24C00-I/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24C00-I/ST 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-TSSOP surface mount package. The part is currently in active production status with 1075 units available in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range. The 24LC00-I/ST serves as a direct manufacturer-recommended alternative, offering expanded voltage supply range while maintaining identical functional specifications and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C00-I/ST is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (128 bit, 16 x 8 configuration)
• Interface protocol and clock frequency (I2C, 400 kHz)
• Access and write cycle timing specifications (4.6 µs, 4 ms)
• Physical package dimensions and mounting technology (8-TSSOP surface mount)
• Operating temperature range (-40°C ~ 85°C)
• Regulatory compliance status (ROHS3, REACH Unaffected)

The 24LC00-I/ST qualifies as a direct substitute based on identical performance across all functional and mechanical parameters. The primary distinction is an expanded voltage supply range (2.5V ~ 5.5V versus 4.5V ~ 5.5V), which provides broader operational flexibility while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 24C00-I/ST and 24LC00-I/ST maintain active production status and full ROHS3 compliance. The 24LC00-I/ST is the manufacturer-recommended substitute, offering identical functional performance with extended voltage supply compatibility. Selection between these parts should be based on circuit voltage requirements: the 24C00-I/ST is suitable for 4.5V ~ 5.5V applications, while the 24LC00-I/ST accommodates broader supply ranges from 2.5V ~ 5.5V. Both parts carry unlimited moisture sensitivity classification and are suitable for standard PCB assembly processes without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 24LC00-I/ST replace the 24C00-I/ST in existing designs?

A: Yes. The 24LC00-I/ST is electrically and mechanically equivalent across all functional parameters. The expanded voltage range of the substitute part ensures compatibility with the original part's operating range and beyond.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical 8-TSSOP packaging with 0.173" width and 4.40mm dimensions. Pinout and PCB footprint are identical.

Q: What is the primary advantage of using the 24LC00-I/ST?

A: The 24LC00-I/ST supports a lower minimum supply voltage (2.5V versus 4.5V), enabling use in low-voltage applications while maintaining full compatibility with standard 5V systems.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 24C00-I/ST and 24LC00-I/ST are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity classification (MSL 1).

Q: Are there differences in memory performance or timing?

A: No. Access time (4.6 µs), write cycle time (4 ms), and I2C clock frequency (400 kHz) are identical across both parts.
