Substitute Part Grouping Explanation

Substitute parts for the AD4021BCPZ-RL7 are identified through strict parametric matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

  • Resolution: 20-bit
  • Sampling Rate: 1 Megasample per second
  • Input Configuration: Single differential input
  • Architecture: SAR topology
  • Digital Interfaces: DSP, MICROWIRE™, QSPI™, and SPI™
  • Reference Configuration: External reference
  • Supply Voltage Ranges: Analog 1.71V–1.89V, Digital 1.71V–5.5V
  • Operating Temperature: -40°C to 125°C
  • Package: 10-LFCSP-WD (3x3) with exposed pad
  • Compliance: RoHS3 and REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct functional substitutes.
