Equivalent & Substitute Parts for 24LC025-E/MC

Part Overview

The 24LC025-E/MC is a 2Kbit EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates via I2C interface at 400 kHz clock frequency and is housed in an 8-DFN (2x3) surface mount package. The part is currently active in production with 988 pieces available in inventory. The 24LC025-E/MC is ROHS3 compliant and carries unlimited moisture sensitivity level rating.

Substitute parts are identified when equivalent memory capacity, interface protocol, and electrical operating parameters align with the original specification, enabling direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC025-E/MC are qualified based on the following criteria:

Core Functional Parameters (Must Match):

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

Electrical Compatibility Parameters (Must Support):

• Supply voltage range must encompass or exceed 2.5V ~ 5.5V
• Clock frequency must support 400 kHz operation
• Access time and write cycle time must meet or exceed performance specifications

Physical and Compliance Parameters:

• Surface mount technology
• 8-pin package configuration (2x3 footprint)
• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)

The three substitute parts listed below meet these criteria through STMicroelectronics M24C02 series devices, which provide equivalent 2Kbit I2C EEPROM functionality with enhanced or equivalent electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

M24C02-DRMF3TG/K (STMicroelectronics): This substitute provides enhanced performance with 1 MHz clock frequency capability and 450 ns access time, both superior to the 24LC025-E/MC baseline. The part maintains full temperature range operation (-40°C ~ 125°C) and extended supply voltage support (1.8V ~ 5.5V). AEC-Q100 automotive qualification is included. Package configuration is 8-MLP (2x3), which differs from the original 8-DFN but maintains identical footprint dimensions. This option is suitable for applications requiring higher I2C bus speeds while maintaining backward compatibility at 400 kHz operation.

M24C02-FMC6TG (STMicroelectronics): This substitute matches the 24LC025-E/MC at 400 kHz clock frequency and 900 ns access time, providing direct functional equivalence. Supply voltage range extends to 1.7V minimum. Operating temperature range is reduced to -40°C ~ 85°C. Package type is 8-UFDFPN (2x3). This option is appropriate for applications operating within the reduced temperature range where cost optimization or inventory availability is a consideration.

M24C02-RMC6TG (STMicroelectronics): This substitute provides identical electrical performance to the 24LC025-E/MC at 400 kHz clock frequency and 900 ns access time. Supply voltage range is 1.8V ~ 5.5V. Operating temperature range is -40°C ~ 85°C. Package type is 8-UFDFPN (2x3). This option is suitable for applications where the reduced upper temperature limit is acceptable and where the 8-UFDFPN package footprint is compatible with circuit board design.

All three substitutes are ROHS3 compliant, carry unlimited MSL rating, and maintain active production status with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can M24C02-DRMF3TG/K operate at the same 400 kHz I2C speed as the 24LC025-E/MC?

A: Yes. The M24C02-DRMF3TG/K supports 1 MHz maximum clock frequency, which includes full compatibility with 400 kHz operation. The device is backward compatible with lower I2C bus speeds.

Q: What is the primary difference between the three M24C02 substitutes?

A: The three substitutes differ in package type (8-MLP versus 8-UFDFPN), operating temperature range (125°C maximum versus 85°C maximum), and minimum supply voltage (1.8V or 1.7V versus 2.5V). All three maintain 2Kbit capacity and I2C interface compatibility.

Q: Are the package footprints interchangeable between 8-DFN and 8-MLP?

A: Both 8-DFN and 8-MLP packages maintain 2x3 mm footprint dimensions and 8-pin configuration. Pin pitch and placement are identical. However, physical package body dimensions and solder pad geometry differ. PCB layout compatibility must be verified for specific applications.

Q: Does the M24C02-DRMF3TG/K automotive qualification affect its use in non-automotive applications?

A: No. AEC-Q100 qualification indicates enhanced reliability testing and is applicable to any application. The part functions identically in automotive and non-automotive environments.

Q: What is the impact of the reduced operating temperature range in M24C02-FMC6TG and M24C02-RMC6TG?

A: These parts operate from -40°C to 85°C, compared to the 24LC025-E/MC range of -40°C to 125°C. Applications requiring operation above 85°C must use the 24LC025-E/MC or M24C02-DRMF3TG/K.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three M24C02 substitutes carry ROHS3 compliance certification identical to the 24LC025-E/MC.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Physical interchangeability depends on PCB footprint design. The 8-MLP package (M24C02-DRMF3TG/K) and 8-UFDFPN packages (M24C02-FMC6TG and M24C02-RMC6TG) have different solder pad geometries despite identical pin pitch. PCB design must accommodate the specific package type selected.
