Substitute Part Grouping Explanation

Substitute parts for the K817P6 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Isolation voltage rating of 5000Vrms or higher
• Single-channel configuration with transistor output
• Current transfer ratio range of 100% to 300% @ 5mA
• Maximum output voltage of 70V or greater
• Maximum output current of 50mA or greater per channel
• Turn-on and turn-off times within specified ranges (6µs and 5µs respectively)
• 4-DIP through-hole package format
• Operating temperature range encompassing -40°C to 100°C

The TCET1106 meets all these criteria and is classified as an active product, making it a direct functional equivalent to the obsolete K817P6.
