VI-27P-CX Equivalent & Substitute Parts Reference
Part Overview
The Vicor Corporation VI-27P-CX is an isolated module DC-DC converter, delivering 13.8V at up to 5.43A output with a wide input voltage range of 100V to 375V, 75W max power, and high efficiency. It is designed for ITE (Commercial) applications, offering over-current, over-temperature, over-voltage, and short-circuit protection. The product is now obsolete, creating a need for alternative models with identical function and form to ensure continuity in designs and systems relying on the VI-27P-CX.

Substitute Part Grouping Explanation
Substitution is determined strictly by the following parameters: input voltage range, output voltage and current, power rating, isolation voltage, module type, number of outputs, protection features, efficiency, operating temperature range, mounting type, and mechanical package dimensions. Only parts matching all these parameters and compliance statuses are eligible as direct substitutes in applications utilizing the VI-27P-CX.

Engineering Selection Recommendations
The VI-27P-CX is obsolete. VI-27P-CX-B1 offers identical electrical and functional parameters, matching certification, compliance, and application suitability. Both modules are RoHS non-compliant and REACH unaffected, allowing for direct replacement in designs where RoHS compliance is not required. Mechanical height differs between models; assessment of vertical clearance in the system is necessary due to the increased height of VI-27P-CX-B1.
Frequently Asked Questions (FAQ)
Q: What makes VI-27P-CX-B1 a substitute for VI-27P-CX?
A: VI-27P-CX-B1 matches all critical electrical, thermal, protection, and operational parameters. Series, isolation, protection features, input/output ratings, efficiency, mounting type, and compliance statuses are identical.
Q: Are there any dimensional differences between the parts?
A: VI-27P-CX-B1 shares length and width but has a greater height (1.07” vs. 0.50”). Fit and form in enclosure or board assembly should be verified.
Q: Is the VI-27P-CX-B1 RoHS compliant?
A: Both VI-27P-CX and VI-27P-CX-B1 are RoHS non-compliant.
Q: Are the electrical connection and pin configuration the same?
A: Both parts utilize the Full Brick package, ensuring consistent pin configuration according to the provided parameters.
Q: Can the substitute part be used in ITE (Commercial) applications?
A: Both modules are specified for ITE (Commercial) use.
Q: Does the substitute part maintain the same application protections (OCP, OTP, OVP, SCP)?
A: All listed protection features are identical.
Q: Is there any change in efficiency or power handling?
A: Efficiency and maximum power rating are identical between the models.
Q: Should other compliance statuses be checked?
A: Both are REACH unaffected and have an MSL of Not Applicable. No differences are present regarding the supplied compliance and status information.
