Parameter Comparison

Engineering Selection Recommendations

All four substitute parts listed are manufactured by Renesas Electronics Corporation and maintain active product status, ensuring continued availability and manufacturing support. The PS2561DL-1Y-A (Renesas version) provides direct part number equivalence to the discontinued CEL original, with identical electrical and mechanical specifications.

The PS2561DL-1Y-V-A variant incorporates an additional voltage rating designation while maintaining all core electrical parameters. This part is actively produced and available in inventory.

The PS2561DL2-1Y-A and PS2561DL2-1Y-V-A variants represent alternative designations within the same product family, with both parts actively manufactured. The PS2561DL2-1Y-A carries REACH Unaffected status, while the PS2561DL2-1Y-V-A also carries REACH Unaffected status. Both maintain full ROHS3 compliance and identical electrical specifications.

Selection between these substitutes should be based on:

1. Direct Replacement Priority: PS2561DL-1Y-A (Renesas) provides exact part number correspondence to the original CEL component.

2. Availability and Inventory: All substitute parts maintain active production status with substantial inventory levels ranging from 1,340 to 9,531 pieces.

3. Regulatory Compliance: All substitutes maintain ROHS3 compliance and MSL Level 1 rating. REACH status varies between affected and unaffected designations; selection should align with end-product regulatory requirements.

4. Packaging: All substitutes are supplied in tube packaging, consistent with standard optoisolator distribution methods.

Frequently Asked Questions (FAQ)

Q: Can PS2561DL-1Y-V-A be used as a direct replacement for PS2561DL-1Y-A?

A: Yes. The PS2561DL-1Y-V-A maintains identical electrical specifications, isolation voltage, output current capacity, and package configuration. The "-V-" designation indicates a voltage rating variant but does not alter the core functional parameters required for substitution.

Q: What is the difference between PS2561DL-1Y-A and PS2561DL2-1Y-A?

A: Both parts maintain identical electrical and mechanical specifications. The PS2561DL2 designation represents an alternative product line variant within the NEPOC series. Both are manufactured by Renesas Electronics Corporation and are functionally interchangeable based on provided parameters.

Q: Are all substitute parts available in the same package configuration?

A: Yes. All substitute parts use 4-SMD surface mount packages with gull wing leads, matching the original PS2561DL-1Y-A package specification. All are supplied in tube packaging.

Q: Does the REACH status difference between PS2561DL-1Y-A and PS2561DL2-1Y-A affect substitution?

A: REACH status is a regulatory compliance designation that does not affect electrical or mechanical compatibility. Selection between REACH Affected and REACH Unaffected variants should be based on end-product regulatory requirements and geographic distribution channels.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the identical temperature range of -55°C to 110°C, matching the original PS2561DL-1Y-A specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), consistent with the original component specifications.

Q: Can these optoisolators be used in applications requiring 5000Vrms isolation?

A: Yes. All substitute parts are rated for 5000Vrms isolation voltage, meeting high-voltage isolation requirements across single-channel DC input applications.

Q: What is the maximum output current for these optoisolators?

A: The maximum output current per channel is 50mA for all substitute parts, with Vce saturation maintained at 300mV maximum.
