Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-7710-520 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 1
• Voltage - Isolation: 5000Vrms
• Common Mode Transient Immunity (Min): 10kV/µs
• Input Type: Logic
• Output Type: Push-Pull, Totem Pole
• Current - Output / Channel: 10 mA
• Data Rate: 12.5MBd
• Propagation Delay tpLH / tpHL (Max): 40ns, 40ns
• Rise / Fall Time (Typ): 13ns, 5ns
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 100°C
• Package / Case: 8-SMD, Gull Wing

The HCPL-7710-520E meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7710-520E is the direct substitute for the HCPL-7710-520. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in all applications.

The HCPL-7710-520E is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance. The original HCPL-7710-520 is discontinued and should be replaced with the HCPL-7710-520E to ensure long-term supply chain stability and regulatory compliance.

The primary difference between the two parts is packaging format: the HCPL-7710-520E is supplied in Tape & Reel format, which is standard for production environments, whereas the original part was supplied in bulk packaging.
