Key Parameters

Substitute Part Grouping Explanation

The three substitute parts (PS2815-4-F3-A, PS2815-4-V-A, PS2815-4-V-F3-A) are qualified substitutes based on complete electrical and mechanical parameter equivalence. All substitute parts maintain the core specifications: 2500Vrms isolation voltage, 4-channel configuration, identical current transfer ratios (100%-400%), 40V maximum output voltage, 40mA per-channel current, 300mV maximum saturation voltage, and 16-SOIC package footprint.

Key Substitution Parameters:

• Voltage - Isolation: 2500Vrms (identical across all parts)
• Number of Channels: 4 (identical)
• Current Transfer Ratio: 100%-400% @ 1mA (identical)
• Package / Case: 16-SOIC (identical)
• Output Type: Transistor (identical)
• Operating Temperature Range: -55°C ~ 100°C (identical)

Differences between substitutes exist only in packaging format (Cut Tape & Digi-Reel, Strip, or Tape & Reel) and minor timing specifications that remain within functional equivalence ranges.

Parameter Comparison

Engineering Selection Recommendations

PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A are direct electrical and mechanical equivalents to the discontinued PS2815-4-L-A. All three substitute parts maintain active product status with manufacturers, ensuring long-term supply chain viability. All parts comply with ROHS3 requirements and hold ECCN EAR99 classification.

Primary selection criteria should consider packaging availability and supply inventory. PS2815-4-V-F3-A offers the highest inventory level (3123 units) in Tape & Reel format, suitable for high-volume automated assembly. PS2815-4-V-A provides 1542 units in Strip packaging. PS2815-4-F3-A provides 1293 units in Cut Tape and Digi-Reel format.

All substitutes are functionally equivalent for applications requiring 2500Vrms isolation with 4-channel transistor output in 16-SOIC surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Are PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A electrically identical to PS2815-4-L-A? A: Yes. All three substitutes match the PS2815-4-L-A across all critical electrical parameters: 2500Vrms isolation voltage, 4-channel configuration, 100%-400% current transfer ratio, 40V maximum output voltage, 40mA per-channel current, and 300mV saturation voltage.

Q: What is the difference between the substitute parts? A: The substitute parts differ only in packaging format. PS2815-4-F3-A uses Cut Tape & Digi-Reel packaging, PS2815-4-V-A uses Strip packaging, and PS2815-4-V-F3-A uses Tape & Reel packaging. Electrical and mechanical specifications are identical.

Q: Can I use these substitutes in a PS2815-4-L-A socket without circuit modification? A: Yes. All substitute parts share the identical 16-SOIC package footprint (0.173", 4.40mm Width) and pin configuration as the PS2815-4-L-A, enabling direct board-level substitution.

Q: Are all substitutes ROHS3 compliant? A: Yes. PS2815-4-F3-A, PS2815-4-V-A, and PS2815-4-V-F3-A all carry ROHS3 Compliant status, meeting environmental and regulatory requirements.

Q: Which substitute should I select for my application? A: Selection should be based on procurement requirements and inventory availability. All three parts are electrically equivalent. Choose based on available packaging format (Cut Tape & Digi-Reel, Strip, or Tape & Reel) that matches your assembly process.
