Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC01BHT-I/LT are qualified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Memory capacity: 1Kbit (128 x 8 organization)
• Interface protocol: I2C at 400 kHz
• Package type: SC-70-5 (5-TSSOP, SOT-353)
• Surface mount configuration
• Non-volatile EEPROM technology
• Write cycle time: 5ms
• Moisture sensitivity level: MSL 1

Allowable Parameter Variations:

• Voltage supply range: Substitutes may have extended lower voltage support (1.7V minimum) while maintaining 5.5V upper limit
• Access time: Substitutes may have longer access times (up to 4.6 µs) than the primary part (900 ns)
• Operating temperature: Substitutes may have extended upper temperature rating (up to 125°C) while maintaining -40°C lower limit
• Packaging format: Substitutes may differ in tape & reel (TR) versus cut tape (CT) & Digi-Reel® configurations

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by Microchip Technology and maintain active product status with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the primary part 24LC01BHT-I/LT.

24AA01HT-I/LT provides direct functional equivalence with identical access time (900 ns) and operating temperature range. This part extends the minimum supply voltage to 1.7V, enabling operation in lower-voltage applications while maintaining the same tape & reel packaging format.

24AA01T-I/LT offers the same voltage flexibility as 24AA01HT-I/LT with extended minimum supply voltage to 1.7V. Access time is increased to 3500 ns, which remains within acceptable I2C timing specifications. Packaging differs in cut tape & Digi-Reel® format rather than tape & reel.

24LC01BT-E/LT maintains the 2.5V minimum supply voltage of the primary part while extending the maximum operating temperature to 125°C. Access time increases to 4.6 µs. This part is suitable for applications requiring extended temperature operation within the 2.5V to 5.5V supply range.

24LC01BT-I/LT matches the primary part's voltage supply range (2.5V ~ 5.5V) and operating temperature (-40°C ~ 85°C) with increased access time of 4.6 µs. Packaging format differs in cut tape & Digi-Reel® configuration.

Frequently Asked Questions (FAQ)

Q: Can 24AA01HT-I/LT replace 24LC01BHT-I/LT in all applications?

A: Yes, 24AA01HT-I/LT is a direct functional equivalent. It maintains identical memory capacity (1Kbit), interface protocol (I2C 400 kHz), access time (900 ns), and operating temperature range (-40°C ~ 85°C). The extended minimum supply voltage (1.7V vs 2.5V) provides additional flexibility for low-voltage designs without affecting compatibility in standard 2.5V to 5.5V applications.

Q: What is the impact of increased access time in 24AA01T-I/LT and 24LC01BT variants?

A: Access time specifies the delay from address input to valid data output. The primary part 24LC01BHT-I/LT has 900 ns access time, while substitute parts 24AA01T-I/LT and 24LC01BT variants have 3500 ns or 4.6 µs access time. Both values comply with I2C 400 kHz timing requirements. Selection depends on application timing constraints; faster access time (900 ns) is preferred for time-critical operations, while longer access times are acceptable for standard I2C bus operations.

Q: How do packaging format differences affect part selection?

A: The primary part 24LC01BHT-I/LT is supplied in tape & reel (TR) format for high-volume automated assembly. Substitute parts 24AA01T-I/LT and 24LC01BT-I/LT are supplied in cut tape (CT) & Digi-Reel® format, suitable for lower-volume or mixed-component pick-and-place operations. Both formats contain identical die and electrical specifications; selection is based on procurement and assembly process requirements.

Q: Is 24LC01BT-E/LT suitable for high-temperature applications?

A: 24LC01BT-E/LT extends the maximum operating temperature to 125°C compared to 85°C for the primary part. This part is specified for applications requiring sustained operation at elevated temperatures while maintaining 2.5V to 5.5V supply voltage compatibility. Access time increases to 4.6 µs, which remains compliant with I2C 400 kHz specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (24AA01HT-I/LT, 24AA01T-I/LT, 24LC01BT-E/LT, and 24LC01BT-I/LT) are ROHS3 compliant with MSL 1 rating, matching the primary part 24LC01BHT-I/LT. All parts are manufactured by Microchip Technology and maintain active product status.
