AT24C04-10PC Equivalent & Substitute Parts Reference

Part Overview

The AT24C04-10PC by Microchip Technology is a non-volatile EEPROM memory IC providing 4Kbit capacity with an I2C interface, designed for through-hole applications in an 8-DIP (0.300", 7.62mm) package. This device operates at a clock frequency of 400 kHz, features an access time of 900 ns, and supports a voltage supply from 4.5V to 5.5V within a 0°C to 70°C temperature range. It is classified as obsolete, making it necessary to identify substitute EEPROM memory ICs with matching or compatible electrical, mechanical, and compliance characteristics for drop-in replacement or design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AT24C04-10PC is based strictly on matching the following key parameters: memory type (EEPROM), memory size (4Kbit), interface type (I2C), clock frequency (400 kHz), write cycle time (5 ms), access time (900 ns), supported supply voltage range, mechanical package (8-DIP 0.300", 7.62mm), and through-hole mounting. Product status and compliance certifications are considered for material control and regulatory alignment. Substitute part 24AA04-I/P by Microchip Technology meets these requirements as presented in the input data.

Parameter Comparison

Engineering Selection Recommendations

The AT24C04-10PC memory IC is obsolete and RoHS non-compliant, while the substitute 24AA04-I/P is active and ROHS3 compliant. Both are REACH unaffected and have the same ECCN and HTSUS codes. Selection may be driven by sourcing policy favoring devices with active status and RoHS compliance for environments or designs requiring such certifications. All other assessed parameters directly match or exceed requirements based on the input data.

Frequently Asked Questions (FAQ)

Q1: How is a compatible EEPROM memory IC substitute identified in this category?
A: By matching memory type (EEPROM), memory size (4Kbit), interface type (I2C), clock frequency, timing parameters, supply voltage range, mechanical package, and compliance certifications as provided.

Q2: What packaging factors must be considered for substitution?
A: The substitute must be in the 8-DIP (0.300", 7.62mm) package with through-hole mounting to ensure direct compatibility with existing PCB footprints.

Q3: Are there differences in compliance status between AT24C04-10PC and 24AA04-I/P?
A: Yes. The AT24C04-10PC is RoHS non-compliant, while 24AA04-I/P is ROHS3 compliant. Both are REACH unaffected.

Q4: How does product status affect substitute selection?
A: Product status is essential for supply continuity. AT24C04-10PC is obsolete, making its substitute, the active 24AA04-I/P, necessary for ongoing procurement.

Q5: Can the 24AA04-I/P be used in the same applications as AT24C04-10PC?
A: Based on the input, all key parameters required for direct substitution are matched or exceeded, including package, interface, and electrical ratings.
