24LC00T/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC00T/SN is a 128-bit EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates via I2C interface at 400 kHz clock frequency and is housed in an 8-SOIC surface mount package. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging requirements necessitate alternative configurations.

Substitute Part Grouping Explanation

Substitute parts for the 24LC00T/SN are qualified based on identical electrical and mechanical parameters. All substitute candidates maintain the same memory capacity (128 bit), memory organization (16 x 8), I2C interface protocol, clock frequency (400 kHz), access time (4.6 µs), write cycle time (4 ms), supply voltage range (2.5V ~ 5.5V), and physical package specification (8-SOIC). Substitution eligibility is determined by these core parameters, which ensure functional and pin-level compatibility within the target application circuit.

The primary distinction between the main part and substitutes is packaging format: the 24LC00T/SN is supplied in Tape & Reel (TR) format, while alternatives are available in Tube and Cut Tape (CT) & Digi-Reel® formats. Operating temperature range may vary between part numbers and must be evaluated against application requirements.

Engineering Selection Recommendations

All three part numbers are manufactured by Microchip Technology and maintain active production status. Each part carries ROHS3 compliance certification and unlimited moisture sensitivity rating (MSL 1), confirming suitability for standard manufacturing and storage environments.

The 24LC00T/SN and 24LC00/SN are specified for 0°C ~ 70°C operating temperature range, suitable for commercial and light industrial applications. The 24LC00T-I/SN extends the operating temperature range to -40°C ~ 85°C, qualifying it for industrial and extended-temperature applications.

Selection between these parts should be based on packaging requirements and temperature specifications. Tape & Reel format (24LC00T/SN) is optimized for high-volume automated assembly. Tube packaging (24LC00/SN) supports lower-volume or manual assembly processes. Cut Tape & Digi-Reel® format (24LC00T-I/SN) provides flexibility for both manual and automated handling with extended temperature performance.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. The 24LC00T/SN, 24LC00/SN, and 24LC00T-I/SN share identical electrical specifications including memory capacity, I2C interface, clock frequency, access time, write cycle time, and supply voltage range. They are pin-compatible and functionally equivalent in circuit operation.

Q: What is the difference between these part numbers? A: The primary differences are packaging format and operating temperature range. The 24LC00T/SN uses Tape & Reel packaging for automated assembly. The 24LC00/SN uses Tube packaging for manual or lower-volume assembly. The 24LC00T-I/SN uses Cut Tape & Digi-Reel® packaging and supports extended temperature operation from -40°C to 85°C, compared to 0°C to 70°C for the other variants.

Q: Can I use 24LC00T-I/SN in place of 24LC00T/SN? A: Yes, from an electrical and mechanical standpoint. The 24LC00T-I/SN is functionally compatible and offers extended temperature range capability. Verify that your application does not require the specific Tape & Reel packaging format of the 24LC00T/SN.

Q: Which part should I select for industrial temperature applications? A: The 24LC00T-I/SN is specified for -40°C ~ 85°C operating temperature and is the appropriate choice for industrial and extended-temperature environments.

Q: Are all parts RoHS compliant? A: Yes. All three part numbers carry ROHS3 compliance certification and are suitable for applications requiring RoHS compliance.
