Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC024H-E/P are qualified based on the following criteria:

Core Compatibility Requirements:

• Memory capacity: 2Kbit (256 x 8 organization)
• Interface protocol: I2C serial communication
• Package: 8-DIP through-hole form factor
• Voltage supply range: Must encompass or be compatible with 2.5V ~ 5.5V
• Write cycle time: 5ms (standard for this memory class)

Identified Substitutes:

1. 24LC02B-E/P – Direct Microchip equivalent with identical memory specifications and package. Clock frequency reduced to 400 kHz with corresponding access time increase to 900 ns. Maintains full voltage and temperature compatibility.

2. AT24C02C-PUM – Microchip AT series equivalent with matching 1 MHz clock frequency and 2Kbit capacity. Extended voltage range (1.7V ~ 5.5V) provides broader supply compatibility. Operating temperature limited to -40°C ~ 85°C, narrower than main part. Access time 550 ns.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can 24LC02B-E/P replace 24LC024H-E/P in all applications? A: 24LC02B-E/P is pin-compatible and functionally equivalent for I2C EEPROM applications. The reduced clock frequency (400 kHz vs. 1 MHz) and increased access time (900 ns vs. 400 ns) are acceptable in applications not requiring maximum speed performance. Both parts maintain identical voltage and temperature operating ranges.

Q: What is the key difference between AT24C02C-PUM and 24LC024H-E/P? A: AT24C02C-PUM matches the 1 MHz clock frequency and 400 ns access time class of the main part. The primary difference is the reduced maximum operating temperature (85°C vs. 125°C) and extended minimum supply voltage (1.7V vs. 2.5V). Select AT24C02C-PUM for low-voltage applications; select 24LC024H-E/P for extended temperature range requirements.

Q: Are all three parts pin-compatible in 8-DIP package? A: Yes. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole package with matching pinout for I2C EEPROM interface. Direct PCB footprint compatibility is confirmed.

Q: Which substitute offers the best availability? A: AT24C02C-PUM has the highest inventory level at 50,100 units in stock, compared to 1,503 units for 24LC02B-E/P and 975 units for the main part 24LC024H-E/P.

Q: Do all parts meet industrial compliance requirements? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting standard industrial and consumer electronics regulatory requirements.
