Parameter Comparison

Engineering Selection Recommendations

PS2561AL2-1-V-F3-L-A is the primary recommended substitute. This part carries Active product status, indicating ongoing manufacturer support and availability. It maintains full parametric equivalence with the PS2501AL-1-F3-A across all electrical and mechanical specifications. REACH Unaffected status aligns with the original part's regulatory profile. This part is suitable for new designs and ongoing production.

PS2561AL-1-A is a secondary substitute option. While parametrically equivalent, this part is classified as Not For New Designs, indicating limited future support. REACH Affected status differs from the original part. This substitute is appropriate only for legacy system maintenance or replacement scenarios where design changes are not feasible.

Both substitute parts are manufactured by Renesas Electronics Corporation and maintain the NEPOC series designation, ensuring design continuity and functional compatibility within existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can PS2561AL2-1-V-F3-L-A be used as a direct replacement for PS2501AL-1-F3-A?

A: Yes. The PS2561AL2-1-V-F3-L-A is parametrically equivalent across all specified electrical parameters, including isolation voltage (5000Vrms), current transfer ratio (50-400% @ 5mA), output characteristics (70V maximum, 30mA per channel), and thermal operating range (-55°C to 100°C). The 4-SMD Gull Wing package is mechanically identical. Active product status provides superior long-term availability.

Q: What is the difference between PS2561AL-1-A and PS2561AL2-1-V-F3-L-A?

A: Both parts are parametrically equivalent. The primary differences are product status (PS2561AL-1-A is Not For New Designs; PS2561AL2-1-V-F3-L-A is Active) and REACH compliance status (PS2561AL-1-A is REACH Affected; PS2561AL2-1-V-F3-L-A is REACH Unaffected). For new applications, PS2561AL2-1-V-F3-L-A is the preferred choice.

Q: Are there packaging differences between these optoisolators?

A: The PS2501AL-1-F3-A and PS2561AL2-1-V-F3-L-A have unspecified packaging formats. The PS2561AL-1-A is supplied in Tube packaging. All three parts use the same 4-SMD Gull Wing case style for surface-mount assembly. Packaging format differences do not affect electrical performance or circuit compatibility.

Q: What compliance certifications apply to these substitutes?

A: All three parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts. The PS2501AL-1-F3-A and PS2561AL2-1-V-F3-L-A are REACH Unaffected. The PS2561AL-1-A is REACH Affected. Regulatory requirements for your application determine which substitute is appropriate.

Q: Can these optoisolators be used interchangeably in existing PCB designs?

A: Yes, within the constraints of product status and regulatory compliance. The identical 4-SMD Gull Wing package, pin configuration, and electrical specifications ensure mechanical and functional interchangeability. Verify that your application's regulatory requirements align with the REACH status of your selected substitute.
