Substitute Part Grouping Explanation

Substitution of the HCPL-M456#500 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part HCPL-M456-500E maintains identical specifications in the following key areas:

• Single channel configuration with DC input
• 3750Vrms isolation voltage
• 15kV/µs common mode transient immunity
• Open collector Schottky clamped output topology
• 15 mA output current per channel
• Identical propagation delay characteristics (550ns, 400ns)
• Matching forward voltage and forward current specifications
• 4.5V to 30V supply voltage range
• -40°C to 100°C operating temperature range
• Identical 6-SOIC 5-lead surface mount package

The substitute part differs only in product status (active vs. discontinued) and RoHS compliance level, with no functional or electrical parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-M456-500E is a direct functional equivalent to the HCPL-M456#500. Selection of the substitute part is justified by the following factors:
