Substitute Part Grouping Explanation

Equivalent substitutes for the PS2811-4 are identified based on the following critical parameters that define functional interchangeability:

• Number of Channels: 4 channels
• Voltage - Isolation: 2500Vrms
• Current Transfer Ratio: 100% (Min) @ 1mA; 400% (Max) @ 1mA
• Output Type: Transistor output
• Voltage - Output (Max): 40V
• Current - Output / Channel: 40mA
• Rise / Fall Time: 4µs, 5µs
• Operating Temperature Range: -55°C ~ 100°C
• Package / Case: 16-SOIC
• Mounting Type: Surface Mount

The substitute parts PS2811-4-F3-A and PS2811-4-V-F3-A maintain identical electrical specifications and mechanical compatibility with the main part, differing only in packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both PS2811-4-F3-A and PS2811-4-V-F3-A are functionally equivalent to the PS2811-4. The substitutes are manufactured by Renesas Electronics Corporation and carry active product status, ensuring long-term availability and design security.

Compliance Advantages of Substitutes:

• PS2811-4-F3-A and PS2811-4-V-F3-A are both ROHS3 compliant, whereas the original PS2811-4 is RoHS non-compliant
• PS2811-4-F3-A and PS2811-4-V-F3-A are REACH unaffected, whereas the original PS2811-4 is REACH affected

Packaging Selection:

• PS2811-4-F3-A: Cut Tape packaging suitable for component-level handling and lower-volume applications
• PS2811-4-V-F3-A: Tape & Reel packaging optimized for automated assembly and high-volume production

Frequently Asked Questions (FAQ)

Q: Are PS2811-4-F3-A and PS2811-4-V-F3-A electrically interchangeable with the PS2811-4? A: Yes. Both substitutes maintain identical electrical specifications across isolation voltage, channel configuration, current transfer ratio, output voltage, output current, and operating temperature range.

Q: What is the difference between the two substitute parts? A: The primary difference is packaging format. PS2811-4-F3-A is supplied in Cut Tape format, while PS2811-4-V-F3-A is supplied in Tape & Reel format. Both are electrically and mechanically identical. Tape & Reel packaging is standard for high-volume automated assembly processes.

Q: Are there any compatibility concerns with PCB design or assembly? A: No. Both substitute parts use the identical 16-SOIC package with matching pinout and mechanical dimensions (0.173" width, 4.40mm). PCB layouts and assembly processes designed for the PS2811-4 are fully compatible with both substitutes.

Q: Why should the obsolete PS2811-4 be replaced? A: The original PS2811-4 carries obsolete product status, which may limit availability and long-term supply security. The active-status substitutes from Renesas ensure reliable component sourcing and ongoing production support.

Q: Do the substitutes offer compliance advantages? A: Yes. The Renesas substitutes are ROHS3 compliant and REACH unaffected, whereas the original PS2811-4 is RoHS non-compliant and REACH affected. This makes the substitutes preferable for applications requiring regulatory compliance.
