Substitute Part Grouping Explanation

Substitution is determined based on essential parameters that ensure functional compatibility and regulatory compliance. The substitute group is limited to parts matching the following criteria as provided for the open frame AC/DC converter category:

Number of Outputs: 1
Output Voltage: 24V
Input Voltage Range: Must at least include 85—264 VAC
Output Power: Minimum 15W
Mounting Type: Through Hole
Package / Case: 4-DIP Module
Approval Agency: Must list CE and UL minimum
RoHS Status: RoHS Compliant

Only substitutes that strictly conform to these declared parameters are considered.

Engineering Selection Recommendations

The main part KPS15-24 is obsolete. Both KPSA15-24 and KPSB25-24 are active and RoHS compliant with matching regulatory agency approvals (CE, CSA, UL). These substitutes provide equivalent or greater output power, conform to the same mounting and package requirements, and include universal input voltage compatibility per the provided data.

Frequently Asked Questions (FAQ)

Q1: What defines a valid substitute for KPS15-24 AC/DC converter?
A1: Valid substitutes must match the input range, output voltage, power rating, mounting type, and regulatory approvals specified for KPS15-24. RoHS compliance is also required.

Q2: Are there differences in mounting or package formats among substitutes?
A2: All listed substitutes use the 4-DIP Module through-hole format, conforming to the main part’s mechanical footprint per the provided specifications.

Q3: Can substitutes support higher output power while remaining compatible?
A3: Substitute models like KPSB25-24 offer increased output power (25W vs. 15W), but maintain identical output voltage, input compatibility, and approvals.

Q4: Are all substitutes compliant with current environmental and safety standards?
A4: All substitute models are RoHS compliant and carry the specified approval agencies (CE, CSA, UL).

Q5: What is the impact of the operating temperature range in substitution?
A5: The substitutes comply with the parameter for 0°C ~ 70°C or greater, as provided. Compatibility for application environments is maintained according to supplied part data.
