HCPL-7723-500 Equivalent & Substitute Parts

Part Overview

The HCPL-7723-500 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. It provides 3750Vrms isolation with 50MBd data rate and push-pull totem pole output configuration in an 8-DIP gull wing surface mount package. The part is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7723-500 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Common mode transient immunity: 10kV/µs minimum
• Output configuration: Push-pull, totem pole
• Data rate: 50MBd
• Output current per channel: 10 mA
• Propagation delay: 22ns maximum (both rising and falling edges)
• Rise and fall time specifications: 8ns and 6ns typical
• Supply voltage range: 4.5V to 5.5V
• Package type: 8-SMD, gull wing
• Operating temperature range: -40°C to 85°C

The HCPL-7723-500E meets all these parameters and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7723-500E is the direct functional equivalent of the HCPL-7723-500. Both parts share identical electrical and mechanical specifications across all critical isolation, timing, and output parameters. The primary distinction is product status and compliance posture: the HCPL-7723-500 is discontinued, while the HCPL-7723-500E remains in active production with ROHS3 compliance certification. For new designs or ongoing procurement, the HCPL-7723-500E is the appropriate selection. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-7723-500E directly replace the HCPL-7723-500 in existing designs?

A: Yes. The HCPL-7723-500E is electrically and mechanically identical to the HCPL-7723-500 across all specified parameters, including isolation voltage, data rate, propagation delay, output current, and package configuration. Pin-for-pin compatibility is maintained.

Q: What is the difference between the HCPL-7723-500 and HCPL-7723-500E?

A: The primary differences are product status and compliance. The HCPL-7723-500 is discontinued, while the HCPL-7723-500E is active production. The HCPL-7723-500E carries ROHS3 compliance certification, whereas the HCPL-7723-500 is RoHS non-compliant. Packaging differs: the HCPL-7723-500E is supplied in tape and reel format.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts specify identical propagation delay (22ns maximum for both rising and falling edges), rise time (8ns typical), and fall time (6ns typical). All electrical performance parameters are equivalent.

Q: What isolation voltage does this optoisolator provide?

A: Both the HCPL-7723-500 and HCPL-7723-500E provide 3750Vrms isolation with 10kV/µs common mode transient immunity.

Q: Is the 8-DIP gull wing package suitable for automated assembly?

A: Yes. The 8-SMD gull wing package is designed for surface mount assembly and is compatible with standard pick-and-place and reflow soldering processes.
