Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-263L#520 is determined by strict equivalence across the following critical parameters:

• Number of channels: 2
• Isolation voltage: 5000Vrms
• Common mode transient immunity: 10kV/µs minimum
• Output configuration: Open collector with Schottky clamping
• Output current per channel: 50 mA
• Data rate: 15MBd
• Propagation delay: 75ns maximum (both rising and falling edges)
• Supply voltage ranges: 2.7V–3.6V and 4.5V–5.5V
• Package type: 8-SMD, Gull Wing
• Input type: DC
• Operating temperature range: -40°C to 85°C

The HCPL-263L-520E meets all these criteria and is identified as a direct manufacturer substitute.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-263L-520E is the direct substitute for the HCPL-263L#520. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the two parts is product status and regulatory compliance. The HCPL-263L#520 is discontinued and carries RoHS non-compliant status, while the HCPL-263L-520E is active and ROHS3 compliant. For new designs or systems requiring ongoing component availability, the HCPL-263L-520E is the appropriate selection. The substitute part is supplied in Tape & Reel packaging, which is standard for production environments.

Both parts maintain identical isolation voltage, propagation delay, data rate, output current capability, and supply voltage specifications, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-263L-520E be used as a direct replacement for the HCPL-263L#520?

A: Yes. The HCPL-263L-520E is electrically and mechanically equivalent to the HCPL-263L#520 across all specified parameters, including isolation voltage, data rate, propagation delay, output current, and package configuration.

Q: What is the difference between HCPL-263L#520 and HCPL-263L-520E?

A: The parts are functionally identical. The primary differences are product status (discontinued versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). The HCPL-263L-520E is supplied in Tape & Reel packaging.

Q: Are there any package differences between these parts?

A: Both parts use the same 8-SMD, Gull Wing package configuration with 8-DIP Gull Wing supplier device packaging. The HCPL-263L#520 is supplied as individual units, while the HCPL-263L-520E is supplied in Tape & Reel format.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts meet identical electrical specifications.

Q: What supply voltages are supported by the substitute part?

A: The HCPL-263L-520E supports dual supply voltage ranges: 2.7V to 3.6V and 4.5V to 5.5V, identical to the original part.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
