Substitute Part Grouping Explanation

Substitute parts for the PS2801C-1-F3-K-A are identified based on strict parametric equivalence across the following critical specifications:

Isolation Voltage: 2500Vrms isolation rating is maintained across all substitutes, ensuring equivalent high-voltage isolation performance.

Channel Configuration: Single channel (1 channel) topology is preserved in all alternatives.

Current Transfer Ratio: Both minimum (50% @ 5mA) and maximum (400% @ 5mA) CTR specifications are identical, guaranteeing equivalent optical coupling efficiency.

Output Characteristics: Transistor output type, maximum output voltage (80V), and output current per channel (30mA) are constant across all substitutes.

Switching Performance: Turn-on/turn-off times (10µs, 7µs) and rise/fall times (5µs, 7µs) are identical, ensuring equivalent dynamic response.

Package Compatibility: All substitutes utilize 4-SOIC (0.173", 4.40mm Width) surface mount package with 4-SSOP supplier device package designation, enabling direct PCB footprint compatibility.

Operating Temperature: -55°C ~ 100°C temperature range is maintained across all alternatives.

The two identified substitutes differ from the main part in product status (active vs. obsolete) and manufacturer designation, but maintain complete electrical and mechanical equivalence.

Engineering Selection Recommendations

PS2801C-1-V-F3-A (Renesas Electronics Corporation): This substitute is classified as active product status with ROHS3 compliance and REACH unaffected designation. Tape & Reel packaging is available. This part is suitable for new designs and ongoing production requiring regulatory compliance assurance.

PS2801C-1Y-F3-A (Renesas Electronics Corporation): This substitute is classified as active product status with ROHS3 compliance and REACH unaffected designation. Tape & Reel packaging is available. This part is suitable for new designs and ongoing production requiring regulatory compliance assurance.

Both Renesas substitutes provide superior compliance posture compared to the obsolete CEL original part. Selection between PS2801C-1-V-F3-A and PS2801C-1Y-F3-A is determined by packaging requirements and supplier availability, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can PS2801C-1-V-F3-A or PS2801C-1Y-F3-A be used as direct replacements for PS2801C-1-F3-K-A?

A: Yes. Both Renesas substitutes maintain identical electrical specifications including 2500Vrms isolation voltage, single channel configuration, 50-400% current transfer ratio, 80V maximum output voltage, 30mA output current, and switching times. Package and mounting type are identical, enabling direct PCB footprint compatibility.

Q: What is the difference between PS2801C-1-V-F3-A and PS2801C-1Y-F3-A?

A: Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications. The difference lies in part number designation only. Both are active products with ROHS3 compliance and REACH unaffected status. Selection should be based on supplier availability and packaging requirements.

Q: Why is the original PS2801C-1-F3-K-A classified as obsolete?

A: The original part is designated obsolete by the manufacturer. Renesas Electronics Corporation substitutes are active products, ensuring long-term availability and continued manufacturing support.

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The original PS2801C-1-F3-K-A is REACH Affected, while both Renesas substitutes (PS2801C-1-V-F3-A and PS2801C-1Y-F3-A) are REACH Unaffected. Both substitutes are ROHS3 Compliant. These differences favor the use of Renesas substitutes for applications requiring regulatory compliance documentation.

Q: What packaging options are available for the substitute parts?

A: Both PS2801C-1-V-F3-A and PS2801C-1Y-F3-A are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Is the 4-SOIC package footprint identical across all three parts?

A: Yes. All three parts utilize 4-SOIC (0.173", 4.40mm Width) surface mount package with 4-SSOP supplier device package designation, ensuring identical PCB footprint compatibility.
