PS2911-1-M-AX Equivalent & Substitute Parts

Part Overview

The PS2911-1-M-AX is a 2500Vrms optoisolator with transistor output, single channel configuration, and 4-SMD flat lead packaging. Manufactured by CEL, this component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. The part operates across -55°C to 100°C and delivers 40mA output current with 300mV maximum saturation voltage, suitable for galvanic isolation applications requiring high voltage isolation ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. All substitute parts maintain identical isolation voltage (2500Vrms), single-channel configuration, transistor output topology, maximum output voltage (40V), output current (40mA), saturation voltage (300mV), operating temperature range (-55°C to 100°C), and 4-SMD flat lead package format.

The substitute parts are grouped into two categories based on Current Transfer Ratio specifications:

Direct Substitutes (CTR Max 400% @ 1mA): PS2911-1-AX, PS2911-1-F3-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX. These parts exceed the main part's CTR maximum of 200%, providing enhanced current transfer performance while maintaining all other electrical and mechanical parameters.

Parametric Equivalent (CTR Max 200% @ 1mA): PS2911-1-M-AX (Renesas Electronics Corporation). This part matches the main part's Current Transfer Ratio specification exactly, differing only in manufacturer designation and product status classification.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: PS2911-1-F3-AX and PS2911-1-V-F3-AX are the primary recommended substitutes. Both parts carry Active product status, ensuring long-term availability and supply chain continuity. PS2911-1-F3-AX is available in Cut Tape and Digi-Reel packaging formats with 20,100 units in stock. PS2911-1-V-F3-AX is available in Tape & Reel format with 4,553 units in stock. Both maintain ROHS3 compliance and REACH Unaffected status.

For Existing Inventory Replacement: PS2911-1-V-AX provides an Active status alternative with 1,428 units available in Tape & Reel packaging. This part maintains identical electrical specifications to the direct substitutes while offering immediate availability.

For Parametric Matching: PS2911-1-M-AX (Renesas Electronics Corporation) provides exact Current Transfer Ratio matching (200% @ 1mA) to the original CEL part. This part carries Active product status with 2,189 units in stock and is available in Strip packaging. This option is suitable when CTR specification tolerance is critical to circuit performance.

Packaging Considerations: Selection between substitute parts should account for manufacturing process requirements. Cut Tape format (PS2911-1-F3-AX) suits automated pick-and-place operations. Tape & Reel format (PS2911-1-V-AX, PS2911-1-V-F3-AX) accommodates high-volume production. Strip packaging (PS2911-1-AX, PS2911-1-M-AX Renesas) supports lower-volume or manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PS2911-1-F3-AX directly replace the discontinued PS2911-1-M-AX (CEL)?

A: Yes. PS2911-1-F3-AX maintains all critical electrical parameters: 2500Vrms isolation voltage, single-channel transistor output, 40mA output current, 300mV maximum saturation voltage, and -55°C to 100°C operating temperature range. The 4-SMD flat lead package is mechanically identical. The higher Current Transfer Ratio (400% vs. 200% maximum) represents enhanced performance within the same functional specification.

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

A: Both parts are manufactured by Renesas Electronics Corporation with identical electrical specifications. The primary difference is packaging format: PS2911-1-V-AX is supplied in standard Tape & Reel format, while PS2911-1-V-F3-AX is supplied in Tape & Reel with Digi-Reel designation. Both carry Active product status and ROHS3 compliance.

Q: Why do some substitute parts have higher Current Transfer Ratio (400%) than the original (200%)?

A: Current Transfer Ratio represents the ratio of output current to input current. A higher CTR maximum indicates the part can deliver greater output current for the same input current. Parts with 400% CTR are functionally compatible with applications designed for 200% CTR, as they meet or exceed the original specification. Circuit design should verify that higher CTR does not introduce unintended performance changes in specific applications.

Q: Is the PS2911-1-M-AX (Renesas) identical to PS2911-1-M-AX (CEL)?

A: Both parts share identical part numbering and electrical specifications, including 200% maximum Current Transfer Ratio. The Renesas version carries Active product status, ensuring continued availability, while the CEL version is discontinued. The Renesas part is the direct manufacturer equivalent and is suitable for direct substitution.

Q: What packaging format should I select for my application?

A: Cut Tape (PS2911-1-F3-AX) is optimized for automated assembly with pick-and-place equipment. Tape & Reel (PS2911-1-V-AX, PS2911-1-V-F3-AX) accommodates high-volume production runs. Strip packaging (PS2911-1-AX, PS2911-1-M-AX Renesas) supports manual assembly or lower-volume applications. All formats contain identical components; selection depends on manufacturing process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant certification. PS2911-1-F3-AX, PS2911-1-V-AX, and PS2911-1-V-F3-AX also carry REACH Unaffected status. PS2911-1-AX carries REACH Affected status. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the inventory status for each substitute part?

A: PS2911-1-F3-AX: 20,100 units in stock. PS2911-1-V-F3-AX: 4,553 units in stock. PS2911-1-M-AX (Renesas): 2,189 units in stock. PS2911-1-V-AX: 1,428 units in stock. PS2911-1-AX: 2,201 units in stock. All parts are listed as New Original In Stock.
