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

Part Overview

The PS2911-1-F3-M-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 electrical isolation specifications, output characteristics, and mechanical form factors while offering improved availability and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2911-1-F3-M-AX is determined by the following critical parameters that must remain constant across all equivalent parts:

Electrical Specifications:

• Voltage isolation rating of 2500Vrms
• Single-channel configuration
• Transistor output topology
• Minimum current transfer ratio of 100% @ 1mA
• Maximum output current of 40mA per channel
• Maximum output voltage of 40V
• Operating temperature range of -55°C to 100°C

Mechanical Specifications:

• 4-SMD package with flat leads (4-Mini-Flat)
• Surface mount mounting type

Compliance Requirements:

• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)

All substitute parts listed maintain these specifications. Variations in packaging format (Strip, Cut Tape & Digi-Reel, Tape & Reel) and product lifecycle status do not affect electrical or mechanical compatibility. Current transfer ratio maximum values may exceed the original specification without affecting substitution validity.

Parameter Comparison

Engineering Selection Recommendations

PS2911-1-F3-AX (Renesas Electronics Corporation) is the primary substitute for the discontinued PS2911-1-F3-M-AX. This part maintains identical electrical and mechanical specifications with active product status. The PS2911-1-F3-AX is supplied in Cut Tape & Digi-Reel packaging with 20,100 units in stock, providing superior availability. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

PS2911-1-V-F3-AX (Renesas Electronics Corporation) serves as an alternative substitute with identical specifications. Supplied in Tape & Reel packaging with 4,553 units in stock, this variant maintains active product status and REACH unaffected compliance.

PS2911-1-V-AX (Renesas Electronics Corporation) provides substitution capability with Tape & Reel packaging and 1,428 units in stock. Active product status and REACH unaffected compliance are confirmed.

PS2911-1-AX (Renesas Electronics Corporation) is available as a substitute with Strip packaging and 2,201 units in stock. This part carries "Not For New Designs" product status and REACH affected compliance, limiting its suitability for new applications.

All Renesas substitutes demonstrate higher maximum current transfer ratio (400% @ 1mA) compared to the original CEL part (200% @ 1mA), representing improved performance characteristics within the same electrical envelope.

Frequently Asked Questions (FAQ)

Q: Can PS2911-1-F3-AX directly replace PS2911-1-F3-M-AX in existing designs?

A: Yes. Both parts share identical electrical specifications (2500Vrms isolation, 1 channel, 40mA output, 40V maximum), timing characteristics, and 4-SMD flat lead package. Surface mount assembly compatibility is maintained.

Q: What is the difference between the Renesas substitute part numbers?

A: The part numbers indicate packaging format variations. PS2911-1-F3-AX uses Cut Tape & Digi-Reel packaging. PS2911-1-V-AX and PS2911-1-V-F3-AX use Tape & Reel packaging. All maintain identical electrical and mechanical specifications. Selection depends on procurement and assembly requirements.

Q: Why do substitute parts show higher current transfer ratio maximum values?

A: The Renesas variants specify a maximum current transfer ratio of 400% @ 1mA compared to the CEL original at 200% @ 1mA. This represents improved device performance within the same package and does not affect substitution compatibility. Minimum specifications remain constant at 100% @ 1mA.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitutes are ROHS3 compliant. The PS2911-1-AX carries REACH affected status, while PS2911-1-F3-AX, PS2911-1-V-AX, and PS2911-1-V-F3-AX are REACH unaffected.

Q: What is the product lifecycle status of available substitutes?

A: PS2911-1-F3-AX, PS2911-1-V-AX, and PS2911-1-V-F3-AX carry active product status. PS2911-1-AX is designated "Not For New Designs." For new applications, selection from the active status parts is recommended.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Strip, Cut Tape & Digi-Reel, Tape & Reel) affects procurement and assembly logistics only. All variants maintain identical electrical specifications, isolation voltage, output characteristics, and operating temperature range.

Q: Can these parts be used in high-temperature applications?

A: All parts operate across the -55°C to 100°C temperature range. Applications requiring operation beyond 100°C require alternative component selection.
