The audit executor has finished. I’m reconciling its findings, independently verifying the saved datasheet property and reported mismatches, then I’ll publish the concise review.

Audit complete. The official Mean Well datasheet was added and verified; the four-pin footprint geometry and numbering match the datasheet.

Critical mismatch: IRM-30 is a series, not an exact MPN; output voltage/current remain undefined. Select IRM-30-5, -12, -15, -24, or -48.
Missing metadata: manufacturer, part type, package, pin types, and pin descriptions.
The footprint is named IRM-30-5, which may incorrectly imply the 5 V variant.
A Flux part-quality report was filed.

Full specifications, pin mapping, mechanical checks, and mismatch severities are in Part Datasheet Audit.

Inspected project metadata

Table

Item	Actual project value	Datasheet/audit finding
Name	IRM-30	Series name, not a complete orderable model
Description	IRM-30	Too generic to identify output voltage or mounting variant
Manufacturer Part Number	IRM-30	Incomplete: official orderable PCB models require `-5`, `-12`, `-15`, `-24`, or `-48`
Manufacturer Name	Empty	Expected `MEAN WELL` / `Mean Well`
Part Type	Empty	Expected AC-DC encapsulated PCB-mount power-supply module
Designator Prefix	U	Valid syntactically, but `PS` is more semantically appropriate for a power supply
Package/case property	Not populated	Datasheet case is `IRM30`, PCB-mount body 69.5 × 39 × 24 mm
Terminal count	4	Correct for PCB-mount IRM-30
Datasheet URL	Was empty; now populated	Official source verified; persisted as a Flux-managed copy
Lifecycle	Not stated on this project	Current manufacturer page lists active voltage variants

Table

Pad	Project name	Project center (mm)	Hole / copper diameter	Expected function	Result
1	AC/L	(0, 0)	1.0414 / 1.5494 mm	AC line input	Match
2	AC/N	(0, 5.5)	1.0414 / 1.5494 mm	AC neutral input	Match
3	V+	(61.5, 9.0)	1.0414 / 1.5494 mm	Positive DC output	Match (`V+` vs datasheet `+V` is cosmetic)
4	V-	(61.5, 0)	1.0414 / 1.5494 mm	Negative DC output/return	Match (`V-` vs datasheet `-V` is cosmetic)

Fab outline measures approximately 69.4944 × 38.989 mm, effectively matching 69.5 × 39 mm.
Courtyard measures approximately 70.0024 × 39.497 mm.
Pad center geometry exactly follows 5.5 mm, 9.0 mm, and 61.5 mm datasheet spacings.
The 1.0414 mm drill is only 0.0414 mm larger than the nominal 1.0 mm lead. The datasheet does not provide a recommended finished-hole diameter or tolerance for the lead diameter, so solderability/manufacturing allowance cannot be fully validated from the official sheet alone. This is an ambiguity, not a proven geometric mismatch.
The footprint filename explicitly says IRM-30-5, but the mechanical package is shared by all PCB-mount output-voltage variants.

Complete pin mapping and symbol audit

Table

Pin	Datasheet name/function	Project terminal	Actual Pin Type	Actual Pin Description	Assessment
1	AC/L — AC line input	AC/L	Unspecified	Missing	Number/name match; metadata incomplete
2	AC/N — AC neutral input	AC/N	Unspecified	Missing	Number/name match; metadata incomplete
3	+V — positive regulated DC output	V+	Unspecified	Missing	Number/function match; name order cosmetic
4	−V — negative DC output/return	V-	Unspecified	Missing	Number/function match; name order cosmetic

The schematic symbol is implemented as four separated terminal objects rather than a conventional enclosed power-module body. Pin numbers are stored as terminal properties and map correctly. No nets exist. Symbol pin positions place AC inputs on the left and DC outputs on the right, preserving functional direction, but all terminal electrical types are Unspecified and all descriptions are absent.

Mismatches and ambiguities

Table

Severity	Finding	Expected	Actual
Severe	MPN/variant is not uniquely identified	One exact orderable model: IRM-30-5/-12/-15/-24/-48	`IRM-30`, which is the series name only
Severe	Electrical output is therefore undefined	Exact output voltage/current/power must follow selected suffix	No suffix or output property; cannot know which variant the part represents
High	Internal footprint naming biases toward the 5 V model	Footprint asset should be neutral or match exact selected MPN	`IRM-30-5.kicad_mod` while root MPN is only `IRM-30`
Medium	Manufacturer missing	Mean Well	Empty
Medium	Part type missing	AC-DC power-supply module / power source	Empty
Medium	Package/case property missing	IRM30; PCB mount; 69.5 × 39 × 24 mm	Empty
Medium	Terminal electrical types missing	AC pins = power inputs; +V/−V = power output/return as appropriate for ERC	All `Unspecified`
Medium	Terminal descriptions missing	Functional descriptions from datasheet	Empty
Medium	Drill margin is not authoritatively validated	Recommended finished-hole size or adequate tolerance allowance	1.0414 mm hole for nominal 1.0 mm lead; datasheet gives no hole recommendation/lead tolerance
Low	Description is non-informative	Manufacturer, power, topology, input, exact output, mounting	`IRM-30`
Low	Designator prefix is generic IC style	Prefer `PS` for a power supply	`U`
Low	Output terminal names reversed typographically	`+V`, `-V`	`V+`, `V-`; semantics unchanged
Low	Footprint silkscreen value is non-standard	Exact MPN or neutral series marking	`IRM-30_MWU`

Verification evidence

Re-read of project properties confirms a non-empty Datasheet URL persisted after mutation.
Footprint tree inspection confirmed four numbered through-hole pads and the exact coordinates/diameters listed above.
Component review was run after the update. It reports two remaining warnings: Manufacturer Name is not set and Part Type is not set. No datasheet-missing warning remains.
Symbol and footprint geometry were not altered.

Part-quality escalation link

If the lead decides the incomplete MPN/variant identity and IRM-30-5 footprint naming constitute a severe reusable library-part quality issue, use this Flux part/project link:

/silicon-yard/irm-30

The principal escalation statement should be: the published part uses a series-level MPN (IRM-30) despite the official manufacturer offering five electrically different output variants, while its footprint asset is specifically named IRM-30-5; manufacturer, part type, package metadata, terminal types, and terminal descriptions are also missing.
