AT24C64D-MAPD-T Equivalent & Substitute Parts

Part Overview

The AT24C64D-MAPD-T is a 64Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface communication at 400 kHz with 900 ns access time. This component is classified as Active product status and meets AEC-Q100 automotive qualification standards. The device operates across a supply voltage range of 2.5V to 5.5V and temperature range of -40°C to 125°C, packaged in 8-UDFN (2x3) surface mount configuration with exposed pad.

Substitute parts are identified when equivalent memory capacity, interface protocol, and package form factor are maintained while accommodating variations in electrical performance characteristics and operating conditions.

Substitute Part Grouping Explanation

Substitute parts for the AT24C64D-MAPD-T are qualified based on the following criteria:

• Memory capacity: 64Kbit maintained
• Memory organization: 8K x 8 maintained
• Interface protocol: I2C maintained
• Package type: 8-UFDFN Exposed Pad maintained
• Mounting method: Surface Mount maintained
• Compliance: ROHS3 Compliant maintained

The substitute parts identified are STMicroelectronics M24C64 series devices, which satisfy all core functional and physical requirements. Variations in clock frequency, access time, voltage supply range, and operating temperature are within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both M24C64-DFMC6TG and M24C64-FMC6TG are functionally equivalent substitutes for the AT24C64D-MAPD-T. Selection between these options is determined by packaging and inventory requirements:

M24C64-DFMC6TG is supplied in Tape & Reel (TR) packaging format with 14,000 units in stock inventory.

M24C64-FMC6TG is supplied in Cut Tape (CT) & Digi-Reel® packaging format with 65,300 units in stock inventory.

Both substitute parts maintain ROHS3 compliance and active product status. The STMicroelectronics M24C64 series devices offer enhanced performance characteristics including higher clock frequency (1 MHz versus 400 kHz) and faster access time (450 ns versus 900 ns), with extended voltage supply range (1.7V minimum versus 2.5V minimum). Operating temperature range for substitute parts is -40°C to 85°C, which is narrower than the main part specification of -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can M24C64-DFMC6TG and M24C64-FMC6TG be used interchangeably with AT24C64D-MAPD-T?

A: Yes. Both substitute parts maintain identical memory capacity (64Kbit), memory organization (8K x 8), I2C interface protocol, and 8-UFDFN package configuration. Functional compatibility is established through these core parameters.

Q: What is the difference between M24C64-DFMC6TG and M24C64-FMC6TG?

A: The primary difference is packaging format. M24C64-DFMC6TG is supplied in Tape & Reel format, while M24C64-FMC6TG is supplied in Cut Tape & Digi-Reel format. Both devices are electrically identical.

Q: Are there operating temperature limitations when substituting?

A: The substitute parts operate within -40°C to 85°C range, compared to the main part's -40°C to 125°C range. Applications requiring operation above 85°C must retain the AT24C64D-MAPD-T.

Q: Do the substitute parts require different supply voltage handling?

A: The substitute parts accept lower minimum supply voltage (1.7V versus 2.5V) and maintain the same maximum (5.5V). This provides broader voltage compatibility in most applications.

Q: Are moisture sensitivity levels a consideration for substitution?

A: The substitute parts feature MSL 1 (Unlimited) compared to the main part's MSL 3 (168 Hours). This represents improved moisture resistance characteristics in the substitute devices.
