Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7720#560 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Output configuration: Push-pull, totem pole
• Number of channels: 1
• Data rate: 25MBd
• Common mode transient immunity: 10kV/µs minimum
• Package type: 8-SMD, Gull Wing
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Propagation delay and rise/fall time specifications

The HCPL-7720-560E meets all these parameters and is identified as a direct substitute. The primary distinction is packaging format (tape and reel versus bulk) and product status (active versus discontinued).

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7720-560E is the direct substitute for the HCPL-7720#560. Both parts share identical electrical and mechanical specifications, including isolation voltage, output topology, data rate, and timing characteristics. The HCPL-7720-560E is currently in active production status, ensuring availability for new designs and replacement inventory.

The HCPL-7720-560E offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant status of the original part. This compliance improvement may be advantageous for applications subject to regulatory requirements. Both parts maintain identical REACH and ECCN classifications.

The primary operational difference is packaging format: the HCPL-7720-560E is supplied in tape and reel format, standard for automated assembly processes, whereas the original part was supplied in bulk packaging. This distinction does not affect electrical performance or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Are the HCPL-7720#560 and HCPL-7720-560E electrically identical?

A: Yes. Both parts meet identical electrical specifications including 3750Vrms isolation, 25MBd data rate, 10kV/µs common mode transient immunity, and push-pull output configuration. Propagation delay, rise time, fall time, and supply voltage specifications are identical.

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

A: The HCPL-7720-560E differs in product status (active versus discontinued), RoHS compliance level (ROHS3 compliant versus non-compliant), and packaging format (tape and reel versus bulk). Electrical and mechanical specifications are equivalent.

Q: Can the HCPL-7720-560E be used as a direct replacement in existing designs?

A: Yes. The HCPL-7720-560E is pin-compatible and functionally equivalent. No circuit modifications are required. The 8-SMD gull wing package is identical for both parts.

Q: Does the tape and reel packaging affect circuit performance?

A: No. Packaging format does not affect electrical performance or reliability. Tape and reel packaging is standard for automated assembly and does not alter component specifications or behavior.

Q: Are there any compliance considerations when switching to the HCPL-7720-560E?

A: The HCPL-7720-560E meets ROHS3 compliance, whereas the original part does not. This may be beneficial for applications subject to RoHS regulations. Both parts maintain identical REACH and ECCN classifications.
