Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC014-I/MC is determined by the following critical parameters:

• Memory Capacity & Organization: All substitutes must provide 1Kbit capacity in 128 x 8 organization to maintain firmware and hardware compatibility
• Interface Protocol: I2C interface is mandatory; no alternative protocols are acceptable
• Supply Voltage Compatibility: Substitute parts must operate within overlapping voltage ranges with the main part or support the application's supply voltage
• Package & Mounting: Surface mount packages with compatible pinout and footprint (8-pin DFN/UDFN variants) are acceptable
• Temperature Range: Operating temperature range must cover the application's thermal requirements
• Compliance & Status: Active product status and ROHS3 compliance are required for production use

Three qualified substitutes meet these criteria: 24LC01BT-I/MC (Microchip Technology), AT24C01D-MAHM-T (Microchip Technology), and BR24G01NUX-3TTR (Rohm Semiconductor).

Parameter Comparison

Engineering Selection Recommendations

24LC01BT-I/MC is the primary substitute for the 24LC014-I/MC. Both devices are manufactured by Microchip Technology with identical memory specifications, I2C interface, clock frequency, write cycle time, and voltage supply range. The 24LC01BT-I/MC features improved access time (4.6 µs vs. 900 ns) and is available in higher inventory quantities. Both devices maintain ROHS3 compliance and Active product status. The 24LC01BT-I/MC is packaged in Tape & Reel format, suitable for high-volume production environments.

AT24C01D-MAHM-T is a secondary substitute offering higher I2C clock frequency (1 MHz vs. 400 kHz) and faster access time (4.5 µs). This device operates at a reduced voltage supply range (1.7V ~ 3.6V), which may limit compatibility in applications requiring the full 2.5V ~ 5.5V range of the main part. The AT24C01D-MAHM-T is suitable for low-power applications and maintains ROHS3 compliance and Active status.

BR24G01NUX-3TTR is a third-party substitute manufactured by Rohm Semiconductor. This device matches the 400 kHz clock frequency and 5ms write cycle time of the main part. The BR24G01NUX-3TTR offers the widest voltage supply range (1.6V ~ 5.5V), providing maximum compatibility across diverse application requirements. The device is ROHS3 compliant and Active status. Access time is not specified in the provided data.

All three substitutes maintain identical memory capacity, organization, I2C interface, operating temperature range, and surface mount packaging compatibility. Selection should be based on specific application requirements for voltage range, clock frequency, and access time performance.

Frequently Asked Questions (FAQ)

Q: Can the 24LC01BT-I/MC directly replace the 24LC014-I/MC in existing designs?

A: Yes. Both devices share identical memory capacity (1Kbit), organization (128 x 8), I2C interface, clock frequency (400 kHz), write cycle time (5ms), voltage supply range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (8-VFDFN). The 24LC01BT-I/MC is a direct functional equivalent.

Q: What is the key difference between the AT24C01D-MAHM-T and the main part?

A: The AT24C01D-MAHM-T operates at 1 MHz I2C clock frequency (vs. 400 kHz) and supports a reduced voltage supply range of 1.7V ~ 3.6V. Applications requiring the full 2.5V ~ 5.5V range must verify compatibility before substitution. All other parameters remain equivalent.

Q: Is the BR24G01NUX-3TTR from a different manufacturer compatible?

A: Yes. The BR24G01NUX-3TTR from Rohm Semiconductor meets all critical substitution criteria: 1Kbit capacity, 128 x 8 organization, I2C interface, 400 kHz clock frequency, 5ms write cycle time, and -40°C ~ 85°C operating temperature. The device offers the widest voltage supply range (1.6V ~ 5.5V) among all substitutes.

Q: Are there package compatibility concerns between DFN and UDFN variants?

A: The 24LC014-I/MC uses 8-VFDFN packaging, while AT24C01D-MAHM-T and BR24G01NUX-3TTR use 8-UFDFN packaging. Both are 8-pin surface mount packages with 2x3mm footprints. PCB layout verification is required to confirm mechanical and electrical compatibility before design implementation.

Q: Which substitute offers the best performance for high-speed I2C applications?

A: The AT24C01D-MAHM-T supports 1 MHz I2C clock frequency, providing higher data transfer rates compared to the 400 kHz operation of the main part and other substitutes. However, voltage supply range compatibility must be verified for the specific application.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three substitute parts (24LC01BT-I/MC, AT24C01D-MAHM-T, and BR24G01NUX-3TTR) are ROHS3 compliant and maintain Active product status, meeting current regulatory and supply chain requirements.
