Key Parameters

Substitute Part Grouping Explanation

The HCPL-263L#300 has one direct substitute: HCPL-263L-300E. This substitution is valid based on the following criteria:

Both parts share identical electrical specifications across all critical parameters: 2-channel configuration, 3750Vrms isolation voltage, 10kV/µs common mode transient immunity, 15MBd data rate, 75ns maximum propagation delay, open collector Schottky clamped output topology, 50mA output current per channel, and dual supply voltage ranges (2.7V-3.6V and 4.5V-5.5V). Both devices operate across the same temperature range (-40°C to 85°C) and use identical 8-SMD Gull Wing packaging with surface mount configuration.

The key differentiator is product status and compliance: HCPL-263L#300 is discontinued, while HCPL-263L-300E is active with ROHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

HCPL-263L-300E is the direct substitute for HCPL-263L#300. Selection of HCPL-263L-300E is based on:
