Substitute Part Grouping Explanation

Substitute parts for the AT24C16-10PC-2.7 are qualified based on the following critical parameters:

  • Memory capacity: 16Kbit with 2K x 8 organization
  • Interface protocol: I2C at 400 kHz
  • Electrical performance: 900 ns access time, 5ms write cycle time
  • Package compatibility: 8-DIP through-hole form factor
  • Voltage supply compatibility: minimum 2.7V operation capability

Two active substitute parts meet these criteria: 24AA16/P (direct manufacturer equivalent) and 24AA16-E/P (manufacturer-recommended alternative). Both parts maintain identical memory specifications, interface characteristics, and package configuration as the obsolete AT24C16-10PC-2.7.

Engineering Selection Recommendations

Both 24AA16/P and 24AA16-E/P are active products with ROHS3 compliance, addressing the obsolescence of AT24C16-10PC-2.7. Selection between these substitutes depends on application requirements:

24AA16/P is suitable for applications requiring standard industrial temperature range (0°C ~ 70°C) with lower supply voltage capability (1.7V minimum). This part is verified as programmable through DiGi-Electronics.

24AA16-E/P extends operating temperature range to -40°C ~ 125°C, accommodating extended temperature applications. This manufacturer-recommended part provides broader environmental specifications while maintaining identical core memory and interface functionality. Higher inventory availability (12,200 pcs) supports production continuity.

Both parts maintain backward compatibility with AT24C16-10PC-2.7 designs through identical I2C protocol implementation, memory organization, and 8-DIP package configuration.

Frequently Asked Questions (FAQ)

Q: Can 24AA16/P and 24AA16-E/P be used interchangeably with AT24C16-10PC-2.7?

A: Yes. Both parts maintain identical memory capacity (16Kbit), organization (2K x 8), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), and 8-DIP package configuration. Direct pin-for-pin substitution is supported.

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

A: Operating temperature range differs. 24AA16/P operates 0°C ~ 70°C, while 24AA16-E/P operates -40°C ~ 125°C. Both maintain identical memory specifications and I2C interface characteristics.

Q: Are there voltage supply compatibility concerns?

A: The original AT24C16-10PC-2.7 specifies 2.7V ~ 5.5V supply range. Both substitute parts (24AA16/P and 24AA16-E/P) support 1.7V ~ 5.5V, providing extended low-voltage capability. Designs operating at 2.7V or above are fully compatible.

Q: What is the significance of RoHS3 compliance on substitute parts?

A: Both active substitutes (24AA16/P and 24AA16-E/P) are ROHS3 compliant, whereas the obsolete AT24C16-10PC-2.7 is non-compliant. This compliance status is relevant for applications subject to RoHS regulatory requirements.

Q: Does package configuration remain identical across all three parts?

A: Yes. All three parts utilize 8-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and electrical compatibility on existing PCB layouts without modification.
