Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching critical electrical and mechanical parameters, ensuring the functional equivalence of the DC DC converter within the system. Allowed substitution is strictly based on:

• Series and product type: VI-200™ (100W); Isolated Module
• Number of outputs: 1
• Input voltage range: 36V–76V
• Output voltage: 6.5V
• Maximum output current: 15.38A
• Continuous power: 100 W
• Isolation voltage: 3 kV
• Feature set: OCP, OTP, OVP, SCP
• Operating temperature range: -10°C ~ 85°C
• Efficiency: 88%
• Mounting and package: Through Hole, Full Brick Parts are eligible for substitution only if all listed parameters match exactly.

Parameter Comparison

Engineering Selection Recommendations

The main part, VI-2NT-EW, is obsolete. The substitute part, VI-2NT-EW-B1, is active and offers identical electrical parameters, mounting type, feature set, and certifications. Both parts are RoHS non-compliant and have unaffected REACH status. Mechanical differences are limited to the height of the package, which does not alter mounting type or footprint as per provided data. Given matching compliance and certifications, the substitute part can be selected where the mechanical envelope accommodates the different height dimension.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a VI-2NT-EW substitute?
A1: Substitution is valid when part number, series, type, number of outputs, input/output voltages, output current, power rating, isolation voltage, operating temperature, efficiency, mounting type, package/case, compliance status, and listed features are equivalent.

Q2: Does the substitute VI-2NT-EW-B1 maintain the same electrical performance?
A2: VI-2NT-EW-B1 matches all specified electrical parameters, including output, input range, features, and efficiency, ensuring functional equivalence within the design.

Q3: Are there differences in mechanical size or packaging between VI-2NT-EW and substitutes?
A3: VI-2NT-EW-B1 has a greater height (1.07" vs 0.50"), but shares the same length, width, and mounting type (Full Brick, Through Hole).

Q4: How do compliance and certification affect substitution?
A4: Both VI-2NT-EW and VI-2NT-EW-B1 are RoHS non-compliant, REACH unaffected, and classified as ECCN EAR99 and HTSUS 8504.40.9580, permitting substitution within environments where compliance criteria are consistent.

Q5: Can I use VI-2NT-EW-B1 in the same PCB footprint as VI-2NT-EW?
A5: Both parts are Full Brick, Through Hole modules with the same length and width; confirm vertical clearance in the application to accommodate the substitute's height.
