AT24C04-10PI Equivalent & Substitute Parts

Part Overview

The AT24C04-10PI is a 4Kbit EEPROM memory IC with I2C interface operating at 400 kHz, manufactured by Microchip Technology in 8-DIP through-hole packaging. This part is classified as obsolete and has been superseded by newer alternatives. Finding equivalent substitute parts is necessary due to discontinued production status and the need for continued system support and new designs requiring active, readily available components.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT24C04-10PI is determined by the following critical parameters:

Memory capacity (4Kbit), memory format (EEPROM), and I2C interface compatibility are the primary functional requirements. The 8-DIP through-hole package and pin configuration must match for direct board-level replacement. Clock frequency (400 kHz) and access time (900 ns) define operational performance boundaries. Operating temperature range (-40°C ~ 85°C) and supply voltage compatibility establish environmental and electrical constraints.

The 24AA04-I/P meets these substitution criteria with identical memory capacity, interface type, package configuration, and performance specifications. The key distinction is the expanded supply voltage range (1.7V ~ 5.5V) in the substitute part, which provides broader operational flexibility while maintaining full compatibility with the original 4.5V ~ 5.5V requirement.

Parameter Comparison

Engineering Selection Recommendations

The 24AA04-I/P is the manufacturer-recommended substitute for the AT24C04-10PI. The substitute part carries Active product status with ROHS3 compliance, whereas the original part is Obsolete and RoHS non-compliant. For new designs and ongoing production requiring 4Kbit I2C EEPROM functionality in 8-DIP packaging, the 24AA04-I/P provides equivalent electrical and mechanical performance with improved regulatory compliance and assured supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 24AA04-I/P directly replace the AT24C04-10PI on existing PCBs?

A: Yes. Both parts use identical 8-DIP through-hole packaging with matching pin configurations. No PCB modifications are required for direct substitution.

Q: Are there functional differences between these parts?

A: No functional differences exist. Both parts provide 4Kbit EEPROM storage with I2C interface, 400 kHz clock frequency, 900 ns access time, and 5ms write cycle time. The 24AA04-I/P supports a wider supply voltage range (1.7V ~ 5.5V versus 4.5V ~ 5.5V), which is a superset of the original specification.

Q: What is the significance of the product status difference?

A: The AT24C04-10PI is classified as Obsolete, indicating discontinued manufacturing. The 24AA04-I/P is Active, ensuring continued availability and supply chain reliability for current and future applications.

Q: Does the substitute part meet current compliance requirements?

A: Yes. The 24AA04-I/P is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original AT24C04-10PI is RoHS non-compliant.

Q: Are there any package or pinout considerations?

A: Both parts use 8-PDIP packaging with 0.300" (7.62mm) spacing. Pinout is identical, enabling direct board-level replacement without design modifications.
