Parameter Comparison

Engineering Selection Recommendations

PS2806-4-A (Renesas, Strip Packaging): This direct manufacturer equivalent from Renesas maintains full electrical compatibility with the original PS2806-4-F3-A. The component is classified as Not For New Designs but remains available. Strip packaging suits replacement scenarios for existing inventory or production runs. REACH Affected status requires compliance verification in applications subject to REACH regulations.

PS2806-4-F3-A (Renesas, Tape & Reel Packaging): This parametric equivalent from Renesas offers identical electrical specifications in Tape & Reel packaging, suitable for automated assembly processes. REACH Unaffected status aligns with the original part's regulatory profile. The Not For New Designs status indicates the component family is mature and stable. ROHS3 compliance confirms environmental regulatory adherence.

Both Renesas substitutes provide complete electrical and mechanical interchangeability within the constraints of packaging format and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary reason substitutes are needed for PS2806-4-F3-A? A: The original PS2806-4-F3-A from CEL is discontinued at DiGi Electronics, requiring identification of equivalent parts from alternative manufacturers to ensure supply continuity.

Q: Are the Renesas substitutes functionally identical to the original CEL part? A: Yes. Both Renesas alternatives maintain identical electrical parameters including isolation voltage (2500Vrms), channel count (4), output type (Darlington), and operating temperature range (-55°C to 100°C).

Q: What is the difference between PS2806-4-A and PS2806-4-F3-A from Renesas? A: The primary differences are packaging format (Strip versus Tape & Reel) and REACH regulatory status (Affected versus Unaffected). Electrical specifications are identical.

Q: Which substitute should I select for new production? A: Selection depends on assembly method and regulatory requirements. Use PS2806-4-F3-A (Tape & Reel) for automated pick-and-place assembly. Both parts carry Not For New Designs status, indicating the NEPOC series is not recommended for new designs but available for legacy support.

Q: Are there package compatibility concerns when substituting? A: Both substitutes use the same 16-SOIC surface mount package with identical dimensions (0.173", 4.40mm Width). Mechanical PCB compatibility is assured.

Q: What REACH and RoHS compliance should I expect? A: All three parts are ROHS3 compliant. For REACH-regulated applications, the PS2806-4-F3-A (Renesas, Tape & Reel) maintains REACH Unaffected status matching the original part.
