BR24C01-WMN6TP EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The BR24C01-WMN6TP is a 1Kbit I2C EEPROM memory IC manufactured by Rohm Semiconductor in 8-SOIC surface mount packaging. This part operates at 400 kHz clock frequency with a supply voltage range of 2.5V to 5.5V and is rated for -40°C to 85°C operating temperature. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Memory capacity (1Kbit) and organization (128 x 8)
I2C interface protocol
Clock frequency (400 kHz minimum)
Supply voltage compatibility (minimum 2.5V support)
Operating temperature range (-40°C to 85°C)
8-SOIC package footprint compatibility
RoHS3 compliance

Substitute parts are grouped into two categories: manufacturer-recommended alternatives with enhanced specifications, and similar parts with compatible electrical and mechanical characteristics. Parts with higher clock frequencies (1 MHz) or wider voltage ranges (1.6V minimum) remain functionally compatible as they exceed the minimum requirements of the BR24C01-WMN6TP.

Engineering Selection Recommendations

For direct replacement of the obsolete BR24C01-WMN6TP, select from active product status alternatives that maintain identical electrical specifications. BR24G01FJ-3GTE2 and BR24T01FJ-WE2 from Rohm Semiconductor provide pin-compatible substitutes with matching 400 kHz clock frequency and 5ms write cycle time. BR24T01FJ-WE2 offers the highest inventory availability at 17,900 pieces.

Microchip Technology 24AA01-I/SN and 24AA014-I/SN series provide cross-manufacturer alternatives with compatible I2C interface, 1Kbit capacity, and 400 kHz operation. These parts feature slightly lower minimum supply voltage (1.7V) and are available in higher quantities.

BR24G01FJ-3AGTE2 operates at 1 MHz clock frequency with extended voltage range (1.6V minimum), providing enhanced performance margin for applications requiring faster I2C communication.

All recommended substitutes maintain RoHS3 compliance, MSL Level 1 rating, and identical 8-SOIC package footprint. Selection should prioritize active product status and inventory availability for production continuity.

Frequently Asked Questions (FAQ)

Q: Can BR24G01FJ-3AGTE2 replace BR24C01-WMN6TP directly?

A: Yes. BR24G01FJ-3AGTE2 is electrically compatible with identical 1Kbit capacity, I2C interface, and 8-SOIC package. The 1 MHz clock frequency exceeds the 400 kHz requirement, and the 1.6V minimum supply voltage is compatible with 2.5V to 5.5V system designs.

Q: What is the difference between BR24C21FJ-E2 and BR24C01-WMN6TP?

A: BR24C21FJ-E2 has a 10ms write cycle time compared to 5ms for BR24C01-WMN6TP. This slower write performance may impact applications with strict timing requirements. All other electrical parameters remain compatible.

Q: Are Microchip 24AA01 and 24AA014 series interchangeable?

A: Yes, within the same packaging type. Both series provide 1Kbit I2C EEPROM with 400 kHz operation and 8-SOIC footprint. The 24AA014 variants feature faster access time (900 ns) compared to 24AA01 (3500 ns), but both meet the BR24C01-WMN6TP functional requirements.

Q: Does packaging type (Tube vs. Tape & Reel) affect electrical compatibility?

A: No. Packaging type affects only handling, storage, and assembly processes. Electrical and mechanical specifications remain identical between Tube and Tape & Reel variants of the same part number.

Q: Which substitute offers the best inventory availability?

A: BR24T01FJ-WE2 provides the highest stock level at 17,900 pieces, followed by 24AA01-I/SN at 9,861 pieces. Both are active products with RoHS3 compliance and identical core specifications to BR24C01-WMN6TP.
