24C01CT-I/MNY EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24C01CT-I/MNY is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 8-TDFN (2x3) surface mount packaging. This non-volatile memory device is designed for applications requiring small-capacity data storage with low-power consumption and standard I2C bus compatibility. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits operation within broader electrical parameter ranges. The following equivalent devices maintain core functional compatibility while offering variations in supply voltage ranges, access timing, and packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C01CT-I/MNY is determined by the following critical parameters:

Core Functional Requirements (Non-Negotiable):

• Memory capacity: 1Kbit
• Memory organization: 128 x 8
• Interface protocol: I2C
• Clock frequency: 400 kHz
• Package: 8-TDFN (2x3)
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount

Variable Parameters (Allowable Differences):

• Supply voltage range (main part: 4.5V ~ 5.5V; substitutes may support wider ranges: 1.7V ~ 5.5V or 2.5V ~ 5.5V)
• Access time (main part: 900 ns; substitutes may vary: 900 ns to 4.6 µs)
• Write cycle time (main part: 1ms; substitutes may vary: 5ms)
• Packaging format (Cut Tape vs. Tape & Reel)

All substitute parts listed maintain identical memory specifications, I2C protocol compatibility, and thermal operating range, ensuring functional interchangeability within systems designed for the 24C01CT-I/MNY.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with full RoHS3 compliance and REACH unaffected certification, matching the regulatory compliance profile of the 24C01CT-I/MNY.

24AA014T-I/MNY: Supports extended lower supply voltage operation (1.7V minimum) while maintaining identical access time (900 ns) and I2C protocol compatibility. Suitable for applications requiring broader voltage tolerance. Cut Tape packaging format.

24AA01HT-I/MNY: Provides extended lower supply voltage operation (1.7V minimum) with highest available inventory (4698 Pcs). Tape & Reel packaging format accommodates high-volume production environments. Identical access time specification (900 ns).

24LC01BHT-I/MNY: Offers highest inventory availability (10120 Pcs) with moderate supply voltage range (2.5V ~ 5.5V). Cut Tape packaging. Maintains 900 ns access time specification.

24LC01BT-I/MNY: Supports 2.5V ~ 5.5V supply voltage range with extended access time specification (4.6 µs). Cut Tape packaging. Suitable for applications where slower access timing is acceptable.

Selection should prioritize inventory availability, required supply voltage range, and packaging format compatibility with production equipment.

Frequently Asked Questions (FAQ)

Q: Can 24AA014T-I/MNY replace 24C01CT-I/MNY in a 5V system? A: Yes. The 24AA014T-I/MNY supports 1.7V ~ 5.5V supply voltage range, encompassing the original part's 4.5V ~ 5.5V range. I2C protocol, memory capacity, and package specifications are identical. The extended write cycle time (5ms vs. 1ms) must be accommodated in system timing requirements.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) packaging provides individual component strips suitable for manual assembly or small-batch production. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Electrical and functional specifications remain identical.

Q: Are all substitute parts compatible with existing PCB designs? A: Yes. All substitute parts use identical 8-TDFN (2x3) package geometry and pin configuration, ensuring direct PCB footprint compatibility without layout modifications.

Q: Does the 24LC01BT-I/MNY's 4.6 µs access time affect system performance? A: The 24LC01BT-I/MNY maintains 400 kHz I2C clock frequency compatibility. The extended access time (4.6 µs vs. 900 ns) represents internal memory response timing and does not impact I2C bus protocol operation. System compatibility depends on application-specific timing requirements.

Q: Which substitute offers the best supply voltage flexibility? A: The 24AA014T-I/MNY and 24AA01HT-I/MNY both support 1.7V ~ 5.5V supply voltage range, providing maximum lower-voltage operation capability. The 24AA01HT-I/MNY offers superior inventory availability (4698 Pcs).

Q: Are all parts RoHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected certification status, matching regulatory requirements of the primary 24C01CT-I/MNY device.
