AT24C01-10PI EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The AT24C01-10PI is a 1Kbit EEPROM memory IC utilizing I2C interface technology, manufactured by Microchip Technology. This component operates at 400 kHz clock frequency with 900 ns access time and is housed in an 8-DIP package. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. Equivalent parts must maintain functional compatibility across memory capacity, interface protocol, and electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C01-10PI is determined by strict alignment with the following critical parameters:

Memory Specifications: Memory size must be 1Kbit with 128 x 8 organization. Memory interface must be I2C protocol. Clock frequency must support 400 kHz operation. Access time must not exceed 900 ns.

Electrical Compatibility: Supply voltage range must encompass or be compatible with the 4.5V ~ 5.5V requirement. Operating temperature range must cover -40°C ~ 85°C.

Physical Compatibility: Package must be 8-DIP with 0.300" (7.62mm) pitch. Mounting type must be through-hole.

The identified substitute parts meet these core requirements while offering variations in write cycle time and supply voltage flexibility. Substitutes are classified as direct manufacturer alternatives or parametric equivalents based on their operational characteristics and product status.

Parameter Comparison

Engineering Selection Recommendations

24AA014H-I/P is classified as a direct manufacturer alternative. This part maintains full functional compatibility with the AT24C01-10PI across all core memory and interface parameters. The 24AA014H-I/P offers extended supply voltage range (1.7V ~ 5.5V) and improved write cycle time (5 ms versus 10 ms). The part carries active product status and ROHS3 compliance, making it suitable for new designs and legacy system replacements where supply voltage flexibility is beneficial.

24C01C-I/P is classified as a parametric equivalent. This part matches all critical memory, interface, and electrical specifications of the AT24C01-10PI. The 24C01C-I/P provides the fastest write cycle time (1 ms) among available substitutes. The part carries active product status and ROHS3 compliance. Selection of this part is appropriate when write performance optimization is required within the 4.5V ~ 5.5V supply voltage constraint.

Both substitute parts are manufactured by Microchip Technology and maintain identical package geometry and through-hole mounting characteristics, enabling direct physical replacement in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 24AA014H-I/P replace the AT24C01-10PI in all applications?

A: The 24AA014H-I/P maintains functional compatibility across memory capacity, organization, interface protocol, clock frequency, and access time. The extended supply voltage range (1.7V ~ 5.5V) provides broader operational flexibility. Direct physical replacement is possible due to identical 8-DIP package geometry. Verify that your application does not depend on the specific write cycle time of 10 ms; the 24AA014H-I/P operates at 5 ms.

Q: What is the primary difference between the two substitute parts?

A: The 24AA014H-I/P and 24C01C-I/P differ in write cycle time and supply voltage range. The 24AA014H-I/P supports 1.7V ~ 5.5V operation with 5 ms write time. The 24C01C-I/P operates at 4.5V ~ 5.5V with 1 ms write time. Both maintain identical memory specifications and I2C interface characteristics.

Q: Are both substitute parts available in the same packaging as the original?

A: Yes. Both the 24AA014H-I/P and 24C01C-I/P are supplied in 8-DIP packages with 0.300" (7.62mm) pitch, matching the AT24C01-10PI package specification. Through-hole mounting compatibility is maintained.

Q: What compliance certifications apply to the substitute parts?

A: Both substitute parts carry ROHS3 compliance and REACH unaffected status. The original AT24C01-10PI is RoHS non-compliant. Selection of either substitute part satisfies modern environmental and regulatory requirements.

Q: Can I use these parts interchangeably in my design?

A: Physical interchangeability is confirmed due to identical package and pinout. Functional interchangeability depends on your application's tolerance for write cycle time variation. If your design requires the 10 ms write cycle time of the original part, neither substitute is appropriate. If your design accommodates faster write cycles, both substitutes are functionally compatible.
