Engineering Selection Recommendations
All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the BR24C01-RMN6TP. The primary distinction among substitutes is clock frequency capability and minimum supply voltage specification.
ROHM Semiconductor Substitutes (Same Manufacturer Family): BR24G01FJ-3AGTE2, BR24G01FJ-3GTE2, and BR24T01FJ-WE2 are active production alternatives from ROHM Semiconductor. These parts share identical 8-SOIC packaging and operating temperature range. BR24G01FJ-3GTE2 and BR24T01FJ-WE2 operate at 400 kHz, directly supporting legacy 100 kHz I2C bus configurations. BR24G01FJ-3AGTE2 operates at 1 MHz for higher-speed applications. All three offer reduced write cycle time (5 ms vs. 10 ms) and lower minimum supply voltage (1.6V vs. 1.8V).
Microchip Technology Substitutes (Cross-Manufacturer): Microchip 24-series parts (24AA014H-I/SN, 24AA014-I/SN, 24AA014HT-I/SN, 24AA014T-I/SN, 24AA01-I/SN, 24AA01H-I/SN) are active production devices with 400 kHz I2C operation. These parts are available in both tube and tape & reel packaging options. Most variants specify 1.7V minimum supply voltage. The 24LC01BH-E/SN variant extends operating temperature to 125°C but requires 2.5V minimum supply voltage, limiting compatibility in low-voltage applications.
Frequently Asked Questions (FAQ)
Q: Can BR24G01FJ-3AGTE2 (1 MHz) replace BR24C01-RMN6TP (100 kHz) in existing designs?
A: Yes. The BR24G01FJ-3AGTE2 operates at 1 MHz, which is backward compatible with 100 kHz I2C bus speeds. The device automatically adapts to the bus clock frequency. Identical 8-SOIC packaging and pinout ensure direct physical replacement.
Q: What is the difference between BR24G01FJ-3GTE2 and BR24T01FJ-WE2?
A: Both operate at 400 kHz with identical electrical specifications and 8-SOIC packaging. The primary difference is inventory availability (705 Pcs vs. 17,900 Pcs) and base product series designation (BR24G01 vs. BR24T01). Functionally, they are equivalent for I2C EEPROM applications.
Q: Are Microchip 24AA014 and 24AA01 series interchangeable?
A: Yes, within the same clock frequency and packaging specification. Both 24AA014 and 24AA01 variants operate at 400 kHz with 1Kbit capacity and 8-SOIC packaging. Selection between them depends on packaging preference (tube vs. tape & reel) and specific temperature or voltage requirements.
Q: Does the 24LC01BH-E/SN require circuit modifications due to 2.5V minimum supply voltage?
A: The 24LC01BH-E/SN minimum supply voltage of 2.5V may restrict use in systems designed for 1.8V operation. If the application circuit operates above 2.5V, no modifications are required. For 1.8V systems, alternative parts with 1.6V or 1.7V minimum specifications (BR24G01FJ-3GTE2, 24AA014-I/SN, 24AA01-I/SN) are more suitable.
Q: What is the significance of packaging designations (TR, Tube, 8-SOP vs. 8-SOIC)?
A: TR (Tape & Reel) and Tube refer to supply packaging formats for manufacturing and assembly. 8-SOP and 8-SOIC both describe the physical component package (8-pin Small Outline IC, 0.154" width, 3.90mm). All identified substitutes use identical physical packaging, ensuring PCB footprint compatibility regardless of supply format.
Q: Can I use 24AA014HT-I/SN (Tape & Reel) instead of BR24C01-RMN6TP (Tape & Reel)?
A: Yes. Both are supplied in tape & reel format with identical 8-SOIC physical packaging. The 24AA014HT-I/SN operates at 400 kHz with 5 ms write cycle time, providing equivalent or improved performance compared to the 100 kHz, 10 ms specification of BR24C01-RMN6TP.
