24AA04-I/MC EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24AA04-I/MC is a 4Kbit I2C EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 400 kHz I2C bus speed with 900 ns access time, designed for applications requiring persistent data storage in embedded systems. The device is currently in active production status with 2600 units available in tube packaging. Substitute parts are identified when identical electrical specifications, memory organization, interface protocol, and physical packaging are maintained across alternative part numbers or packaging formats from the same manufacturer.

Substitute Part Grouping Explanation

The 24AA04T-I/MC qualifies as a direct substitute for the 24AA04-I/MC based on the following criteria:

Identical Electrical Parameters:

• Memory capacity: 4Kbit
• Memory organization: 256 x 8 x 2
• Interface protocol: I2C at 400 kHz
• Access time: 900 ns
• Write cycle time: 5 ms
• Supply voltage range: 1.7V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

Identical Physical Parameters:

• Package type: 8-VFDFN Exposed Pad
• Supplier device package: 8-DFN (2x3)
• Mounting type: Surface Mount

Manufacturer Consistency:

• Both parts manufactured by Microchip Technology
• Both parts share the same base product number: 24AA04

The substitution is based solely on packaging format differentiation. The 24AA04-I/MC is supplied in tube packaging, while the 24AA04T-I/MC is supplied in cut tape (CT) and Digi-Reel® format. This distinction affects inventory management and automated assembly processes but does not alter functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 24AA04-I/MC and 24AA04T-I/MC are active production devices from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

24AA04-I/MC (Tube Packaging): Select this part number when procurement processes require tube packaging format or when inventory management systems are configured for tube-based component handling.

24AA04T-I/MC (Cut Tape & Digi-Reel® Packaging): Select this part number when automated assembly equipment requires tape-and-reel format or when high-volume production processes utilize pick-and-place machinery. This part number offers significantly higher inventory availability (5,000,400 units versus 2,600 units).

Compliance Consideration: The 24AA04-I/MC carries RoHS3 compliance certification, while the 24AA04T-I/MC is marked as RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the 24AA04-I/MC variant.

Frequently Asked Questions (FAQ)

Q: Are the 24AA04-I/MC and 24AA04T-I/MC electrically identical?

A: Yes. Both parts have identical memory capacity (4Kbit), interface protocol (I2C 400 kHz), access time (900 ns), supply voltage range (1.7V ~ 5.5V), and operating temperature range (-40°C ~ 85°C). The only differences are packaging format and RoHS compliance status.

Q: What is the difference between tube and cut tape packaging?

A: Tube packaging is used for manual assembly and lower-volume production. Cut tape and Digi-Reel® packaging is designed for automated pick-and-place assembly equipment. Both formats contain the same die and provide identical electrical performance.

Q: Can I use 24AA04T-I/MC in place of 24AA04-I/MC in my design?

A: Functionally yes, provided your application does not have RoHS compliance requirements. The 24AA04-I/MC is RoHS3 compliant while the 24AA04T-I/MC is not. If RoHS compliance is mandatory, use only the 24AA04-I/MC.

Q: Why is there an inventory difference between these part numbers?

A: The 24AA04T-I/MC in cut tape format has higher inventory availability (5,000,400 units) compared to the 24AA04-I/MC in tube format (2,600 units). This reflects typical distribution patterns where tape-and-reel packaging is produced in larger quantities for high-volume manufacturing.

Q: Are the physical packages identical?

A: Yes. Both parts use the 8-VFDFN Exposed Pad package with 8-DFN (2x3) dimensions. The physical footprint and pin configuration are identical, allowing direct substitution at the PCB level.
