PS2811-4-F3 Equivalent & Substitute Parts

Part Overview

The PS2811-4-F3 is a 4-channel optoisolator with transistor output, providing 2500Vrms isolation voltage. This component features DC input, transistor output configuration, and is housed in a 16-SOIC surface mount package. The main part (PS2811-4-F3) is obsolete, requiring identification of suitable substitutes from current active product lines. Substitute parts maintain the same electrical and mechanical specifications while offering improved compliance status and availability.

Substitute Part Grouping Explanation

Substitution for the PS2811-4-F3 optoisolator is based on matching the following critical electrical and mechanical parameters: 4-channel configuration, 2500Vrms isolation voltage, 100%-400% current transfer ratio range, DC input with transistor output, 40V maximum output voltage, 40mA per-channel output current, 300mV maximum Vce saturation, and -55°C to 100°C operating temperature range. The package specification (16-SOIC, 0.173" width, 4.40mm) and supplier device package (16-SSOP) must remain identical for direct board-level compatibility.

The identified substitute parts—PS2811-4-F3-A and PS2811-4-V-F3-A—maintain all electrical specifications and mechanical compatibility with the obsolete main part. Differences exist in manufacturer status, packaging format, RoHS compliance, and REACH classification, which are documented in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

Both PS2811-4-F3-A and PS2811-4-V-F3-A are direct functional substitutes for the obsolete PS2811-4-F3 optoisolator. The primary distinction is packaging format: PS2811-4-F3-A is supplied in Cut Tape (CT) format, while PS2811-4-V-F3-A is supplied in Tape & Reel (TR) format. Selection between these should be determined by the volume requirements and material handling specifications of the assembly process.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, representing improved regulatory positioning compared to the non-compliant and REACH-affected main part. All parts maintain the same electrical performance, operating temperature range, isolation voltage, and package dimensions. The optoisolator series designation (NEPOC) and export classification (EAR99) remain consistent across all variants.

Frequently Asked Questions (FAQ)

Q: Are PS2811-4-F3-A and PS2811-4-V-F3-A direct replacements for PS2811-4-F3? A: Yes. Both parts maintain identical electrical specifications (2500Vrms isolation, 4 channels, 100%-400% current transfer ratio, 40V output, 40mA per-channel current) and mechanical compatibility (16-SOIC package, 0.173" width, 16-SSOP supplier package). The primary differences are packaging format (Cut Tape vs. Tape & Reel) and regulatory compliance status.

Q: What is the difference between PS2811-4-F3-A and PS2811-4-V-F3-A? A: The electrical specifications are identical. The packaging differs: PS2811-4-F3-A is supplied in Cut Tape (CT) format with 13,700 units in stock, while PS2811-4-V-F3-A is supplied in Tape & Reel (TR) format with 3,215 units in stock. Selection depends on assembly process requirements and volume needs.

Q: Why is the original PS2811-4-F3 obsolete? A: The main part is classified as obsolete, indicating it has been discontinued by the manufacturer. Substitute parts from Renesas Electronics Corporation (PS2811-4-F3-A and PS2811-4-V-F3-A) provide continued availability with enhanced RoHS3 compliance and REACH Unaffected status.

Q: Does switching to a substitute part require circuit modifications? A: No. The substitute parts maintain identical electrical parameters, operating temperature range (-55°C to 100°C), and physical dimensions. Board layout and circuit design remain unchanged.

Q: What compliance differences should be considered? A: The original PS2811-4-F3 is RoHS non-compliant and REACH Affected. Both substitute parts are ROHS3 Compliant and REACH Unaffected, providing better alignment with current regulatory requirements for electronic component procurement.

Q: Are there inventory considerations in part selection? A: PS2811-4-F3-A (Cut Tape) has higher available inventory (13,700 units) compared to PS2811-4-V-F3-A (Tape & Reel, 3,215 units). For high-volume applications, the Cut Tape variant may offer better availability. Choose based on your supply chain needs and assembly format preference.
