Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C01-10TI-2.7 is determined by the following critical parameters:

• Memory capacity (1Kbit) and organization (128 x 8)
• I2C serial interface protocol at 400 kHz operation
• Package type and form factor (8-TSSOP surface mount)
• Operating voltage range compatibility
• Operating temperature range (-40°C ~ 85°C)
• Access time and write cycle time specifications

The 24AA014H-I/ST qualifies as a direct substitute based on matching memory capacity, interface protocol, package type, and thermal operating range. This part demonstrates functional equivalence while offering improved electrical characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 24AA014H-I/ST is the qualified substitute for the AT24C01-10TI-2.7 based on the following factors:

Functional Equivalence: Both devices share identical memory capacity (1Kbit), organization (128 x 8), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), and package configuration (8-TSSOP surface mount).

Improved Specifications: The 24AA014H-I/ST offers a reduced write cycle time of 5 ms compared to 10 ms on the original part, and an extended lower voltage supply limit of 1.7V versus 2.7V, providing greater operational flexibility.

Active Product Status: The 24AA014H-I/ST maintains active manufacturing status, ensuring long-term availability and supply chain continuity.

Compliance Enhancement: The 24AA014H-I/ST is ROHS3 compliant, addressing regulatory requirements that the obsolete AT24C01-10TI-2.7 does not meet.

Thermal Compatibility: Both parts operate across the identical temperature range (-40°C ~ 85°C), ensuring thermal performance parity in target applications.

Frequently Asked Questions (FAQ)

Q: Can the 24AA014H-I/ST directly replace the AT24C01-10TI-2.7 in existing designs?

A: Yes. Both devices feature identical memory capacity, I2C interface protocol, clock frequency, access time, and 8-TSSOP package configuration. Pin-to-pin compatibility and functional equivalence are confirmed.

Q: What is the significance of the reduced write cycle time in the 24AA014H-I/ST?

A: The 24AA014H-I/ST write cycle time of 5 ms is half that of the AT24C01-10TI-2.7 (10 ms). This improvement reduces the time required for page write operations, potentially enhancing system throughput in applications performing frequent memory updates.

Q: Does the extended voltage range of the 24AA014H-I/ST affect compatibility?

A: No. The 24AA014H-I/ST voltage range of 1.7V ~ 5.5V encompasses the original part's 2.7V ~ 5.5V specification. Designs operating within the original voltage window remain fully compatible.

Q: Why is RoHS compliance important for this substitution?

A: RoHS3 compliance on the 24AA014H-I/ST ensures conformance to current environmental and regulatory standards for electronic components. This is critical for applications subject to regulatory requirements or customer specifications mandating RoHS compliance.

Q: Are there any package or mounting differences between these parts?

A: No. Both the AT24C01-10TI-2.7 and 24AA014H-I/ST use identical 8-TSSOP surface mount packaging with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes require no modification.

Q: What is the inventory status of the substitute part?

A: The 24AA014H-I/ST is available with 869 pieces in new original stock, providing immediate procurement availability compared to the obsolete AT24C01-10TI-2.7.
