PS2565L-1-K-A Equivalent & Substitute Parts Reference

Part Overview

The PS2565L-1-K-A is a 5000Vrms optoisolator with transistor output in a 4-SMD surface mount package, manufactured by CEL. This part is discontinued at DiGi Electronics. Due to its discontinuation status, equivalent and substitute models from active manufacturers are required for ongoing circuit design and production continuity. The substitute parts listed maintain electrical and mechanical compatibility within the optoisolator category while preserving the critical 5000Vrms isolation voltage rating and transistor output configuration.

Substitute Part Grouping Explanation

Substitution for the PS2565L-1-K-A is categorized into two groups based on electrical and mechanical parameters:

Parametric Equivalents (Direct Replacement Candidates): These parts maintain all critical electrical specifications: 5000Vrms isolation voltage, 1-channel transistor output, 80% minimum and 400% maximum current transfer ratio at 5mA, 80V maximum output voltage, 50mA output current, 300mV Vce saturation, and -55°C to 100°C operating temperature range. All parts are 4-SMD surface mount packages with gull wing leads. All parametric equivalents are manufactured by Renesas Electronics Corporation and maintain active product status.

Functional Substitutes: The LTV-814HS and LTV-814HS-TA1 (Lite-On Inc.) meet the core isolation voltage requirement (5000Vrms) and transistor output configuration but differ in secondary parameters. These parts have lower current transfer ratios (20% minimum, 80% maximum at 100mA), reduced maximum output voltage (35V versus 80V), and higher maximum output current (80mA versus 50mA). Operating temperature range is -30°C to 100°C. Rise and fall times are 4µs and 3µs respectively.

The substitution decision depends on circuit-specific requirements for output voltage swing capability and saturation characteristics.

Engineering Selection Recommendations

Primary Substitutes (Renesas PS2565 Series): The eight Renesas optoisolators—PS2565L-1-A, PS2565L-1-V-A, PS2565L-1Y-A, PS2565L-1Y-V-A, PS2565L2-1-A, PS2565L2-1-V-A, PS2565L2-1Y-A, and PS2565L2-1Y-V-A—are direct parametric equivalents with all electrical specifications matching the PS2565L-1-K-A. All are active products manufactured by Renesas Electronics Corporation with RoHS3 compliance, REACH Affected status, and MSL rating of 1. Selection among these variants depends on packaging preference (Tube) and internal design variations designated by suffix codes. These parts provide production continuity with identical performance envelopes.

Alternative Substitutes (Lite-On LTV-814HS Series): The LTV-814HS and LTV-814HS-TA1 are active substitutes meeting the 5000Vrms isolation requirement. These parts differ in current transfer ratio characteristics, maximum output voltage (35V versus 80V), maximum output current per channel (80mA versus 50mA), and Vce saturation voltage (200mV versus 300mV). The LTV-814HS is packaged in Tube; the LTV-814HS-TA1 is supplied in Tape & Reel format. Both parts are RoHS3 compliant with REACH Unaffected status and MSL rating of 1. Selection of Lite-On parts requires circuit validation for reduced output voltage swing capability.

Frequently Asked Questions (FAQ)

Q: Can all listed parts replace the PS2565L-1-K-A directly? A: The eight Renesas PS2565 variants are direct parametric replacements with identical electrical specifications and 4-SMD gull wing packaging. The Lite-On LTV-814HS series maintains the 5000Vrms isolation voltage and transistor output configuration but with reduced maximum output voltage and modified current transfer characteristics, requiring circuit-level evaluation.

Q: What is the primary difference between Renesas parametric equivalents? A: All eight Renesas parts maintain identical electrical parameters. Differences are in internal design variants designated by model number suffixes (L-1-A, L-1-V-A, L-1Y-A, etc.). Selection is based on design lineage and availability rather than electrical performance divergence.

Q: How do the Lite-On LTV-814HS parts differ from the original part? A: The LTV-814HS and LTV-814HS-TA1 have lower current transfer ratios (20-80% versus 80-400%), reduced maximum output voltage (35V versus 80V), higher maximum output current per channel (80mA versus 50mA), lower Vce saturation (200mV versus 300mV), and narrower operating temperature range (-30°C to 100°C versus -55°C to 100°C).

Q: What is the difference between LTV-814HS and LTV-814HS-TA1? A: Both parts are electrically identical. The primary difference is packaging: LTV-814HS is supplied in Tube, while LTV-814HS-TA1 is supplied in Tape & Reel format for automated assembly.

Q: Are all recommended parts RoHS3 compliant? A: Yes. All Renesas PS2565 variants and Lite-On LTV-814HS series are RoHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the inventory status of active substitutes? A: Renesas parts range from 901 to 30,300 pieces in stock. Lite-On LTV-814HS has 16,958 pieces in stock; LTV-814HS-TA1 has 2,200 pieces in stock. The original PS2565L-1-K-A has 674 pieces available but is discontinued.

Q: Should I select based on REACH compliance status? A: The Renesas PS2565 variants carry REACH Affected status; Lite-On parts carry REACH Unaffected status. Selection may depend on supply chain regulatory requirements and geographic market restrictions.
