Substitute Part Grouping Explanation

Substitution of the TL-SCSI285KC is determined by strict equivalence across the following critical parameters:

  • Output voltage: 2.85V fixed
  • Maximum output current: 620mA
  • Maximum input voltage: 5.5V
  • Maximum dropout voltage: 0.8V @ 620mA
  • Package type: TO-220-3 through-hole mounting
  • Protection features: Over Current, Over Temperature, Over Voltage
  • Operating temperature range: 0°C ~ 125°C
  • PSRR performance: 62dB (120Hz)

The TL-SCSI285KCSE3 meets all these electrical and mechanical specifications, making it a direct functional equivalent. The primary distinction is product status: TL-SCSI285KCSE3 is active production, whereas TL-SCSI285KC is obsolete.
