• Input Voltage Range
• Output Voltage(s)
• Maximum Output Current and Power
• Isolation Voltage
• Application
• Protection/Feature set
• Operating Temperature Range
• Efficiency
• Mounting Type
• Package / Case
• Size / Dimension
• RoHS and REACH status

Parameter Comparison

Engineering Selection Recommendations

When selecting between the Vicor VI-22X-MW and VI-22X-MW-B1, product status is a primary criterion. The VI-22X-MW is obsolete, whereas the VI-22X-MW-B1 is active. Both parts are RoHS non-compliant and share identical compliance profiles with respect to REACH status and ECCN. Selection is determined by application requirements for active lifecycle status and compliance alignment.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to identify substitute DC-DC converters for the Vicor VI-22X-MW?
A1: Substitution is based strictly on matching the input voltage range, output voltage and current, total output power, isolation voltage, protection features, mechanical form factor, operating temperature range, and compliance attributes.

Q2: Is the VI-22X-MW-B1 mechanically interchangeable with the VI-22X-MW?
A2: Both are Full Brick through-hole modules with matching length and width. The height differs: VI-22X-MW is 0.50" (12.7mm), VI-22X-MW-B1 is 1.07" (27.1mm).

Q3: Is there any difference in electrical or regulatory compliance between VI-22X-MW and VI-22X-MW-B1?
A3: Both models share identical electrical specifications and regulatory status for RoHS (non-compliant) and REACH (unaffected).

Q4: Is there an impact if the obsolete part is replaced with the substitute in existing designs?
A4: Substitution is supported by matching electrical and mechanical key parameters. Mechanical height should be verified for physical clearance in the target design.

Q5: Does the substitute VI-22X-MW-B1 offer continued supply assurance?
A5: The VI-22X-MW-B1 is listed as active, providing continuity of supply where the VI-22X-MW is obsolete.
