Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly governed by the following key parameters: manufacturer part number, manufacturer, series, type, number of outputs, input voltage range, output voltage and current specifications, power rating, isolation voltage, application domain, feature set, operating temperature, efficiency, mounting type, package, physical dimensions, compliance attributes, and product status. Compatibility is determined when these parameters are matched between the main part and substitute parts in the same product category.

Parameter Comparison

Engineering Selection Recommendations

The Vicor VI-B6L-CX is obsolete. The substitute VI-B6L-CX-B1 matches all key electrical and mechanical parameters provided, including input and output specifications, feature set, mounting type, package, and compliance attributes. Both models are RoHS non-compliant and REACH unaffected, and share the same ECCN and HTSUS classifications. The substitute part's active status makes it suitable for ongoing production and maintenance under identical compliance and application requirements.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if VI-B6L-CX-B1 can substitute VI-B6L-CX?
Matching parameters include input and output voltage, current, power rating, isolation voltage, feature set, mechanical package, mounting, application type, operating temperature range, compliance, and manufacturer.

Q2: Are there any mechanical differences between the VI-B6L-CX and VI-B6L-CX-B1 that affect substitution?
Both use a Full Brick package with identical length and width; the height differs (0.50" vs. 1.07"), which must be verified for mechanical fit in the intended enclosure.

Q3: Is there any difference in compliance and environmental certifications between the two models?
Both are classified as RoHS non-compliant and entirely REACH unaffected. There are no differences in ECCN or HTSUS codes.

Q4: Can the substitute part be used in the same application category?
Both models are intended for ITE (Commercial) applications and share identical electrical specifications and protective features.

Q5: Does product status affect selection?
As the main part (VI-B6L-CX) is obsolete, selection should be directed towards the substitute (VI-B6L-CX-B1), which holds an active status. This ensures availability for new designs and service requirements.
