Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2561-1-H-A is determined by strict equivalence across the following critical parameters:

Isolation and Electrical Performance:

• Isolation voltage rating of 5000Vrms
• Single-channel configuration
• Current transfer ratio range of 80% to 160% @ 5mA
• Transistor output type with maximum output voltage of 80V and 50mA per-channel current capacity
• Vce saturation maximum of 300mV

Switching Characteristics:

• Rise and fall times of 3µs and 5µs respectively
• DC input type

Physical and Environmental Compatibility:

• 4-DIP package with 0.300" (7.62mm) pitch for through-hole mounting
• Operating temperature range of -55°C to 100°C
• RoHS3 compliance and REACH compliance status

The PS2501-1-H-A meets all these criteria and qualifies as a parametric equivalent substitute.
