Vicor VI-22J-CX Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-22J-CX is an isolated module DC-DC converter from the VI-200™ (75W) series. It provides 1 output at 36V and up to 2.08A from a 21V to 56V input, featuring OCP, OTP, OVP, and SCP protections and mounting as a full brick through-hole package. The product is listed as obsolete, necessitating identification and selection of substitute parts for ongoing designs and maintenance where exact electrical and mechanical compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on matching the key electrical and mechanical parameters defined for isolated module DC-DC converters. Substitutes must match or exceed the following criteria:

• Series: VI-200™ (75W)
• Manufacturer: Vicor Corporation
• Type: Isolated Module
• Number of Outputs: 1
• Input Voltage Range: 21V to 56V
• Output Voltage: 36V
• Output Current: 2.08A
• Power Rating: 75W
• Isolation Voltage: 3 kV
• Features: OCP, OTP, OVP, SCP
• Operating Temperature: -25°C ~ 85°C
• Efficiency: 90%
• Mounting Type: Through Hole
• Package / Case: Full Brick Substitute selection further considers product status and compliance fields as provided.

Parameter Comparison

Engineering Selection Recommendations

Based on product status, the VI-22J-CX is obsolete, while the VI-22J-CX-B1 is active. Both share identical electrical and most mechanical parameters, differing only by the height dimension of the full brick package. RoHS and REACH statuses match, with both products being RoHS non-compliant and REACH unaffected. For applications requiring active parts or long-term availability within these compliance constraints, select the VI-22J-CX-B1.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for Vicor VI-22J-CX?
Substitution is determined by matching input voltage range, output voltage and current, power rating, isolation voltage, features, mounting type, package/case, operating temperature, efficiency, and compliance status.

Q2: Is VI-22J-CX-B1 a direct form-fit-function replacement?
VI-22J-CX-B1 matches the main electrical specifications and mounting type. The physical dimensions differ only in height (1.07" vs. 0.50"). Application fit must consider this dimension when designing or retrofitting assemblies.

Q3: Are there compliance differences to consider?
Both the main and substitute parts are RoHS non-compliant and REACH unaffected. Selection does not result in different regulatory requirements.

Q4: Is the package form (Full Brick) compatible across substitutes?
Both VI-22J-CX and VI-22J-CX-B1 use the full brick package style and through-hole mounting. Ensure sufficient clearance for height in the assembly when using VI-22J-CX-B1.

Q5: What key parameter differences exist between main and substitute models?
All electrical characteristics align. The only mechanical difference is the height of the package. Verification of mechanical space prior to substitution is necessary.
