24AA128T-I/MF EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24AA128T-I/MF is a 128Kbit I2C EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 400 kHz I2C bus frequency with 900 ns access time and supports a supply voltage range of 1.7V to 5.5V. The component is housed in an 8-VDFN Exposed Pad surface mount package (8-DFN-S 6x5) and is classified as Active product status. Equivalent and substitute parts are identified based on matching electrical specifications, memory organization, interface protocol, and physical packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24AA128T-I/MF is determined by strict equivalence across the following critical parameters: memory capacity (128Kbit), memory organization (16K x 8 bit configuration), I2C serial interface protocol, clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), supply voltage range (1.7V to 5.5V), operating temperature range (-40°C to 85°C), and physical package specification (8-VDFN Exposed Pad surface mount). The substitute part 24AA128-I/MF matches all electrical and mechanical parameters. The only difference between the main part and substitute is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tube format. Both parts share the same base product number 24AA128 and are manufactured by Microchip Technology with identical Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The 24AA128-I/MF serves as a direct functional equivalent to the 24AA128T-I/MF. Both parts are manufactured by Microchip Technology with Active product status and identical electrical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance. The 24AA128T-I/MF in Tape & Reel format is suitable for high-volume automated assembly operations. The 24AA128-I/MF in Tube format is appropriate for lower-volume applications, manual assembly, or situations where Tape & Reel packaging is unavailable. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory conformance for industrial and consumer applications. Moisture sensitivity level 1 (Unlimited) indicates no special storage or handling precautions are required for either part.

Frequently Asked Questions (FAQ)

Q: Can the 24AA128-I/MF replace the 24AA128T-I/MF in production?

A: Yes. The 24AA128-I/MF is electrically and mechanically equivalent. The only difference is packaging format (Tube versus Tape & Reel). Substitution is valid for any application where the component's electrical and physical specifications are met.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Tube packaging supplies components in plastic tubes, typically used for manual assembly or lower-volume production. Both formats contain identical components with the same electrical performance.

Q: Are there any compatibility concerns when switching between these parts?

A: No compatibility concerns exist. Both parts use the same 8-VDFN Exposed Pad surface mount package, I2C interface protocol, and electrical specifications. PCB footprints, firmware, and system integration remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 24AA128T-I/MF and 24AA128-I/MF are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What determines whether a part can substitute for the 24AA128T-I/MF?

A: Substitution is valid when the alternative part matches all critical parameters: 128Kbit memory capacity, 16K x 8 organization, I2C interface, 400 kHz clock frequency, 900 ns access time, 5ms write cycle time, 1.7V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 8-VDFN Exposed Pad surface mount package.
