PS2565-1 Equivalent & Substitute Parts

Part Overview

The PS2565-1 is a 5000Vrms isolation optoisolator with transistor output in 4-DIP packaging, manufactured by CEL. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The PS2565-1 operates across AC and DC input types with a single channel configuration, delivering 50mA output current and supporting operating temperatures from -55°C to 100°C. Identification of compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the PS2565-1 are categorized based on electrical parameter compatibility and physical form factor alignment. The primary substitution criteria are:

Direct Manufacturer Equivalents: Parts maintaining identical electrical specifications including 5000Vrms isolation, 80-400% current transfer ratio at 5mA, 80V maximum output voltage, 300mV Vce saturation, and -55°C to 100°C operating range. These parts are pin-compatible and functionally interchangeable.

Parametric Equivalents: Parts with matching isolation voltage, channel count, output type, and package form factor but originating from the same manufacturer (Renesas Electronics Corporation). These maintain the NEPOC series designation and identical electrical performance characteristics.

Similar Alternatives: Parts meeting 5000Vrms isolation and 4-DIP package requirements but with different electrical specifications. These include variations in current transfer ratio measurement conditions, output voltage limits, saturation voltage, and operating temperature ranges. Substitution requires circuit-level verification.

Engineering Selection Recommendations

Direct Replacement (Preferred): PS2565-1-A, PS2565-1-V-A, PS2565-1Y-A, and PS2565-1Y-V-A are manufactured by Renesas Electronics Corporation and maintain identical electrical specifications to the PS2565-1. All four parts are active products with ROHS3 compliance, providing regulatory advantage over the obsolete CEL original. These parts are suitable for direct substitution without circuit modification.

Alternative Selection with Parameter Verification: HCPL-814-000E (Broadcom Limited) and LTV-814 (Lite-On Inc.) meet the 5000Vrms isolation requirement and 4-DIP package specification. However, these parts operate with different current transfer ratio measurement conditions (20-300% @ 1mA versus 80-400% @ 5mA), reduced maximum output voltage (35V versus 80V), and lower operating temperature minimum (-30°C versus -55°C). Circuit-level analysis is required to confirm compatibility with specific application requirements.

Limited Compatibility: LTV-814HM differs significantly in output current capability (80mA versus 50mA) and current transfer ratio measurement conditions (20-80% @ 100mA). This variant is suitable only for applications with modified output current requirements.

Compliance Consideration: All active substitute parts carry ROHS3 compliance certification, whereas the original PS2565-1 is RoHS non-compliant. This compliance status supports long-term design sustainability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can PS2565-1-A directly replace PS2565-1 without circuit modification?

A: Yes. PS2565-1-A maintains identical electrical specifications including 5000Vrms isolation, 80-400% current transfer ratio at 5mA, 80V maximum output voltage, 300mV Vce saturation, and -55°C to 100°C operating temperature. Pin configuration and 4-DIP package dimensions are identical. Direct substitution is supported.

Q: What are the key differences between PS2565-1 and HCPL-814-000E?

A: Both parts provide 5000Vrms isolation in 4-DIP packaging. Differences include: current transfer ratio measured at 1mA (20-300%) versus 5mA (80-400%), maximum output voltage of 35V versus 80V, Vce saturation of 200mV versus 300mV, and operating temperature range of -30°C to 100°C versus -55°C to 100°C. Applications requiring the full -55°C lower temperature limit or 80V output voltage cannot use HCPL-814-000E.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (PS2565-1-A, PS2565-1-V-A, PS2565-1Y-A, PS2565-1Y-V-A, HCPL-814-000E, LTV-814, LTV-814HM) carry ROHS3 compliance certification. The original PS2565-1 is RoHS non-compliant.

Q: What is the difference between PS2565-1Y-A and PS2565-1-A?

A: Both parts are manufactured by Renesas Electronics Corporation with identical electrical specifications. The primary difference is the series designation: PS2565-1-A belongs to the NEPOC series, while PS2565-1Y-A does not specify a series designation. Electrical performance and pin compatibility are equivalent.

Q: Can LTV-814HM be used in place of PS2565-1?

A: LTV-814HM is not a direct substitute. While it maintains 5000Vrms isolation and 4-DIP packaging, it differs in output current (80mA versus 50mA), current transfer ratio measurement conditions (20-80% @ 100mA versus 80-400% @ 5mA), and operating temperature range (-30°C to 100°C versus -55°C to 100°C). Use only if circuit design accommodates these parameter variations.

Q: What packaging options are available for PS2565-1 substitutes?

A: PS2565-1-A, PS2565-1-V-A, PS2565-1Y-A, and PS2565-1Y-V-A are supplied in Tube packaging. HCPL-814-000E and LTV-814 are supplied in Tube packaging. LTV-814HM packaging is not specified. All maintain 4-DIP (0.300", 7.62mm) form factor except LTV-814HM which uses 4-DIP (0.400", 10.16mm).

Q: Which substitute part has the highest inventory availability?

A: LTV-814 (Lite-On Inc.) has the highest inventory with 57,024 pieces in stock, followed by PS2565-1-V-A (Renesas Electronics) with 28,987 pieces. PS2565-1-A has 8,800 pieces available.
