Substitute Part Grouping Explanation

Substitution of the PS2806-1-F3-A is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Configuration: Darlington (mandatory match)
• Current Transfer Ratio: 200% @ 1mA minimum (mandatory match)
• Maximum Output Voltage: 40V (mandatory match)
• Maximum Output Current: 90mA per channel (mandatory match)
• Rise/Fall Time: 200µs typical for both (mandatory match)
• Input Type Capability: AC and DC (mandatory match)
• Package Footprint: 4-SOIC 0.173" width, 4.40mm (mandatory match for PCB compatibility)
• Operating Temperature Range: -55°C to 100°C (mandatory match)

The substitute part identified maintains electrical equivalence across all specified parameters. Package variations (4-SOIC vs. 4-SSOP) represent different supplier designations for the same physical footprint and pin configuration.

Parameter Comparison

Engineering Selection Recommendations

The PS2806-1-F3-A manufactured by Renesas Electronics Corporation is a parametric equivalent to the CEL PS2806-1-F3-A. Both parts share identical electrical specifications, isolation ratings, output characteristics, and thermal operating ranges. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CEL part is discontinued at DiGi Electronics. The Renesas equivalent maintains full electrical and mechanical compatibility for direct substitution in existing designs. The Renesas part carries a "Not For New Designs" status, indicating it represents a legacy product line. Selection between these parts should be based on current availability, supply chain requirements, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2806-1-F3-A replace the CEL PS2806-1-F3-A in existing designs?

A: Yes. Both parts are parametrically equivalent across all specified electrical and mechanical parameters. The 4-SOIC package footprint is identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference between 4-SOIC and 4-SSOP package designations?

A: Both designations refer to the same physical package with 0.173" width and 4.40mm body dimension. The variation in nomenclature reflects different supplier documentation standards. Pin configuration and footprint compatibility remain identical.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN classification (EAR99). Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: What does "Not For New Designs" status mean for the Renesas part?

A: This status indicates the part is available for existing production and maintenance applications but is not recommended for new product development. For new designs, consultation with component suppliers for current-generation alternatives is advised.

Q: Are the electrical characteristics identical between both parts?

A: Yes. Isolation voltage (2500Vrms), current transfer ratio (200% @ 1mA), output voltage (40V max), output current (90mA), rise/fall time (200µs), and operating temperature range (-55°C to 100°C) are identical across both manufacturers.
