24C02C-I/P for applications requiring extended temperature operation or faster write performance.

Q: Why does 24C02C-E/P operate at 100 kHz instead of 400 kHz?

A: 24C02C-E/P is specified for 100 kHz I2C operation and offers the widest operating temperature range (-40°C ~ 125°C). This part is suitable only for applications where lower I2C bus speed is acceptable and extended temperature operation is required.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (24AA02/P, 24C02C/P, 24C02C-I/P, and 24C02C-E/P) are RoHS3 compliant. The original AT24C02-10PC is RoHS non-compliant.

Q: Will these parts work in through-hole PCB designs without modification?

A: Yes, all substitute parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging. Direct board-level replacement is possible without layout or footprint modifications.

Q: What inventory status should I consider for production?

A: All substitute parts are in active production with current inventory availability. 24C02C/P has the highest inventory level (3919 pcs), followed by 24C02C-E/P (2200 pcs), 24AA02/P (854 pcs), and 24C02C-I/P (1916 pcs).
