Equivalent & Substitute Parts Reference: Vicor VI-B6F-CY DC DC Converter

Part Overview

The Vicor VI-B6F-CY is a DC DC converter module within the VI-200™ (50W) series, featuring isolated design and commercial ITE application compatibility. Key electrical specifications include a single output of 72V at up to 694mA, supporting input voltages from 200V to 400V, providing 50W output power, and operating at up to 90% efficiency. The module utilizes through-hole mounting in a full brick case measuring 4.60" x 2.40" x 0.50". This part is designated as obsolete, making the identification of alternative models essential for continuity in engineering designs using this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based strictly on matching critical electrical and mechanical parameters as provided. The key criteria for direct substitution are:

• Input voltage range (200V – 400V)
• Output voltage and configuration (72V, single output)
• Output current capability (694mA maximum)
• Output power rating (50W)
• Isolation voltage (3 kV)
• Mounting type (Through Hole)
• Package style (Full Brick)
• Feature set (OCP, OTP, OVP, SCP)
• Efficiency (90%)
• Operating temperature range (-25°C ~ 85°C)
• Environmental compliance (RoHS non-compliant, REACH Unaffected)

Parameters must align precisely to qualify as suitable substitutes in engineering and production applications in this product category.

Engineering Selection Recommendations

The VI-B6F-CY is obsolete. The VI-B6F-CY-B1 is active and matches all critical electrical and mechanical specifications provided, aside from increased height dimension (1.07" H vs. 0.50" H). Both modules are RoHS non-compliant and REACH unaffected. For applications requiring an active production status and identical environmental compliance profile, the VI-B6F-CY-B1 is a qualified substitute, with consideration for mechanical height difference as specified.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters required for substituting VI-B6F-CY in power conversion applications?
A1: Substitution requires matching input voltage range, output voltage and current, output power, isolation voltage, mounting type, package dimensions, feature set, efficiency, operating temperature range, and compliance certificates as listed.

Q2: Are the VI-B6F-CY and VI-B6F-CY-B1 interchangeable in circuit designs?
A2: All electrical parameters and mechanical footprint are identical except for package height. Integration is compatible where the increased height (from 0.50" to 1.07") is mechanically permissible.

Q3: How does product status affect substitute selection for these DC DC converters?
A3: An obsolete status indicates unavailability for new projects or long-term support. An active substitute ensures ongoing production and supply, provided all critical parameters are matched.

Q4: What should be considered regarding RoHS and REACH compliance for these modules?
A4: Both modules have RoHS non-compliant status and are REACH unaffected. Substitute selection does not alter compliance profiles with respect to these certifications.

Q5: Does the difference in height between VI-B6F-CY and VI-B6F-CY-B1 affect thermal or mounting requirements?
A5: Mechanical integration is affected only in terms of available vertical clearance; thermal and mounting parameters provided do not indicate any difference except for height. Always verify chassis or enclosure space according to specified package dimensions.
