VI-24J-CW Equivalent & Substitute Parts Engineering Reference

Part Overview

The Vicor Corporation VI-24J-CW is an isolated module DC-DC converter in the full brick category, offering 1 output at 36V and up to 2.78A from a 55V–100V input range. It is rated for 100 W power, features 3 kV isolation, and operates across -25°C to 85°C. With on-board protection features (OCP, OTP, OVP, SCP) and 90% efficiency, it is suitable for ITE (Commercial) applications. As the product status is marked "Obsolete," identification of alternative models with matching parameters is critical for design continuity, repair, and long-term support.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based strictly on matching the following key electrical and mechanical parameters: input voltage range, output voltage and current, output power, isolation voltage, number of outputs, features, operating temperature, efficiency, mounting type, package/case, size/dimensions, regulatory compliance (RoHS/REACH), MSL, ECCN, and HTSUS. Only parts meeting these explicit parameters are considered suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part, VI-24J-CW, is classified as obsolete. The substitute part, VI-24J-CW-B1, is identified as active and matches all listed key electrical, thermal, and mechanical parameters except for the height in its package dimensions. Both parts are RoHS non-compliant and REACH unaffected. Both parts have the same ECCN and HTSUS codes and are rated as not moisture sensitive (MSL: Not Applicable).

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a substitute DC-DC converter to be considered equivalent to VI-24J-CW?
A1: The input voltage range, output voltage and current, output power, isolation voltage, number of outputs, protection features, operating temperature range, efficiency, mounting type, package/case, size/dimensions, and compliance status must align with those specified for VI-24J-CW.

Q2: Can VI-24J-CW-B1 be used as a direct replacement for VI-24J-CW in existing designs?
A2: VI-24J-CW-B1 matches all key electrical and functional parameters provided. Attention should be given to the difference in package height when considering mechanical fit in existing designs.

Q3: Are there compliance differences between VI-24J-CW and VI-24J-CW-B1?
A3: Both parts are classified as RoHS non-compliant and REACH unaffected. Both are MSL: Not Applicable and possess the same ECCN and HTSUS designations.

Q4: Does the package size variation impact substitution?
A4: The length and width of both parts are identical. The substitute part, VI-24J-CW-B1, has a greater height than VI-24J-CW.

Q5: What mounting options are available for both parts?
A5: Both VI-24J-CW and VI-24J-CW-B1 are through-hole mountable and in full brick packages.
