Equivalent & Substitute Parts for 24C01CT-I/OT

Part Overview

The 24C01CT-I/OT is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface communication at 400 kHz with 900 ns access time. This component is packaged in SOT-23-6 surface mount configuration and operates across the industrial temperature range of -40°C to 85°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and interface protocol.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C01CT-I/OT is determined by strict equivalence in the following parameters: memory capacity (1Kbit), memory organization (128 x 8), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), SOT-23-6 package footprint, and surface mount configuration. All identified substitutes maintain these core electrical and mechanical specifications. Voltage supply range variations are permitted when the substitute part's minimum voltage specification does not exceed the main part's minimum, and the substitute's maximum voltage specification meets or exceeds the main part's maximum. Write cycle time differences do not preclude substitution when all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both 24AA014T-I/OT and 24LC014T-I/OT are valid substitutes for the 24C01CT-I/OT based on electrical equivalence and mechanical compatibility. All three parts maintain active product status and ROHS3 compliance. The 24AA014T-I/OT operates across an extended lower voltage range (1.7V minimum) compared to the main part (4.5V minimum), providing broader supply voltage flexibility. The 24LC014T-I/OT operates at 2.5V minimum, offering intermediate voltage range coverage. Selection between substitutes should be based on system voltage requirements and packaging format availability (Cut Tape versus Tape & Reel).

Frequently Asked Questions (FAQ)

Q: Can 24AA014T-I/OT replace 24C01CT-I/OT in all applications? A: Yes, provided the system supply voltage remains within the 24AA014T-I/OT operating range of 1.7V to 5.5V. The electrical specifications and package footprint are equivalent.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) packaging provides individual component strips, while Tape & Reel (TR) packaging supplies components on continuous reels. Both formats contain identical components; packaging format selection depends on assembly process requirements and order quantity.

Q: Are there voltage supply limitations when substituting parts? A: The substitute part's voltage range must encompass the application's operating voltage. The 24AA014T-I/OT (1.7V ~ 5.5V) accommodates broader voltage applications than the main part (4.5V ~ 5.5V).

Q: Do write cycle time differences affect substitution compatibility? A: Write cycle time variations (1ms for 24C01CT-I/OT versus 5ms for substitutes) do not prevent substitution when all other electrical and mechanical parameters remain equivalent. Application timing requirements should be verified independently.

Q: Is the SOT-23-6 package footprint identical across all three parts? A: Yes, all three parts use SOT-23-6 surface mount packaging with identical mechanical specifications and PCB footprint requirements.
