Equivalent & Substitute Parts for PSK-S5B-12 (CUI Inc.)

Part Overview

Manufacturer part number PSK-S5B-12 is an enclosed AC/DC converter from CUI Inc., featuring 1 output at 12V/420mA, a universal input voltage range (85 ~ 264 VAC, 100 ~ 370 VDC), operating temperature range of -40°C to 70°C (with derating), and through-hole mounting in a 26-DIP Module, 5-lead package. The part is marked "Obsolete," necessitating identification of substitute models to maintain compatibility in existing designs and applications. Substitution is essential for continued production and service of systems specifying the PSK-S5B-12.

Substitute Part Grouping Explanation

Substitute parts for PSK-S5B-12 are identified by matching core operational and regulatory criteria. Allowed substitution is strictly based on these parameters: output voltage (12V), maximum output current (~420mA), rated power (5 W), number of outputs (1), input voltage range, product type (enclosed), mounting type (through-hole), package specifications, regulatory approvals, and environmental compliance. Substitute parts must match or exceed these specifications to ensure proper compatibility and performance. Only parts explicitly listed and conforming within these constraints are considered.

Engineering Selection Recommendations

Selection of substitute AC/DC converters for the PSK-S5B-12 should be determined by product status, compliance (including RoHS and REACH), and provided approval agency certifications. PSK-5D-12 and RAC05-12SK/277 are active status models, both ROHS3 compliant, and carry relevant third-party certifications (CE, cURus). Substitutes display compatible electrical parameters, mounting type, and package formats within the category-defined requirements.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met when substituting AC/DC converters in this product category?
A1: All substitutes must match output voltage (12V), power rating (5 W), maximum output current, input voltage range, number of outputs, mounting type, package style, relevant approvals, and RoHS compliance.

Q2: Are the package formats of substitute parts directly interchangeable with the PSK-S5B-12?
A2: Substitute parts have different DIP module lead counts and physical dimensions. Evaluate mechanical fit and pinout arrangement according to project requirements.

Q3: Do the substitute parts offer similar regulatory and environmental compliance?
A3: Substitute parts are ROHS3 compliant and possess third-party certifications (CE, cURus) as specified, supporting application requirements in relevant commercial and household domains.

Q4: Why does product status affect the need for substitution?
A4: PSK-S5B-12 is obsolete; continued procurement and support require alternative models with active production status and equivalent key parameters.
