Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Vicor VI-BT4-CW are determined strictly by matching the following key parameters: input voltage range, output voltage and current, power rating, isolation voltage, number of outputs, module type, operating temperature range, efficiency, mounting style, and package/case dimensions. Size variations that do not impact the core electrical specifications are identified explicitly. Substitute parts maintain the same series, protection features, compliance attributes, and are intended for the same target applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between Vicor VI-BT4-CW and VI-BT4-CW-B1 is primarily governed by the product status and regulatory compliance fields. VI-BT4-CW is Obsolete, while VI-BT4-CW-B1 is Active. Both parts are RoHS non-compliant and REACH Unaffected, with the same ECCN and HTSUS codes, ensuring that substitution does not affect certification or regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What parameters must match to substitute the Vicor VI-BT4-CW?
A: Input voltage range, output voltage, output current, power rating, isolation voltage, module type, number of outputs, mounting type, efficiency, feature set, and application classification must all match.

Q: Is there any difference in package size between VI-BT4-CW and VI-BT4-CW-B1?
A: VI-BT4-CW-B1 has a greater height (1.07" vs. 0.50"), while the length and width remain unchanged.

Q: Are there any compliance or environmental certification differences between the original and substitute parts?
A: Both VI-BT4-CW and VI-BT4-CW-B1 are RoHS non-compliant, REACH Unaffected, and share the same MSL, ECCN, and HTSUS classifications.

Q: Does the VI-BT4-CW-B1 maintain the same electrical performance as the VI-BT4-CW?
A: Yes. The VI-BT4-CW-B1 matches all major electrical specifications as the VI-BT4-CW, including input range, output voltage, current, power, and isolation voltage.

Q: Can VI-BT4-CW-B1 be directly installed in the same footprint as VI-BT4-CW?
A: Both use the Full Brick package with unchanged length and width. The height is increased in VI-BT4-CW-B1 and should be reviewed for enclosure clearance.
