Substitute Part Grouping Explanation

Substitute parts for the PS2502L-1-L-A are identified based on strict parametric equivalence. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Number of Channels: 1
• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio range: 700% @ 1mA (Min) and 3400% @ 5mA (Max)
• Output Type: Darlington
• Voltage - Output (Max): 40V
• Current - Output / Channel: 200mA
• Vce Saturation (Max): 1V
• Operating Temperature range: -55°C ~ 100°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

All substitute parts listed below match these parameters exactly and are therefore functionally and mechanically interchangeable with the original PS2502L-1-L-A component.
