• Number of Channels: 1 channel configuration
• Output Configuration: Push-pull totem pole topology
• Common Mode Transient Immunity: 10kV/µs minimum
• Data Rate: 25MBd minimum
• Package Type: 8-DIP gull wing surface mount
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C

The HCPL-7721-360E qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7721-360E is the direct substitute for the HCPL-7721#360. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The HCPL-7721-360E offers two significant advantages:

• Product Status: Active availability ensures long-term supply chain reliability and continued manufacturer support.
• Compliance: ROHS3 compliance meets current environmental and regulatory requirements, whereas the original part is RoHS non-compliant.

For new designs or component replenishment, the HCPL-7721-360E is the appropriate selection. For legacy systems currently using the HCPL-7721#360, the substitute provides equivalent performance with enhanced compliance status.

Frequently Asked Questions (FAQ)

Q: Are the HCPL-7721#360 and HCPL-7721-360E pin-compatible?

A: Yes. Both devices use the 8-DIP gull wing surface mount package with identical pinout and electrical characteristics.

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

A: The primary differences are product status and RoHS compliance. The HCPL-7721-360E is currently active with ROHS3 compliance, while the HCPL-7721#360 is discontinued and RoHS non-compliant. Electrical performance and package configuration are identical.

Q: Can I use the HCPL-7721-360E as a direct replacement in existing designs?

A: Yes. The HCPL-7721-360E maintains all electrical specifications, timing characteristics, and package dimensions of the original part, enabling direct substitution without circuit modification.

Q: What packaging options are available for the substitute part?

A: The HCPL-7721-360E is supplied in tube packaging, whereas the original part number does not specify packaging format.

Q: Are there any compliance differences I should consider?

A: The HCPL-7721-360E is ROHS3 compliant and REACH unaffected. The original HCPL-7721#360 is RoHS non-compliant. For applications subject to environmental regulations, the substitute part meets current compliance requirements.
