Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL-SCSI285KCE3 is determined by strict equivalence across the following critical parameters:

• Output voltage: 2.85V fixed
• Output current capability: 620mA minimum
• Input voltage rating: 5.5V maximum
• Dropout voltage: 0.8V @ 620mA maximum
• Package type: TO-220-3 through-hole
• Protection features: Over current, over temperature, over voltage
• Operating temperature range: 0°C ~ 125°C
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The TL-SCSI285KCSE3 meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement in applications currently using the obsolete TL-SCSI285KCE3.

Parameter Comparison

Engineering Selection Recommendations

The TL-SCSI285KCSE3 is the direct substitute for the obsolete TL-SCSI285KCE3. Both parts share identical electrical specifications, thermal performance characteristics, and regulatory compliance status. The primary distinction is product lifecycle status: the TL-SCSI285KCE3 is obsolete, while the TL-SCSI285KCSE3 maintains active production status. The substitute part is supplied in tube packaging, whereas the original part was supplied without specified packaging designation. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.
