PS2811-4-V-F3-A Equivalent and Substitute Parts

Part Overview

The PS2811-4-V-F3-A is a 4-channel optoisolator with transistor output, rated for 2500Vrms isolation voltage. This component provides galvanic isolation for DC input signals with transistor-switched outputs, suitable for applications requiring high-voltage isolation in industrial control and signal conditioning circuits. The original part manufactured by CEL is discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitutes from active product lines to maintain design continuity and supply chain stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2811-4-V-F3-A is based on matching the following critical parameters: 4-channel configuration, 2500Vrms isolation voltage, DC input type, transistor output type, 100-400% current transfer ratio range, 40V maximum output voltage, 40mA per-channel output current, and 16-SOIC surface mount package. These parameters define the functional requirements for direct replacement in isolated signal conditioning and gate-drive applications.

Both identified substitutes are Renesas Electronics Corporation variants of the PS2811 base product. They maintain identical electrical performance specifications and packaging, differing only in product status and distribution packaging format. The critical distinction between substitutes is the packaging configuration: Cut Tape (CT) versus Tape & Reel (TR).

Parameter Comparison

Engineering Selection Recommendations

The PS2811-4-F3-A (Renesas, Cut Tape) and PS2811-4-V-F3-A (Renesas, Tape & Reel) are direct parametric equivalents suitable for replacing the discontinued CEL part. Both substitutes maintain identical electrical specifications and 16-SOIC surface mount packaging, ensuring pin-compatible board-level integration without design modification.

Selection between Renesas variants depends on procurement packaging requirements: Cut Tape format accommodates lower-volume or hand-assembly operations, while Tape & Reel format supports automated pick-and-place manufacturing. Both variants carry ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting industrial regulatory requirements.

The Renesas PS2811-4-F3-A offers the highest available inventory at 13700 units, providing superior supply chain security for design transitions. The PS2811-4-V-F3-A (Renesas Tape & Reel variant) maintains inventory of 3215 units, also suitable for volume production schedules.

Frequently Asked Questions (FAQ)

Q: Are the Renesas variants directly compatible with the discontinued CEL PS2811-4-V-F3-A? A: Yes. Both Renesas variants share identical electrical specifications, current transfer ratios, output voltage and current ratings, isolation voltage, operating temperature range, and 16-SOIC surface mount package dimensions. Pin-for-pin compatibility is confirmed across all functional parameters.

Q: What is the difference between the two Renesas substitutes? A: The PS2811-4-F3-A is supplied in Cut Tape (CT) packaging, while the PS2811-4-V-F3-A is supplied in Tape & Reel (TR) packaging. The electrical specifications are identical. Packaging selection depends on manufacturing process requirements: Cut Tape for manual or low-volume assembly, Tape & Reel for automated production lines.

Q: Does substitution require any circuit design changes? A: No. Identical isolation voltage (2500Vrms), output voltage ratings (40V maximum), per-channel current capacity (40mA), and transfer ratio specifications (100-400% @ 1mA) ensure drop-in replacement functionality without circuit modifications.

Q: Are the substitutes compliant with environmental and regulatory standards? A: Yes. Both Renesas variants are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting industrial and consumer electronics manufacturing standards. REACH status is unaffected for both substitutes.

Q: Which substitute should be selected for new production designs? A: The PS2811-4-F3-A (Renesas, Cut Tape) or PS2811-4-V-F3-A (Renesas, Tape & Reel) are both suitable for production qualification. Selection should align with manufacturing process capability: Tape & Reel format is standard for high-volume automated assembly, while Cut Tape accommodates manual placement or lower-volume production.
