Key Parameters

Substitute Part Grouping Explanation

The substitute part, Vicor VI-2NJ-CX-B1, is grouped strictly by matching all critical electrical and mechanical parameters listed. These parameters include: manufacturer, number of outputs, input voltage range, output voltage, maximum output current, output power, voltage isolation, features, application category, operating temperature, efficiency, mounting type, package/case type, and compliance status where specified. Only a physical package height difference exists within the allowed part group.

Parameter Comparison

Engineering Selection Recommendations

Selection of the Vicor VI-2NJ-CX-B1 as a substitute for the obsolete VI-2NJ-CX is supported by matching all specified electrical parameters, features, mounting type, and compliance attributes. Both parts are RoHS non-compliant and REACH unaffected. Product status is the principal differentiator, with the substitute being active. Differences in mechanical height should be verified against physical fit constraints.

Frequently Asked Questions (FAQ)

Q1: What makes the VI-2NJ-CX-B1 interchangeable with the VI-2NJ-CX?
A1: Both parts have identical electrical specifications, thermal ratings, features, and mechanical footprint except for the package height.

Q2: Are there differences in regulatory compliance between these parts?
A2: Both parts are RoHS non-compliant and REACH unaffected, with matching ECCN and HTSUS classifications.

Q3: Is the mounting method and footprint the same for both models?
A3: Both use a through-hole mounting type in a full brick package. The footprint is the same; the only dimensional difference is part height.

Q4: How does the product status affect selection?
A4: The main part, VI-2NJ-CX, is obsolete. The substitute, VI-2NJ-CX-B1, is currently active and available in inventory.

Q5: Do any operating conditions differ between the two parts?
A5: No, both have the same operating temperature range, efficiency, input/output voltages, and current ratings.

Q6: What should be considered regarding the height difference?
A6: Ensure that the available enclosure space accommodates the substitute’s greater package height.

Q7: Do both parts have the same protection features?
A7: Yes, both include OCP (Over-Current Protection), OTP (Over-Temperature Protection), OVP (Over-Voltage Protection), and SCP (Short Circuit Protection).
