Substitute Part Grouping Explanation

Substitution of the HCPL-4100#500 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 3750Vrms (mandatory match)
• Channel Configuration: Single channel (mandatory match)
• Output Type: Current loop transmitter at 30mA (mandatory match)
• Input Type: Logic-level input (mandatory match)
• Common Mode Transient Immunity: 1kV/µs minimum (mandatory match)
• Propagation Delay: tpLH 1.6µs max, tpHL 1µs max (mandatory match)
• Supply Voltage Range: 4.5V ~ 20V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)
• Package Type: 8-SMD, Gull Wing (mandatory match)

The HCPL-4100-500E qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-4100-500E is the direct functional equivalent of the HCPL-4100#500. Both components share identical electrical and mechanical specifications across all critical parameters including isolation voltage, channel count, output current, propagation delay, and package configuration.

The primary distinction is product status and regulatory compliance. The HCPL-4100#500 is discontinued, while the HCPL-4100-500E maintains active production status. Additionally, the HCPL-4100-500E achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs or systems requiring ongoing component availability, the HCPL-4100-500E is the appropriate selection. For legacy systems currently using the HCPL-4100#500, the HCPL-4100-500E provides drop-in compatibility without circuit modification.
