Vicor VI-22P-CX Equivalent & Substitute DC-DC Converter Reference

Part Overview

The Vicor VI-22P-CX is an obsolete Isolated Module DC-DC converter, offering a single 13.8V output at up to 5.43A with a wide 21V to 56V DC input range and 75W maximum power. It operates with high efficiency (90%) and provides enhanced protection features such as overcurrent protection (OCP), overtemperature protection (OTP), overvoltage protection (OVP), and short-circuit protection (SCP). As a full brick through-hole module, it is designed for ITE (Commercial) applications and is RoHS non-compliant. The discontinued status necessitates identifying directly substitutable parts matching all critical electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching key electrical and mechanical parameters. Substitute DC-DC converter modules must have:

• Identical input voltage range (21V - 56V)
• Same output voltage (13.8V) and maximum current rating (5.43A)
• Equal or higher power rating (75 W)
• Equivalent isolation voltage (3 kV)
• Same protection features (OCP, OTP, OVP, SCP)
• Matching operating temperature range (-25°C ~ 85°C)
• Same efficiency (90%)
• Identical mounting type (Through Hole) and package/case (Full Brick) with similar size/dimension
• Same RoHS and REACH compliance statuses

Parameter Comparison

Engineering Selection Recommendations

Both Vicor VI-22P-CX and VI-22P-CX-B1 meet identical key electrical and mechanical specifications. The VI-22P-CX-B1 is the recommended substitute as it is active and directly replaces the obsolete VI-22P-CX without altering compliance, RoHS status, Inventory/HTSUS/ECCN codes, or mechanical format except for an increased height. There are no differences in product certifications or regulatory status.

Frequently Asked Questions (FAQ)

Q1: How is compatibility determined for the Vicor VI-22P-CX and its substitutes?
Compatibility is determined by matching all provided electrical parameters (input range, output voltage/current, power, isolation), thermal range, features, and mechanical characteristics.

Q2: Are the VI-22P-CX and VI-22P-CX-B1 mechanically interchangeable?
Both parts use the same full brick package; the only dimensional difference is increased height in the VI-22P-CX-B1 (1.07" vs. 0.50"). Mechanical fit must be considered with respect to available PCB and enclosure height.

Q3: Are there differences in certifications or statuses (RoHS, REACH, ECCN, HTSUS) between main and substitute parts?
No. Both parts share identical compliance designations and regulatory codes as provided.

Q4: Can the VI-22P-CX-B1 be directly substituted in existing designs using VI-22P-CX?
All provided key electrical parameters and mounting methods are identical, supporting direct substitution where height increase does not impact mechanical allowances.

Q5: What protection features are maintained in the substitute model?
Both the VI-22P-CX and VI-22P-CX-B1 include OCP, OTP, OVP, and SCP as standard features.
