Substitute Part Grouping Explanation

Substitution of the PS2501-1LSMT&R is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5300Vrms (primary isolation specification)
• Number of Channels: 1 (functional architecture)
• Output Type: Transistor (switching mechanism)
• Current Transfer Ratio: 200% to 400% @ 5mA (gain specification)
• Maximum Output Voltage: 80V (voltage rating)
• Maximum Output Current: 50mA per channel (current capacity)
• Vce Saturation: 300mV (saturation characteristic)
• Package / Case: 4-SMD (0.300", 7.62mm) (physical form factor)
• Mounting Type: Surface Mount (assembly compatibility)

The PS2501-1XLSMT&R meets all these criteria and is classified as a parametric equivalent within the PS2501-1 series.
