PS8802-2-AX Optoisolator - Equivalent & Substitute Parts

Part Overview

The PS8802-2-AX is a 2-channel optoisolator with transistor output, rated for 2500Vrms isolation voltage. This component is classified as discontinued at DiGi Electronics and carries a "Not For New Designs" status from Renesas Electronics. The necessity to identify substitute parts stems from the product's discontinued status, requiring engineers to source equivalent alternatives that maintain identical electrical and mechanical performance for existing designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the PS8802-2-AX is based strictly on electrical and mechanical parameter matching. The critical parameters that determine substitute equivalence are: Number of Channels (2), Isolation Voltage (2500Vrms), Current Transfer Ratio range (15%-45% @ 16mA), switching times (300ns turn-on, 600ns turn-off), output type (Transistor), maximum output voltage (35V), output current per channel (8mA), input forward voltage (1.7V), and physical package specification (8-SOIC).

The PS8802-2-AX from Renesas Electronics Corporation qualifies as a parametric equivalent, meeting all specified electrical characteristics and mechanical requirements. Both variants share identical part number designation, isolation voltage rating, channel count, current transfer ratio specifications, switching performance, output specifications, and package dimensions. The substitute maintains full compliance with RoHS3 standards and operates across the same temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both variants of PS8802-2-AX meet identical electrical and mechanical specifications, establishing them as direct parametric equivalents. The CEL variant carries a "Discontinued at DiGi Electronics" status, while the Renesas Electronics version carries "Not For New Designs" classification. For existing designs currently using the CEL PS8802-2-AX, the Renesas Electronics PS8802-2-AX provides electrical and mechanical compatibility without circuit modification. Component selection between these variants should be based on availability, supply chain considerations, and organizational design standards. Both options maintain full compliance with RoHS3 standards and REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS8802-2-AX replace the CEL PS8802-2-AX in existing designs? A: Yes. Both variants share identical electrical specifications (isolation voltage, current transfer ratio, switching times, output ratings) and mechanical package dimensions (8-SOIC). Direct substitution is electrically and mechanically compatible.

Q: What are the critical parameters for PS8802-2-AX substitution? A: Substitution requires matching these parameters: 2-channel configuration, 2500Vrms isolation voltage, 15%-45% current transfer ratio @ 16mA, 300ns turn-on and 600ns turn-off times, transistor output type, 35V maximum output voltage, 8mA per-channel output current, and 8-SOIC surface-mount package. Deviation from any of these parameters disqualifies a component as a direct substitute.

Q: Are there package considerations for PS8802-2-AX substitution? A: Both variants utilize 8-SOIC surface-mount packaging with 0.154-inch width (3.90mm). PCB footprints and reflow profiles remain identical between variants, requiring no layout or assembly process changes.

Q: What compliance certifications apply to both variants? A: Both PS8802-2-AX variants are ROHS3 compliant and REACH affected. No compliance-based restrictions apply to either variant for equivalent applications.

Q: How do the turn-on and turn-off times affect circuit design? A: Both variants exhibit 300ns typical turn-on time and 600ns typical turn-off time, defining switching speed performance. These timing specifications are identical between variants and must be accommodated in circuit timing analysis, independent of manufacturer selection.
