Vicor VI-22Y-CY Equivalent & Substitute DC DC Converter Reference

Part Overview

The Vicor VI-22Y-CY is an isolated module DC DC converter designed for commercial ITE applications. It provides a single regulated output of 3.3V at up to 10A, supporting input voltages from 21V to 56V and delivering a maximum output power of 33W. This device is housed in a full brick through-hole package with advanced protection features including OCP, OTP, OVP, and SCP. The VI-22Y-CY is classified as obsolete, necessitating the identification of substitute parts with matching electrical and mechanical parameters to ensure continued system operation where direct replacement is required.

Substitute Part Grouping Explanation

Substitute part identification for the Vicor VI-22Y-CY is strictly based on matching essential electrical and mechanical characteristics as provided:

• Input voltage range (21V–56V)
• Output voltage and current (3.3V, 10A)
• Output power (33W)
• Isolation voltage (3 kV)
• Package type and physical dimensions
• Mounting method (through hole)
• Operating temperature (-25°C ~ 85°C)
• Functional features (OCP, OTP, OVP, SCP)
• Compliance status (RoHS, REACH, ECCN, HTSUS)

Compatibility is confirmed only when a substitute part aligns with these parameters.

Parameter Comparison

Engineering Selection Recommendations

VI-22Y-CY is classified as obsolete while VI-22Y-CY-B1 remains active. Both parts share non-compliant RoHS status, identical REACH unaffected status, and the same ECCN and HTSUS codes. Selection between these parts should be based on inventory availability and the requirement for an active product status. Ensure that package height differences are accommodated in the design.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting Vicor VI-22Y-CY with VI-22Y-CY-B1?
A1: Substitution is based on matching input and output voltage, output current, isolation voltage, power rating, mounting type, functional features, compliance status, package, and size.

Q2: Are there differences in package size or format between VI-22Y-CY and VI-22Y-CY-B1?
A2: Both use the same full brick format; however, VI-22Y-CY-B1 has greater height (1.07" vs. 0.50"). Verify mechanical fit within the application.

Q3: Does VI-22Y-CY-B1 maintain identical electrical and thermal operating limits as VI-22Y-CY?
A3: All provided electrical and thermal operating ratings are matched between the two models.

Q4: Are there any compliance differences to consider?
A4: Both are RoHS non-compliant and REACH unaffected. ECCN and HTSUS values are identical.

Q5: Is it valid to use an active product status part as a substitute for an obsolete one?
A5: Yes, provided all critical parameters match and compliance status aligns with application requirements.
