PS2811-4-F3-A Equivalent & Substitute Parts

Part Overview

The PS2811-4-F3-A is a 4-channel optoisolator with transistor output, rated for 2500Vrms isolation voltage. Manufactured by CEL, this component is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives. The part operates across a temperature range of -55°C to 100°C and is housed in a 16-SOIC surface mount package. Due to its discontinued status, equivalent parts from active manufacturers are required for ongoing design support and procurement.

Engineering Selection Recommendations

Primary Substitute: PS2811-4-F3-A (Renesas Electronics Corporation)

The Renesas Electronics Corporation PS2811-4-F3-A is the direct parametric equivalent to the discontinued CEL PS2811-4-F3-A. This part maintains active product status and is ROHS3 compliant. The Cut Tape (CT) packaging format is suitable for standard component handling and assembly processes. Inventory availability of 13700 pieces supports production requirements.

Secondary Substitute: PS2811-4-V-F3-A (Renesas Electronics Corporation)

The PS2811-4-V-F3-A is an alternative from Renesas Electronics Corporation with identical electrical and mechanical specifications. This part is supplied in Tape & Reel (TR) packaging, appropriate for high-volume automated assembly operations. Inventory of 3215 pieces is available. The packaging format difference is the only distinction between this substitute and the primary option.

Both Renesas alternatives are active products with ROHS3 compliance and MSL Level 1 rating, ensuring long-term availability and environmental regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can PS2811-4-F3-A (Renesas) be used as a direct replacement for PS2811-4-F3-A (CEL)?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including isolation voltage (2500Vrms), channel count (4), output type (transistor), and package format (16-SOIC). The Renesas version maintains active product status, making it suitable for direct substitution.

Q: What is the difference between PS2811-4-F3-A and PS2811-4-V-F3-A?

A: The electrical and mechanical specifications are identical. The difference is packaging format: PS2811-4-F3-A is supplied in Cut Tape (CT), while PS2811-4-V-F3-A is supplied in Tape & Reel (TR). Selection depends on assembly process requirements and volume needs.

Q: Are both Renesas substitutes ROHS3 compliant?

A: Yes. Both PS2811-4-F3-A and PS2811-4-V-F3-A from Renesas Electronics Corporation are ROHS3 compliant with MSL Level 1 rating, meeting environmental and moisture sensitivity requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both substitute parts use the 16-SOIC (0.173", 4.40mm Width) package with 16-SSOP supplier device package designation. PCB footprints and assembly processes remain unchanged.

Q: What is the current transfer ratio specification for these optoisolators?

A: The current transfer ratio ranges from 100% (minimum) to 400% (maximum) at 1mA input current. This specification is identical across all three part numbers.

Q: Are there inventory considerations when selecting between the two Renesas substitutes?

A: The PS2811-4-F3-A (Cut Tape) has 13700 pieces in stock, while PS2811-4-V-F3-A (Tape & Reel) has 3215 pieces available. Selection should account for production volume and lead time requirements.
