Parameter Comparison

Engineering Selection Recommendations

Both the 24AA08H-I/P and 24AA08-I/P are active products from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on availability and inventory requirements. The 24AA08-I/P offers higher inventory availability at 2408 units compared to 819 units for the 24AA08H-I/P. Both devices meet ROHS3 compliance and REACH requirements, making either suitable for applications requiring regulatory compliance. The 24AA08-I/P is verified as programmable through DiGi-Electronics, while the 24AA08H-I/P status is not verified; this distinction may be relevant for programming and testing workflows.

Frequently Asked Questions (FAQ)

Q: Can the 24AA08-I/P directly replace the 24AA08H-I/P in existing designs?

A: Yes. Both parts share identical electrical parameters (8Kbit capacity, I2C interface, 400 kHz operation, 1.7V–5.5V supply range, -40°C to 85°C operating temperature) and physical packaging (8-DIP through-hole). No circuit modifications are required.

Q: Are there differences in memory organization or access characteristics?

A: No. Both devices feature 256 x 8 x 4 memory organization, 900 ns access time, and 5 ms write cycle time. Functional behavior is identical.

Q: What is the significance of the different part number suffixes?

A: The suffix variation (H vs. standard) does not reflect differences in the core electrical or mechanical specifications provided. Both parts are manufactured by Microchip Technology and meet identical compliance standards.

Q: Do both parts require the same PCB footprint and pin configuration?

A: Yes. Both use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pin assignments. PCB layouts and footprints are interchangeable.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN and HTSUS classifications.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain requirements. The 24AA08-I/P offers higher stock levels. Both are active products suitable for production use.
