Equivalent & Substitute Parts for 24C00/P EEPROM Memory IC

Part Overview

The 24C00/P is a 128-bit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for I2C serial communication applications. This through-hole 8-DIP package device operates at 400 kHz clock frequency with 4.6 µs access time, suitable for embedded systems requiring non-volatile data storage. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent substitute parts are identified to provide design flexibility, inventory alternatives, and extended operating range options for system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24C00/P are qualified based on the following critical parameters that determine functional equivalence:

• Memory capacity (128 bit) and organization (16 x 8)
• I2C serial interface protocol at 400 kHz operation
• Access time (4.6 µs) and write cycle time (4 ms)
• 8-DIP through-hole package configuration
• ROHS3 compliance and MSL-1 rating

The identified substitutes maintain identical memory specifications, interface characteristics, and physical packaging. Variations in supply voltage range and operating temperature range are permitted within the substitute group, as these represent extended or modified specifications rather than functional incompatibilities.

Engineering Selection Recommendations

All three parts—24C00/P, 24LC00-I/P, and 24LC00/P—are active production components from Microchip Technology with ROHS3 compliance and verified programmability status. Selection between these parts should be based on system-level requirements:

The 24C00/P operates within a 4.5V to 5.5V supply range and 0°C to 70°C temperature window, making it suitable for standard industrial and consumer applications with regulated power supplies and controlled thermal environments.

The 24LC00-I/P extends the operating envelope to -40°C to 85°C and accepts supply voltages from 2.5V to 5.5V, providing compatibility with extended temperature applications and lower-voltage system designs.

The 24LC00/P maintains the 0°C to 70°C temperature specification while accepting the wider 2.5V to 5.5V supply range, offering intermediate flexibility for low-voltage applications within standard temperature ranges.

All parts share identical memory capacity, interface protocol, access characteristics, and physical packaging, ensuring direct functional interchangeability within their respective operating parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can 24LC00-I/P replace 24C00/P in all applications?

A: The 24LC00-I/P is functionally equivalent with extended operating specifications. It accepts lower supply voltages (2.5V minimum versus 4.5V) and operates across a wider temperature range (-40°C to 85°C versus 0°C to 70°C). Direct substitution is valid for applications operating within the 24C00/P's original parameter boundaries.

Q: What is the difference between 24LC00-I/P and 24LC00/P?

A: Both parts accept 2.5V to 5.5V supply voltage. The primary difference is operating temperature range: 24LC00-I/P operates from -40°C to 85°C, while 24LC00/P operates from 0°C to 70°C. Select based on your application's thermal requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and electrical interface specifications.

Q: Do these parts require different PCB layouts?

A: No. The identical 8-DIP package and I2C interface specifications ensure that no PCB layout modifications are required when substituting between these parts.

Q: Are there compliance differences between the three parts?

A: All three parts maintain ROHS3 compliance, MSL-1 rating, and REACH unaffected status. No compliance-related restrictions apply to substitution.

Q: Which part should I select for a new design?

A: Selection depends on your system's power supply and operating temperature requirements. For standard 5V systems with 0°C to 70°C operation, any part is suitable. For systems requiring extended temperature range or lower supply voltages, select 24LC00-I/P or 24LC00/P accordingly.
