Engineering Selection Recommendations

24AA16/P is a direct functional equivalent with active product status and ROHS3 compliance. This part operates within the original AT24C16-10PC temperature range (0°C to 70°C) and provides extended supply voltage compatibility (1.7V to 5.5V). Inventory availability is 846 units.

24AA16-E/P is the manufacturer-recommended substitute with the widest operating temperature range (-40°C to 125°C) and highest inventory availability (12,200 units). This part is suitable for applications requiring extended temperature operation beyond the original specification. ROHS3 compliance is confirmed.

24AA16-I/P is a manufacturer-recommended substitute with active product status and ROHS3 compliance, offering an operating temperature range of -40°C to 85°C. This part provides a balance between extended temperature capability and inventory availability (2,100 units).

All substitute parts maintain identical memory capacity, organization, I2C interface frequency, access time, and write cycle time specifications. Selection should be based on application temperature requirements and supply voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can 24AA16/P directly replace AT24C16-10PC in existing designs?

A: Yes. The 24AA16/P maintains identical memory specifications (16Kbit, 2K x 8 organization), I2C interface (400 kHz), timing parameters (900 ns access time, 5ms write cycle), and 8-DIP package. The part operates within the original temperature range (0°C to 70°C) and is electrically compatible for applications within this envelope.

Q: What is the difference between 24AA16-E/P and 24AA16-I/P?

A: Both parts are manufacturer-recommended substitutes with identical memory and interface specifications. The primary difference is operating temperature range: 24AA16-E/P operates from -40°C to 125°C, while 24AA16-I/P operates from -40°C to 85°C. Select based on application temperature requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (24AA16/P, 24AA16-E/P, 24AA16-I/P) are ROHS3 compliant, whereas the original AT24C16-10PC is RoHS non-compliant.

Q: Does the extended voltage range of substitute parts affect compatibility?

A: No. The substitute parts operate at 1.7V to 5.5V supply voltage, which encompasses the original part's 4.5V to 5.5V range. Applications designed for the original voltage range will function identically with substitute parts.

Q: Are there any package or pinout differences?

A: No. All parts use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout and mechanical dimensions.
