Vicor VI-B7Y-CY Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-B7Y-CY is an obsolete isolated DC-DC converter module, delivering a single 3.3V output at up to 10A with 33W power capability and 3 kV isolation. Due to its obsolete status and RoHS non-compliance, identification of functionally identical substitute models—especially from the same Vicor VI-200™ series—is critical for ongoing maintenance, repair, and compatible design-in scenarios where identical input/output parameters and mechanical constraints must be observed.

Parameter Comparison

Engineering Selection Recommendations

Selection between Vicor VI-B7Y-CY and VI-B7Y-CY-B1 is primarily determined by product status and available compliance declarations. Both models are RoHS non-compliant and REACH Unaffected, with the VI-B7Y-CY listed as Obsolete and VI-B7Y-CY-B1 as Active. All provided certifications, electrical, and mechanical attributes must be matched exactly as shown, especially size/dimension, mounting, and electrical limits for strict substitution.

Frequently Asked Questions (FAQ)

Q: What criteria are essential when selecting a substitute for Vicor VI-B7Y-CY?
A: Key criteria include matching input voltage range (100V-375V), output voltage (3.3V), output current (10A max), power rating (33 W), isolation rating (3 kV), package type (Full Brick), mounting style (Through Hole), operating temperature (-25°C ~ 85°C), RoHS/REACH declarations, and mechanical dimensions.

Q: Are there any compliance or certification concerns between VI-B7Y-CY and VI-B7Y-CY-B1?
A: Both models are RoHS non-compliant and REACH Unaffected, with the same ECCN and HTSUS codes.

Q: How does the size or height affect drop-in replacement compatibility?
A: The VI-B7Y-CY is 0.50" (12.7mm) high, while VI-B7Y-CY-B1 is 1.07" (27.1mm) high. Physical fit in the end system must be checked against height restrictions for mechanical compatibility.

Q: Are the electrical protections identical between parts?
A: Both models feature OCP (Over Current Protection), OTP (Over Temperature Protection), OVP (Over Voltage Protection), and SCP (Short Circuit Protection).

Q: Is Active status preferred for ongoing designs?
A: The active (VI-B7Y-CY-B1) status indicates continued manufacturer support and new inventory availability, in contrast to the obsolete status of VI-B7Y-CY.

Q: Do mounting styles or pinout arrangements differ?
A: Both parts use Through Hole mounting in a Full Brick package. Pinout is not specified beyond package reference.

Q: Is there a difference in efficiency or electrical performance?
A: Both parts list identical efficiency (90%) and electrical characteristics based on provided data.
