24AA014T-I/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24AA014T-I/ST is a 1Kbit I2C EEPROM memory IC manufactured by Microchip Technology, packaged in 8-TSSOP surface mount configuration. This non-volatile memory device operates across a wide supply voltage range (1.7V to 5.5V) and temperature range (-40°C to 85°C), making it suitable for embedded systems, IoT devices, and industrial applications requiring persistent data storage. The part is currently Active and ROHS3 compliant. Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 1Kbit memory capacity, I2C interface, 128 x 8 memory organization, 8-TSSOP package, and compatible operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24AA014T-I/ST are qualified based on the following critical parameters that determine functional compatibility:

Core Electrical Parameters:

• Memory capacity: 1Kbit
• Memory format: EEPROM (non-volatile)
• Memory organization: 128 x 8
• Interface protocol: I2C
• Supply voltage range: Must encompass or be compatible with 1.7V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Write cycle time: 5ms

Mechanical Parameters:

• Package type: 8-TSSOP
• Package dimensions: 0.173" width, 4.40mm width
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

Substitutes may vary in clock frequency (400 kHz to 1 MHz) and access time (550 ns to 900 ns) while maintaining full functional compatibility. Voltage supply ranges may differ slightly (1.6V, 1.7V, 1.8V minimum thresholds) but must support the application's operating voltage. All qualified substitutes maintain identical memory organization, I2C protocol, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

AT24C01C-XHM-T and AT24CS01-XHM-T are direct Microchip Technology alternatives with identical voltage supply range (1.7V ~ 5.5V) and package specifications. Both operate at 1 MHz clock frequency with 550 ns access time, providing improved performance over the 24AA014T-I/ST. Both are Active products with ROHS3 compliance and unlimited moisture sensitivity rating.

M24C01-RDW6TP (STMicroelectronics) matches the 24AA014T-I/ST electrical performance (400 kHz, 900 ns access time) with identical package and compliance status. Minimum supply voltage is 1.8V, which is compatible with applications operating above this threshold.

Secondary Substitutes (Rohm Semiconductor, Package Variant):

BR24G01FVT-3GE2, BR24L01AFVT-WE2, and BR24T01FVT-WE2 are Rohm Semiconductor alternatives with 8-TSSOP-B package variant. All maintain 1Kbit capacity, 400 kHz I2C operation, and ROHS3 compliance. Minimum supply voltages range from 1.6V to 1.8V. The 8-TSSOP-B package variant is mechanically compatible with standard 8-TSSOP footprints in most applications.

Not Recommended for New Designs:

M24C01-WDW6TP carries "Not For New Designs" status and has a restricted minimum supply voltage of 2.5V. This part should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can AT24C01C-XHM-T replace 24AA014T-I/ST directly?

A: Yes. Both parts share identical 1Kbit capacity, I2C interface, 128 x 8 organization, 8-TSSOP package, and voltage supply range (1.7V ~ 5.5V). AT24C01C-XHM-T operates at higher clock frequency (1 MHz vs 400 kHz) and faster access time (550 ns vs 900 ns), making it a performance-enhanced substitute.

Q: What is the difference between 8-TSSOP and 8-TSSOP-B packages?

A: Both are 8-pin thin shrink small outline packages with 0.173" width and 4.40mm width dimensions. The -B variant indicates a package revision by the manufacturer. Both are mechanically compatible with standard 8-TSSOP PCB footprints.

Q: Are Rohm Semiconductor parts compatible with Microchip designs?

A: Yes. BR24G01FVT-3GE2, BR24L01AFVT-WE2, and BR24T01FVT-WE2 maintain identical I2C protocol, memory organization, package form factor, and operating temperature range. Verify minimum supply voltage requirements for your application (1.6V to 1.8V thresholds).

Q: Why do some substitutes have different clock frequencies?

A: AT24C01C-XHM-T and AT24CS01-XHM-T operate at 1 MHz I2C clock frequency compared to the 24AA014T-I/ST's 400 kHz. Higher clock frequency enables faster data transfer while maintaining full backward compatibility with 400 kHz I2C bus implementations.

Q: Is M24C01-WDW6TP suitable for new designs?

A: No. M24C01-WDW6TP is marked "Not For New Designs" and has a minimum supply voltage of 2.5V, restricting its use in low-voltage applications. Select M24C01-RDW6TP or alternative Active-status parts for new product development.

Q: What compliance certifications apply to all substitutes?

A: All qualified substitutes are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). All are classified under ECCN EAR99 and HTSUS 8542.32.0051.
