Equivalent & Substitute Parts for VI-23J-EX DC-DC Converter

Part Overview

The VI-23J-EX from Vicor Corporation is a DC-DC converter designed as an isolated module with a single 36V output at up to 2.08A, accepting inputs from 42V to 60V. Rated for 75W power, it features integrated protection (OCP, OTP, OVP, SCP), 3kV isolation, and through-hole full brick mounting. The product is classified as obsolete, making it necessary to identify alternative models to ensure continued system operation or support for legacy designs, especially where direct electrical and mechanical compatibility is required.

Substitute Part Grouping Explanation

Substitution grouping between VI-23J-EX and related Vicor VI-200™ models is strictly determined by matching electrical parameters (input voltage range, output voltage, output current, power, isolation voltage), mechanical attributes (mounting type, package/case size/dimensions), product features (OCP, OTP, OVP, SCP), and compliance/certification status. Only parts meeting all listed key parameters within the same series and manufacturer are considered eligible substitutes for the obsolete VI-23J-EX.

Parameter Comparison

Engineering Selection Recommendations

Selection of VI-23J-EX-B1 as an equivalent substitute is based on the product status and compliance fields. VI-23J-EX is obsolete; VI-23J-EX-B1 is active and matches all listed electrical, mechanical, and compliance parameters, including RoHS and REACH status. Both parts are classified under ECCN EAR99 and HTSUS 8504.40.9580. The VI-23J-EX-B1 offers direct substitution without deviation from the required certifications and series attributes.

Frequently Asked Questions (FAQ)

Q: What determines the equivalency of VI-23J-EX and VI-23J-EX-B1 for substitution?
A: Equivalency is determined by matching input/output voltages, output current, output power, isolation voltage, protection features, operating temperature range, mounting type, package/case, and compliance status as listed in the key parameters.

Q: Is there any difference in the physical dimensions that may affect system fit?
A: Both parts share identical length and width (4.60" x 2.40"), while the height of VI-23J-EX-B1 (1.07") differs from VI-23J-EX (0.50"), which could impact systems with strict height constraints.

Q: Are there changes in RoHS or special compliance requirements between these substitutes?
A: Both VI-23J-EX and VI-23J-EX-B1 are RoHS non-compliant and REACH unaffected.

Q: Do the substitute parts have the same protection and efficiency features as the original?
A: Yes, the substitute part matches all protection and efficiency features as specified (OCP, OTP, OVP, SCP; 88% efficiency).

Q: Does the difference in product status (obsolete vs active) impact substitution?
A: Yes. VI-23J-EX is obsolete, and VI-23J-EX-B1 is active, making VI-23J-EX-B1 suitable for ongoing or new designs requiring this function.

Q: Are mounting and package/case formats directly compatible?
A: Both substitutes use through-hole mounting and full brick packaging. Dimensional differences are noted only in height.
