Part Audit and Datasheet Verification
Worked for 6 mins 19 sec
Completed the part audit and saved the detailed report in
part-audit-dcm3623t50t13a6t70.Key findings: the pinout and 9-pad through-hole ChiP 3623 footprint generally match the Vicor datasheet; the Datasheet URL was already set, so I did not overwrite it. Main issues flagged are unspecified pin types/descriptions, missing explicit package metadata, output pin notation differences vs. datasheet prime notation, and the rounded 161 W description vs. 160 W / 160.8 W datasheet rating.
Fix the pin types and descriptions to match the datasheet.
Thought for 4 sec
I’ll update each terminal’s Pin Type and Pin Description from the Vicor datasheet, then re-read the schematic to verify the metadata.
Thought for 29 sec
The first update applied, but Flux warned that several datasheet-style type labels are non-standard; I’m normalizing those to valid Flux pin types while keeping the datasheet descriptions exact.
Thought for 32 sec
Updated and verified all 9 terminal pin types and descriptions against the Vicor datasheet.
Power pins now use valid Flux types (
Power In / Power Out), while the Pin Description fields preserve the datasheet functions for +IN, -IN, TR, EN, FT, +OUT, and -OUT.Run ERC review

Part Audit: DCM3623T50T13A6T70
Scope
Reviewed available Flux project metadata, schematic terminals, PCB footprint nodes, existing Datasheet URL, Vicor product page, and the linked datasheet content for Vicor DCM3623T50T13A6T70.

The user requested updating the Datasheet property only if no datasheet URL was already set. Since a Datasheet URL is already present and the datasheet query successfully resolved it, I did not overwrite it.
Official / manufacturer source checked
Vicor product page found:
https://www.vicorpower.com/products?productKey=DCM3623T50T13A6T70&productType=cfgThe Vicor page confirms the part family and headline specs, but the scrape did not expose a direct PDF URL. The project’s existing PDF appears to be the relevant Vicor datasheet content:

Footprint / package cross-check
Project layout contains 9 pad nodes matching the required terminal count: +IN, TR, EN, FT, -IN, +OUT_1, +OUT_2, -OUT_1, and -OUT_2. The symbol and footprint both use nine terminals, consistent with the datasheet pinout.
The layout silk / body outline from the flat layout data spans approximately 38.72 mm × 22.8 mm, matching the datasheet 3623 ChiP package dimensions. The available layout data did not expose detailed drill sizes or exact pad coordinates in the structured node listing, so hole size and annular ring dimensions were not independently verified from the footprint data.
Datasheet recommended hole pattern notes include:
- 2.03 mm plated through-hole with 0.38 mm annular ring for 4 pads
- 2.03 mm plated through-hole with 0.25 mm annular ring for 2 pads
- 1.52 mm plated through-hole with 0.25 mm annular ring for 3 pads
Mismatches / issues flagged
-
Pin Type properties are all “Unspecified” in the project.
The datasheet has clear electrical types: input power, input, output, input power return, output power, and output power return. This is the main metadata mismatch. -
Output pin notation differs from datasheet.
The project uses A2/B2/C2/D2 while the datasheet uses A’2/B’2/C’2/D’2. The electrical mapping is correct, but the prime notation is omitted in the project pin numbers. -
No explicit project-level Package property was found.
The correct package is through-hole ChiP 3623, 38.72 × 22.80 × 7.21 mm. -
Datasheet URL is not a direct vicorpower.com PDF URL.
A Datasheet URL is already set to a stored PDF asset, and the official product page did not expose a direct PDF link through web scraping. Since the requested condition was “if no datasheet URL is already set,” I left it unchanged. -
Project description says 161 W while datasheet says 160 W / 160.8 W class.
The datasheet headline rating is 160 W and 13.40 A at 12 V equals 160.8 W. The existing “161W” description is acceptable rounded marketing/parametric wording, but the exact datasheet rating should be recorded as 160 W continuous or 160.8 W calculated.
Recommended cleanup
- Set terminal Pin Type / Pin Description metadata to match the datasheet.
- Add an explicit package metadata field if supported:
Through-hole ChiP 3623, 38.72 × 22.80 × 7.21 mm. - Optionally change the description to:
Vicor DCM3623 isolated regulated DC-DC converter, 9–50 V input, 12 V / 13.4 A / 160 W output, through-hole ChiP 3623. - If a direct Vicor PDF URL becomes available from Vicor’s site, replace the stored Datasheet URL with the official PDF link; otherwise the current stored PDF is usable and queryable.
