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

Part Overview

The 24C00-I/P is a 128-bit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for I2C serial communication applications. This non-volatile memory device operates at 400 kHz clock frequency with a 4.6 µs access time and is housed in an 8-DIP through-hole package. The device is actively produced and ROHS3 compliant, making it suitable for industrial and commercial applications requiring persistent data storage. Substitute parts are identified when equivalent electrical specifications, memory organization, interface protocol, and physical packaging are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

The 24LC00-I/P qualifies as a direct substitute for the 24C00-I/P based on the following critical parameters:

• Memory Capacity & Organization: Both devices provide 128-bit storage with 16 x 8 organization
• Interface Protocol: Both implement I2C serial communication at 400 kHz
• Access & Write Performance: Identical access time (4.6 µs) and write cycle time (4 ms)
• Physical Package: Both use 8-DIP through-hole packaging with 0.300" (7.62mm) spacing
• Operating Temperature: Both rated for -40°C ~ 85°C operation
• Compliance & Status: Both are ROHS3 compliant, REACH unaffected, and actively produced

The primary difference is the supply voltage range, where the 24LC00-I/P supports a wider operating window (2.5V ~ 5.5V) compared to the 24C00-I/P (4.5V ~ 5.5V). This extended lower voltage capability makes the 24LC00-I/P suitable for all applications where the 24C00-I/P is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 24C00-I/P and 24LC00-I/P are actively produced devices with identical ROHS3 compliance and REACH unaffected status. The 24LC00-I/P provides superior supply voltage flexibility with its 2.5V lower operating threshold, enabling deployment in low-power and battery-operated applications where the 24C00-I/P cannot function. For applications constrained to 4.5V ~ 5.5V operation, both devices are functionally equivalent. Selection should be based on system power supply architecture and available inventory. Both devices carry MSL-1 moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

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

A: Yes. The 24LC00-I/P is electrically and mechanically compatible with the 24C00-I/P across all specified parameters. The extended voltage range of the 24LC00-I/P (2.5V ~ 5.5V) encompasses the 24C00-I/P operating window (4.5V ~ 5.5V), ensuring functional equivalence in all applications where the original part operates.

Q: Are there package or pinout differences between these devices?

A: No. Both devices use identical 8-DIP through-hole packaging with 0.300" (7.62mm) spacing. Pinout and mechanical dimensions are equivalent, allowing direct socket substitution without PCB modification.

Q: What is the significance of the voltage range difference?

A: The 24LC00-I/P supports operation down to 2.5V, while the 24C00-I/P requires minimum 4.5V. This makes the 24LC00-I/P suitable for low-voltage applications, battery-powered systems, and designs with variable supply rails. For fixed 5V systems, both devices perform identically.

Q: Do these devices have different I2C communication protocols?

A: No. Both devices implement identical I2C serial communication at 400 kHz clock frequency with matching 4.6 µs access time and 4 ms write cycle time. No firmware or software modifications are required when substituting between these parts.

Q: Are there compliance or certification differences?

A: No. Both devices are ROHS3 compliant, REACH unaffected, and carry identical MSL-1 moisture sensitivity ratings. Regulatory and environmental compliance is equivalent across both parts.
