Substitute Part Grouping Explanation

All substitute parts within the PS2565 family maintain identical electrical performance specifications: 5000Vrms isolation voltage, 1 channel, 80%-400% current transfer ratio at 5mA, 80V maximum output voltage, and 50mA output current per channel. Substitution is determined by three primary factors:

Electrical Parameters: All listed substitutes maintain the complete electrical specification set of the main part.
Packaging: All parts use 4-SMD, Gull Wing surface mount packages with identical supplier device packaging.
Compliance & Regulatory Status: Parts differ in REACH status (Affected vs. Unaffected) and series designation (NEPOC vs. undesignated).

The following part numbers are parametric equivalents: 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.

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance. Selection between PS2565L-1-K-A and alternatives depends on regulatory requirements and supply availability:

For applications subject to REACH regulations where REACH Affected status is acceptable, PS2565L-1-A, PS2565L-1-V-A, PS2565L2-1-A, and PS2565L2-1-V-A are direct substitutes with higher inventory availability in certain variants.

For applications requiring REACH Unaffected status, PS2565L-1Y-A, PS2565L-1Y-V-A, PS2565L2-1Y-A, and PS2565L2-1Y-V-A are suitable alternatives. PS2565L-1Y-V-A and PS2565L2-1Y-V-A offer the highest inventory levels at 30300 and 3639 units respectively.

All parts maintain identical electrical specifications, operating temperature range, and 4-SMD surface mount packaging, ensuring direct functional interchangeability within the PS2565 optoisolator family.

Frequently Asked Questions (FAQ)

Q: Are all PS2565 variants electrically interchangeable with PS2565L-1-K-A?

A: Yes. All listed substitutes maintain identical isolation voltage (5000Vrms), current transfer ratio (80%-400% @ 5mA), output specifications (80V maximum, 50mA per channel), and operating temperature range (-55°C to 100°C). Electrical performance is equivalent across all variants.

Q: What is the difference between REACH Affected and REACH Unaffected parts?

A: REACH Affected parts contain substances of concern regulated under REACH. REACH Unaffected parts do not contain these substances. Selection depends on your application's regulatory jurisdiction and compliance requirements.

Q: Can I use PS2565L2 variants as substitutes for PS2565L variants?

A: Yes. Both PS2565L and PS2565L2 series maintain identical electrical parameters and 4-SMD packaging. The substitution is based on electrical equivalence and compliance status, not series designation.

Q: Does packaging differ between substitute parts?

A: All parts use 4-SMD, Gull Wing surface mount packages with identical supplier device packaging. No PCB layout modifications are required when substituting between any listed part numbers.

Q: Which substitute offers the best supply availability?

A: PS2565L-1Y-V-A provides the highest inventory at 30300 units, followed by PS2565L2-1Y-V-A at 3639 units. Both are REACH Unaffected and ROHS3 compliant.
