AT24C16-10PI EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The AT24C16-10PI is a 16Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 900 ns access time. This component is classified as obsolete, which necessitates identification of functionally equivalent active alternatives for new designs and production continuity. The part operates within a 4.5V to 5.5V supply voltage range and is housed in an 8-DIP through-hole package suitable for legacy circuit board designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C16-10PI is determined by strict equivalence across the following critical parameters: memory capacity (16Kbit), memory organization (2K x 8), interface protocol (I2C), clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), package configuration (8-DIP through-hole), and pin compatibility. The identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign. Voltage supply range and operating temperature range variations are noted as secondary parameters that may extend application flexibility beyond the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both 24AA16H-I/P and 24AA16-E/P are active production parts manufactured by Microchip Technology and maintain full electrical and mechanical compatibility with the AT24C16-10PI. The 24AA16-E/P offers extended operating temperature range to 125°C and is available in higher inventory quantities (12,200 units), making it the primary recommendation for new designs and production applications. Both substitute parts feature ROHS3 compliance and reduced minimum supply voltage (1.7V), providing enhanced environmental and regulatory alignment compared to the obsolete AT24C16-10PI. The 24AA16H-I/P serves as an alternative with equivalent specifications and active product status.

Frequently Asked Questions (FAQ)

Q: Can the 24AA16-E/P directly replace the AT24C16-10PI without circuit modification?

A: Yes. Both parts share identical memory capacity (16Kbit), organization (2K x 8), I2C interface, clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), and 8-DIP package configuration. Pin-to-pin compatibility is maintained.

Q: What is the significance of the extended temperature range in the 24AA16-E/P?

A: The 24AA16-E/P operates from -40°C to 125°C, compared to the AT24C16-10PI's -40°C to 85°C range. This extended specification accommodates applications requiring higher temperature operation without component substitution.

Q: Are there voltage supply differences between the substitute parts and the original?

A: The AT24C16-10PI requires 4.5V to 5.5V supply voltage. Both substitute parts (24AA16H-I/P and 24AA16-E/P) accept 1.7V to 5.5V, providing broader voltage compatibility and enabling operation in lower-voltage system designs.

Q: What is the packaging difference between the substitute parts?

A: Both 24AA16H-I/P and 24AA16-E/P are supplied in tube packaging, while the original AT24C16-10PI packaging is not specified. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole package configuration for circuit board mounting.

Q: Why is the AT24C16-10PI classified as obsolete?

A: The AT24C16-10PI is no longer in active production. The 24AA16H-I/P and 24AA16-E/P represent the current active alternatives from Microchip Technology for this memory capacity and interface specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 24AA16H-I/P and 24AA16-E/P are ROHS3 compliant, whereas the AT24C16-10PI is RoHS non-compliant. This compliance status is relevant for applications subject to environmental and regulatory requirements.
