Substitute Part Grouping Explanation

Substitute parts for the PS2565-1-V are classified into two categories based on parameter alignment:

Direct Manufacturer Equivalents (Identical Electrical Parameters): Parts that maintain all critical electrical specifications including 5000Vrms isolation, 80-400% current transfer ratio at 5mA, 80V maximum output voltage, 50mA output current, and 300mV Vce saturation. These parts are functionally interchangeable at the circuit level.

Parametric Equivalents (Matching Core Isolation & Output Characteristics): Parts that maintain 5000Vrms isolation voltage, single-channel transistor output, 4-DIP package, and operating temperature range, with identical current transfer ratio specifications. These provide equivalent functional performance for the same application requirements.

Similar Parts (Different Electrical Parameters): Parts that share 5000Vrms isolation and 4-DIP package but differ in current transfer ratio specifications, output voltage rating, output current capability, and saturation voltage. These require circuit-level evaluation for compatibility.

Engineering Selection Recommendations

Primary Recommendation: PS2565-1-V-A

The PS2565-1-V-A manufactured by Renesas Electronics Corporation is the direct equivalent replacement for the obsolete PS2565-1-V. This part maintains identical electrical specifications across all critical parameters: 5000Vrms isolation voltage, 80-400% current transfer ratio at 5mA, 80V maximum output voltage, 50mA output current, and 300mV Vce saturation. The PS2565-1-V-A is in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment. Tube packaging is standard for this variant.

Secondary Recommendations: PS2565-1-A and PS2565-1Y-A

Both PS2565-1-A and PS2565-1Y-A from Renesas Electronics provide identical electrical performance to the PS2565-1-V-A. These parts are parametric equivalents with active product status and ROHS3 compliance. Selection between these variants depends on packaging requirements and internal design specifications. All three Renesas variants (PS2565-1-V-A, PS2565-1-A, PS2565-1Y-A) are functionally interchangeable at the circuit level.

Alternative Consideration: PS2565-1Y-V-A

The PS2565-1Y-V-A maintains identical electrical specifications and active production status with ROHS3 compliance. This variant is suitable where specific design documentation references the 1Y designation.

Limited Compatibility: LTV-814HM

The LTV-814HM from Lite-On Inc. shares 5000Vrms isolation and 4-DIP package format but differs in critical electrical parameters. The LTV-814HM specifies 20-80% current transfer ratio at 100mA (versus 80-400% at 5mA), 35V maximum output voltage (versus 80V), 80mA output current (versus 50mA), and 200mV Vce saturation (versus 300mV). The package footprint differs at 0.400" (10.16mm) versus 0.300" (7.62mm). The LTV-814HM is suitable only for applications where the lower output voltage rating and different current transfer ratio characteristics are acceptable. Operating temperature range is -30°C to 100°C versus -55°C to 100°C.

Frequently Asked Questions (FAQ)

Q: Can PS2565-1-V-A be used as a direct replacement for PS2565-1-V?

A: Yes. The PS2565-1-V-A maintains identical electrical specifications including 5000Vrms isolation, 80-400% current transfer ratio at 5mA, 80V output voltage, 50mA output current, and 300mV Vce saturation. The 4-DIP package dimensions are identical at 0.300" (7.62mm). No circuit modifications are required.

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

A: All three parts are manufactured by Renesas Electronics and provide identical electrical performance. The designations reflect internal product line variations. Selection depends on packaging availability and design documentation requirements. All are functionally interchangeable.

Q: Is the LTV-814HM compatible with PS2565-1-V applications?

A: The LTV-814HM is not a direct replacement. While it maintains 5000Vrms isolation, it differs in current transfer ratio (20-80% at 100mA versus 80-400% at 5mA), maximum output voltage (35V versus 80V), output current (80mA versus 50mA), and package dimensions (0.400" versus 0.300"). Circuit-level evaluation is required to determine compatibility for specific applications.

Q: What is the package difference between PS2565-1-V and LTV-814HM?

A: Both use 4-DIP package format, but dimensions differ. PS2565-1-V uses 4-DIP (0.300", 7.62mm) while LTV-814HM uses 4-DIP (0.400", 10.16mm). PCB footprints are not interchangeable without layout modification.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. PS2565-1-V-A, PS2565-1-A, PS2565-1Y-A, and PS2565-1Y-V-A are all ROHS3 compliant. The original PS2565-1-V is RoHS non-compliant. The LTV-814HM is also ROHS3 compliant.

Q: What is the operating temperature range difference between PS2565-1-V and LTV-814HM?

A: PS2565-1-V and all Renesas equivalents operate from -55°C to 100°C. The LTV-814HM operates from -30°C to 100°C, providing a narrower low-temperature range. Applications requiring -55°C operation must use PS2565 series parts.

Q: Can I mix different PS2565 variants in the same design?

A: Yes. PS2565-1-V-A, PS2565-1-A, PS2565-1Y-A, and PS2565-1Y-V-A are electrically identical and can be used interchangeably within the same circuit or across multiple units of the same design.
