Engineering Selection Recommendations

Primary Recommendation: BR24G01FJ-3AGTE2 is the manufacturer-recommended substitute. This part maintains all core memory specifications while offering enhanced performance through 1 MHz clock frequency and extended voltage range (1.6V ~ 5.5V). Active product status ensures long-term availability and supply chain stability.

Alternative Selections: BR24G01FJ-3GTE2 and BR24T01FJ-WE2 provide direct functional equivalence with identical 400 kHz clock frequency and 5ms write cycle time, matching the original part's performance profile. Both are active Rohm Semiconductor products with ROHS3 compliance.

Cross-Manufacturer Options: Microchip Technology 24AA01 and 24AA014 series parts (24AA01-I/SN, 24AA014-I/SN, 24AA014H-I/SN, 24AA014HT-I/SN, 24AA014T-I/SN, 24AA01H-I/SN) provide functional equivalence with identical memory organization, I2C interface, and 400 kHz operation. These parts feature slightly lower minimum supply voltage (1.7V vs 4.5V) and are actively produced with ROHS3 compliance.

All recommended substitutes maintain 8-SOIC package compatibility, -40°C to 85°C operating temperature range, and ROHS3 compliance status.

Frequently Asked Questions (FAQ)
