Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-3020-500 is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 3750Vrms
• Single-channel configuration
• Common mode transient immunity: 10kV/µs minimum
• Propagation delay specifications: 700ns maximum (both tpLH and tpHL)
• Output current capability: 400mA peak, 200mA high/low
• Output supply voltage range: 10V ~ 30V
• Operating temperature range: -40°C ~ 100°C
• 8-pin DIP Gull Wing package configuration
• Optical coupling technology

The HCPL-3020-500E qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3020-500E is the direct functional equivalent of the HCPL-3020-500. Both components share identical electrical specifications, isolation ratings, and package configurations. Selection between these parts is determined by availability and compliance requirements rather than technical performance.

The HCPL-3020-500E is recommended for new designs and ongoing procurement due to its active product status. This part maintains full compatibility with existing circuit designs specified for the HCPL-3020-500.

The HCPL-3020-500E achieves ROHS3 compliance, whereas the original HCPL-3020-500 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. Both parts carry CSA and UR approvals.

Packaging format differs between the two parts: the HCPL-3020-500 is supplied in bulk format, while the HCPL-3020-500E is supplied in Tape & Reel (TR) format. This affects procurement quantities and handling procedures but does not impact electrical performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3020-500E be used as a direct replacement for the HCPL-3020-500?

A: Yes. The HCPL-3020-500E is electrically and mechanically identical to the HCPL-3020-500. All electrical parameters, isolation ratings, output current specifications, and timing characteristics are equivalent. The 8-pin DIP Gull Wing package configuration is identical, ensuring PCB footprint compatibility.

Q: What is the primary difference between these two parts?

A: The HCPL-3020-500 is discontinued, while the HCPL-3020-500E is active. The HCPL-3020-500E also achieves ROHS3 compliance. Packaging format differs: bulk versus Tape & Reel (TR).

Q: Are there any circuit design modifications required when switching from HCPL-3020-500 to HCPL-3020-500E?

A: No circuit modifications are required. The parts are pin-compatible and electrically equivalent. Existing designs require no changes.
