Key Parameters

Substitute Part Grouping Explanation

Substitution for the Vicor VI-B3Y-CW DC DC converter is established strictly on identical electrical and mechanical parameters provided for this product category. The criteria used include: input voltage range (42V to 60V), output voltage (3.3V), maximum output current (20A), power output (66W), voltage isolation (3 kV), efficiency (90%), through hole mounting in full brick package, identical or compatible features (OCP, OTP, OVP, SCP), operating temperature range (-25°C ~ 85°C), and compliance statuses (RoHS, REACH, MSL). Only parts matching all these parameters and provided as substitutes are listed.

Parameter Comparison

Engineering Selection Recommendations

The main part, Vicor VI-B3Y-CW, has an obsolete status and is RoHS non-compliant, with REACH unaffected and MSL not applicable. The substitute part, Vicor VI-B3Y-CW-B1, is active, also RoHS non-compliant, and maintains REACH unaffected status with MSL not applicable. Both parts are suitable for applications where RoHS compliance is not required. Inventory availability and identical compliance attributes support straightforward substitution based on the parameters provided.

Frequently Asked Questions (FAQ)

Q1: What determines if VI-B3Y-CW-B1 is a suitable substitute for VI-B3Y-CW?
A1: Suitability is determined by matching input and output voltages, maximum current, total output power, isolation voltage, protection features, efficiency, mounting type, package, operating temperature, and compliance statuses.

Q2: Are there any differences in mechanical dimensions between VI-B3Y-CW and VI-B3Y-CW-B1?
A2: Yes, the height of VI-B3Y-CW-B1 is 1.07" (27.1mm), while VI-B3Y-CW is 0.50" (12.7mm). Length and width are identical.

Q3: Are both parts RoHS compliant?
A3: Both VI-B3Y-CW and VI-B3Y-CW-B1 are RoHS non-compliant.

Q4: Do both parts have the same features for system protection?
A4: Both models include over-current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), and short-circuit protection (SCP) based on the provided data.

Q5: Can the substitute be used in the same ITE (Commercial) applications?
A5: Both parts are specified for ITE (Commercial) applications according to the input parameters.

Q6: What should be considered if replacing the obsolete part in an existing design?
A6: Ensure the height difference between the main and substitute part does not conflict with system constraints, as all other key parameters and package footprints are matched.
