Substitute Part Grouping Explanation

Substitution of the HCPL-250L-300 is determined by the following critical parameters:

• Isolation Voltage: 3750Vrms (must match exactly)
• Number of Channels: 1 (single-channel configuration)
• Output Configuration: Transistor with Base (functional output type)
• Current Transfer Ratio Range: 19% to 50% @ 16mA (operational performance window)
• Switching Speed: 200ns turn-on, 600ns turn-off (timing characteristics)
• Output Current Capability: 8mA per channel
• Input Type: DC
• Package Type: 8-SMD, Gull Wing (mechanical and electrical interface)
• Operating Temperature Range: -55°C ~ 100°C

The 6N136-300E meets all critical substitution criteria, maintaining identical isolation voltage, channel count, output type, current transfer ratio specifications, switching times, and package configuration.
