Equivalent & Substitute Parts Reference for Vicor VI-22R-MX DC DC Converter

Part Overview

The Vicor VI-22R-MX is an isolated module DC-DC converter with an output of 7.5V at up to 10A and a power rating of 75W. It operates within a 21V to 56V input range and provides 3 kV isolation for ITE (Commercial) applications. The module features OCP, OTP, OVP, and SCP protections, is supplied in a through-hole full brick package, and is now obsolete. Identifying alternative models is essential due to discontinued status, enabling sourcing continuity and consistent performance in existing designs requiring these parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Vicor VI-22R-MX DC DC converter is based strictly on matching electrical and mechanical specifications. The key parameters considered for equivalent grouping are: output voltage (7.5V), maximum output current (10A), input voltage range (21V – 56V), output power (75W), isolation voltage (3 kV), series (VI-200™), number of outputs (1), package/case (Full Brick), mounting type (Through Hole), protection features (OCP, OTP, OVP, SCP), efficiency (90%), and operating temperature range (-55°C ~ 85°C). Compliance parameters and status such as RoHS, REACH, MSL, and ECCN are also included.

Parameter Comparison

Engineering Selection Recommendations

The substitute part number VI-22R-MX-B1 maintains all compliance statuses (RoHS non-compliant, REACH unaffected, MSL not applicable, ECCN EAR99) as the main part VI-22R-MX. Substitution can be based strictly on product status, with VI-22R-MX obsolete and VI-22R-MX-B1 designated as active. Series, electrical ratings, and mechanical package type remain within the input values.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the Vicor VI-22R-MX DC DC converter?
A1: Substitution requires matching output voltage, maximum output current, power rating, input voltage range, isolation voltage, number of outputs, series, mounting type, package size, and protection features.

Q2: Does the substitute part VI-22R-MX-B1 differ in compliance or certification from VI-22R-MX?
A2: VI-22R-MX-B1 has the same compliance statuses: RoHS non-compliant, REACH unaffected, MSL not applicable, and ECCN EAR99.

Q3: Are the package types and footprints compatible between VI-22R-MX and VI-22R-MX-B1?
A3: Both are full brick through-hole packages. The physical footprint (length and width) is identical. Height differs, with VI-22R-MX-B1 being 1.07" H and VI-22R-MX at 0.50" H.

Q4: Is the electrical performance equivalent between VI-22R-MX and VI-22R-MX-B1?
A4: The electrical performance parameters provided (output voltage, current, power, input range, isolation, and efficiency) are the same for both parts based on the supplied data.

Q5: Why is substitution necessary for the VI-22R-MX?
A5: Substitution is required because the VI-22R-MX is obsolete. The VI-22R-MX-B1 is active, maintaining supply continuity.
