PS2911-1-F3-L-AX Equivalent & Substitute Parts

Part Overview

The PS2911-1-F3-L-AX is a 2500Vrms optoisolator with transistor output manufactured by CEL in a 4-SMD flat lead package. This component provides galvanic isolation for single-channel DC input applications with a maximum output current of 40mA per channel. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts maintain identical isolation voltage, output type, package configuration, and electrical performance specifications while offering continued availability and compliance status.

All substitute parts listed maintain identical electrical performance within the specified operating envelope and are pin-compatible with the original PS2911-1-F3-L-AX design.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PS2911-1-F3-AX

The PS2911-1-F3-AX is the preferred substitute for the PS2911-1-F3-L-AX. This part is manufactured by Renesas Electronics Corporation and maintains Active product status, ensuring continued availability and support. It is supplied in Cut Tape (CT) and Digi-Reel® format with 20,100 pieces in stock. The PS2911-1-F3-AX carries ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original part. All electrical parameters, isolation voltage, output configuration, and thermal operating range are identical.

Secondary Recommendation: PS2911-1-V-F3-AX

The PS2911-1-V-F3-AX serves as an alternative substitute with Active product status from Renesas Electronics Corporation. This part is supplied in Tape & Reel (TR) format with 4,553 pieces in stock. It maintains identical electrical specifications and ROHS3 compliance with REACH Unaffected status. Selection of this part is appropriate when Tape & Reel packaging is required for automated assembly processes.

Tertiary Option: PS2911-1-V-AX

The PS2911-1-V-AX is available with Active product status and Tape & Reel (TR) packaging. However, this part carries REACH Affected status, which may impose additional regulatory documentation requirements depending on end-use application and regional compliance obligations. This part is suitable only when REACH Affected status does not conflict with application requirements.

Not Recommended: PS2911-1-AX

The PS2911-1-AX carries Not For New Designs product status, indicating that Renesas Electronics Corporation has designated this part for legacy applications only. While electrically equivalent, this status indicates the manufacturer does not recommend this part for new circuit designs. Use only when existing inventory constraints or legacy system maintenance requirements necessitate this selection.

Frequently Asked Questions (FAQ)

Q: Can PS2911-1-F3-AX be used as a direct replacement for PS2911-1-F3-L-AX?

A: Yes. The PS2911-1-F3-AX is a direct functional equivalent. Both parts share identical isolation voltage (2500Vrms), transistor output configuration, 4-SMD flat lead package, and electrical performance specifications. The primary difference is manufacturer (Renesas Electronics versus CEL) and product status (Active versus Discontinued). Pin configuration and PCB footprint are identical.

Q: What is the difference between the packaging formats (Strip, Cut Tape, Tape & Reel)?

A: Packaging format affects supply and handling but not electrical performance. Strip packaging is for manual handling and small quantities. Cut Tape (CT) and Digi-Reel® format is suitable for semi-automated assembly. Tape & Reel (TR) format is optimized for fully automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements, not circuit functionality.

Q: Why does PS2911-1-AX show "Not For New Designs" status?

A: This designation indicates the manufacturer has transitioned this part to legacy status and recommends against its use in new circuit designs. While the part remains functionally equivalent and available, Renesas Electronics Corporation prioritizes PS2911-1-F3-AX and PS2911-1-V-F3-AX for new applications. Use PS2911-1-AX only for replacement or maintenance of existing systems.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: REACH Unaffected status indicates the part does not contain substances of very high concern (SVHC) listed under EU REACH regulations, requiring no additional compliance documentation. REACH Affected status indicates the part may contain listed substances and requires compliance verification and documentation for EU market distribution. Selection depends on end-use geography and regulatory requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (PS2911-1-AX, PS2911-1-F3-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX) carry ROHS3 compliance certification, matching the original PS2911-1-F3-L-AX. This ensures compatibility with RoHS-regulated markets and applications.

Q: What is the Current Transfer Ratio (CTR) specification, and why does it vary among substitutes?

A: Current Transfer Ratio is the ratio of output collector current to input LED current, expressed as a percentage. The PS2911-1-F3-L-AX specifies 150% to 300% CTR @ 1mA, while substitute parts specify 100% to 400% CTR @ 1mA. The substitute parts have a wider specification range that encompasses the original part's range. Both specifications are acceptable for the same circuit application; the wider range on substitutes indicates manufacturing process capability.

Q: Can I mix different substitute parts in the same production batch?

A: All listed substitute parts are electrically and mechanically equivalent and can be used interchangeably in the same circuit design. However, mixing different packaging formats (Strip, Cut Tape, Tape & Reel) within a single production batch may complicate inventory management and assembly logistics. Standardizing on a single part number per production run is recommended for traceability and supply chain efficiency.

Q: What inventory levels are available for each substitute?

A: PS2911-1-F3-AX: 20,100 pieces in stock (highest availability). PS2911-1-V-F3-AX: 4,553 pieces in stock. PS2911-1-V-AX: 1,428 pieces in stock. PS2911-1-AX: 2,201 pieces in stock. PS2911-1-F3-AX is recommended for applications requiring large production volumes or long-term supply security.
