Engineering Selection Recommendations

Selection of substitute parts for the CUI Inc. PSK-S15C-5 should be based on active product status and RoHS compliance. Both CUI Inc. PSK-15D-5 and Recom Power RAC15-05SK maintain active status and ROHS3 compliance, while providing equivalent electrical performance and enclosed through-hole modules. Certification coverage, mounting type, and temperature operation range are aligned with original specifications.

Frequently Asked Questions (FAQ)

What are the critical substitution criteria for PSK-S15C-5?

Substitutes are determined by matching input voltage range, output voltage, output current, power rating, number of outputs, mounting type, package style, operating temperature, and relevant compliance certifications.

Are the substitute parts compatible with the same board layout?

Mechanical compatibility is governed by mounting type and case dimensions. Both PSK-15D-5 and RAC15-05SK use a through-hole DIP package, though users should review the provided size/dimension parameters for direct layout interchangeability.

Do substitute parts maintain comparable compliance and regulatory certifications?

Both substitutes (PSK-15D-5 and RAC15-05SK) are ROHS3 compliant and carry certifications suitable for commercial and household appliance applications.

Is there a difference in efficiency or power handling among the substitute parts?

PSK-15D-5 and RAC15-05SK offer higher maximum output current (3A) and higher efficiency relative to PSK-S15C-5 while maintaining a 5V output. Power rating is also increased (15W vs 14W).
