Equivalent & Substitute Parts for Vicor VI-24W-EX DC DC Converter

Part Overview

The Vicor VI-24W-EX is an isolated DC DC converter module rated for 75W output power, with a single output of 5.5V at up to 13.64A. It supports an input voltage range from 55V to 100V and provides 3 kV isolation with specific built-in features such as overcurrent, overtemperature, overvoltage, and short circuit protection. VI-24W-EX is provided in a full brick, through-hole package suited for ITE (Commercial) applications. The product is classified as obsolete, which necessitates consideration of compatible substitute models to ensure continued system availability and design maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following key parameters: series, manufacturer, output voltage and current ratings, input voltage range, power rating, isolation voltage, protection features, mounting type, package type, and compliance data. Only parts that strictly align with these electrical and mechanical specifications within this product category are considered valid substitutes.

Key parameters used:

• Series
• Output specifications (number, voltage, current, power)
• Input voltage range
• Isolation voltage
• Operating temperature
• Efficiency
• Mounting type
• Package/case dimensions
• RoHS/REACH compliance
• Certification fields (ECCN, HTSUS)

Parameter Comparison

Engineering Selection Recommendations

The original part, VI-24W-EX, is classified as obsolete. The substitute part VI-24W-EX-B1 is active and matches all electrical, mechanical, and compliance parameters provided, with the only dimensional difference being the module height (1.07" vs. 0.50"). Both parts are RoHS non-compliant and REACH unaffected. Inventory is available for both, subject to standard compliance design controls in this category. If dimensional height is within application allowances, direct substitution is supported on the basis of product status and compliance fields.

Frequently Asked Questions (FAQ)

Q: What are the substitution criteria for VI-24W-EX DC DC converters?
A: Substitution is determined by matching series, output voltage and current ratings, input voltage range, power rating, isolation voltage, operating temperature range, efficiency, mounting type, package type, dimensions, and compliance status.

Q: Are the substitute models within the same series and share the same key electrical specifications?
A: Yes, both VI-24W-EX and VI-24W-EX-B1 are from the Vicor VI-200™ series, with identical electrical specifications.

Q: Is there any difference in mechanical dimensions between the models?
A: The substitute model VI-24W-EX-B1 has a height of 1.07" compared to 0.50" for the original VI-24W-EX. All other length and width dimensions are identical.

Q: Are both parts compliant with RoHS and REACH?
A: Both parts are classified as RoHS non-compliant and REACH unaffected.

Q: Can the substitute part be mounted in the same board footprint?
A: Both parts use full brick, through-hole packages with identical length and width. Height differs, which may impact mechanical clearances.

Q: Does the substitute part have the same protection features and certifications?
A: Both models list the same protection features (OCP, OTP, OVP, SCP) and have matching ECCN and HTSUS certifications as provided.
