PS2565-1-V-A Equivalent & Substitute Parts

Part Overview

The PS2565-1-V-A is a single-channel optoisolator with transistor output, rated for 5000Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits in industrial control, power management, and signal conditioning systems. The main part (PS2565-1-V-A by CEL) is discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives from Renesas Electronics Corporation that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS2565-1-V-A is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Isolation: 5000Vrms (mandatory)
• Number of Channels: 1 (mandatory)
• Current Transfer Ratio: 80% (Min) @ 5mA and 400% (Max) @ 5mA (mandatory)
• Output Type: Transistor (mandatory)
• Voltage - Output (Max): 80V (mandatory)
• Current - Output / Channel: 50mA (mandatory)
• Vce Saturation (Max): 300mV (mandatory)
• Input Type: AC, DC (mandatory)
• Rise / Fall Time: 3µs, 5µs (mandatory)

Mechanical Equivalence Criteria:

• Package / Case: 4-DIP (0.300", 7.62mm) (mandatory)
• Mounting Type: Through Hole (mandatory)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (mandatory)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory)

All four substitute parts (PS2565-1-A, PS2565-1-V-A by Renesas, PS2565-1Y-A, and PS2565-1Y-V-A) meet these criteria and are therefore direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PS2565-1-V-A (Renesas Electronics Corporation)

This part is the direct equivalent to the discontinued CEL PS2565-1-V-A. It maintains identical electrical and mechanical specifications, identical RoHS3 compliance status, and identical MSL rating. Product status is Active. Inventory availability is 28987 pieces, matching the original part stock level.

Secondary Recommendation: PS2565-1-A (Renesas Electronics Corporation)

This part is a parametric equivalent with identical electrical and mechanical specifications. Product status is Active. Inventory availability is 8800 pieces. The primary difference is packaging format (Tube vs. the original specification), which does not affect electrical performance or mechanical fit in through-hole applications.

Tertiary Recommendations: PS2565-1Y-A and PS2565-1Y-V-A (Renesas Electronics Corporation)

Both parts are parametric equivalents with identical electrical and mechanical specifications and Active product status. PS2565-1Y-A has 1108 pieces in inventory; PS2565-1Y-V-A has 1243 pieces. These parts carry REACH Unaffected status, whereas the primary and secondary recommendations carry REACH Affected status. Selection between these and higher-priority alternatives depends on REACH compliance requirements for the end application.

All four substitute parts are suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametric equivalents with identical electrical specifications (5000Vrms isolation, 1 channel, 80-400% CTR @ 5mA, 50mA output current, 300mV Vce saturation), identical mechanical specifications (4-DIP through-hole package), and identical compliance ratings (ROHS3, MSL 1). The only difference is packaging format (Tube), which does not affect circuit performance or PCB mounting.

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

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is REACH compliance status: PS2565-1-V-A is REACH Affected; PS2565-1Y-V-A is REACH Unaffected. Selection depends on regulatory requirements for the end application. Electrical performance and physical fit are identical.

Q: Are all four substitute parts pin-compatible with the original PS2565-1-V-A?

A: Yes. All substitute parts use the 4-DIP (0.300", 7.62mm) package with identical through-hole mounting specifications. Pin configuration and electrical characteristics are identical across all parts.

Q: Which substitute part has the best inventory availability?

A: PS2565-1-V-A (Renesas) and the original PS2565-1-V-A (CEL) both have 28987 pieces in stock. PS2565-1-A has 8800 pieces. PS2565-1Y-A and PS2565-1Y-V-A have lower inventory levels (1108 and 1243 pieces respectively).

Q: Can I use PS2565-1Y-A instead of PS2565-1-V-A in a REACH-compliant application?

A: Yes, if REACH compliance is a requirement. PS2565-1Y-A is REACH Unaffected, whereas PS2565-1-V-A is REACH Affected. All other electrical and mechanical specifications are identical, making PS2565-1Y-A suitable for applications with REACH restrictions.

Q: What are the critical parameters that determine substitutability?

A: Substitutability is determined by: isolation voltage (5000Vrms), number of channels (1), current transfer ratio (80-400% @ 5mA), output type (Transistor), maximum output voltage (80V), output current (50mA), Vce saturation (300mV), package type (4-DIP through-hole), and compliance ratings (ROHS3, MSL 1). All four substitute parts meet these criteria.
