Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2913-1-AX is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 2500Vrms isolation rating is the primary functional requirement for galvanic separation in the application circuit.

Channel Configuration: Single channel (1 channel) architecture must be maintained for circuit topology compatibility.

Output Configuration: Transistor output type ensures compatible signal switching characteristics and load driving capability.

Current Transfer Ratio: Range of 50% to 200% @ 1mA defines the optical coupling efficiency and input-to-output signal transfer characteristics.

Output Specifications: Maximum output voltage of 120V and output current of 30mA per channel establish the load-driving capability boundaries.

Temperature Range: Operating range of -55°C to 100°C defines the thermal operating envelope.

Package Compatibility: 4-SMD flat lead package with surface mount mounting type ensures mechanical and electrical compatibility with existing PCB layouts.

Compliance Standards: ROHS3 compliance and REACH unaffected status maintain regulatory alignment.

Substitute parts must match all parameters listed above without deviation. No parameter relaxation or upgrade is permitted in this substitution analysis.
