Substitute Part Grouping Explanation

Substitution of the PS2801-1-F3-L-A is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 2500Vrms isolation rating is mandatory for applications requiring this voltage barrier.

Channel Configuration: Single-channel architecture must be maintained.

Output Configuration: Transistor output type with identical electrical characteristics.

Current Transfer Ratio: Range of 100% to 300% @ 5mA input current.

Maximum Output Specifications: 80V maximum output voltage and 50mA maximum output current per channel.

Thermal Range: Operating temperature range of -55°C to 100°C.

Package Compatibility: 4-SOIC (4-SSOP) surface mount package with 0.173" width (4.40mm).

Input Type: DC input operation.

The PS2801-1-L-A manufactured by Renesas Electronics Corporation meets all specified parameters and serves as a direct functional equivalent.
