Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified by matching all electrical and mechanical parameters as provided. Substitution eligibility requires equivalence in: manufacturer series, input voltage range, output voltage and current, power rating, isolation voltage, efficiency, number of outputs, package type, and RoHS/REACH compliance status. Only parts meeting all listed criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between the Vicor VI-2NH-CV and VI-2NH-CV-B1 should be based on product availability and compliance requirements. Both parts are RoHS non-compliant and REACH unaffected. VI-2NH-CV is obsolete, while VI-2NH-CV-B1 is active. Dimensional differences in height should be evaluated for fit in mechanical assemblies.

Frequently Asked Questions (FAQ)

Q1: What determines if VI-2NH-CV-B1 is a valid substitute for VI-2NH-CV?
A1: The substitute meets all critical electrical and mechanical parameters including voltage/current ratings, isolation, and package format, with only a difference in module height.

Q2: Are there compliance or certification differences between the main and substitute parts?
A2: Both parts are RoHS non-compliant and REACH unaffected.

Q3: Will the change in module height affect compatibility?
A3: Mechanical compatibility should be verified, as VI-2NH-CV-B1 has a greater height (1.07" vs 0.50"). All other dimensions match.

Q4: Is there a change in electrical performance between the main and substitute parts?
A4: Electrical performance parameters including input/output ratings and efficiency are identical.

Q5: Why is substitution necessary for VI-2NH-CV?
A5: The main part is obsolete, necessitating identification of active alternatives to ensure continuous system function.
