24AA014HT-I/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24AA014HT-I/MS is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 8-MSOP surface mount packaging. This component is classified as Active product status and is RoHS3 compliant. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where substitute devices meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24AA014HT-I/MS are qualified based on the following critical parameters:

• Memory capacity: 1Kbit with 128 x 8 organization
• Interface protocol: I2C communication standard
• Supply voltage compatibility: Minimum 1.7V operation required
• Operating temperature range: -40°C to 85°C
• Surface mount packaging: 8-pin MSOP or 8-pin TSSOP configurations
• Compliance certifications: RoHS3 and REACH requirements

Two substitute parts meet these criteria with variations in clock frequency and package designation.

Parameter Comparison

Engineering Selection Recommendations

BR24G01FVM-3AGTTR is the preferred substitute for new designs. This part maintains Active product status, identical memory specifications, and 8-MSOP package compatibility with the main part. The elevated clock frequency of 1 MHz provides backward compatibility with 400 kHz I2C bus operation while offering enhanced performance capability. Supply voltage range and operating temperature specifications are equivalent.

BR24G01FVJ-3GTE2 is a secondary substitute option with identical electrical specifications at 400 kHz clock frequency. However, this part carries "Not For New Designs" product status and uses 8-TSSOP packaging, requiring PCB layout modification. This option is suitable only for legacy system maintenance or replacement scenarios where existing board designs accommodate TSSOP footprints.

Frequently Asked Questions (FAQ)

Q: Can BR24G01FVM-3AGTTR operate at 400 kHz like the original 24AA014HT-I/MS?

A: Yes. The BR24G01FVM-3AGTTR supports I2C clock frequencies up to 1 MHz, which includes full backward compatibility with 400 kHz bus operation. The device will function correctly on any I2C bus operating at or below its maximum frequency rating.

Q: What is the difference between 8-MSOP and 8-TSSOP packaging?

A: Both are 8-pin surface mount packages with different physical dimensions. 8-MSOP measures 0.118" width (3.00mm), while 8-TSSOP measures 0.118" width (3.00mm). Package footprints differ and require different PCB land patterns. Direct physical substitution on existing PCBs is not possible without layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both BR24G01FVJ-3GTE2 and BR24G01FVM-3AGTTR are RoHS3 compliant with MSL rating 1 (Unlimited), matching the compliance profile of the 24AA014HT-I/MS.

Q: What does "Not For New Designs" mean for BR24G01FVJ-3GTE2?

A: This designation indicates the manufacturer does not recommend this part for new product development. It may be subject to future discontinuation or limited supply. BR24G01FVJ-3GTE2 is suitable for replacement or maintenance of existing systems only.

Q: Is the supply voltage range difference significant between 1.7V and 1.6V minimum?

A: Both substitute parts operate at 1.6V minimum, which is 0.1V lower than the main part's 1.7V specification. This provides equivalent or superior low-voltage performance. Applications requiring operation below 1.7V will benefit from substitute selection.
