Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-7723-300 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 1
• Voltage - Isolation: 3750Vrms
• Common Mode Transient Immunity (Min): 10kV/µs
• Input Type: Logic
• Output Type: Push-Pull, Totem Pole
• Current - Output / Channel: 10 mA
• Data Rate: 50MBd
• Propagation Delay tpLH / tpHL (Max): 22ns, 22ns
• Rise / Fall Time (Typ): 8ns, 6ns
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing

Only parts matching all these parameters across the base product number HCPL-7723 are considered direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-7723-300 and HCPL-7723-300E are functionally equivalent across all electrical and mechanical parameters. The primary distinction is regulatory compliance status. The HCPL-7723-300E carries ROHS3 compliance certification, while the HCPL-7723-300 is RoHS non-compliant. Selection between these parts should be based on application requirements for environmental compliance and regulatory jurisdiction. The HCPL-7723-300E offers higher inventory availability at 2000 pieces compared to 900 pieces for the HCPL-7723-300.

Frequently Asked Questions (FAQ)

Q: Are HCPL-7723-300 and HCPL-7723-300E pin-for-pin compatible?
