Substitute Part Grouping Explanation

Substitute parts for the PS2565L-1-F3-K-A are classified into two categories based on electrical and mechanical compatibility:

Category 1: Parametric Equivalents (Same Electrical Specifications) Renesas Electronics Corporation PS2565L series parts maintain identical electrical parameters as the main part, including isolation voltage (5000Vrms), current transfer ratio (80-400% @ 5mA), maximum output voltage (80V), output current (50mA), forward voltage (1.17V), and saturation voltage (300mV). These parts share identical operating temperature range (-55°C ~ 100°C) and are all ROHS3 compliant with MSL Level 1 rating. All are actively produced by Renesas in Tape & Reel packaging.

Category 2: Functional Substitutes (Equivalent Isolation & Basic Output Characteristics) Lite-On Inc. LTV-814 series parts meet the same 5000Vrms isolation requirement with single-channel transistor output in 4-SMD, Gull Wing packaging. However, these parts have different electrical specifications: lower current transfer ratio (20-80% @ 100mA vs. 80-400% @ 5mA), reduced maximum output voltage (35V vs. 80V), higher maximum output current (80mA vs. 50mA), and lower saturation voltage (200mV vs. 300mV). Operating temperature range is narrower (-30°C ~ 100°C vs. -55°C ~ 100°C). Both variants (tube and tape & reel packaging) are active products from the manufacturer.

Engineering Selection Recommendations

Preferred Substitutes: Renesas PS2565L Series (Active Products)

The Renesas Electronics Corporation PS2565L family provides parametric equivalents with complete electrical compatibility. All variants (PS2565L-1-F3-A, PS2565L-1-V-F3-A, PS2565L-1Y-F3-A, PS2565L-1Y-V-F3-A, PS2565L2-1-F3-A, PS2565L2-1-V-F3-A, PS2565L2-1Y-F3-A) maintain identical isolation voltage, current transfer ratio specifications, output voltage, output current, saturation voltage, and operating temperature range. All are ROHS3 compliant with MSL Level 1 rating and available in Tape & Reel packaging. These parts are actively manufactured and offer the highest inventory availability, making them the direct-replacement option.

Alternative Substitutes: Lite-On LTV-814HS Series (Functional Compatibility)

The Lite-On Inc. LTV-814HS and LTV-814HS-TA1 parts maintain the 5000Vrms isolation voltage and single-channel transistor output in 4-SMD, Gull Wing packaging. However, these parts are functional substitutes with different electrical characteristics. The narrower operating temperature range (-30°C vs. -55°C minimum), different current transfer ratio specification (20-80% @ 100mA vs. 80-400% @ 5mA), reduced maximum output voltage (35V vs. 80V), and lower saturation voltage (200mV vs. 300mV) require circuit re-evaluation. Use these parts only when the circuit design tolerates reduced maximum output voltage and can operate within the -30°C ~ 100°C temperature range.

Frequently Asked Questions (FAQ)

Q: What makes the Renesas PS2565L parts direct substitutes for the PS2565L-1-F3-K-A?

A: The Renesas PS2565L series maintains identical electrical specifications across all critical parameters: 5000Vrms isolation voltage, 80-400% current transfer ratio at 5mA input, 80V maximum output voltage, 50mA output current, 300mV saturation voltage, and -55°C ~ 100°C operating temperature range. All variants are ROHS3 compliant with MSL Level 1. The only differences are part number designations (related to internal configuration options) and packaging format (Tape & Reel vs. bulk).

Q: Can the Lite-On LTV-814HS replace the PS2565L-1-F3-K-A in all applications?

A: The LTV-814HS provides the same isolation voltage and package type but has different electrical characteristics. The maximum output voltage is 35V instead of 80V, output current is higher at 80mA vs. 50mA, saturation voltage is lower at 200mV vs. 300mV, and the operating temperature minimum is -30°C instead of -55°C. Additionally, the current transfer ratio specification is different (20-80% @ 100mA input vs. 80-400% @ 5mA input). Use this part only when your circuit design accommodates these electrical differences and does not require operation below -30°C.

Q: What is the difference between the various Renesas PS2565L part number variants?

A: All Renesas PS2565L variants in the comparison table provide identical electrical performance. The differences in part numbers (such as -1-F3-A vs. -1-V-F3-A vs. -1Y-F3-A vs. -L2 variants) relate to internal configuration options and manufacturing codes. Consult the Renesas datasheet for specific configuration details. From an electrical and mechanical standpoint, these parts are interchangeable for the PS2565L-1-F3-K-A application.

Q: Why is the Renesas part in Tape & Reel packaging when the original is not specified?

A: The PS2565L-1-F3-K-A original packaging type is not specified in the available data. Renesas equivalents are available in Tape & Reel (TR) packaging, which is the standard format for SMD components in automated assembly. Tape & Reel provides the same component functionality as bulk packaging; the difference is only in handling and assembly logistics.

Q: Are all substitutes ROHS3 compliant?

A: Yes. Both the Renesas PS2565L series and Lite-On LTV-814HS series are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts meet current environmental and regulatory standards for electronic component manufacturing.
