CAV24C Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
CAV24C is a onsemi order-code family — not a single orderable MPN. This page lists 11 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
2Kb EEPROM I2C Serial SOIC 8-Pin 2.5-5.5V 400kHz Other listed variants describe: EEPROM Serial 2-Kb I<sup>2</sup>C - Automotive Grade, TSSOP8, 4.4x3, 3000-REEL; 4Kb EEPROM I2C Serial SOIC 8-Pin 5.5V 400kHz Surface Mount.
Across listed variants, watch these parameters: packages: 8-TSSOP (0.173", 4.40mm Width).
Suffix examples in this family: 02WE-GT3, 02YE-GT3, 04WE-GT3, 08YE-GT3, 16WE-GT3, 32C4CTR, 32WE-GT3, 512WE-GT3. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: CAV24C02WE-GT3, CAV24C02YE-GT3, CAV24C04WE-GT3, CAV24C08YE-GT3, CAV24C16WE-GT3, CAV24C32C4CTR.
Key Features
- Footprint / package: 8-TSSOP (0.173", 4.40mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 11 distinct suffix patternsExamples: 02WE-GT3, 02YE-GT3, 04WE-GT3, 08YE-GT3, 16WE-GT3 (+6 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on CAV24C map to package, grade, and reel options.
CAV24C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 02WE-GT3, 02YE-GT3, 04WE-GT3, 08YE-GT3, 16WE-GT3, 32C4CTR, 32WE-GT3, 512WE-GT3, 512YE-GT3, 64WE-GT3 (+1 more).
Full MPN examples: CAV24C02WE-GT3, CAV24C02YE-GT3, CAV24C04WE-GT3, CAV24C08YE-GT3, CAV24C16WE-GT3.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right CAV24C Microcontrollers
Match the footprint first
Packages here: 8-TSSOP (0.173", 4.40mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For CAV24C, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "CAV24C" — include the full suffix (e.g. 02WE-GT3, 02YE-GT3, 04WE-GT3). RFQ with reel/tube preference and required date code.
