Completed the IRM-45-24 part review and created the detailed report: Part Review - IRM-45-24.
Open items flagged:
- No definite pinout or footprint mismatch found.
- Pin descriptions are missing and pin types are currently
Unspecified. - Datasheet URL was already set, so I did not change it; official Mean Well URL was found and noted in the report.
- Optional review: verify bottom-view footprint orientation visually before publishing/production use.
Suggested next steps:
- Add pin descriptions and meaningful pin types.
- Optionally update/supplement the Datasheet URL with the official Mean Well PDF.
- Optionally add package/case metadata: IRM60, PCB mount, 87 × 52 × 29.5 mm.

Schematic Symbol Cross-Check
Existing symbol is represented as four terminal pins:
Table
| Existing pin number | Existing designator/name | Datasheet function | Result |
|---|---|---|---|
| 1 | AC/L | AC line input | Match |
| 2 | AC/N | AC neutral input | Match |
| 3 | -V | DC output negative / return | Match |
| 4 | +V | DC output positive | Match |
Symbol findings
- Pin count and pin numbering match the datasheet assignment.
- Terminal placement is logically arranged with AC input on the left and DC output on the right.
- All four terminals currently have
Pin Type: Unspecified; this should be improved for ERC clarity. - No explicit
Pin Descriptionproperties are present. This is the main symbol metadata gap.
Suggested pin metadata:
Table
| Pin | Name | Suggested Pin Type | Suggested Pin Description |
|---|---|---|---|
| 1 | AC/L | Power Input | AC line input |
| 2 | AC/N | Power Input | AC neutral input |
| 3 | -V | Power Output or Power | DC output negative / return |
| 4 | +V | Power Output or Power | DC output positive, +24 V nominal |
Footprint Cross-Check
Existing footprint asset:
IRM4524.kicad_mod.Body / outline
Table
| Footprint feature | Existing value | Datasheet value | Result |
|---|---|---|---|
| Body length | 87 mm from x=-5.3 to x=81.7 | 87 mm | Match |
| Body width | 52 mm from y=-5 to y=47 | 52 mm | Match |
| PCB style height | 3D model only, not derived from 2D pads | 29.5 mm | 2D footprint cannot fully verify; 3D model asset exists |
| Case number | Asset named for IRM-45-24 / IRM4524 | IRM60 | Not explicitly stored as property |
Pads
Table
| Pad | Existing function | Existing coordinate | Existing pad / drill | Datasheet pin diameter | Result |
|---|---|---|---|---|---|
| 1 | AC/L | (0, 0) mm | 1.8 mm pad, 1.2 mm drill, rectangular | 1.0 mm pin | Plausible / match |
| 2 | AC/N | (0, 6.75) mm | 1.8 mm pad, 1.2 mm drill, circular | 1.0 mm pin | Plausible / match |
| 3 | -V | (76, 35.75) mm | 3.3 mm pad, 2.2 mm drill, circular | 2.0 mm pin | Plausible / match |
| 4 | +V | (76, 41.25) mm | 3.3 mm pad, 2.2 mm drill, circular | 2.0 mm pin | Plausible / match |
Footprint findings
- Pad numbering aligns with the schematic symbol and datasheet function list: 1=AC/L, 2=AC/N, 3=-V, 4=+V.
- Body outline dimensions match the datasheet PCB mounting style size, 87 x 52 mm.
- Pad drill sizes provide about 0.2 mm clearance over nominal pin diameter: 1.2 mm drill for 1.0 mm pins and 2.2 mm drill for 2.0 mm pins. This is plausible, but should be checked against the target fabricator's finished-hole tolerance.
- The datasheet mechanical drawing is a bottom view. The existing coordinate layout appears consistent, but bottom-view-to-top-footprint mirroring is the main mechanical risk to verify visually against the official drawing before release.
Mismatches / Issues Flagged
Table
| Severity | Item | Details | Recommended action |
|---|---|---|---|
| Medium | Missing pin descriptions | Pins have no explicit descriptions, despite mixing hazardous AC input and DC output. | Add pin descriptions for AC/L, AC/N, -V, and +V. |
| Medium | Pin types are Unspecified | ERC and downstream users get less useful electrical intent. | Set AC/L and AC/N to Power Input; set +V and -V to Power Output or closest supported Flux power type. |
| Low | Datasheet provenance | Datasheet URL is already set to a user-uploaded PDF, not the official Mean Well URL. | Optional: replace or supplement with official URL https://www.meanwell.com/Upload/PDF/IRM-45/IRM-45-SPEC.PDF if preferred for published library provenance. |
| Low | Package/case metadata not explicit | Datasheet case is IRM60, PCB mounting style, 87 x 52 x 29.5 mm, but no explicit package/case property was found in project metadata. | Optional: add package/case metadata if the part property model supports it. |
| Review note | Bottom-view mechanical orientation | Footprint appears correct, but datasheet drawing is bottom view. | Visually overlay / check footprint orientation against official drawing before publishing or production use. |
| Review note | Drill tolerance | Drill clearance over pin diameter is about 0.2 mm. | Confirm with PCB fabricator finished-hole tolerance; enlarge drills if needed for assembly yield. |
Overall Result
No definite pinout or footprint mismatch was found. The part identity, 4-pin schematic symbol, pad numbering, body outline, and nominal pin/drill geometry are consistent with the Mean Well IRM-45 datasheet. The main recommended cleanup is metadata: add pin descriptions, assign meaningful pin types, and optionally point the Datasheet URL at the official Mean Well PDF for provenance.
