Equivalent & Substitute Parts Engineering Reference for Vicor VI-24K-MU

Part Overview

Vicor VI-24K-MU is a DC-DC Converter module, part of the VI-200™ (200W) series, designed with isolated outputs for ITE (Commercial) applications. The module offers one output at 40V and up to 5A, accepting input voltages between 55V and 100V, with an isolation rating of 3 kV. Efficiency is specified at 90%, operating over a temperature range of -55°C to 85°C, featuring OCP, OTP, OVP, and SCP protection. The mounting type is through-hole, in a full brick package with specific dimensions.

This part is classified as obsolete, necessitating the identification of equivalent or substitute models to ensure continuity of design and supply for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is constrained to parts sharing identical key parameters: input voltage range, output voltage and current, isolation voltage, efficiency, mounting type, package/case, feature set, and compliance status. Only parts within the VI-200™ (200W) series, matching the precise electrical and mechanical specifications, qualify for direct replacement.

Critical substitution criteria:

• Voltage and current ratings
• Isolation and efficiency
• Mounting type and physical dimensions
• Compliance and regulatory status
• Product status (Active vs Obsolete)

Parameter Comparison

Engineering Selection Recommendations

When selecting substitute parts for the obsolete Vicor VI-24K-MU DC-DC converter, the VI-24K-MU-B1 is an equivalent model in the same VI-200™ (200W) series. It matches all critical electrical and mechanical parameters relevant to DC-DC converter modules. The only difference is in physical height. Both are RoHS non-compliant and REACH unaffected, and carry identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for substituting DC-DC converters in the VI-200™ (200W) series?
A1: Input voltage range, output voltage and current, isolation voltage, mounting type, feature set, and compliance status are critical for direct substitution.

Q2: How does the size difference impact compatibility between VI-24K-MU and VI-24K-MU-B1?
A2: Both models use the full brick form factor, with identical length and width; height differs. Application mechanical clearances must be considered.

Q3: Are there compliance or regulatory implications in substituting these models?
A3: Both variants are classified as RoHS non-compliant and REACH unaffected, suitable for applications where these compliance attributes are acceptable.

Q4: Is system performance or protection affected when substituting VI-24K-MU with VI-24K-MU-B1?
A4: Both models share identical electrical performance characteristics and protection features as specified.

Q5: Does product status affect substitution suitability?
A5: VI-24K-MU is obsolete; VI-24K-MU-B1 is active, making it suitable as a direct substitute based on provided information.
