Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching all electrical, mechanical, and certification parameters as provided. Only parts with identical or matching values for the following parameters are considered suitable substitutes:

• Input voltage range (10V ~ 20V)
• Output voltage (6.5V)
• Maximum output current (7.69A)
• Power rating (50W)
• Isolation voltage (3 kV)
• Output count (1)
• Protection features (OCP, OTP, OVP, SCP)
• Operating temperature range (-25°C ~ 85°C)
• Efficiency (90%)
• Mounting type (Through Hole)
• Package / case (Full Brick)
• RoHS and REACH compliance Only models with matching or explicitly listed compatible dimensions and certifications are included.

Parameter Comparison

Engineering Selection Recommendations

Selection should prioritize parts with identical series, electrical performance, mechanical mounting, and certified regulatory status as the original Vicor VI-20T-CY. As the VI-20T-CY is obsolete, the Vicor VI-20T-CY-F1 meets all electrical, environmental, and certification parameters provided, while offering a variant in package dimensions. Both models hold a RoHS non-compliant status and are unaffected by REACH, holding the same ECCN and HTSUS designations.

Frequently Asked Questions (FAQ)

Q1: Are the VI-20T-CY and VI-20T-CY-F1 DC-DC converters electrically identical?
A1: Yes, both parts share identical input voltage range, output voltage, maximum output current, power rating, isolation voltage, efficiency, and protection features.

Q2: Can the Vicor VI-20T-CY-F1 directly replace the Vicor VI-20T-CY in an assembly?
A2: The Vicor VI-20T-CY-F1 can be considered a substitute based solely on matching electrical parameters and operational features. Mechanical fit should be checked using the provided package and dimensional data.

Q3: Is there any difference in regulatory compliance between these models?
A3: Both parts are RoHS non-compliant, REACH unaffected, and share the same ECCN and HTSUS codes.

Q4: What package differences exist between the VI-20T-CY and VI-20T-CY-F1?
A4: VI-20T-CY measures 4.60" x 2.40" x 0.50" (116.8mm x 61.0mm x 12.7mm), while VI-20T-CY-F1 measures 4.60" x 1.86" x 0.79" (116.8mm x 47.2mm x 20.1mm).

Q5: Do the substitute models affect RoHS or REACH compliance of the end product?
A5: Both are RoHS non-compliant and REACH unaffected, resulting in no change in overall product compliance status based on this substitution.
