PS2915-1-F3 Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2915-1-F3 is an optoisolator with transistor output rated for 2500Vrms isolation voltage in a 4-SMD flat lead package. This component provides galvanic isolation for AC and DC input signals with a maximum output voltage of 40V and 40mA per channel. The main part (PS2915-1-F3) manufactured by CEL is obsolete, necessitating transition to active equivalent alternatives. Substitute parts maintain identical electrical and mechanical specifications while offering continued manufacturing support and improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Three equivalent parts are identified as substitutes for PS2915-1-F3. The substitution logic is based on strict electrical and mechanical parameter matching:

Critical Parameters for Substitution:

• Isolation Voltage: 2500Vrms
• Number of Channels: 1
• Current Transfer Ratio: 100% min / 400% max @ 1mA
• Output Type: Transistor
• Voltage - Output (Max): 40V
• Current - Output / Channel: 40mA
• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 4-Mini-Flat
• Operating Temperature Range: -55°C ~ 100°C

All substitute parts maintain these parameters identically. Differences in packaging format (Tape & Reel versus Strip) and RoHS compliance status do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

PS2915-1-F3-AX (Renesas) is the primary recommended substitute, providing identical electrical specifications with Tape & Reel packaging suitable for automated assembly processes. This part offers ROHS3 compliance and REACH unaffected status, addressing regulatory requirements absent in the original obsolete component.

PS2915-1-V-F3-AX (Renesas) represents an alternative with equivalent specifications and Tape & Reel packaging. The higher available inventory (4535 pcs) may be advantageous for volume applications.

PS2915-1-V-AX (Renesas) offers the same electrical parameters in Strip packaging format. This variant is suitable for applications where individual component handling or lower volume requirements align with strip packaging delivery.

All three Renesas substitutes provide active product status with ongoing manufacturing support, eliminating obsolescence risk associated with the original CEL part. Selection among the three depends on packaging requirements and supply chain preferences rather than electrical or mechanical considerations.

Frequently Asked Questions (FAQ)

Q: Are all listed substitutes electrically interchangeable with PS2915-1-F3? A: Yes. All three Renesas parts maintain identical electrical parameters including isolation voltage, current transfer ratio, output voltage, output current, timing characteristics, and operating temperature range.

Q: What is the difference between PS2915-1-F3-AX, PS2915-1-V-AX, and PS2915-1-V-F3-AX? A: The primary difference is packaging format. PS2915-1-F3-AX and PS2915-1-V-F3-AX are supplied in Tape & Reel format suitable for automated pick-and-place assembly. PS2915-1-V-AX is supplied in Strip format. All three are electrically and mechanically identical.

Q: Why is the original PS2915-1-F3 obsolete? A: The original CEL-manufactured part is designated obsolete. This status typically indicates discontinued production with no ongoing manufacturing support. Substitution to active equivalents ensures long-term component availability.

Q: Does substitution require PCB layout changes? A: No. All substitute parts use the 4-Mini-Flat package with identical pinout and mechanical dimensions. Direct substitution on existing PCBs is supported without layout modification.

Q: What compliance advantages do the Renesas substitutes provide? A: The Renesas parts are ROHS3 compliant and REACH unaffected, compared to the original part which is RoHS non-compliant and REACH affected. These certifications may be required for certain end markets or applications.

Q: Can I use PS2915-1-V-AX if my assembly line requires Tape & Reel packaging? A: No. PS2915-1-V-AX is supplied in Strip format and is not compatible with standard tape-fed assembly equipment. Use PS2915-1-F3-AX or PS2915-1-V-F3-AX for automated assembly processes.
