Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2911-1-V-F3-AX is determined by conformance to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Voltage - Isolation: 2500Vrms (all substitutes maintain this specification)
• Number of Channels: 1 (single-channel configuration)
• Output Type: Transistor (all substitutes use transistor output)
• Package / Case: 4-SMD, Flat Leads (mechanical compatibility for PCB placement)
• Current Transfer Ratio Range: 100% – 400% @ 1mA (functional operating window)
• Operating Temperature: -55°C ~ 100°C (thermal operating range)

Substitution Categories:

All identified substitutes meet the core electrical and mechanical parameters. The PS2911-1-V-F3-AX differs from its alternatives primarily in packaging format (Tape & Reel) and availability status. Functionally equivalent parts within the PS2911 family share identical isolation voltage, channel count, output characteristics, and thermal specifications. Variations in Current Transfer Ratio minimum (PS2911-1-F3-K-AX specifies 200% minimum versus 100% for others) represent tighter specifications suitable for applications requiring higher guaranteed transfer efficiency.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PS2911-1-V-F3-AX (Renesas, Active Status)

The PS2911-1-V-F3-AX is the preferred substitute for the discontinued main part. This variant carries Active product status and is available in Tape & Reel packaging format. It maintains full electrical equivalence with the original part across all critical specifications including isolation voltage, channel configuration, output characteristics, and operating temperature range. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) align with compliance requirements. Inventory availability of 4553 units in original condition supports procurement objectives.

Secondary Recommendation: PS2911-1-F3-AX (Renesas, Active Status)

The PS2911-1-F3-AX provides an alternative with Active product status and highest available inventory (20,100 units). This part is supplied in Cut Tape and Digi-Reel format. Electrical specifications remain fully equivalent. This option suits high-volume procurement or applications prioritizing availability.

Alternative for Higher Transfer Ratio Requirements: PS2911-1-F3-K-AX (Renesas, Active Status)

The PS2911-1-F3-K-AX specifies a minimum Current Transfer Ratio of 200% @ 1mA, compared to 100% for other variants. This variant is suitable for designs requiring guaranteed higher transfer efficiency across the specified operating range. Product status is Active with 775 units in stock.

Not Recommended: PS2911-1-AX (Not For New Designs Status)

The PS2911-1-AX carries "Not For New Designs" product status. While electrically equivalent, this part should not be selected for new design implementations. The 2201-unit inventory is available but represents an end-of-life product variant.

Frequently Asked Questions (FAQ)

Q: Can I use PS2911-1-F3-AX as a direct replacement for the discontinued PS2911-1-V-F3-AX?

A: Yes. Both parts meet identical electrical specifications across isolation voltage, channel count, output type, and thermal operating range. The substitution is mechanically and electrically valid. The primary difference is packaging format: PS2911-1-V-F3-AX is supplied in Tape & Reel (TR) while PS2911-1-F3-AX uses Cut Tape (CT) and Digi-Reel format. Verify your assembly equipment compatibility with the selected packaging format.

Q: What is the difference between PS2911-1-F3-K-AX and PS2911-1-V-F3-AX?

A: The PS2911-1-F3-K-AX specifies a minimum Current Transfer Ratio of 200% @ 1mA, whereas PS2911-1-V-F3-AX guarantees 100% minimum. All other electrical parameters remain identical. Select PS2911-1-F3-K-AX if your circuit design requires minimum transfer efficiency of 200%. Both are ROHS3 compliant and MSL 1.

Q: Why is the PS2911-1-AX listed as "Not For New Designs"?

A: The PS2911-1-AX carries legacy status and is subject to phase-out. Although the electrical specifications remain equivalent, Renesas designates this variant as unsuitable for new product development. For new designs, select PS2911-1-V-F3-AX, PS2911-1-F3-AX, or PS2911-1-F3-K-AX, all carrying Active product status.

Q: Are all substitutes 4-SMD, Flat Leads format?

A: Yes. All listed substitutes utilize 4-SMD, Flat Leads package configuration with 4-Mini-Flat supplier designation. PCB layout compatibility is maintained across all variants. Packaging format differences (Tape & Reel, Cut Tape, Strip) refer to supplier delivery and assembly handling formats, not component form factor.

Q: Can I interchange PS2911-1-V-F3-AX and PS2911-1-V-AX in production?

A: Yes, from an electrical and mechanical perspective. Both parts specify identical isolation voltage, channel count, output type, and thermal range. PS2911-1-V-AX is supplied in Tape & Reel format identical to PS2911-1-V-F3-AX. Verify inventory status and lead times to confirm procurement feasibility for your production schedule.

Q: Which substitute offers the best availability?

A: PS2911-1-F3-AX provides the highest inventory at 20,100 units. PS2911-1-V-F3-AX offers 4553 units in Active status with Tape & Reel packaging. Both support large-volume procurement. Verify current stock status with your supplier, as inventory levels fluctuate.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. Regulatory compliance is consistent across the PS2911 family variants, supporting applications with environmental and compliance requirements.
