Key Parameters

Substitute Part Grouping Explanation

Substitution for the AT24C02-10PI-2.7 is determined by strict equivalence in the following parameters:

• Memory capacity: 2Kbit
• Memory format: EEPROM
• Interface protocol: I2C
• Clock frequency: 400 kHz
• Memory organization: 256 x 8
• Package type: 8-DIP (0.300", 7.62mm)
• Mounting method: Through Hole
• Access time: 900 ns
• Write cycle time: 5ms

All substitute parts listed maintain these core specifications. Variations in supply voltage range and operating temperature range are noted but do not prevent functional substitution when application requirements are met.

Parameter Comparison

Engineering Selection Recommendations

24AA024H-I/P is a direct functional equivalent with extended supply voltage range (1.7V ~ 5.5V) and active product status. This part offers the broadest voltage compatibility and maintains the full operating temperature range of the original part (-40°C ~ 85°C). ROHS3 compliance provides regulatory advantage for new designs.

24LC02B-I/P is the manufacturer-recommended substitute with active product status and ROHS3 compliance. Supply voltage range (2.5V ~ 5.5V) is compatible with the original part's 2.7V minimum specification. Full operating temperature range (-40°C ~ 85°C) is maintained. DiGi-Electronics programmable verification status confirms functional compatibility.

24LC02B/P is a manufacturer-recommended alternative with active product status and ROHS3 compliance. This part operates within a narrower temperature range (0°C ~ 70°C) compared to the original specification. Selection of this part requires confirmation that application operating temperature requirements fall within 0°C ~ 70°C limits. Supply voltage range (2.5V ~ 5.5V) is compatible with the original part's 2.7V minimum specification.

Frequently Asked Questions (FAQ)

Q: Can 24AA024H-I/P directly replace AT24C02-10PI-2.7 in existing designs?

A: Yes. The 24AA024H-I/P maintains all core functional parameters: 2Kbit capacity, I2C interface, 400 kHz clock frequency, 256 x 8 organization, 8-DIP package, 900 ns access time, and 5ms write cycle time. The extended supply voltage range (1.7V ~ 5.5V) provides broader compatibility than the original part.

Q: What is the difference between 24LC02B-I/P and 24LC02B/P?

A: Both parts are functionally equivalent with identical memory specifications and I2C interface. The primary difference is operating temperature range: 24LC02B-I/P operates from -40°C ~ 85°C, while 24LC02B/P operates from 0°C ~ 70°C. Selection depends on application temperature requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (24AA024H-I/P, 24LC02B-I/P, and 24LC02B/P) are ROHS3 compliant, whereas the original AT24C02-10PI-2.7 is RoHS non-compliant. This provides regulatory compliance advantage for new production.

Q: What supply voltage range is safe for all substitute parts?

A: The common voltage range across all substitutes is 2.5V ~ 5.5V. The original part specified 2.7V ~ 5.5V. When selecting a substitute, confirm that application supply voltage meets the minimum requirement of the chosen part.

Q: Is the 8-DIP package identical across all parts?

A: Yes. All parts use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout and mechanical dimensions, enabling direct PCB footprint compatibility.

Q: Which substitute part has the highest inventory availability?

A: 24LC02B/P has the highest inventory at 15,100 pieces. 24LC02B-I/P has 5,310 pieces, and 24AA024H-I/P has 1,784 pieces.
