Substitute Part Grouping Explanation
Substitution logic is based exclusively on matching or exceeding the following parameters, as specified: type (Open Frame), number of outputs (1), input voltage range, output voltage, power rating, form factor (Through Hole, 4-DIP Module), regulatory compliance (CE, CSA, EN, UL, RoHS), and commercial application classification. Substitute parts must not deviate from these critical criteria. Alternative part numbers are drawn only from direct manufacturer references.
Key parameters for substitution:
- Output Voltage (12V)
- Power Rating (≥10W)
- Input Voltage Range (meeting or exceeding 85–264VAC)
- Number of Outputs (1)
- Mounting Type (Through Hole)
- Package / Case (4-DIP Module)
- Approval Agency and Compliance (as listed)
- Line and Load Regulation

Engineering Selection Recommendations
The KPS10-12 is listed as Obsolete. Substitute part numbers KPSA10-12 and KPSB25-12 are both in Active product status with RoHS Compliant designation and hold agency approvals (CE, CSA, UL). Both substitutes match the category (Open Frame AC/DC Converter, Through Hole, 4-DIP Module) and key electrical parameters within the specified ranges for safe and functionally equivalent substitution, per the provided data. Product selection should be based on matching compliance, certification numbers, and regulatory requirements.
Frequently Asked Questions (FAQ)
Q: What parameters must be matched when selecting a substitute for KPS10-12?
A: Output voltage, input voltage range, power rating, number of outputs, mounting type, package/case, regulatory compliance, and form factor.
Q: Are KPSA10-12 and KPSB25-12 identical in size to KPS10-12?
A: Sizes are similar but not identical. KPSA10-12 is slightly smaller, while KPSB25-12 has different dimensions. Mechanical fit should be verified using the dimension specifications provided.
Q: Do the substitute AC/DC converters have the same certification and compliance as the KPS10-12?
A: All listed substitutes are RoHS Compliant, hold CE, CSA, and UL approvals, and comply with the specified standards.
Q: What is the significance of the product status 'Obsolete' for KPS10-12?
A: 'Obsolete' status indicates KPS10-12 is no longer in production, which makes substitution necessary for ongoing designs or support requirements.
Q: How many outputs do the substitute parts provide?
A: Both substitutes provide a single output, matching the KPS10-12.
Q: Do the mounting type and package style match for all alternatives?
A: All parts are designed for Through Hole mounting in a 4-DIP Module case, per provided input.
Q: Is there a difference in input voltage specification?
A: KPSB25-12 has a minimum input voltage of 90VAC compared to 85VAC for KPS10-12 and KPSA10-12.
Q: Are all substitutes RoHS Compliant?
A: Yes, all listed substitutes are RoHS Compliant as specified.
