Parameter Comparison

Engineering Selection Recommendations

Selection between the Vicor VI-2NJ-CY and VI-2NJ-CY-B1 should prioritize product status. VI-2NJ-CY is obsolete, while VI-2NJ-CY-B1 remains active. Both modules are RoHS non-compliant and unaffected by REACH, with identical electrical and mechanical parameters except for height. Their ECCN and HTSUS codes match, ensuring consistent regulatory classification.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the Vicor VI-2NJ-CY DC DC converter module?
A1: Substitution requires identical input range, output voltage and current, power rating, series, protection features, isolation voltage, mounting type, package/case, application category, and compliance/certification status.

Q2: Are there any differences in electrical or operating performance between VI-2NJ-CY and VI-2NJ-CY-B1?
A2: No differences are present in input voltage, output voltage, current, power, efficiency, isolation voltage, protection features, mounting type, or operating temperature range based on provided parameters.

Q3: What is the impact of the package size variation between these models?
A3: Both models share length and width (4.60" x 2.40"). The height differs: VI-2NJ-CY (0.50") and VI-2NJ-CY-B1 (1.07"), requiring mechanical accommodation for VI-2NJ-CY-B1 if replacing in existing assemblies.

Q4: How should compliance status affect substitute selection?
A4: Both modules are RoHS non-compliant and REACH unaffected, with identical ECCN and HTSUS codes. Substitute selection remains unaffected based on compliance parameters provided.

Q5: Do mounting and mechanical form factors influence system compatibility?
A5: Both models use through-hole mounting and the full brick package type. Compatibility is determined by adherence to published mechanical dimensions. The height discrepancy must be considered for enclosure or PCB layout constraints.
