VI-27M-CY Equivalent & Substitute Parts Reference Guide

Part Overview

The Vicor Corporation VI-27M-CY is an isolated DC-DC converter module, offering a single 10V output at up to 5A with a wide 100V to 375V input range and a maximum output power of 50W. With a 3 kV isolation rating and protection features including OCP, OTP, OVP, and SCP, this module targets ITE (Commercial) applications. The VI-27M-CY is a RoHS non-compliant, full brick, through-hole mounted module with dimensions of 4.60" L x 2.40" W x 0.50" H. This part is classified as Obsolete; as such, identifying strictly compatible alternative models is essential for continued product maintenance or replacements in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution candidates for the VI-27M-CY are determined strictly by matching the following key parameters: output voltage, output current, total power, input voltage range, number of outputs, isolation voltage, protection features, efficiency, package type, mechanical dimensions, and application classification. Only parts meeting these criteria and sharing compliance/certification status are qualified as functionally and mechanically compatible substitutes.

Key parameters defining substitute grouping:

• Output voltage: 10V
• Output current: 5A
• Power: 50W
• Input voltage range: 100V - 375V
• Number of outputs: 1
• Isolation voltage: 3 kV
• Operating temperature: -25°C ~ 85°C
• Features: OCP, OTP, OVP, SCP
• Mounting type: Through Hole
• Package / Case: Full Brick
• RoHS and REACH status

Parameter Comparison

Engineering Selection Recommendations

VI-27M-CY is classified as Obsolete. VI-27M-CY-B1 is an Active status alternative with identical electrical parameters, functional features, protection mechanisms, mounting type, package, and compliance attributes, except for an increased module height. Both parts are RoHS non-compliant and REACH Unaffected. Selection should be based on application requirements for product lifecycle and RoHS status.

Frequently Asked Questions (FAQ)

Q1: What are the most critical electrical parameters for substituting VI-27M-CY?
A1: The most critical parameters are output voltage (10V), output current (5A), total power (50W), and input voltage range (100V - 375V).

Q2: Is VI-27M-CY-B1 functionally equivalent to VI-27M-CY?
A2: Yes, VI-27M-CY-B1 matches VI-27M-CY in all major electrical, functional, and compliance parameters, with only a difference in height (1.07" vs 0.50").

Q3: Does the package size difference impact fit?
A3: Both models use the Full Brick package. However, VI-27M-CY-B1 has a greater height (1.07") compared to VI-27M-CY (0.50"). Ensure system dimensional compatibility prior to selection.

Q4: Are there differences in RoHS or REACH status between VI-27M-CY and substitutes?
A4: Both VI-27M-CY and VI-27M-CY-B1 are RoHS non-compliant and REACH Unaffected.

Q5: Are the protection features identical between main and substitute parts?
A5: Both parts provide over current, over temperature, over voltage, and short circuit protection (OCP, OTP, OVP, SCP).
