Substitute Part Grouping Explanation

Substitute part groupings for the KMS15-5 are determined strictly by matching the following parameters: same manufacturer, enclosure style, mounting type, power rating, maximum output current, input voltage range, output number, package dimensions, and certification status. All substitutes must also share the required medical application standards and RoHS/REACH compliance, ensuring equivalent mechanical and regulatory compatibility. Output voltage may differ according to application requirements but all other technical and compliance parameters are preserved.

Parameter Comparison

Engineering Selection Recommendations

Component selection for AC/DC converters in medical and regulated applications must prioritize continued product availability, RoHS compliance, REACH status, and adherence to relevant safety standards such as IEC 60601-1, IEC 60950-1, and IEC 62368-1. Substitute parts listed here satisfy the required regulatory certifications and have matching electrical and mechanical parameters, except for output voltage.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting the KMS15-5 in a design?
A1: The main criteria are matching mechanical dimensions, output current capability, power rating, approval agency compliance, operating temperature range, mounting style, and certification status. Output voltage must be reviewed based on circuit requirements.

Q2: Are the KMS15-5 and KMS15-3P3 interchangeable in all designs?
A2: KMS15-5 and KMS15-3P3 are equivalent in form factor, current, power, and compliance parameters. The difference is only in the output voltage (5V vs 3.3V).

Q3: Do the substitute models require redesign of the PCB footprint?
A3: Both models use the same package (9-DIP Module, 4 Leads) and have identical physical dimensions, so no change to the PCB footprint is required.

Q4: Is there any difference in regulatory compliance between the main and substitute parts?
A4: Both KMS15-5 and KMS15-3P3 are certified to CE, EN, IEC, UL standards and meet the same standard numbers (60601-1, 60950-1, 62368-1). Both are RoHS compliant and REACH unaffected.
