Equivalent & Substitute Parts for Vicor VI-24K-CY DC DC Converter

Part Overview

The Vicor VI-24K-CY is an isolated DC DC converter module, delivering 40V at up to 1.25A from a 55V to 100V input range, rated for 50W output power. It features overcurrent, overtemperature, overvoltage, and short circuit protection, 3 kV isolation, and is housed in a full brick through-hole package. The product status is Obsolete, making it necessary to identify alternative models that meet the same electrical and mechanical requirements for design continuity and procurement stability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DC DC converters like the Vicor VI-24K-CY must match critical electrical and mechanical parameters. These include input voltage range, output voltage and current, output power, isolation voltage, number of outputs, protection features, mounting type, and package dimensions. All listed parameters are directly provided and are required for direct substitution in design and functional applications. Only parts with exact matches to these specifications can be considered suitable alternatives.

Parameter Comparison

Engineering Selection Recommendations

Selection of the Vicor VI-24K-CY-B1 as a substitute is based on its active product status, matching electrical parameters, identical compliance status (RoHS non-compliant, REACH unaffected, ECCN EAR99, HTSUS 8504.40.9580), and consistent mounting type and package. The only difference in package dimension is the height (1.07" versus 0.50"). This must be considered in applications where vertical clearance is restricted.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting the Vicor VI-24K-CY DC DC converter?
A1: Substitute criteria are strictly based on input voltage range, output voltage and current, output power, isolation voltage, protection features, mounting type, and package dimensions as provided in the technical parameters.

Q2: Does the substitute part VI-24K-CY-B1 differ electrically from the VI-24K-CY?
A2: No, all electrical characteristics, including input/output specifications, isolation, efficiency, and protection features, are identical per provided data.

Q3: Is there any compliance or certification difference between the original and substitute parts?
A3: Both parts are specified as RoHS non-compliant, REACH unaffected, ECCN EAR99, and share the same HTSUS code.

Q4: What mechanical differences exist between the VI-24K-CY and VI-24K-CY-B1?
A4: The main difference is in package height—VI-24K-CY has a height of 0.50", while VI-24K-CY-B1 has a height of 1.07". Width and length are identical.

Q5: How does product status affect selection?
A5: VI-24K-CY is Obsolete. VI-24K-CY-B1 is Active, making it suitable for ongoing supply and new designs under the given parameters.

Q6: Is thermal or mechanical requalification needed for the substitute?
A6: Only the specified package height difference affects mechanical fit and should be confirmed for system integration where vertical space is limited.

Q7: Can substitute parts be used interchangeably in all applications?
A7: Substitute use is strictly determined by matching all specified parameters, particularly electrical ratings and mechanical dimensions as provided.
