24LC01BHT-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC01BHT-E/SN is a 1Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for I2C serial communication applications operating at 400 kHz. This non-volatile memory device is packaged in an 8-SOIC surface mount configuration and is currently in active production status. Substitute parts are identified when equivalent electrical specifications, memory capacity, interface protocol, and physical packaging are maintained across alternative manufacturers or packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC01BHT-E/SN are qualified based on the following critical parameters that must remain constant:

• Memory capacity: 1Kbit (128 x 8 organization)
• Interface protocol: I2C serial communication
• Clock frequency: 400 kHz operation
• Package type: 8-SOIC surface mount
• Physical dimensions: 0.154" width, 3.90mm
• Write cycle time: 5ms
• Supply voltage compatibility: minimum 2.5V operation
• RoHS3 compliance status

Substitutes are identified from alternative manufacturers (STMicroelectronics) or alternative packaging formats (Cut Tape & Digi-Reel versus Tape & Reel) when all electrical and mechanical parameters align with the primary device specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance certification. The 24LC01BT-E/SN is a direct Microchip Technology substitute with identical electrical specifications and operating temperature range, differentiated only by packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and access time specification (4.6 µs versus 900 ns). The M24C01-RMN6TP from STMicroelectronics provides functional equivalence with identical memory capacity, interface, and write cycle time, with the following considerations: supply voltage range extends to 1.8V minimum (versus 2.5V for Microchip devices), and maximum operating temperature is limited to 85°C (versus 125°C for the primary part). Selection between these substitutes depends on application requirements for minimum supply voltage, maximum operating temperature, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the 24LC01BT-E/SN replace the 24LC01BHT-E/SN in all applications?

A: Yes, the 24LC01BT-E/SN is electrically equivalent with identical memory capacity, I2C interface, clock frequency, write cycle time, and operating temperature range. The difference is packaging format: 24LC01BT-E/SN is supplied in Cut Tape & Digi-Reel format, while 24LC01BHT-E/SN is supplied in Tape & Reel format. Access time specification differs (4.6 µs versus 900 ns), but both meet the 400 kHz I2C protocol requirements.

Q: What are the limitations of the M24C01-RMN6TP substitute?

A: The M24C01-RMN6TP from STMicroelectronics maintains 1Kbit memory capacity, I2C interface, and 400 kHz operation. Two parameter differences exist: minimum supply voltage is 1.8V (lower than the 2.5V minimum of Microchip devices), and maximum operating temperature is 85°C (lower than the 125°C maximum of the primary part). Applications requiring operation above 85°C or with supply voltages below 2.5V must use the Microchip alternatives.

Q: Are all three parts pin-compatible?

A: Yes, all three parts use the 8-SOIC package with identical 0.154" width and 3.90mm dimensions, ensuring mechanical and electrical pin compatibility for surface mount PCB applications.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes, the 24LC01BT-E/SN, M24C01-RMN6TP, and primary 24LC01BHT-E/SN are all ROHS3 compliant.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on reels for automated assembly lines. Cut Tape & Digi-Reel format supplies components on cut tape segments or alternative reel formats. Both formats contain identical components; packaging format selection depends on assembly equipment compatibility and order quantity requirements.
