AI Summary

CAT24C32 by onsemi: EEPROM 32KB I2C SER EEPROM.

This is a direct, drop-in replacement from STMicroelectronics that fully matches the CAT24C32 in footprint, pin assignments, operating voltage, and 1 MHz clock speed. It is a highly reliable alternative from a major manufacturer.

  • Pin-compatible drop-in replacement in standard 8-SOIC package
  • Supports high-speed Fast-Plus I2C protocol up to 1 MHz
  • Identical wide operating voltage range from 1.7V to 5.5V

A high-performance second-source from Microchip Technology that serves as a direct drop-in replacement. It maintains complete functional, electrical, and physical parity with the original onsemi part.

  • Pin-compatible drop-in replacement in standard 8-SOIC package
  • Full-speed 1 MHz I2C clock support from 1.7V to 5.5V
  • Excellent ESD protection and low-power CMOS technology

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
