Substitute Part Grouping Explanation

Substitute parts for the TLP620G are identified based on strict equivalence across the following critical parameters:

• Isolation voltage rating: 5300Vrms
• Number of channels: 1
• Current transfer ratio range: 50% to 600% @ 5mA
• Output type: Transistor
• Maximum output voltage: 55V
• Maximum output current: 50mA
• Package type: 4-DIP through-hole
• Operating temperature range: -30°C ~ 100°C
• Compliance certifications: ROHS3, REACH Unaffected

The ISP620-1XG meets all these parameters and is classified as a parametric equivalent. Both parts share identical electrical specifications, mechanical dimensions, and regulatory compliance status, making them interchangeable in applications requiring single-channel optoisolation with the specified performance characteristics.

Parameter Comparison
