Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-4534#020 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio range: 15% (Min) to 50% (Max) @ 16mA
• Output Type: Transistor
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature range: -55°C ~ 100°C

The HCPL-4534-020E meets all these criteria and is therefore a direct functional equivalent. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-4534-020E is the direct substitute for the HCPL-4534#020. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters.

The HCPL-4534-020E offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the HCPL-4534-020E carries ROHS3 compliance, whereas the original HCPL-4534#020 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

For new designs or system refreshes, the HCPL-4534-020E is the appropriate selection. For legacy systems currently using the HCPL-4534#020, direct substitution with the HCPL-4534-020E is electrically and mechanically compatible without circuit modification.
