Substitute Part Grouping Explanation

Substitution eligibility for the PS2911-1-F3-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

  • Current Transfer Ratio (Min): 100% or higher @ 1mA
  • Packaging format (Cut Tape, Digi-Reel, Tape & Reel acceptable for surface mount assembly)
  • Product Status (Active substitutes preferred over Obsolete)

Engineering Selection Recommendations

All four substitute parts are direct parametric equivalents to the PS2911-1-F3-A and are manufactured by Renesas Electronics Corporation under the PS2911 base product number. Selection among these substitutes should be based on the following criteria:

Primary Selection Criteria:

  1. PS2911-1-F3-AX - Recommended for applications requiring maximum inventory availability and flexible packaging options. This part offers Cut Tape and Digi-Reel packaging formats, supporting both manual and automated assembly workflows. ROHS3 compliant and REACH unaffected status ensures regulatory compliance for new designs.

  2. PS2911-1-F3-K-AX - Suitable for applications where higher minimum current transfer ratio (200% @ 1mA) provides design margin. Limited inventory (775 Pcs) restricts this option to lower-volume production runs or design validation phases.

  3. PS2911-1-V-AX - Applicable for tape and reel packaging requirements in high-volume surface mount assembly. Moderate inventory availability (1428 Pcs) supports medium-volume production.

  4. PS2911-1-V-F3-AX - Suitable for tape and reel packaging with F3 filtering designation. Inventory level (4553 Pcs) provides adequate supply for sustained production.

All substitutes carry Active product status, eliminating obsolescence risk associated with the original PS2911-1-F3-A component. ROHS3 compliance and REACH unaffected status across all Renesas alternatives support compliance with current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2911-1-F3-AX be used as a direct replacement for PS2911-1-F3-A in existing designs?

A: Yes. PS2911-1-F3-AX is a parametric equivalent with identical electrical specifications, isolation voltage, output current rating, and operating temperature range. The primary difference is manufacturer (Renesas Electronics vs. CEL) and product status (Active vs. Obsolete). No circuit modifications are required.

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

A: The PS2911-1-F3-K-AX variant specifies a higher minimum current transfer ratio of 200% @ 1mA, compared to 100% @ 1mA for PS2911-1-F3-AX. Both maintain the same maximum ratio of 400% @ 1mA. The K-variant provides tighter specification control for applications requiring higher guaranteed gain.

Q: Are packaging format differences between these substitutes significant?

A: Packaging format differences (Cut Tape, Digi-Reel, Tape & Reel) affect assembly logistics and handling but do not impact electrical performance or PCB-level compatibility. Selection should align with your assembly equipment capabilities and supply chain requirements. All formats are compatible with standard surface mount assembly processes.

Q: Why do the Renesas substitutes show REACH Unaffected status while the original PS2911-1-F3-A shows REACH Affected?

A: REACH status reflects regulatory classification under European chemical regulations. REACH Unaffected status for Renesas parts indicates compliance with current REACH requirements and absence of substances of very high concern (SVHC) at reportable levels. This status is preferable for new designs and ongoing production.

Q: Is the PS2911-1-F3-K-AX suitable for high-volume production?

A: PS2911-1-F3-K-AX inventory (775 Pcs) is limited compared to other substitutes. This part is suitable for design validation, prototype builds, or low-to-medium volume production. For sustained high-volume manufacturing, PS2911-1-F3-AX (20100 Pcs) or PS2911-1-V-F3-AX (4553 Pcs) are recommended.

Q: Do all substitutes maintain the same 4-Mini-Flat package footprint?

A: Yes. All substitute parts use the 4-SMD, Flat Leads package configuration with identical mechanical dimensions and PCB footprint. Direct board-level substitution is supported without layout modifications.

Q: What is the significance of the F3 designation in part numbers?

A: The F3 designation indicates a specific filtering or performance grade within the PS2911 product family. Parts with F3 designation (PS2911-1-F3-AX, PS2911-1-F3-K-AX, PS2911-1-V-F3-AX) share this specification. PS2911-1-V-AX lacks the F3 designation but maintains all other electrical equivalence.
