VI-24W-CW Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-24W-CW is an obsolete isolated DC-DC converter module designed for ITE (Commercial) applications. It provides a single output of 5.5V at up to 18.18A, accepting a wide input voltage range of 55V to 100V and delivering 100W maximum power. Key electrical and mechanical parameters such as voltage input and output, current rating, isolation voltage, operating temperature range, mounting type, and package dimensions are critical for safe and direct substitution. Sourcing alternatives is necessary due to its product status being marked obsolete, which may impact availability for ongoing or new designs requiring these specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly according to critical matching parameters: input voltage range, output voltage, output current, maximum power output, isolation voltage, operating temperature range, mounting type, and package form factor. Compliance, features, and certifications are also matched. Mechanical differences such as height must be compared to ensure compatibility. Substitution is appropriate when all listed parameters are consistent with the requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

Replacement selection is based on product status, RoHS compliance, ECCN, and HTSUS classification. VI-24W-CW is classified as obsolete, while VI-24W-CW-B1 is active and suitable for substitution in applications where obsolete status is a concern. Both parts are RoHS non-compliant. Compliance, certifications, and classification data provided must match application requirements.

Frequently Asked Questions (FAQ)

Q: What are the primary criteria for substituting VI-24W-CW with VI-24W-CW-B1?
A: Substitute selection requires matching input voltage range, output voltage, output current, power rating, isolation voltage, operating temperature, mounting type, package, and compliance parameters.

Q: Are there differences in package dimensions between VI-24W-CW and VI-24W-CW-B1?
A: Both use Full Brick packaging with identical length and width; however, VI-24W-CW-B1 has a greater height (1.07") compared to VI-24W-CW (0.50").

Q: Is there any change in regulatory compliance between these parts?
A: Both parts are RoHS non-compliant, classified as EAR99 for ECCN, and use HTSUS 8504.40.9580.

Q: Does the status of the main part affect its suitability for ongoing production?
A: VI-24W-CW is obsolete; substituting with the active VI-24W-CW-B1 is suitable when continued sourcing and support are required.

Q: Are operating conditions and electrical ratings identical between the parts?
A: Input voltage, output voltage, output current, power rating, isolation, efficiency, and operating temperature range are identical.

Q: What mechanical consideration is necessary when substituting these modules?
A: The height difference in Full Brick package may affect fit in certain assemblies and should be reviewed according to application requirements.
