PS2811-4-V-A Optoisolator - Equivalent & Substitute Parts

Part Overview

The PS2811-4-V-A is a 4-channel optoisolator with transistor output, rated for 2500Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between digital and analog circuits in industrial control, power management, and signal conditioning systems. The PS2811-4-V-A is discontinued at DiGi Electronics, making it necessary to identify equivalent substitute parts that maintain identical electrical and mechanical characteristics for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2811-4-V-A are determined by equivalence across all critical electrical and mechanical parameters. The substitution logic is based strictly on the following criteria:

Electrical Equivalence Requirements:

• Identical number of channels (4)
• Identical isolation voltage rating (2500Vrms)
• Identical output type (Transistor)
• Identical maximum output voltage (40V)
• Identical output current per channel (40mA)
• Identical current transfer ratio range (100% - 400% @ 1mA)
• Identical rise/fall time specifications (4µs, 5µs)
• Identical Vce saturation maximum (300mV)
• Identical operating temperature range (-55°C ~ 100°C)
• Identical input type (DC)

Mechanical Equivalence Requirements:

• Identical package type (16-SOIC)
• Identical mounting type (Surface Mount)
• Identical physical dimensions (0.173", 4.40mm Width)

Compliance Requirements:

• ROHS3 Compliant status

The PS2811-4-F3-A and PS2811-4-V-F3-A variants manufactured by Renesas Electronics Corporation satisfy all electrical and mechanical equivalence criteria and are direct substitutes for the discontinued PS2811-4-V-A.

Parameter Comparison

Engineering Selection Recommendations

Both PS2811-4-F3-A and PS2811-4-V-F3-A are equivalent substitutes for the discontinued PS2811-4-V-A, with the primary difference being packaging format:

PS2811-4-F3-A (Cut Tape Packaging): Suitable for lower-volume applications and prototype development. Offers flexibility for component procurement with 13,700 units in stock.

PS2811-4-V-F3-A (Tape & Reel Packaging): Intended for high-volume production environments. Accommodates automated assembly line requirements with 3,215 units in stock.

Both substitute parts are manufactured by Renesas Electronics Corporation and hold Active product status, ensuring long-term availability and technical support. Both are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between the two variants depends solely on production volume and assembly methodology requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2811-4-F3-A and PS2811-4-V-F3-A be used interchangeably in place of PS2811-4-V-A?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The difference between them is packaging format (Cut Tape versus Tape & Reel), which affects handling and assembly processes but not component performance or board-level functionality.

Q: What is the difference between the packaging options?

A: Cut Tape (CT) packaging provides individual component access and is suitable for manual assembly, prototype builds, and lower-volume applications. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly systems used in high-volume production environments.

Q: Are there any differences in electrical performance between the substitute parts and the original PS2811-4-V-A?

A: No. The PS2811-4-F3-A and PS2811-4-V-F3-A maintain identical electrical specifications including isolation voltage, output current rating, current transfer ratio, switching times, saturation voltage, and operating temperature range.

Q: What is the difference in REACH compliance status?

A: The original PS2811-4-V-A is REACH Affected, while both Renesas substitutes are REACH Unaffected. This reflects manufacturer status and does not affect component performance or suitability for applications. REACH compliance status indicates regulatory classification but does not alter electrical characteristics or functionality.

Q: Can the packaging format be mixed in the same assembly run?

A: Packaging format selection must be determined before assembly begins based on your production equipment capabilities. For consistency and supply chain management, maintaining a single packaging format per production lot is standard engineering practice.
