Key Parameters

Substitute Part Grouping Explanation

Substitute parts maintain functional equivalence through matching key parameters: 2500Vrms isolation voltage, four-channel configuration, transistor output topology, identical current transfer ratio specifications, equivalent maximum output voltage and per-channel current ratings, and matching 16-SOIC package dimensions. All substitutes support -55°C to 100°C operating temperature range and surface mount assembly. Grouping distinguishes between product status classifications and packaging formats while ensuring electrical performance equivalence across all listed alternatives.

Parameter Comparison

Engineering Selection Recommendations

PS2805C-4-F3-A serves as the primary substitute for discontinued PS2805C-4-A designs, offering Active product status with the ROHS3 Compliant compliance profile required for current production environments. This part is available in Cut Tape (CT) and Digi-Reel® packaging with 30,400 units in stock, supporting both low-volume prototyping and high-volume manufacturing.

PS2805C-4-V-A and PS2805C-4-V-F3-A represent secondary alternatives with Active status and full ROHS3 compliance. PS2805C-4-V-F3-A offers Tape & Reel packaging optimal for automated assembly, while PS2805C-4-V-A provides Strip packaging for manual or small-batch assembly applications.

The Renesas Electronics Corporation variant PS2805C-4-A (Not For New Designs status) remains electrically equivalent but is not recommended for new design implementations.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between PS2805C-4-A and PS2805C-4-F3-A? A: Both parts are electrically and mechanically identical, offering matching 2500Vrms isolation, four channels, and 16-SOIC package dimensions. The distinction lies in product status and packaging format: PS2805C-4-F3-A carries Active status with 30,400 units in inventory, while the original CEL part is discontinued. PS2805C-4-F3-A ships in Cut Tape (CT) and Digi-Reel® format.

Q: Can PS2805C-4-V-F3-A be used as a direct substitute in PCB assembly? A: Yes. PS2805C-4-V-F3-A maintains all key electrical parameters—2500Vrms isolation, four-channel output, 80V maximum output voltage, and 30mA per-channel current. Both devices use identical 16-SOIC (0.173", 4.40mm width) package dimensions, ensuring footprint compatibility. Tape & Reel packaging supports automated pick-and-place assembly.

Q: What packaging format should I select for manufacturing? A: Selection depends on production volume and assembly method. Cut Tape (CT) & Digi-Reel® (PS2805C-4-F3-A) supports automated reel-fed assembly and prototyping. Strip packaging (PS2805C-4-V-A) accommodates manual placement or low-volume builds. Tape & Reel (TR) format (PS2805C-4-V-F3-A) optimizes high-volume automated production.

Q: Are all substitutes RoHS3 compliant? A: All listed parts maintain RoHS3 Compliant certification and carry Moisture Sensitivity Level 1 (Unlimited) rating, confirming suitability for standard surface mount assembly processes.

Q: Why should new designs avoid the Renesas PS2805C-4-A "Not For New Designs" variant? A: This designation reflects Renesas' recommendation against incorporating this specific variant into new product development. Active alternatives PS2805C-4-F3-A, PS2805C-4-V-A, and PS2805C-4-V-F3-A provide identical performance with ongoing manufacturing support and no end-of-life risk.
