Engineering Selection Recommendations

The Renesas Electronics Corporation version of the PS2381-1Y-V-M-AX is the direct parametric equivalent and substitute for the discontinued CEL device. Both variants meet identical electrical specifications and maintain ROHS3 and REACH compliance. The Renesas part is currently in active production status, providing supply chain continuity for applications requiring the PS2381-1Y-V-M-AX optoisolator. No design modifications or board-level changes are required for substitution.

Frequently Asked Questions (FAQ)

Q: What makes the Renesas PS2381-1Y-V-M-AX a suitable substitute? A: The Renesas variant is an exact parametric match. It maintains identical isolation voltage (5000Vrms), current transfer ratio specifications (50-150% @ 5mA), output characteristics (80V, 50mA), and mechanical package dimensions (4-LSOP 2.54mm). Both comply with ROHS3 and REACH regulations.

Q: Are there any package or pinout differences? A: Both versions use the identical 4-SMD gull wing package (4-LSOP 2.54mm). Pin assignments and mechanical footprints are functionally compatible for direct PCB substitution.

Q: Can the Renesas part be used as a drop-in replacement? A: Yes. The electrical and mechanical specifications are identical. No circuit modifications or component rework is necessary.

Q: What compliance certifications apply to both parts? A: Both variants are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
