PS2933-1-F3-A Optoisolator: Equivalent & Substitute Parts

Part Overview

The PS2933-1-F3-A is an optoisolator with Darlington output, rated for 2500Vrms isolation voltage, designed for single-channel signal isolation applications. This component is currently in obsolete product status. Alternative models are necessary to maintain supply continuity and ensure long-term design viability for applications requiring galvanic isolation in industrial and power electronics environments.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2933-1-F3-A are qualified based on electrical and mechanical parameter equivalence:

Key Parameters for Substitution:

• Voltage - Isolation: 2500Vrms (all substitutes match)
• Output Type: Darlington (all substitutes match)
• Number of Channels: 1 (all substitutes match)
• Current Transfer Ratio: 400% to 4500% @ 1mA (all substitutes match)
• Voltage - Output (Max): 350V (all substitutes match)
• Current - Output / Channel: 60mA (all substitutes match)
• Package / Case: 4-SMD, Flat Leads (all substitutes match)
• Operating Temperature Range: -55°C to 100°C (all substitutes match)
• Vce Saturation (Max): 1V (all substitutes match)

The three substitute parts—PS2933-1-F3-AX, PS2933-1-V-F3-AX, and PS2933-1-V-AX—are parametrically equivalent to the main part. Differences exist only in packaging format (Tape & Reel versus Strip) and manufacturer certification status (ROHS3 Compliant, REACH Unaffected for substitutes versus REACH Affected for the main part).

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: PS2933-1-F3-AX (Tape & Reel) or PS2933-1-V-F3-AX (Tape & Reel) are recommended substitutes. Both are manufactured by Renesas Electronics Corporation with active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

For Manual Assembly or Low-Volume Applications: PS2933-1-V-AX (Strip packaging) provides an alternative for applications not requiring reel-based automated assembly processes.

Regulatory Compliance: All substitute parts carry ROHS3 compliance and REACH Unaffected status, providing improved compliance position compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can PS2933-1-F3-AX, PS2933-1-V-F3-AX, or PS2933-1-V-AX be used as direct substitutes for PS2933-1-F3-A? A: Yes. All three substitute parts are parametrically equivalent across all critical electrical and mechanical specifications: isolation voltage (2500Vrms), channel count (1), current transfer ratio (400-4500%), output type (Darlington), output voltage (350V maximum), output current (60mA), and package form factor (4-SMD, Flat Leads).

Q: What is the difference between the three substitute parts? A: The primary differences are packaging and manufacturing certification. PS2933-1-F3-AX and PS2933-1-V-F3-AX are supplied in Tape & Reel format, suitable for automated assembly. PS2933-1-V-AX is supplied in Strip format for manual assembly. All three are manufactured by Renesas Electronics Corporation with active product status and ROHS3 compliance.

Q: Why is the main part PS2933-1-F3-A listed as obsolete? A: The PS2933-1-F3-A is identified as an obsolete product. Substitute parts with active product status ensure continued supply availability and long-term design support.

Q: Are there packaging considerations when selecting a substitute? A: Yes. For high-volume automated production, specify PS2933-1-F3-AX or PS2933-1-V-F3-AX (Tape & Reel). For manual assembly or low-volume applications, PS2933-1-V-AX (Strip) is appropriate. All three are compatible with 4-SMD, flat-lead assembly processes.

Q: Do the substitute parts meet current regulatory requirements? A: Yes. All substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in regulated markets.
