24FC512-I/MF EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24FC512-I/MF is a 512Kbit EEPROM memory IC manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial interface communication. This component operates at 1 MHz clock frequency with 400 ns access time, supporting supply voltages from 1.7V to 5.5V across industrial temperature ranges (-40°C to 85°C). The device is housed in an 8-DFN-S (6x5) surface mount package with exposed pad configuration. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, substitute parts may be required due to inventory constraints, application-specific performance requirements, or supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the 24FC512-I/MF is determined by strict equivalence across the following critical parameters:

• Memory capacity: 512Kbit (64K x 8 organization)
• Serial interface protocol: I2C
• Package configuration: 8-DFN-S (6x5) with exposed pad
• Supply voltage compatibility: 1.7V ~ 5.5V range
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3, REACH Unaffected, EAR99 classification

The 24AA512-I/MF qualifies as a direct substitute based on identical memory capacity, I2C interface, package type, voltage range, and temperature specifications. Performance differences in clock frequency and access time do not preclude substitution where application timing requirements permit operation at reduced speeds.

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC512-I/MF and 24AA512-I/MF are active products with identical compliance certifications (ROHS3, REACH Unaffected, EAR99). Selection between these parts is determined by application timing requirements. The 24FC512-I/MF operates at 1 MHz with 400 ns access time, suitable for applications requiring maximum I2C bus speed and minimal data access latency. The 24AA512-I/MF operates at 400 kHz with 900 ns access time, appropriate for applications with relaxed timing constraints or systems operating at lower I2C bus frequencies. Both devices share identical memory capacity, organization, package footprint, voltage range, and temperature specifications, ensuring direct PCB compatibility and functional interchangeability within timing-compatible applications.

Frequently Asked Questions (FAQ)

Q: Can the 24AA512-I/MF replace the 24FC512-I/MF in all applications?

A: Substitution is valid only when application I2C bus timing permits operation at 400 kHz clock frequency and 900 ns access time. Applications requiring 1 MHz operation or 400 ns access time specifications must use the 24FC512-I/MF.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-DFN-S (6x5) surface mount package with exposed pad configuration, ensuring identical PCB footprint and mounting requirements.

Q: Do these parts have different supply voltage requirements?

A: No. Both parts operate across the identical 1.7V to 5.5V supply voltage range and support the same -40°C to 85°C operating temperature specification.

Q: What compliance certifications apply to both parts?

A: Both the 24FC512-I/MF and 24AA512-I/MF are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL rating of 1 (unlimited moisture sensitivity).

Q: Is the I2C interface protocol identical between these parts?

A: Yes. Both parts implement the I2C serial interface protocol with identical memory organization (64K x 8) and 512Kbit total capacity, ensuring software compatibility.
