24LC024T-E/MC EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC024T-E/MC is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, packaged in 8-DFN (2x3) with tape and reel packaging. This non-volatile memory device operates at 400 kHz I2C clock frequency with 900 ns access time and supports supply voltages from 2.5V to 5.5V across an operating temperature range of -40°C to 125°C. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for specific assembly processes, or when design requirements necessitate different operating temperature ranges or supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC024T-E/MC is determined by the following critical parameters:

Core Functional Requirements:

• Memory capacity: 2Kbit (256 x 8 organization)
• Interface protocol: I2C
• Memory type: Non-volatile EEPROM

Electrical Compatibility:

• I2C clock frequency: 400 kHz minimum support
• Access time: 900 ns or faster
• Write cycle time: 5ms or faster
• Supply voltage range: Must encompass or exceed 2.5V ~ 5.5V

Environmental & Compliance:

• Operating temperature range: Must support -40°C minimum and 125°C maximum, or be suitable for the intended application temperature window
• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

Physical Considerations:

• Mounting type: Surface mount
• Package format: 8-pin DFN-family packages (VFDFN, UFDFN, WFDFN, TDFN, MLP variants acceptable)

Substitute parts meeting these criteria are functionally interchangeable at the system level, though package dimensions and pin configurations may vary within the DFN family.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, meeting baseline regulatory and supply chain requirements.

Temperature Range Consideration: The 24LC024T-E/MC supports -40°C to 125°C operation. Substitute parts BR24L02NUX-WTR, CAT34C02VP2IGT4A, M24C02-FMC6TG, and M24C02-RMC6TG are rated to -40°C to 85°C maximum. The M24C02-DRMF3TG/K maintains the full -40°C to 125°C range, matching the primary part specification.

Supply Voltage Range: All substitute parts support extended voltage ranges (1.7V to 1.8V minimum) that exceed the 2.5V minimum of the primary part, providing broader operational flexibility.

Clock Frequency and Performance: The M24C02-DRMF3TG/K operates at 1 MHz with 450 ns access time, exceeding the 400 kHz / 900 ns specification of the primary part. All other substitutes maintain 400 kHz operation with 900 ns access time, matching the primary part exactly.

Package Variants: All substitute parts use 8-pin DFN-family packages (UFDFN, WFDFN, TDFN, MLP) with exposed pads. Physical dimensions within the DFN family are similar but not identical; PCB layout verification is necessary when changing package variants.

Automotive Qualification: The M24C02-DRMF3TG/K carries AEC-Q100 automotive qualification. This part is suitable for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into a design using the 24LC024T-E/MC?

A: All listed parts are functionally equivalent at the I2C protocol level, supporting 2Kbit EEPROM storage with 256 x 8 organization. However, package dimensions vary within the DFN family. Physical PCB layout compatibility must be verified before substitution. Pin assignments are consistent across I2C EEPROM devices in this category.

Q: What is the difference between the various DFN package types listed?

A: VFDFN, UFDFN, WFDFN, TDFN, and MLP are all 8-pin DFN-family packages with 2x3 mm footprints. Differences exist in body dimensions, lead frame design, and thermal characteristics. Consult manufacturer datasheets for precise footprint specifications before PCB redesign.

Q: Does the M24C02-DRMF3TG/K's higher clock frequency (1 MHz) affect compatibility?

A: No. The 1 MHz capability is backward compatible with 400 kHz I2C bus operation. The device operates at the bus speed dictated by the master controller. Higher clock frequency capability does not create incompatibility with 400 kHz systems.

Q: Why do some substitutes have lower maximum operating temperatures (85°C vs. 125°C)?

A: Operating temperature range is a manufacturing specification determined by device design and qualification testing. Applications requiring operation above 85°C must use the 24LC024T-E/MC or M24C02-DRMF3TG/K. For applications with maximum ambient temperatures below 85°C, all listed parts are suitable.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts do not require special moisture control during storage or handling, and shelf life is unlimited under normal conditions.
