Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS2911-1-L-AX is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Isolation: 2500Vrms
• Number of Channels: 1
• Output Type: Transistor
• Package / Case: 4-SMD, Flat Leads
• Mounting Type: Surface Mount
• Voltage - Output (Max): 40V
• Current - Output / Channel: 40mA
• Operating Temperature Range: -55°C ~ 100°C
• Input Type: DC
• Vce Saturation (Max): 300mV

All four substitute parts (PS2911-1-AX, PS2911-1-F3-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX) manufactured by Renesas Electronics Corporation meet these mandatory electrical and mechanical specifications. Differences exist only in packaging format (Strip, Cut Tape & Digi-Reel, Tape & Reel) and product lifecycle status, which do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

PS2911-1-F3-AX is the primary substitute for PS2911-1-L-AX. This part carries Active product status, indicating ongoing manufacturer support and availability. It is supplied in Cut Tape & Digi-Reel format with 20,100 pieces in stock, providing the highest inventory availability. ROHS3 compliance and REACH Unaffected status confirm regulatory alignment with current environmental standards.

PS2911-1-V-F3-AX is the secondary substitute. This variant maintains Active product status with 4,553 pieces in stock and is supplied in Tape & Reel format. It is suitable for high-volume automated assembly processes. ROHS3 compliance and REACH Unaffected status are confirmed.

PS2911-1-V-AX is an alternative substitute in Tape & Reel packaging with 1,428 pieces in stock and Active product status. ROHS3 compliance and REACH Unaffected status apply.

PS2911-1-AX carries "Not For New Designs" status and should be used only when other substitutes are unavailable. Although functionally equivalent, this product lifecycle designation indicates limited future support. REACH Affected status requires compliance verification for specific applications.

All four substitutes are manufactured by Renesas Electronics Corporation and share the PS2911 base product number, confirming design family equivalence. Selection among active variants should prioritize packaging format compatibility with existing assembly equipment and supply chain requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 2500Vrms isolation voltage, single-channel transistor output, 40V maximum output voltage, 40mA output current, and 4-SMD flat lead package. No circuit modifications are required.

Q: What is the difference between the four substitute parts?

A: The four Renesas substitutes (PS2911-1-AX, PS2911-1-F3-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX) are electrically identical. Differences exist only in packaging format and product lifecycle status. PS2911-1-F3-AX and PS2911-1-V-F3-AX are Active products; PS2911-1-AX is Not For New Designs. Packaging formats are Strip, Cut Tape & Digi-Reel, and Tape & Reel, respectively.

Q: Which substitute should be selected for new production designs?

A: PS2911-1-F3-AX or PS2911-1-V-F3-AX are recommended for new designs. Both carry Active product status and REACH Unaffected compliance. Selection between these two depends on assembly process requirements: Cut Tape & Digi-Reel format for flexible handling, or Tape & Reel format for automated high-volume production.

Q: Are there differences in Current Transfer Ratio between the main part and substitutes?

A: The PS2911-1-L-AX specifies Current Transfer Ratio minimum of 150% at 1mA, while all Renesas substitutes specify 100% minimum at 1mA. Both specifications are within acceptable operating ranges for typical optoisolator applications. Maximum CTR is 300% for the main part and 400% for substitutes, indicating substitutes have broader performance tolerance.

Q: Do all parts meet RoHS and environmental compliance requirements?

A: All five parts are ROHS3 compliant. The main part and three Renesas substitutes (PS2911-1-F3-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX) are REACH Unaffected. PS2911-1-AX is REACH Affected, requiring compliance verification for specific end-use applications.

Q: What is the Moisture Sensitivity Level for these parts?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage conditions apply.

Q: Can PS2911-1-AX be used despite its "Not For New Designs" status?

A: PS2911-1-AX is functionally equivalent and can be used in existing production or repair applications. However, for new design implementations, PS2911-1-F3-AX or PS2911-1-V-F3-AX are preferred due to Active product status and confirmed long-term manufacturer support.
