Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-261A#060 is determined by strict equivalence across the following critical parameters:

• Single channel configuration with 1 input and 0 side 2 inputs
• 3750Vrms isolation voltage
• 1kV/µs common mode transient immunity
• Open collector Schottky clamped output topology
• 50 mA output current per channel
• 10MBd data rate capability
• 8-DIP through-hole package format
• DC input type
• 4.5V to 5.5V supply voltage range
• -40°C to 85°C operating temperature range

The HCPL-261A-060E meets all these criteria as a direct functional equivalent, with the primary distinction being packaging format (tube versus bulk) and product status (active versus discontinued).

Parameter Comparison

Engineering Selection Recommendations

The HCPL-261A-060E is the direct equivalent for the discontinued HCPL-261A#060. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional interchangeability in circuit designs.

The HCPL-261A-060E offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the HCPL-261A-060E carries ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

The packaging difference (tube for HCPL-261A-060E versus bulk for HCPL-261A#060) does not affect electrical performance or mechanical fit in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-261A-060E be used as a direct replacement for the HCPL-261A#060?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including isolation voltage, output current, data rate, propagation delay, and package dimensions. The 8-DIP through-hole footprint is identical, enabling direct PCB substitution.

Q: What is the difference between HCPL-261A#060 and HCPL-261A-060E?

A: The primary differences are product status and packaging format. The HCPL-261A#060 is discontinued, while the HCPL-261A-060E is active. The HCPL-261A-060E is supplied in tube packaging, whereas the original may have been supplied in bulk. The HCPL-261A-060E also carries ROHS3 compliance.

Q: Are there any circuit design modifications required when switching from HCPL-261A#060 to HCPL-261A-060E?

A: No circuit modifications are required. The electrical specifications, pin configuration, and functional behavior are identical. The parts are direct substitutes.

Q: Does the tube packaging of HCPL-261A-060E affect handling or installation?

A: Tube packaging is standard for component distribution and does not affect the component itself. Installation procedures and PCB mounting remain unchanged from the original part.

Q: Is RoHS3 compliance relevant for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and certain other markets. If your application or end market requires RoHS compliance, the HCPL-261A-060E is the appropriate choice over the non-compliant HCPL-261A#060.
