Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-3020-300 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 3750Vrms minimum
• Number of Channels: 1 channel configuration
• Common Mode Transient Immunity: 10kV/µs minimum
• Propagation Delay: 700ns maximum (tpLH and tpHL)
• Peak Output Current: 400mA
• Output Supply Voltage Range: 10V ~ 30V
• Package Configuration: 8-SMD, Gull Wing
• Technology: Optical Coupling

The HCPL-3020-300E qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters. The primary distinction is product status and compliance certification.
