HCPL-7710#500 Equivalent & Substitute Parts

Part Overview

The HCPL-7710#500 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. It provides 3750Vrms isolation with push-pull totem pole output configuration and supports data rates up to 12.5MBd. The device is currently discontinued at DiGi Electronics, making identification of equivalent parts essential for ongoing system support and new designs requiring this isolation topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7710#500 is determined by strict equivalence across the following critical parameters:

• Single-channel configuration with logic input and push-pull totem pole output
• Isolation voltage of 3750Vrms
• Common mode transient immunity of 10kV/µs minimum
• Data rate of 12.5MBd
• Output current of 10 mA per channel
• Propagation delay specifications of 40ns maximum for both rising and falling edges
• Supply voltage range of 4.5V to 5.5V
• 8-pin surface mount package with gull wing leads
• Operating temperature range of -40°C to 100°C

The HCPL-7710-500E meets all these parameters and qualifies as a direct substitute. Differences in product status and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7710-500E is the direct equivalent for the discontinued HCPL-7710#500. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the HCPL-7710-500E is currently active with higher inventory availability (5955 units in stock versus 808 units for the original part). Additionally, the HCPL-7710-500E carries ROHS3 compliance, whereas the HCPL-7710#500 is RoHS non-compliant. This compliance difference may be relevant for applications subject to RoHS regulations.

For new designs or system replacements, the HCPL-7710-500E is the appropriate selection. For legacy systems currently using the HCPL-7710#500, direct substitution is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-7710-500E be used as a direct replacement for the HCPL-7710#500?

A: Yes. Both parts are identical in electrical performance and mechanical form factor. No circuit changes are required for substitution.

Q: What is the difference between HCPL-7710#500 and HCPL-7710-500E?

A: The parts are electrically equivalent. The primary differences are product status (discontinued versus active), packaging format (standard versus cut tape/Digi-Reel), and RoHS compliance status (non-compliant versus ROHS3 compliant).

Q: Are there any compatibility concerns with the 8-DIP gull wing package?

A: No. Both parts use the same 8-SMD gull wing surface mount package. PCB footprints and assembly processes are identical.

Q: What isolation voltage does this optoisolator provide?

A: Both the HCPL-7710#500 and HCPL-7710-500E provide 3750Vrms isolation with 10kV/µs common mode transient immunity.

Q: What is the maximum data rate supported?

A: The maximum data rate is 12.5MBd for both parts, with propagation delay specifications of 40ns maximum for both rising and falling edges.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance is relevant only if your application or regulatory environment requires it. The HCPL-7710-500E is ROHS3 compliant, while the HCPL-7710#500 is not. Electrical performance is unaffected by this distinction.
