Key Parameters

Substitute Part Grouping Explanation

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

Isolation and Safety Specifications: Isolation voltage must equal 5000Vrms; number of channels must equal 1; output type must be transistor.

Electrical Performance: Current transfer ratio range (130% to 260% @ 5mA), maximum output voltage (80V), maximum output current (50mA), and Vce saturation (300mV maximum) must be identical.

Input/Output Characteristics: Input type must be DC; forward voltage (1.17V typical) and maximum DC forward current (80mA) must match.

Switching Performance: Rise and fall times (3µs and 5µs respectively) must be maintained.

Physical and Environmental Compatibility: Package must be 4-DIP (0.300", 7.62mm); mounting type must be through hole; operating temperature range must span -55°C to 100°C; RoHS3 compliance and REACH status must be maintained.

The PS2501-1-W-A manufactured by Renesas Electronics Corporation meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PS2501-1-W-A from Renesas Electronics Corporation is the direct parametric equivalent for the discontinued PS2561-1-V-W-A. All electrical, mechanical, and environmental specifications are identical. The primary distinction is product status: the PS2501-1-W-A maintains active status with confirmed inventory availability (1020 pieces), whereas the original part is discontinued.

Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The PS2501-1-W-A is supplied in tube packaging and is suitable for direct substitution in through-hole PCB applications requiring 5000Vrms isolation with single-channel transistor output.
