PS2811-1-V-F3-A Equivalent & Substitute Parts

Part Overview

The PS2811-1-V-F3-A is a single-channel optoisolator with transistor output, rated for 2500Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits in industrial control, power management, and signal conditioning systems. The main part (CEL manufacturer) is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2811-1-V-F3-A is determined by strict equivalence across the following critical parameters:

Isolation and Electrical Performance:

• Voltage isolation rating: 2500Vrms (mandatory match)
• Current transfer ratio range: 100% to 400% @ 1mA (mandatory match)
• Output voltage and current ratings: 40V maximum, 40mA per channel (mandatory match)
• Transistor output saturation voltage: 300mV maximum (mandatory match)

Functional Characteristics:

• Single channel configuration (mandatory match)
• DC input type (mandatory match)
• Transistor output topology (mandatory match)
• Rise and fall time specifications: 4µs and 5µs (mandatory match)

Physical and Environmental Compatibility:

• Surface mount technology (mandatory match)
• 4-SOIC package footprint: 0.173" width, 4.40mm (mandatory match)
• Operating temperature range: -55°C to 100°C (mandatory match)
• RoHS3 compliance (mandatory match)
• MSL Level 1 (mandatory match)

Substitute parts must satisfy all parameters listed above without exception. Packaging format (Strip vs. Tape & Reel) and product status (Active vs. Discontinued) do not affect functional equivalence but influence procurement availability.

Parameter Comparison

Engineering Selection Recommendations

Both Renesas Electronics Corporation substitutes—PS2811-1-V-A and PS2811-1-V-F3-A—are parametrically equivalent to the discontinued CEL PS2811-1-V-F3-A. Selection between the two Renesas options is based on procurement requirements:

PS2811-1-V-F3-A (Renesas, Tape & Reel): This part maintains identical part number designation to the original CEL component and is supplied in Tape & Reel packaging. It carries Active product status with 7947 pieces in stock, providing the highest inventory availability. This option is suitable for high-volume production runs and automated assembly processes.

PS2811-1-V-A (Renesas, Strip): This variant is supplied in Strip packaging format and maintains Active product status with 2310 pieces in stock. It is suitable for lower-volume applications or manual assembly environments where Tape & Reel format is not required.

Both substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000, matching the regulatory and compliance profile of the original part. The choice between packaging formats does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PS2811-1-V-A replace PS2811-1-V-F3-A in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications, including isolation voltage (2500Vrms), current transfer ratio (100–400% @ 1mA), output ratings (40V, 40mA), and package footprint (4-SOIC, 0.173" width). The primary difference is packaging format: Strip versus Tape & Reel. Functional performance in the circuit is identical.

Q: What is the difference between Strip and Tape & Reel packaging?

A: Strip packaging is used for manual handling and lower-volume assembly. Tape & Reel packaging is wound on continuous tape for automated pick-and-place assembly systems. Both formats contain the same component with identical electrical specifications. Selection depends on manufacturing process requirements, not circuit performance.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 4-SOIC package with 0.173" (4.40mm) width and 4-SSOP supplier device package designation. PCB footprints and pinout are identical, enabling direct substitution without layout modifications.

Q: Why is the CEL PS2811-1-V-F3-A discontinued?

A: Product discontinuation is a manufacturer decision unrelated to component performance or reliability. Renesas Electronics Corporation continues to manufacture equivalent parts under the same base product number (PS2811) with identical specifications.

Q: Do the Renesas substitutes meet the same compliance standards?

A: Yes. Both Renesas parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications as the original CEL part. Moisture sensitivity level is MSL 1 (Unlimited) for all three variants.

Q: Which Renesas substitute should I select for new designs?

A: For new designs, either Renesas substitute is acceptable. PS2811-1-V-F3-A (Tape & Reel) is recommended for production volumes requiring automated assembly. PS2811-1-V-A (Strip) is suitable for prototyping, low-volume production, or manual assembly. Both are Active products with adequate inventory.

Q: Are there any timing differences between the substitutes?

A: Rise and fall times are identical (4µs and 5µs) across all three parts. Turn-on/turn-off time data is not provided for the CEL part; Renesas PS2811-1-V-A specifies 7µs and 5µs. This specification difference does not affect functional equivalence for standard isolation applications.
