Substitute Part Grouping Explanation

Substitution eligibility for the PS2501-1G is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 5300Vrms
• Number of channels: 1
• Output type: Transistor
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Current transfer ratio range: 80% to 600% @ 5mA
• Package type: 4-DIP (0.400", 10.16mm)
• Mounting configuration: Through Hole
• Operating temperature range: -30°C ~ 100°C

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in circuit designs without modification to PCB layout or electrical connections.
