Engineering Selection Recommendations

Primary Recommendation: PS2805C-4-F3-A (Renesas Electronics Corporation)

The Renesas Electronics Corporation PS2805C-4-F3-A is the optimal substitute for the discontinued CEL PS2805C-4-F3-A. This part maintains identical electrical and mechanical specifications while offering the following advantages:

• Product Status: Active (ongoing manufacturing and support)
• Packaging: Cut Tape (CT) & Digi-Reel® (standard production format)
• Inventory: 30400 Pcs available
• Compliance: ROHS3 Compliant, REACH Unaffected
• Manufacturer: Renesas Electronics Corporation (established semiconductor manufacturer with global support infrastructure)

Secondary Recommendation: PS2805C-4-V-F3-A (Renesas Electronics Corporation)

The PS2805C-4-V-F3-A serves as an alternative substitute with identical electrical specifications:

• Product Status: Active
• Packaging: Tape & Reel (TR) format
• Inventory: 3685 Pcs available
• Compliance: ROHS3 Compliant, REACH Unaffected

Alternative Consideration: PS2805C-4-V-A (Renesas Electronics Corporation)

The PS2805C-4-V-A provides electrical equivalence with different packaging:

• Product Status: Active
• Packaging: Strip format
• Inventory: 1474 Pcs available
• Compliance: ROHS3 Compliant, REACH Unaffected

Not Recommended for New Designs: PS2805C-4-A (Renesas Electronics Corporation)

While electrically equivalent, this part carries a "Not For New Designs" status and should be avoided for new applications.

Frequently Asked Questions (FAQ)

Q1: Can PS2805C-4-F3-A (Renesas) be used as a direct replacement for PS2805C-4-F3-A (CEL)?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The Renesas version maintains the same 4-channel configuration, 2500Vrms isolation rating, 30mA per-channel output, and 16-SSOP package. Pin-to-pin compatibility is confirmed.

Q2: What is the difference between the packaging options (Cut Tape, Strip, and Tape & Reel)?

A: Packaging type affects handling and assembly processes. Cut Tape (CT) & Digi-Reel® is standard for automated pick-and-place assembly. Strip packaging is used for manual assembly or lower-volume applications. Tape & Reel (TR) is standard for high-volume production. All three packaging formats contain electrically identical components.

Q3: Why is PS2805C-4-A marked "Not For New Designs"?

A: This designation indicates the part is in mature/legacy status at the manufacturer. While functionally equivalent, Renesas recommends using active-status alternatives (PS2805C-4-F3-A or PS2805C-4-V-F3-A) for new product development to ensure long-term availability and support.

Q4: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original PS2805C-4-F3-A specifications.

Q5: What is the significance of the "-F3-A" suffix in the part number?

A: The "-F3-A" suffix indicates specific packaging and lead-finish specifications. Parts with this suffix (PS2805C-4-F3-A and PS2805C-4-V-F3-A) are available in standard production formats. The "-V-" designation indicates alternative packaging configurations.

Q6: Can I mix substitute parts from different packaging formats in the same assembly?

A: Yes, provided your assembly process accommodates the specific packaging format. All substitute parts are electrically identical and will function identically in the circuit. Packaging selection should be based on your manufacturing equipment and assembly requirements.

Q7: What is the current transfer ratio specification, and why is it important?

A: The current transfer ratio (50% to 400% @ 5mA) defines the relationship between input LED current and output transistor current. All substitutes maintain this specification, ensuring consistent circuit behavior and signal integrity across all equivalent parts.

Q8: Are there any compliance differences between the CEL original and Renesas substitutes?

A: The original CEL part is REACH Unaffected. Renesas PS2805C-4-A is REACH Affected, while PS2805C-4-F3-A and PS2805C-4-V-F3-A are REACH Unaffected. For applications requiring REACH Unaffected status, select PS2805C-4-F3-A or PS2805C-4-V-F3-A.
