AT24C02-10PI EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The AT24C02-10PI is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, housed in an 8-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates at 400 kHz I2C clock frequency with 900 ns access time and requires a 4.5V to 5.5V supply voltage. Substitutes must maintain functional compatibility across memory capacity, interface protocol, and package form factor while accommodating variations in operating temperature ranges and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across five critical dimensions: memory capacity (2Kbit), memory organization (256 x 8), interface protocol (I2C), package form factor (8-DIP through-hole), and electrical compatibility. The main part AT24C02-10PI operates at 400 kHz with 900 ns access time and requires 4.5V to 5.5V supply voltage.

Substitute parts are grouped by their deviation from these core parameters:

Group 1 - Full Parameter Match (Preferred): Parts maintaining 400 kHz clock frequency, 900 ns access time, 4.5V to 5.5V supply range, and -40°C to 85°C operating temperature. These parts are direct functional replacements with identical electrical performance.

Group 2 - Voltage Range Extension: Parts supporting wider supply voltage ranges (1.7V to 5.5V) while maintaining all other electrical parameters. These parts are backward compatible and offer enhanced flexibility for low-power applications.

Group 3 - Clock Frequency Reduction: Parts operating at 100 kHz instead of 400 kHz. These parts maintain 2Kbit capacity and I2C interface but operate at reduced speed, suitable for applications with relaxed timing requirements.

Group 4 - Temperature Range Variation: Parts with different operating temperature specifications. These parts maintain core electrical parameters but differ in thermal operating envelope.

All substitute parts maintain identical package form factor (8-DIP), mounting type (through-hole), and memory organization (256 x 8).

Parameter Comparison

Engineering Selection Recommendations

24C02C-I/P is the primary substitute for AT24C02-10PI. This part maintains identical electrical parameters (400 kHz clock frequency, 900 ns access time, 4.5V to 5.5V supply range, -40°C to 85°C operating temperature) and package form factor. The part is active in production status and ROHS3 compliant, providing long-term availability and regulatory compliance advantages over the obsolete original part.

24AA024H-I/P is a secondary substitute offering extended supply voltage range (1.7V to 5.5V) while maintaining all other electrical parameters and operating temperature range. This part is suitable for applications requiring low-voltage operation or enhanced supply flexibility. ROHS3 compliance and active production status ensure availability.

24C02C/P is a manufacturer-recommended substitute with identical clock frequency and supply voltage specifications. However, this part operates within a narrower temperature range (0°C to 70°C) compared to the original part (-40°C to 85°C). Selection of this part requires verification that the application does not require extended low-temperature operation below 0°C.

24C02C-E/P operates at reduced clock frequency (100 kHz) and extended access time (4.6 µs). This part is suitable only for applications with relaxed timing requirements that do not depend on 400 kHz I2C operation. The part offers extended operating temperature range (-40°C to 125°C), which may be beneficial for high-temperature applications. ROHS3 compliance and active production status are confirmed.

All substitute parts are manufactured by Microchip Technology and maintain identical package form factor and through-hole mounting type, ensuring direct mechanical compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can 24C02C-I/P be used as a direct replacement for AT24C02-10PI?

A: Yes. The 24C02C-I/P maintains identical electrical parameters including 400 kHz clock frequency, 900 ns access time, 4.5V to 5.5V supply voltage, and -40°C to 85°C operating temperature. The 8-DIP package and through-hole mounting are identical. This part is the recommended substitute.

Q: What is the difference between 24AA024H-I/P and 24C02C-I/P?

A: The 24AA024H-I/P supports a wider supply voltage range (1.7V to 5.5V) compared to 24C02C-I/P (4.5V to 5.5V). All other electrical parameters are identical. The 24AA024H-I/P is suitable for applications requiring low-voltage operation.

Q: Why does 24C02C/P have a narrower operating temperature range?

A: The 24C02C/P operates from 0°C to 70°C, which is narrower than the original AT24C02-10PI range of -40°C to 85°C. This part is suitable only for applications that do not require operation below 0°C or above 70°C.

Q: Can I use 24C02C-E/P in place of AT24C02-10PI?

A: The 24C02C-E/P operates at 100 kHz clock frequency instead of 400 kHz. This part is compatible only with applications that do not require 400 kHz I2C operation. Verify that your I2C bus timing requirements are satisfied at 100 kHz before selecting this part.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts (24AA024H-I/P, 24C02C-E/P, 24C02C/P, 24C02C-I/P) are ROHS3 compliant. The original AT24C02-10PI is RoHS non-compliant. Substitution provides regulatory compliance improvement.

Q: Do all substitute parts use the same 8-DIP package?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) package with through-hole mounting. Direct PCB compatibility is maintained without layout modifications.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with confirmed inventory: 24AA024H-I/P (1784 pcs), 24C02C-E/P (2200 pcs), 24C02C/P (3919 pcs), and 24C02C-I/P (1916 pcs) are available as new original stock.
