24C01C-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24C01C-E/SN is a 1Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial communication. This device operates at 100 kHz clock frequency with a 4.5V to 5.5V supply voltage range and is housed in an 8-SOIC surface mount package. The part is currently in active production status with verified programmability and full RoHS3 compliance. Substitute parts are identified when equivalent memory capacity, interface protocol, package form factor, and operating temperature range are maintained while allowing variations in clock frequency and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C01C-E/SN is determined by the following critical parameters:

• Memory capacity must remain 1Kbit with 128 x 8 organization
• I2C serial interface protocol is mandatory
• 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width) is required
• Operating temperature range must encompass -40°C to 125°C
• Access time specification of 4.6 µs must be maintained or improved

Variations permitted in substitute parts include clock frequency (provided the I2C interface remains compatible) and supply voltage range (provided minimum voltage supports 4.5V operation). All substitute parts must maintain non-volatile EEPROM technology and identical memory organization.

Parameter Comparison

Engineering Selection Recommendations

The 24LC01B-E/SN qualifies as a direct substitute for the 24C01C-E/SN based on matching memory capacity, interface protocol, package form factor, and operating temperature specifications. Both parts are manufactured by Microchip Technology and maintain active production status with full RoHS3 compliance and REACH unaffected designation.

The 24LC01B-E/SN provides enhanced clock frequency capability (400 kHz versus 100 kHz) and extended supply voltage range (2.5V to 5.5V versus 4.5V to 5.5V), making it suitable for applications requiring higher I2C bus speeds or lower voltage operation. The identical access time and memory organization ensure functional compatibility in existing circuit designs.

Both parts carry Moisture Sensitivity Level 1 (Unlimited) and identical ECCN and HTSUS classifications, confirming regulatory and compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 24LC01B-E/SN replace the 24C01C-E/SN in existing designs?

A: Yes. Both parts share identical memory capacity (1Kbit), memory organization (128 x 8), I2C interface, access time (4.6 µs), operating temperature range (-40°C to 125°C), and 8-SOIC package dimensions. The 24LC01B-E/SN operates at higher clock frequency (400 kHz) and supports lower supply voltages (2.5V minimum), making it functionally compatible.

Q: What is the primary difference between these parts?

A: The 24LC01B-E/SN supports I2C clock frequencies up to 400 kHz compared to 100 kHz for the 24C01C-E/SN, and operates across a wider supply voltage range (2.5V to 5.5V versus 4.5V to 5.5V). Memory capacity and interface protocol remain identical.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width, ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.32.0051) classifications.

Q: Can I use the 24LC01B-E/SN in a 4.5V to 5.5V supply application?

A: Yes. The 24LC01B-E/SN supply voltage range (2.5V to 5.5V) encompasses the 4.5V to 5.5V operating window, ensuring full compatibility.
