Engineering Selection Recommendations

Primary Recommendation: BR24G01FVT-3GE2 is the manufacturer-recommended substitute with active product status, ensuring long-term availability and supply chain continuity. This part maintains identical functional specifications while offering improved supply voltage floor (1.6V vs 2.5V). Tape & Reel packaging supports high-volume production requirements.

Secondary Alternatives: Microchip Technology 24AA series parts (24AA01-I/MS, 24AA014-I/MS, 24AA014H-I/MS, 24AA014HT-I/MS, 24AA014T-I/MS, 24AA01H-I/MS, 24AA01HT-I/MS, 24AA01T-I/MS) provide active product status with full functional compatibility. These components are ROHS3 compliant and support the required operating temperature range. MSL ratings of 1 (except 24AA01-I/MS with MSL 2) meet standard moisture sensitivity requirements.

Avoid: BR24G01FVJ-3GTE2 carries "Not For New Designs" status and should not be selected for new product development despite functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can BR24C01-WDS6TP be directly replaced with BR24G01FVT-3GE2? A: Yes. Both parts share identical memory capacity (1Kbit), organization (128 x 8), I2C interface, 400 kHz clock frequency, and 5ms write cycle time. The substitute offers expanded supply voltage range and active product status. Package designation differs (8-TSSOP vs 8-TSSOP-B), but both are 8-pin TSSOP variants with compatible pinouts for standard applications.

Q: What is the difference between 8-TSSOP and 8-MSOP packaging? A: Both are 8-pin surface mount packages with identical pin configurations for I2C EEPROM applications. 8-TSSOP features 0.173" width (4.40mm), while 8-MSOP features 0.118" width (3.00mm). Selection depends on PCB layout constraints and available board space. Electrical and functional performance are equivalent.

Q: Are Microchip 24AA series parts compatible with Rohm BR24 series? A: Yes. All listed Microchip parts maintain identical memory specifications, I2C interface, clock frequency, and operating temperature range. Pin configuration and functional behavior are compatible. Supply voltage ranges differ slightly (1.7V minimum for Microchip vs 1.6V for Rohm BR24G01), but both support standard 3.3V and 5V system voltages.

Q: What does MSL rating 1 vs MSL rating 2 mean for component selection? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life under controlled storage conditions. MSL 2 requires baking before reflow if storage exceeds one year. For production environments with standard component handling, MSL 1 parts (most substitutes) are preferred. 24AA01-I/MS carries MSL 2 and requires moisture management protocols.

Q: Can I use 24AA01T-I/MS or 24AA014T-I/MS in place of BR24C01-WDS6TP? A: Yes. Both parts meet all functional requirements with active product status and Tape & Reel packaging suitable for automated assembly. Access time differs (3500 ns for 24AA01T-I/MS, 900 ns for 24AA014T-I/MS) but does not affect I2C protocol compatibility or application performance at 400 kHz operation.

Q: Why is BR24G01FVJ-3GTE2 listed but not recommended? A: BR24G01FVJ-3GTE2 carries "Not For New Designs" status, indicating Rohm Semiconductor has discontinued active support. While functionally compatible, this part should not be selected for new product development. BR24G01FVT-3GE2 is the active replacement from the same manufacturer.
