Substitute Part Grouping Explanation

Substitution of the PS2815-4-F3-L-A is permissible when the replacement component maintains the following critical parameters:

• Number of Channels: 4
• Voltage - Isolation: 2500Vrms
• Current Transfer Ratio (Min/Max): 100% / 400% @ 1mA
• Input Type: AC, DC capable
• Output Type: Transistor
• Voltage - Output (Max): 40V
• Current - Output / Channel: 40mA
• Vce Saturation (Max): 300mV
• Operating Temperature Range: -55°C ~ 100°C
• Package / Case: 16-SOIC (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Three equivalent parts meet these requirements: PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A, all manufactured by Renesas Electronics Corporation. These parts share the same NEPOC series designation or base product number (PS2815) and maintain identical electrical characteristics within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The three substitute parts—PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A—are all manufactured by Renesas Electronics Corporation and carry Active product status, ensuring continued availability and support. All three maintain ROHS3 compliance and REACH compliance status equivalent to the original part.

The PS2815-4-F3-A provides compatibility with Cut Tape and Digi-Reel® packaging formats. The PS2815-4-V-A and PS2815-4-V-F3-A offer Strip and Tape & Reel packaging options respectively, accommodating different procurement and assembly workflows. Selection should be based on procurement requirements and existing supply chain integration rather than electrical performance, as all three alternatives deliver identical functional specifications.

Frequently Asked Questions (FAQ)

Can PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A be used interchangeably with PS2815-4-F3-L-A? Yes, all three substitute parts meet the identical electrical and mechanical specifications required for PS2815-4-F3-L-A replacement. The 4-channel configuration, 2500Vrms isolation, current transfer ratio range, rise/fall times, and 16-SOIC package dimensions remain constant across all alternatives.

What is the difference between the three substitute parts? The primary differences are packaging format and manufacturer status. PS2815-4-F3-A is supplied in Cut Tape and Digi-Reel® format. PS2815-4-V-A is supplied in Strip format. PS2815-4-V-F3-A is supplied in Tape & Reel format. All share the same NEPOC series base product number (PS2815) and deliver identical electrical performance.

Are these parts suitable for PCB assembly with automated equipment? All substitute parts employ Surface Mount technology with the standard 16-SOIC package. The Tape & Reel packaging (PS2815-4-V-F3-A) is optimized for high-volume automated assembly, while Cut Tape and Strip formats accommodate lower-volume or mixed assembly approaches.

Do these substitutes maintain the same isolation voltage rating? All substitute parts are rated for 2500Vrms isolation, matching the original PS2815-4-F3-L-A specification. This rating determines the maximum potential difference that can be safely applied between input and output circuits.

What is the significance of the Current Transfer Ratio specification? The Current Transfer Ratio of 100% (minimum) to 400% (maximum) @ 1mA defines the efficiency of signal coupling between the LED input and transistor output. All alternatives maintain this identical range, ensuring consistent circuit behavior and design margin.
