Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C08-10PI-1.8 is determined by the following critical parameters:

• Memory capacity: 8Kbit minimum
• Interface protocol: I2C
• Package form factor: 8-DIP (0.300", 7.62mm)
• Operating temperature range: -40°C to 85°C
• Supply voltage compatibility: overlap with 1.8V ~ 5.5V range

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

24LC08B-I/P is the primary substitute option. This part is manufactured by Microchip Technology with active product status and ROHS3 compliance. The supply voltage range of 2.5V ~ 5.5V is compatible with designs operating above 2.5V. Inventory availability is 3400 units. This part is verified as programmable by DiGi-Electronics.

BR24G08-3 is an alternative substitute manufactured by Rohm Semiconductor. This part offers a higher clock frequency of 1 MHz and a lower minimum supply voltage of 1.6V, providing broader voltage compatibility. However, the product status is obsolete. ROHS3 compliance is confirmed. Inventory availability is 1629 units.

For new designs requiring long-term component availability and regulatory compliance, 24LC08B-I/P is the recommended selection. For applications requiring extended low-voltage operation below 2.5V, BR24G08-3 provides the necessary voltage range, subject to availability constraints.

Frequently Asked Questions (FAQ)

Q: Can 24LC08B-I/P directly replace AT24C08-10PI-1.8 in existing designs?

A: Yes, for applications operating at supply voltages of 2.5V and above. Both parts share identical 8-DIP package dimensions, I2C interface protocol, 8Kbit capacity, 400 kHz clock frequency, and -40°C to 85°C operating temperature range. The 24LC08B-I/P has a minimum supply voltage of 2.5V, whereas the original part operates from 1.8V. Verify your circuit's minimum supply voltage before substitution.

Q: What is the difference between 24LC08B-I/P and BR24G08-3?

A: Both are 8Kbit I2C EEPROM devices in 8-DIP packages. The 24LC08B-I/P operates at 400 kHz with 2.5V ~ 5.5V supply range. The BR24G08-3 operates at 1 MHz with 1.6V ~ 5.5V supply range. The higher clock frequency of BR24G08-3 enables faster data transfer rates. The lower minimum voltage of BR24G08-3 supports applications requiring operation below 2.5V.

Q: Are there any compliance differences between these parts?

A: The original AT24C08-10PI-1.8 is RoHS non-compliant. Both substitute parts, 24LC08B-I/P and BR24G08-3, are ROHS3 compliant. For applications subject to RoHS regulations, either substitute part satisfies compliance requirements.

Q: What is the memory organization difference between 24LC08B-I/P and the other parts?

A: The 24LC08B-I/P has memory organization of 256 x 8 x 4, while AT24C08-10PI-1.8 and BR24G08-3 both have 1K x 8 organization. Both configurations provide 8Kbit total capacity and are functionally equivalent for I2C interface applications.

Q: Can BR24G08-3 be used in applications requiring 1.8V minimum supply voltage?

A: No. BR24G08-3 has a minimum supply voltage of 1.6V, which does not meet the 1.8V requirement. For applications requiring 1.8V operation, neither substitute part is suitable. The original AT24C08-10PI-1.8 or equivalent parts with 1.8V minimum specification are required.
