Parameter Comparison

Engineering Selection Recommendations

24AA08-I/P (Microchip Technology) is the primary recommended substitute. This part maintains identical I2C clock frequency (400 kHz) and access time (900 ns) specifications as the original AT24C08-10PC. The 24AA08-I/P is currently in active production status, ensuring long-term availability and supply chain stability. It provides extended supply voltage range (1.7V ~ 5.5V) and expanded operating temperature range (-40°C ~ 85°C), offering greater design flexibility. The part is ROHS3 compliant and verified as programmable through DiGi-Electronics, supporting modern manufacturing and environmental compliance requirements.

BR24G08-3 (Rohm Semiconductor) serves as an alternative substitute with identical 8Kbit capacity and 1K x 8 memory organization. This part operates at 1 MHz clock frequency, providing higher performance than the original specification. The BR24G08-3 supports extended voltage range (1.6V ~ 5.5V) and temperature range (-40°C ~ 85°C). However, this part is classified as obsolete, limiting its suitability for new designs requiring long-term component availability.

For applications requiring active production support and regulatory compliance, the 24AA08-I/P is the preferred selection. The BR24G08-3 may be considered only when existing inventory is available and long-term supply is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the 24AA08-I/P directly replace the AT24C08-10PC in existing designs?

A: Yes. Both parts share identical I2C interface protocol, 400 kHz clock frequency, 900 ns access time, and 8-DIP package configuration. The 24AA08-I/P is pin-compatible and functionally equivalent for applications operating within the original 4.5V ~ 5.5V supply voltage range.

Q: What is the difference in memory organization between AT24C08-10PC (1K x 8) and 24AA08-I/P (256 x 8 x 4)?

A: Both configurations provide 8Kbit total capacity. The 24AA08-I/P uses internal page organization (256 x 8 x 4) for page-write operations, while the AT24C08-10PC uses linear organization (1K x 8). This difference does not affect I2C protocol compatibility or functional substitution.

Q: Does the BR24G08-3 operate at the same speed as the original part?

A: No. The BR24G08-3 operates at 1 MHz clock frequency, which is 2.5 times faster than the AT24C08-10PC (400 kHz). This higher performance is backward compatible with designs expecting 400 kHz operation, as the I2C protocol supports variable clock speeds.

Q: Are there supply voltage compatibility concerns when substituting these parts?

A: The 24AA08-I/P and BR24G08-3 both support the original 4.5V ~ 5.5V range and extend compatibility to lower voltages (1.7V and 1.6V respectively). No voltage compatibility issues exist for direct substitution in the original operating range.

Q: What is the significance of the product status difference between these parts?

A: The AT24C08-10PC and BR24G08-3 are both classified as obsolete, indicating discontinued production. The 24AA08-I/P maintains active production status, ensuring availability for new designs and ongoing production requirements.

Q: Are all substitute parts RoHS compliant?

A: The AT24C08-10PC is RoHS non-compliant. Both substitute parts (24AA08-I/P and BR24G08-3) are ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.
