VI-B5Y-CY Equivalent & Substitute Parts Reference

Part Overview

The VI-B5Y-CY is a DC-DC converter module manufactured by Vicor Corporation. It features a single isolated output of 3.3V at 10A, operates with an input voltage range of 100V to 200V, and is rated for 33W output power. This full brick module is designed for ITE (commercial) applications, incorporates protective features (OCP, OTP, OVP, SCP), and provides 3 kV isolation. The product has been classified as Obsolete, making the identification of functionally equivalent or substitute models essential for continued production support, component replacement, and inventory management.

Parameter Comparison

Engineering Selection Recommendations

When selecting substitutes for the Vicor VI-B5Y-CY DC-DC converter, consider only product status and compliance parameters. The VI-B5Y-CY-B1 is designated as Active, whereas the original VI-B5Y-CY is Obsolete. Both components are RoHS non-compliant and have matching REACH status, MSL, ECCN, and HTSUS codes as specified. Application environments with RoHS or other compliance requirements must note that neither part is RoHS compliant. The size/dimension differs between the two models within the Full Brick category.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if a substitute DC-DC converter is equivalent to VI-B5Y-CY?
A1: Only parts matching all provided electrical (input voltage, output voltage and current, output power, isolation), mechanical (package, mounting type, dimensions), application, operating temperature, protection features, and compliance parameters are considered substitutes.

Q2: Can the VI-B5Y-CY-B1 be used as a direct replacement for VI-B5Y-CY in all designs?
A2: The VI-B5Y-CY-B1 matches all electrical, protection, and application parameters of the VI-B5Y-CY. The only difference is in the overall height dimension; both are full brick modules.

Q3: Are there any RoHS-compliant substitutes provided for VI-B5Y-CY?
A3: No RoHS-compliant substitutes have been identified in the provided parameter set. Both VI-B5Y-CY and VI-B5Y-CY-B1 are RoHS non-compliant.

Q4: What should be considered regarding the package size and dimensions?
A4: Both VI-B5Y-CY and VI-B5Y-CY-B1 are full brick modules with the same length and width. The height differs: 0.50" for VI-B5Y-CY and 1.07" for VI-B5Y-CY-B1. Assess available clearance for component height during component selection.

Q5: Are the compliance, ECCN, and HTSUS details relevant for export or regulatory review?
A5: Both models share identical ECCN (EAR99) and HTSUS (8504.40.9580) codes as specified, and both are designated “Not Applicable” for MSL with “REACH Unaffected” status. Always confirm these fields for regulatory processes using the provided data.
