BR24C01-DS6TP EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The BR24C01-DS6TP is a 1Kbit I2C EEPROM memory IC manufactured by Rohm Semiconductor in 8-TSSOP packaging. This component operates at 400 kHz I2C clock frequency with a 5ms write cycle time and supports supply voltages from 4.5V to 5.5V across an operating temperature range of -40°C to 85°C. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution eligibility for the BR24C01-DS6TP is determined by the following critical parameters:

Memory Capacity & Organization: Must be 1Kbit with 128 x 8 organization
Interface Protocol: Must support I2C communication at 400 kHz
Write Cycle Time: Must not exceed 5ms
Supply Voltage Range: Must encompass or be compatible with 4.5V ~ 5.5V operation
Operating Temperature: Must support -40°C ~ 85°C range
Package Type: 8-TSSOP or 8-MSOP packages are mechanically compatible
Compliance: Must maintain ROHS3 compliance and equivalent moisture sensitivity

Substitute parts are grouped into two categories: manufacturer-recommended active alternatives and similar functionally equivalent parts from alternative manufacturers. Parts with extended voltage ranges (1.6V ~ 5.5V or 1.7V ~ 5.5V) remain compatible as they encompass the original 4.5V ~ 5.5V specification.

Engineering Selection Recommendations

Primary Recommendation: BR24G01FJ-3GTE2 (Rohm Semiconductor, Active Status)

This part is the manufacturer-recommended substitute from Rohm Semiconductor with active product status. It maintains identical memory specifications, I2C interface, and 400 kHz clock frequency. The extended supply voltage range (1.6V ~ 5.5V) provides broader operational flexibility while remaining fully compatible with the original 4.5V ~ 5.5V requirement. Package transition from 8-TSSOP to 8-SOP-J requires PCB layout adjustment but maintains equivalent electrical performance.

Secondary Recommendation: 24AA01-I/MS or 24AA01H-I/MS (Microchip Technology, Active Status)

Microchip Technology alternatives provide active product status with identical 1Kbit capacity and I2C 400 kHz interface. These parts support extended supply voltage (1.7V ~ 5.5V) and maintain ROHS3 compliance. The 8-MSOP package is mechanically compatible with the original 8-TSSOP footprint. Access time specifications vary (3500 ns for 24AA01-I/MS, 900 ns for 24AA01H-I/MS) but do not affect substitution eligibility as write cycle time remains at 5ms.

Alternative Consideration: BR24G01FVJ-3GTE2 (Rohm Semiconductor, Not For New Designs)

This part matches the original 8-TSSOP package exactly and maintains all electrical specifications. However, its "Not For New Designs" status makes it unsuitable for new production applications despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use 24AA014-I/MS as a direct replacement for BR24C01-DS6TP?

A: Yes. Both parts share identical 1Kbit capacity, 128 x 8 organization, I2C 400 kHz interface, and 5ms write cycle time. The 24AA014-I/MS supply voltage range (1.7V ~ 5.5V) encompasses the original specification (4.5V ~ 5.5V). Package transition from 8-TSSOP to 8-MSOP requires PCB layout modification but maintains electrical compatibility.

Q: What is the difference between 24AA01-I/MS and 24AA014-I/MS?

A: Both parts are functionally equivalent 1Kbit I2C EEPROMs with identical memory organization and interface specifications. The primary difference is access time: 24AA01-I/MS specifies 3500 ns access time, while 24AA014-I/MS specifies 900 ns. This difference does not affect substitution eligibility as both meet the 5ms write cycle requirement.

Q: Why does BR24G01FVJ-3GTE2 show "Not For New Designs" status?

A: This designation indicates the part is in end-of-life phase and should not be selected for new product development. Although technically compatible with BR24C01-DS6TP, active alternatives such as BR24G01FJ-3GTE2 or Microchip 24AA01 series are preferred for new designs.

Q: Are there package compatibility concerns between 8-TSSOP and 8-MSOP?

A: Both packages are 8-pin surface mount configurations with 0.118" (3.00mm) width. While pin pitch and lead geometry differ slightly, both are compatible with standard 8-pin SOIC footprints. PCB layout verification is required when transitioning between these packages.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original BR24C01-DS6TP specification. Moisture sensitivity levels are equivalent (MSL 1 or MSL 2), with MSL 1 parts offering unlimited shelf life.

Q: What is the significance of extended voltage ranges (1.6V or 1.7V minimum)?

A: Extended lower voltage limits provide operational flexibility in low-power applications. Since the original part specifies 4.5V minimum, substitute parts with 1.6V or 1.7V minimums remain fully compatible and can operate across the entire original voltage range while supporting additional lower-voltage applications.
