Key Parameters

Substitute Part Grouping Explanation

Substitution of the PC817X1NIP0F is determined by the following critical parameters:

• Single-channel optoisolator configuration
• Isolation voltage rating of 5000Vrms or higher
• Current transfer ratio range of 80% to 160% @ 5mA
• Transistor output with maximum output voltage of 80V
• Maximum output current of 50mA per channel
• DC input type
• 4-SMD surface mount package with gull wing leads
• Operating temperature range of -30°C to 100°C
• Forward voltage of 1.2V typical and maximum forward current of 50mA
• Vce saturation maximum of 200mV

The ISP817AXSMT/R meets all these criteria with an isolation voltage rating of 5300Vrms, which exceeds the minimum requirement, and maintains identical electrical performance specifications for current transfer ratio, output characteristics, and thermal operating range.

Parameter Comparison
