Substitute Part Grouping Explanation

Substitute parts for the 24LC04BHT-E/ST are qualified based on the following critical parameters:

• Memory capacity: 4Kbit EEPROM
• Interface protocol: I2C at 400 kHz clock frequency
• Electrical performance: 900 ns access time, 5ms write cycle time
• Supply voltage compatibility: 2.5V ~ 5.5V operating range
• Temperature rating: -40°C ~ 125°C
• Package format: 8-TSSOP surface mount configuration
• Regulatory compliance: RoHS3 compliance and REACH unaffected status

The CAV24C04YE-GT3 manufactured by onsemi meets all specified electrical and mechanical parameters. While memory organization differs (512 x 8 versus 256 x 8 x 2), both configurations deliver equivalent 4Kbit capacity. The onsemi part includes automotive-grade qualification (AEC-Q100), providing additional reliability certification for applications requiring enhanced quality assurance.
