Substitute Part Grouping Explanation

Substitution for the HCPL-0730#500 is determined by strict equivalence across the following critical parameters:

• Number of channels: 2
• Isolation voltage rating: 3750Vrms
• Current transfer ratio range: 300% to 2600% @ 1.6mA
• Output configuration: Darlington
• Maximum output voltage: 7V
• Output current per channel: 60mA
• Switching time characteristics: 5µs turn-on, 10µs turn-off
• Package type: 8-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C

The HCPL-0730-500E meets all these parameters identically, establishing it as a direct parametric equivalent. Differences exist only in packaging format and product status.
