Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-4506#320 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Open Collector, Schottky Clamped (mandatory match)
• Common Mode Transient Immunity: 15kV/µs minimum (mandatory match)
• Input Type: DC (mandatory match)
• Package Type: 8-SMD, Gull Wing (mandatory match)
• Electrical Performance: Propagation delay, forward voltage, output current, and supply voltage range must remain within specified limits

The HCPL-4506-320E qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-4506-320E is the direct substitute for the discontinued HCPL-4506#320. Both parts share identical electrical specifications, channel configuration, isolation voltage, and package type, ensuring pin-for-pin and functional compatibility.

The HCPL-4506-320E offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the HCPL-4506-320E meets ROHS3 compliance requirements, whereas the original HCPL-4506#320 is RoHS non-compliant. This compliance improvement aligns with current regulatory standards for electronic components in manufacturing and end-of-life disposal.

Both parts maintain identical performance characteristics across propagation delay, output current, forward voltage, and operating temperature range, confirming full functional interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-4506-320E be used as a direct replacement for the HCPL-4506#320?

A: Yes. The HCPL-4506-320E is a direct substitute. Both parts are manufactured by Broadcom Limited and share identical electrical specifications, channel count, isolation voltage, output configuration, and 8-SMD gull wing package type. No circuit modifications are required.

Q: What is the difference between HCPL-4506#320 and HCPL-4506-320E?

A: The primary differences are product status and compliance certification. The HCPL-4506#320 is discontinued and RoHS non-compliant. The HCPL-4506-320E is an active product that meets ROHS3 compliance standards. Electrical performance and package configuration are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-SMD gull wing package with identical pinout and mechanical dimensions. The HCPL-4506-320E is supplied in tube packaging, whereas the original part number does not specify packaging format.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by matching isolation voltage (5000Vrms), channel count (1), output type (open collector Schottky clamped), common mode transient immunity (15kV/µs), input type (DC), and package configuration (8-SMD gull wing). All electrical performance parameters including propagation delay, forward voltage, output current, and supply voltage range must remain within specification.

Q: Is the HCPL-4506-320E suitable for new designs?

A: Yes. The HCPL-4506-320E is an active product with current manufacturing support. Its ROHS3 compliance makes it suitable for new designs and applications subject to environmental and regulatory requirements.
