PS2933-1-V-F3-AX Optoisolator Equivalent and Substitute Parts

Part Overview

The PS2933-1-V-F3-AX is a 2500Vrms isolated optoisolator with Darlington output configuration, designed for single-channel isolation applications in surface mount 4-Mini-Flat packages. The main part (CEL manufacturer) is currently discontinued at DiGi Electronics, necessitating identification of active substitute components that maintain identical electrical and mechanical specifications for seamless integration in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the PS2933-1-V-F3-AX are determined by strict equivalence across all critical electrical and mechanical parameters. The primary substitution criteria are:

• Isolation voltage of 2500Vrms
• Single-channel Darlington output configuration
• Current transfer ratio range of 400% to 4500% @ 1mA
• Maximum output voltage of 350V
• Output current capacity of 60mA per channel
• Rise/fall times of 20µs and 5µs respectively
• Vce saturation maximum of 1V
• Operating temperature range of -55°C to 100°C
• 4-SMD, Flat Leads package configuration (4-Mini-Flat)
• Surface mount capability
• RoHS3 compliance
• REACH unaffected status

Two Renesas Electronics Corporation variants maintain complete parametric equivalence to the original component.

Parameter Comparison

Engineering Selection Recommendations

Both Renesas Electronics Corporation variants are active products with full RoHS3 compliance and REACH unaffected status, making them suitable for regulatory requirement satisfaction. The PS2933-1-V-F3-AX (Renesas variant) provides the highest inventory availability at 7674 units and is packaged in standard Tape & Reel format for production automation. The PS2933-1-V-AX (Renesas variant) is supplied in Strip packaging and offers an alternative with 2771 units available. Both variants maintain identical electrical performance and package geometry to the discontinued CEL original, enabling direct pin-compatible substitution in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Are the Renesas variants drop-in replacements for the discontinued CEL part? A: Yes. Both Renesas variants maintain identical electrical specifications, isolation voltage, output characteristics, temperature range, and 4-Mini-Flat surface mount package configuration. Pinout and footprint compatibility allows direct substitution without PCB modification.

Q: What is the difference between PS2933-1-V-AX and PS2933-1-V-F3-AX? A: The two Renesas variants differ only in packaging format. PS2933-1-V-AX is supplied in Strip format, while PS2933-1-V-F3-AX is supplied in Tape & Reel format. All electrical and mechanical specifications remain identical. Selection depends on production volume and automation requirements.

Q: Can I substitute the Renesas parts in high-volume production? A: Yes. Both variants carry ROHS3 compliance and REACH unaffected status. The Tape & Reel packaged variant (PS2933-1-V-F3-AX) is optimized for automated pick-and-place assembly and offers substantially higher inventory levels (7674 units).

Q: What are the critical parameters for successful substitution? A: Successful substitution requires matching isolation voltage (2500Vrms), channel count (1), output type (Darlington), transfer ratio range (400%-4500%), output voltage/current ratings (350V max, 60mA), and package configuration (4-Mini-Flat surface mount). All substitute parts meet these criteria without deviation.

Q: Are temperature operating ranges identical across all variants? A: Yes. All three parts operate across the identical temperature range of -55°C to 100°C, ensuring thermal compatibility in the same application environment.
