Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-7710-320 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 5000Vrms
• Common mode transient immunity: 10kV/µs minimum
• Output configuration: Push-pull, totem pole
• Data rate: 12.5MBd
• Output current per channel: 10 mA
• Propagation delay: 40ns maximum (both tpLH and tpHL)
• Supply voltage range: 4.5V to 5.5V
• Package type: 8-SMD, gull wing
• Number of channels: 1
• Input type: Logic

The HCPL-7710-320E meets all these criteria and is classified as a direct substitute. Both parts share identical electrical and mechanical specifications, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7710-320E is the direct substitute for the HCPL-7710-320. Both parts are electrically and mechanically identical across all specified parameters. The HCPL-7710-320E is currently in active production status, whereas the original part is discontinued.

For new designs or production continuity, the HCPL-7710-320E is the appropriate selection. The substitute part offers the additional advantage of ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-7710-320E be used as a direct replacement for the HCPL-7710-320?

A: Yes. The HCPL-7710-320E is electrically and mechanically equivalent. All critical parameters including isolation voltage, CMTI, data rate, propagation delay, output current, and package configuration are identical. Pin-for-pin compatibility is maintained.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The HCPL-7710-320 is discontinued, while the HCPL-7710-320E is active. The HCPL-7710-320E is ROHS3 compliant, whereas the original is RoHS non-compliant. Packaging format differs (tube versus unspecified), but the component itself is identical.

Q: Are there any performance differences between these parts?

A: No. Both parts meet identical electrical specifications for isolation voltage (5000Vrms), common mode transient immunity (10kV/µs), data rate (12.5MBd), propagation delay (40ns), output current (10 mA), and operating temperature range (-40°C to 100°C).

Q: Is the 8-DIP gull wing package compatible with standard PCB layouts?

A: Yes. The 8-SMD gull wing package is a surface mount configuration designed for standard PCB assembly processes. Both the HCPL-7710-320 and HCPL-7710-320E use this identical package type.

Q: Why should I choose the HCPL-7710-320E over the original part?

A: The HCPL-7710-320E is the active production part with current availability. It provides ROHS3 compliance for regulatory alignment with modern environmental standards. For supply chain continuity and new production runs, the HCPL-7710-320E is the appropriate selection.
