PS2806-4-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2806-4-A is a 4-channel optoisolator with Darlington output configuration, rated for 2500Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits with moderate current switching capability. The PS2806-4-A from CEL is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS2806-4-A is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 4 channels required
• Isolation Voltage: 2500Vrms minimum
• Output Configuration: Darlington output topology
• Current Transfer Ratio: 200% @ 1mA minimum
• Maximum Output Voltage: 40V
• Output Current per Channel: 100mA
• Package Type: 16-SOIC surface mount
• Operating Temperature Range: -55°C to 100°C
• Compliance: ROHS3 compliant

Substitute parts must match all specified electrical parameters and physical package dimensions to ensure direct replacement without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

The PS2806-4-A manufactured by Renesas Electronics Corporation is electrically and mechanically equivalent to the CEL PS2806-4-A. Both variants share identical electrical specifications, package dimensions, and compliance certifications (ROHS3, REACH Affected).

The Renesas variant carries a "Not For New Designs" status, indicating limited long-term availability. For applications requiring the PS2806-4-A optoisolator, component selection should prioritize current inventory status and supplier lead times. Both parts are suitable for existing production support and maintenance applications where the specific electrical and isolation characteristics are required.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2806-4-A directly replace the CEL PS2806-4-A?

A: Yes. Both parts are electrically identical across all specified parameters and use the same 16-SOIC package. No circuit modifications or PCB changes are required for substitution.

Q: What determines if an optoisolator can substitute for the PS2806-4-A?

A: Substitution requires matching all critical parameters: 4-channel configuration, 2500Vrms isolation voltage, Darlington output, 200% minimum current transfer ratio, 40V maximum output voltage, 100mA per-channel output current, 16-SOIC package, and -55°C to 100°C operating temperature range.

Q: Why is the CEL PS2806-4-A discontinued?

A: The part is discontinued at DiGi Electronics. Availability through alternative distributors or direct manufacturer channels should be evaluated for procurement planning.

Q: Are there differences in packaging between the two variants?

A: The CEL variant is supplied in standard packaging, while the Renesas variant is supplied in Strip packaging. Both use the 16-SOIC (0.173", 4.40mm Width) case. Strip packaging affects handling and tape-and-reel compatibility but does not affect electrical performance or PCB mounting.

Q: What compliance certifications apply to both parts?

A: Both the CEL and Renesas PS2806-4-A variants are ROHS3 compliant, REACH affected, and carry Moisture Sensitivity Level 1 (unlimited shelf life). ECCN classification is EAR99 for both parts.
