VI-22P-IY Equivalent & Substitute Parts Reference

Part Overview

restarts
The Vicor Corporation VI-22P-IY is an isolated DC-DC converter module providing 13.8V at 3.62A output, with a 21V to 56V input range, 50W output power, and 3 kV isolation rating. It features through-hole mounting, full brick form factor, and includes OCP, OTP, OVP, and SCP protections for ITE (Commercial) applications. The product status is Obsolete, which creates the need to identify alternative models with matching electrical, mechanical, and compliance characteristics for direct substitution in assemblies and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by strict alignment of electrical and mechanical parameters: input voltage range, output voltage and current ratings, total output power, voltage isolation rating, number of outputs, operational features, operating temperature, efficiency, mounting type, and package dimensions. Compliance with RoHS, MSL, REACH, ECCN, and HTSUS are also considered. Only parts matching all specified criteria are grouped as viable direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part number, VI-22P-IY, is classified as Obsolete; the substitute VI-22P-IY-B1 is Active. Both are RoHS non-compliant, REACH Unaffected, and carry the same ECCN and HTSUS codes. Selection between these models should be governed by product status and compliance with specific project certifications as required.

Frequently Asked Questions (FAQ)

Q: What are the key substitution criteria for VI-22P-IY?
A: Key criteria are matching output voltage (13.8V), output current (3.62A), input voltage range (21V to 56V), power rating (50 W), isolation (3 kV), features (OCP, OTP, OVP, SCP), temperature range (-40°C ~ 85°C), efficiency (90%), mounting type (Through Hole), and package type (Full Brick).

Q: Is VI-22P-IY-B1 mechanically compatible with VI-22P-IY?
A: VI-22P-IY-B1 shares the same base length and width (4.60" x 2.40") but has a greater height (1.07" vs. 0.50").

Q: Are both parts RoHS compliant?
A: Both VI-22P-IY and VI-22P-IY-B1 are RoHS non-compliant.

Q: Do both parts have identical protections and features?
A: Yes, both models include OCP (Over Current Protection), OTP (Over Temperature Protection), OVP (Over Voltage Protection), and SCP (Short Circuit Protection).

Q: Can VI-22P-IY-B1 be used as a direct replacement for VI-22P-IY without further qualification?
A: Substitution is based strictly on matching electrical, mechanical, and compliance parameters as provided. The main dimensional difference is the product height.

Q: What package considerations exist when replacing VI-22P-IY with VI-22P-IY-B1?
A: Ensure the increased height (1.07" for VI-22P-IY-B1 vs. 0.50" for VI-22P-IY) is compatible with all mechanical and system integration requirements.
