Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DC-DC converters in isolated module form must match critical electrical and mechanical parameters. The key substitution criteria are: input voltage range, output voltage, output current, power rating, isolation voltage, protection features, mounting type, package/case, operating temperature range, and product status. Only parts matching all these parameters can be considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part, Vicor VI-20D-EX, is currently obsolete, necessitating substitution for ongoing maintenance or new designs. The substitute, Vicor VI-20D-EX-F1, matches all key parameters outlined, including electrical ratings, features, compliance status, and mounting type. Both parts are RoHS non-compliant, have identical REACH status, and share the same ECCN and HTSUS codes. Selection between them is based strictly on product status and stock availability; the substitute part is active.

Frequently Asked Questions (FAQ)

Q1: What are the substitution criteria for the Vicor VI-20D-EX isolated DC-DC converter?
A1: Substitution is strictly based on matching input voltage range, output voltage, output current, power rating, isolation voltage, protection features, mounting type, package/case, and operating temperature. Compliance parameters and product status are also considered.

Q2: Are the mechanical dimensions identical between VI-20D-EX and VI-20D-EX-F1?
A2: The overall length is the same, but width and height differ. Confirm fit within the intended design footprint by referencing provided size/dimension parameters.

Q3: Is RoHS compliance different between the main and substitute parts?
A3: Both VI-20D-EX and VI-20D-EX-F1 are RoHS non-compliant.

Q4: What is the difference in product status between the two parts?
A4: VI-20D-EX is Obsolete; VI-20D-EX-F1 is Active.

Q5: Can protection features and performance be considered equivalent?
A5: OCP, OTP, OVP, and SCP features are identical per provided data. Efficiency and operating temperature ranges match as well.

Q6: Does the mounting type and package ensure compatibility for direct replacement?
A6: Both parts use Through Hole mounting and full brick package type. Review exact dimensions for physical fit consideration.
