Substitute Part Grouping Explanation

Substitution of the ACPL-K453-020E is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio range: 19% to 50% @ 16mA
• Turn On / Turn Off Time: 200ns, 600ns
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Package / Case: 8-SOIC (0.268", 6.81mm Width)
• Operating Temperature range: -55°C ~ 100°C

The ACPL-K453-000E meets all these parameters and qualifies as a parametric equivalent. The primary distinction between these parts is product status and packaging format.
