PS2911-1-F3 Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2911-1-F3 is a 2500Vrms isolated optoisolator with transistor output, designed for single-channel isolation applications requiring surface mount implementation in 4-SMD flat lead packaging. The original CEL manufacturer part is currently obsolete, necessitating evaluation of active substitute components from Renesas Electronics Corporation that maintain parametric equivalence for circuit replacement purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of PS2911-1-F3 is determined by the following critical parameters: 2500Vrms isolation voltage, single-channel transistor output configuration, 4-SMD flat lead packaging, 40V maximum output voltage, 40mA output current capability, and -55°C to 100°C operating temperature range. The substitute parts listed below maintain these core electrical and mechanical specifications.

Differences among substitute parts are limited to Current Transfer Ratio minimum specifications and packaging formats (Cut Tape, Digi-Reel, or Tape & Reel). All substitutes are manufactured by Renesas Electronics Corporation and carry active product status with RoHS3 compliance and REACH unaffected designations.

Parameter Comparison

Engineering Selection Recommendations

All Renesas Electronics substitute parts (PS2911-1-F3-AX, PS2911-1-F3-K-AX, PS2911-1-V-AX, PS2911-1-V-F3-AX) maintain active product status and carry RoHS3 compliance certification, eliminating compliance risks associated with the obsolete CEL original component. These substitutes are suitable for new circuit board designs and product revisions requiring environmental compliance.

PS2911-1-F3-AX and PS2911-1-V-F3-AX are recommended for direct replacement in existing designs due to identical Current Transfer Ratio specifications (100% - 400% @ 1mA) matching the original part performance range.

PS2911-1-F3-K-AX provides elevated minimum Current Transfer Ratio (200% @ 1mA) and should be selected only when circuit design explicitly requires this tighter specification range.

PS2911-1-V-AX is functionally equivalent with identical transfer ratio specifications and available in Tape & Reel packaging format.

Packaging format differences (Cut Tape, Digi-Reel, or Tape & Reel) do not affect component electrical performance and are determined by manufacturing and procurement requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary reason to substitute PS2911-1-F3? A: The original CEL-manufactured PS2911-1-F3 is obsolete. Renesas Electronics Corporation produces parametrically equivalent active alternatives with identical electrical specifications and improved compliance certifications.

Q: Which substitute part is the closest direct replacement? A: PS2911-1-F3-AX and PS2911-1-V-F3-AX are direct electrical equivalents with identical Current Transfer Ratio specifications. Both are manufactured by Renesas and carry active product status. Selection between them is determined by packaging format requirements: Cut Tape & Digi-Reel for PS2911-1-F3-AX or Tape & Reel for PS2911-1-V-F3-AX.

Q: Why does PS2911-1-F3-K-AX have different Current Transfer Ratio specifications? A: PS2911-1-F3-K-AX specifies a minimum Current Transfer Ratio of 200% @ 1mA compared to 100% for other equivalents. This represents a tighter binned component. It should only be used if circuit design calculations require this specific minimum threshold.

Q: Are all substitute parts compatible with the original 4-SMD, flat lead package? A: Yes. All substitute parts use identical 4-Mini-Flat packaging, ensuring mechanical and footprint compatibility on PCBs designed for PS2911-1-F3.

Q: What compliance improvements do the Renesas substitutes provide? A: All Renesas alternatives carry RoHS3 Compliant certification and REACH Unaffected status, eliminating the RoHS non-compliance designation of the original CEL part. This ensures suitability for applications subject to environmental and regulatory compliance requirements.

Q: Are there performance differences in switching characteristics? A: No. All substitutes maintain identical Turn On / Turn Off Time (40µs, 120µs) and Rise / Fall Time (5µs, 10µs) specifications, ensuring equivalent switching performance in existing circuit designs.

Q: How should packaging format be selected? A: Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) does not affect component performance. Selection is based on assembly process capability: Cut Tape for pick-and-place systems, Digi-Reel for automated dispensing, or Tape & Reel for high-volume board assembly.

Q: Can PS2911-1-V-AX be used as a substitute despite different part number formatting? A: Yes. PS2911-1-V-AX maintains all critical electrical parameters: 2500Vrms isolation, 100-400% Current Transfer Ratio, and identical switching characteristics. The "V" designation in the part number reflects packaging format variation, not functional difference.
