HCPL-7723-520 Equivalent & Substitute Parts

Part Overview

The HCPL-7723-520 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. It provides 5000Vrms isolation with push-pull totem pole output configuration, supporting data rates up to 50MBd and common mode transient immunity of 10kV/µs. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-7723-520 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 1
• Voltage - Isolation: 5000Vrms
• Common Mode Transient Immunity (Min): 10kV/µs
• Input Type: Logic
• Output Type: Push-Pull, Totem Pole
• Current - Output / Channel: 10 mA
• Data Rate: 50MBd
• Propagation Delay tpLH / tpHL (Max): 22ns, 22ns
• Rise / Fall Time (Typ): 8ns, 6ns
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing

The HCPL-7723-520E meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7723-520E is the direct substitute for the HCPL-7723-520. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary differences are product status and compliance certifications. The HCPL-7723-520E is currently active in production and carries ROHS3 compliance, whereas the original part is discontinued and RoHS non-compliant. For new designs and ongoing production requiring this optoisolator specification, the HCPL-7723-520E is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-7723-520E be used as a direct replacement for the HCPL-7723-520?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including isolation voltage, data rate, propagation delay, output current, and package configuration.

Q: What is the difference between the HCPL-7723-520 and HCPL-7723-520E?

A: The primary differences are product status and packaging format. The HCPL-7723-520E is currently active in production and supplied in Tape & Reel format, while the HCPL-7723-520 is discontinued and supplied in bulk packaging. The HCPL-7723-520E also carries ROHS3 compliance.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the 8-DIP Gull Wing package with identical pin assignments and electrical characteristics.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The identical 8-SMD Gull Wing package and surface mount configuration allow direct substitution in PCB designs without layout modifications.

Q: What is the significance of the RoHS compliance difference?

A: The HCPL-7723-520E meets ROHS3 compliance standards, making it suitable for applications and markets requiring RoHS-compliant components. The original HCPL-7723-520 does not meet these standards.
