24VL025T/MNY EEPROM Equivalent & Substitute Parts

Part Overview

The 24VL025T/MNY is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, designed for non-volatile data storage applications requiring low-power operation and compact form factor. This device operates at 400 kHz I2C clock frequency with 900 ns access time, packaged in an 8-TDFN (2x3) surface mount configuration. The part is currently in active production status with 3,688 units in stock. Substitute parts become necessary when primary component availability is limited, when alternative voltage supply ranges are required for specific application requirements, or when different packaging formats are preferred for manufacturing processes.

Substitute Part Grouping Explanation

Substitution eligibility for the 24VL025T/MNY is determined by the following core parameters: 2Kbit memory capacity, 256 x 8 organization, I2C interface protocol, 400 kHz clock frequency, 5 ms write cycle time, surface mount technology, and ROHS3 compliance. All qualified substitute parts maintain these electrical and functional specifications. Variations in voltage supply range (1.5V ~ 3.6V for the main part versus 1.7V ~ 5.5V or 1.8V ~ 5.5V for substitutes) are acceptable when the application voltage requirements fall within the overlapping range of 1.7V ~ 3.6V. Package format differences (8-TDFN, 8-UDFN, 8-UFDFN) are mechanically compatible within the 8-pin DFN family with exposed pad configurations. Operating temperature range extensions (from -20°C ~ 85°C to -40°C ~ 85°C) represent enhanced capability and do not restrict substitution.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 24VL025T/MNY. Selection between substitutes should be based on application-specific voltage supply requirements and package format constraints. For applications operating within the 1.5V ~ 3.6V range, the 24VL025T/MNY remains the primary choice. When extended voltage operation (up to 5.5V) is required, BR24L02NUX-WTR, CAT34C02HU4IGT4A, CAT34C02VP2IGT4A, M24C02-FMC6TG, or M24C02-RMC6TG are functionally equivalent. CAT34C02VP2IGT4A and 24VL025T/MNY share identical 8-WFDFN package geometry, minimizing PCB layout modifications. The onsemi CAT34C02 series (both variants) and STMicroelectronics M24C02 series employ 8-UFDFN packaging, which is mechanically compatible but requires footprint verification. Rohm BR24L02NUX-WTR offers the highest inventory availability at 184,920 units. All substitutes maintain 900 ns access time and 5 ms write cycle specifications, ensuring timing compatibility in I2C bus applications.

Frequently Asked Questions (FAQ)

Q: Can I use BR24L02NUX-WTR as a direct replacement for 24VL025T/MNY?

A: BR24L02NUX-WTR is functionally equivalent in memory capacity, organization, I2C protocol, clock frequency, and write cycle time. The primary differences are extended voltage range (1.8V ~ 5.5V versus 1.5V ~ 3.6V), extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 85°C), and package format (8-UFDFN versus 8-WFDFN). If your application operates within 1.8V ~ 3.6V and uses standard PCB assembly processes, substitution is valid. Package footprint differences require verification against your PCB design.

Q: What is the difference between 8-WFDFN and 8-UFDFN packages?

A: Both are 8-pin DFN (Dual Flat No-Lead) packages with exposed pads, measuring 2x3 mm. The primary distinction is in pin pitch and pad dimensions. 8-WFDFN and 8-UFDFN are mechanically similar but have different land pattern requirements. Verify your PCB footprint specifications before substituting between these package types.

Q: Are all substitute parts I2C protocol compatible with the 24VL025T/MNY?

A: Yes. All listed substitutes operate at 400 kHz I2C clock frequency with identical memory organization (256 x 8) and interface protocol. They are I2C bus compatible and require no firmware or software modifications.

Q: Which substitute offers the best availability?

A: BR24L02NUX-WTR from Rohm Semiconductor has the highest inventory at 184,920 units. CAT34C02VP2IGT4A from onsemi is the second option with 34,490 units available.

Q: Can I use M24C02-RMC6TG in applications requiring 1.5V operation?

A: No. M24C02-RMC6TG has a minimum voltage specification of 1.8V. For applications requiring 1.5V operation, the 24VL025T/MNY is the only option among these parts, as it supports 1.5V ~ 3.6V.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL rating of 1 (Unlimited), matching the regulatory and environmental specifications of the 24VL025T/MNY.
