• Rise / Fall Time: 3µs, 5µs
• Input Type: AC, DC
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Voltage - Forward (Vf) (Typ): 1.17V
• Current - DC Forward (If) (Max): 80 mA
• Vce Saturation (Max): 300mV
• Operating Temperature: -55°C ~ 100°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.400", 10.16mm)
• Supplier Device Package: 4-DIP

Compliance Criteria:

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

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts—PS2565L1-1-A, PS2565L1-1-V-A, PS2565L1-1Y-A, and PS2565L1-1Y-V-A—are parametrically equivalent to the original PS2565L1-1-V-A and are suitable for direct replacement in circuit designs.

Product Status Consideration: The original PS2565L1-1-V-A is discontinued at DiGi Electronics. All substitute parts are manufactured by Renesas Electronics Corporation and carry Active product status, ensuring long-term availability and supply chain continuity.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original component's environmental and regulatory requirements. All parts carry EAR99 export classification and HTSUS code 8541.49.8000.

REACH Status Variation: PS2565L1-1-A and PS2565L1-1-V-A are REACH Affected, while PS2565L1-1Y-A and PS2565L1-1Y-V-A are REACH Unaffected. Selection between these groups depends on end-application regulatory requirements and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can PS2565L1-1-A be used as a direct replacement for PS2565L1-1-V-A?

A: Yes. PS2565L1-1-A is a parametric equivalent with identical electrical specifications, isolation voltage, current transfer ratio, output characteristics, and 4-DIP package configuration. The primary difference is product status (Active vs. Discontinued) and REACH compliance classification.

Q: What is the difference between PS2565L1-1Y-A and PS2565L1-1-A?

A: Both parts are parametrically equivalent across all electrical and mechanical specifications. The suffix variation (-Y-) indicates a different manufacturing variant or product line designation within the Renesas portfolio. All electrical performance parameters, isolation voltage, current transfer ratio, and package dimensions remain identical.

Q: Are all substitute parts compatible with the original PCB layout?

A: Yes. All substitute parts use the identical 4-DIP (0.400", 10.16mm) through-hole package configuration. Pin-to-pin compatibility is maintained, allowing direct PCB footprint reuse without layout modifications.

Q: Does REACH status affect component functionality?

A: No. REACH status is a regulatory classification related to chemical substance compliance in the European Union. It does not affect electrical performance, isolation voltage, current transfer ratio, or operational characteristics. Selection should be based on end-market regulatory requirements.

Q: What is the significance of the -V- designation in PS2565L1-1-V-A?

A: The -V- suffix indicates a specific product variant within the PS2565L1-1 series. All variants listed maintain identical electrical specifications and are functionally interchangeable for circuit design purposes.

Q: Can these optoisolators be used in both AC and DC input applications?

A: Yes. All substitute parts support both AC and DC input types, as specified in the Input Type parameter. The 5000Vrms isolation voltage rating applies to both input configurations.

Q: What is the maximum operating temperature range for these components?

A: The operating temperature range is -55°C to 100°C for all substitute parts. This range applies to all electrical specifications and performance parameters.

Q: Are there any packaging differences between substitute parts?

A: No. All substitute parts are supplied in 4-DIP through-hole packages with identical mechanical dimensions (0.400", 10.16mm). Packaging format (Tube) is consistent across all Renesas variants.
