Vicor VI-27P-EX Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-27P-EX is an obsolete DC-DC converter module providing isolated, regulated 13.8V output at 5.43A, with a power rating of 75 W and wide input voltage range of 100V to 375V. Typical applications are in Information Technology Equipment (ITE), requiring features such as output overcurrent, overtemperature, overvoltage, and short circuit protection. Alternative models must be referenced for continued manufacturing, replacement, or maintenance support due to its obsolete product status.

Key Parameters

Substitute Part Grouping Explanation

The substitute grouping is based strictly on matching the following key parameters: series (VI-200™ 75W), type (Isolated Module), input voltage range (100V to 375V), output voltage (13.8V), output current (5.43A), power rating (75 W), voltage isolation (3 kV), features (OCP, OTP, OVP, SCP), mounting type (Through Hole), package size (Full Brick form factor), operating temperature (-10°C to 85°C), and RoHS status. Only parts meeting all these criteria are considered approved substitutes. The substitute part must also serve the same target application (ITE Commercial) and possess the same core protection features.

Parameter Comparison

Engineering Selection Recommendations

The VI-27P-EX part is obsolete. The suggested substitute, VI-27P-EX-B1, is active and matches all specified electrical, mechanical, and compliance parameters. Both parts are classified as RoHS non-compliant, suitable for use in applications where this status is acceptable. All certifications and compliance statuses are identical between the original and substitute parts.

Frequently Asked Questions (FAQ)

Q: What allows VI-27P-EX-B1 to be a direct substitute for VI-27P-EX?
A: The VI-27P-EX-B1 matches all electrical parameters (input range, output voltage and current, power, isolation), mechanical parameters (full brick footprint, through hole mount), application classification, and compliance fields specified for VI-27P-EX.

Q: Are there any critical dimensional differences between VI-27P-EX and VI-27P-EX-B1?
A: Both maintain the same length and width. The height changes from 0.50" (12.7mm) for VI-27P-EX to 1.07" (27.1mm) for VI-27P-EX-B1. This must be considered if there are clearance constraints in the assembly.

Q: Do both parts provide the same certifications and compliance levels?
A: Both are RoHS non-compliant, REACH unaffected, and classified under the same ECCN and HTSUS numbers.

Q: Is the substitute part suitable for the same operating environment?
A: Yes, both are rated for -10°C to 85°C, through hole mounting, and feature identical function and protection sets.

Q: Can the substitute be used in all mechanical configurations where VI-27P-EX was used?
A: The mounting type and footprint remain unchanged; only the case height differs. Where enclosure height is not restricted, the VI-27P-EX-B1 can be fitted directly.

Q: Is there any difference in protection or feature set between these parts?
A: Both include OCP (Over Current Protection), OTP (Over Temperature Protection), OVP (Over Voltage Protection), and SCP (Short Circuit Protection), as specified.
