Part Review and Datasheet Update
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 4 sec
I’ll inspect the part metadata, look for an official datasheet if needed, then compare symbol/footprint/pins against the datasheet and report any mismatches.

I found an official RECOM datasheet URL in addition to the existing uploaded PDF; I’ll finish the pin/footprint comparison and record the detailed review in a project file.

Completed the part review for RACM30-15DK/277 and documented it in Part Review: RACM30-15DK/277. The MPN, 5-pin THT package, pinout, and footprint topology match the official RECOM datasheet; flagged cleanup items are the uploaded-copy datasheet URL, missing explicit pin descriptions, unspecified pin types, and drill/pad size confirmation before manufacturing.

Datasheet pinout vs schematic symbol
Datasheet THT dual-output pinning:
Table
| Pin | Datasheet function | Flux terminal/designator | Result |
|---|---|---|---|
| 1 | VAC in (N) | VAC_IN_(N), Pin Number 1 | Match |
| 2 | VAC in (L) | VAC_IN_(L), Pin Number 2 | Match |
| 3 | -Vout | -VOUT, Pin Number 3 | Match |
| 4 | Com | COM, Pin Number 4 | Match |
| 5 | +Vout | +VOUT, Pin Number 5 | Match |
Symbol pin positions place AC input pins on the left and DC output pins on the right, which matches expected functional grouping.
Footprint check
Observed footprint pads:
- 5 pads present: VAC_IN_(N), VAC_IN_(L), -VOUT, COM, +VOUT.
- Pin 1 is rectangular, remaining pads are circular, which is appropriate for pin-1 identification.
- Relative pad pattern matches the datasheet THT layout in topology:
- AC pins at x=0 with 20.32 mm vertical spacing.
- Output pins offset 45.72 mm from AC pins.
- Output pins spaced at 10.16 mm intervals vertically.
- Pad/hole size appears as
0.0018in tool output while the rule unit is reported as mm. This likely corresponds to a 1.8 mm pad diameter in internal units, but the displayed unit scaling is ambiguous. Datasheet recommends Ø1.20 mm holes for Ø1.0 ±0.1 mm pins, so confirm the actual plated hole/drill and annular ring in the footprint editor/export before release.
Mismatches / issues flagged
- Datasheet URL source: Existing Datasheet URL is an uploaded storage copy, not the official RECOM URL. The official URL is
https://recom-power.com/pdf/Powerline_AC-DC/RACM30-K_277.pdf. If Flux part policy prefers vendor-hosted URLs, update the property to the official URL. - Pin descriptions are not populated as explicit Pin Description properties: Terminal designators and pin numbers are correct, but the inspected terminal properties do not show dedicated
Pin Descriptionfields. Adding descriptions such asVAC in (N),VAC in (L),-Vout,Com, and+Voutwould improve library quality. - Pin Type is
Unspecifiedon all terminals: For better ERC/library semantics, consider assigning AC input pins as power/input and DC output pins as power/output or appropriate passive/power terminal types. - Footprint drill/pad size needs export-level confirmation: The layout shows 5 pads in the correct topology, but the tool output’s pad size unit is ambiguous. Verify actual drill diameter is Ø1.20 mm and pad diameter provides adequate annular ring.
Conclusion
The core MPN, manufacturer, package class, pin count, pin numbering, and functional pinout match the official RECOM datasheet for RACM30-15DK/277 THT dual-output version. No critical pinout mismatch was found. Recommended cleanup is metadata quality: use the official RECOM datasheet URL, add explicit pin descriptions, assign more specific pin types, and confirm the footprint drill/pad dimensions before manufacturing use.
