Key Parameters

Substitute Part Grouping Explanation

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

• Number of channels: 2
• Isolation voltage: 5000Vrms
• Common mode transient immunity: 1kV/µs minimum
• Output configuration: Open collector with Schottky clamping
• Output current per channel: 50 mA
• Data rate: 10MBd
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package type: 8-SMD, Gull Wing

The HCPL-263A-520E meets all these parameters and qualifies as a direct substitute. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-263A-520E is the direct substitute for the HCPL-263A-520. Both parts are electrically and mechanically identical across all specified parameters. The key differentiators are:

• Product Status: The HCPL-263A-520 is discontinued at DiGi Electronics, while the HCPL-263A-520E is active and available.
• RoHS Compliance: The HCPL-263A-520 is RoHS non-compliant, while the HCPL-263A-520E is ROHS3 compliant.
• Packaging Format: The HCPL-263A-520E is supplied in Tape & Reel (TR) format, which is standard for production environments.

For new designs or ongoing production requiring this optoisolator function, the HCPL-263A-520E is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-263A-520E replace the HCPL-263A-520 in existing designs?

A: Yes. The HCPL-263A-520E is electrically and mechanically equivalent. All electrical parameters, timing characteristics, and package dimensions are identical. Direct substitution is possible without circuit modification.

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

A: The primary differences are product status (discontinued vs. active), RoHS compliance level (non-compliant vs. ROHS3 compliant), and packaging format (individual vs. Tape & Reel). Electrical and functional specifications are identical.

Q: Are there any compatibility concerns with the 8-SMD Gull Wing package?

A: No. Both parts use the same 8-SMD Gull Wing package. PCB footprints, solder reflow profiles, and assembly processes are compatible.

Q: Why is the HCPL-263A-520 discontinued?

A: The HCPL-263A-520E is the active production variant. Broadcom has consolidated the product line to the ROHS3-compliant version with standard Tape & Reel packaging.

Q: What are the key isolation and speed specifications that define this part family?

A: The defining specifications are 5000Vrms isolation voltage, 1kV/µs common mode transient immunity, 10MBd data rate, and 2-channel configuration with open collector outputs. These parameters determine functional equivalence for substitution purposes.
