Part Information Review

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.

Review complete. The part is broadly consistent with the KOA Speer MOS2 51 kΩ ±5% 2 W axial metal-oxide resistor datasheet, but I flagged incomplete metadata: both terminals are Unspecified instead of Passive, and several useful properties are missing (Part Type, Value, Tolerance, Power Rating, operating temp/voltage, package code). Full analysis is in the Part Information Review — MO2C513J project file.

Part Information Review — MO2C513J

Scope

Reviewed available Flux part information, project metadata, schematic terminals/symbol structure, footprint asset, 3D model asset, and the configured datasheet URL.

Datasheet URL status

Datasheet URL is already set: https://www.mouser.com/datasheet/2/219/MOS-16613.pdf
No web search/update was needed because the project already has a datasheet URL.
The linked document is a KOA Speer MOS reduced-size metal oxide power type leaded resistor datasheet.

Table

Field	Current value	Review
Project name	MO2C513J	Matches the requested KOA Speer/Mouser MPN style shown in the project.

Manufacturer Name	KOA Speer	Consistent with datasheet source.
Designator Prefix	R	Correct for resistor.
Datasheet URL	Mouser-hosted KOA Speer PDF	Present.
Part Type	Not present in project properties observed	Should ideally be `Resistor`.
Package or Case Code	Not present in project properties observed	Should ideally describe axial leaded MOS2/MOSX2 body, e.g. `Axial leaded MOS2, L12.0mm x D4.0mm, 28mm pitch footprint`.

Schematic symbol / terminal audit

The part project currently contains two terminal components:

Table

Terminal	Pin Number	Current Pin Type	Expected for resistor	Result
Left terminal	1	Unspecified	Passive	Mismatch / incomplete metadata
Right terminal	2	Unspecified	Passive	Mismatch / incomplete metadata

Symbol findings

Pin count is correct for a two-terminal resistor.
Pin numbers 1 and 2 are appropriate for a non-polar passive resistor.
Both terminal designators are ~ rather than meaningful labels such as 1/2, A/B, or P1/P2; this may be acceptable visually but is not descriptive.
Pin Type is currently Unspecified on both terminals; for a resistor, both should be Passive.
Pin descriptions are not set; suggested short descriptions: Resistor terminal for both pins, or Terminal 1 and Terminal 2.

Footprint audit

Current footprint asset: INDAD2800W80L1200D400.kicad_mod

Observed footprint data:

Through-hole axial resistor footprint.
Pad 1 at (0, 0), pad 2 at (28, 0) → 28.0 mm pad pitch.
Pad diameter: 1.5 mm.
Drill diameter: 1.0 mm.
Body fab outline: x = 8 mm to 20 mm, y = ±2 mm → 12 mm body length × 4 mm body diameter representation.
Courtyard: x = -1 mm to 29 mm, y = ±2.35 mm.
Associated 3D model: MO2C513J.stp.

Footprint vs datasheet

Table

Footprint item	Observed	Datasheet expectation	Result
Pin count / pads	2 pads	2 leads	OK
Body length	12 mm	12.0 ± 1.0 mm	OK
Body diameter / width	4 mm	4.0 ± 0.5 mm	OK
Lead diameter vs drill	0.8 mm lead, 1.0 mm drill	0.8 mm nominal lead	OK; 1.0 mm drill gives clearance
Pad pitch	28.0 mm	lead length 24 mm min.; typical formed pitch not specified for this exact bulk axial configuration	Plausible, but not directly confirmed by datasheet as a required pitch
Footprint naming	`INDAD2800W80L1200D400`	Implies 28 mm pitch, 0.8 mm lead, 12 mm length, 4 mm diameter	Consistent with observed geometry
3D model	Present	Should match 12 × 4 mm axial body	Likely OK, but exact model dimensions were not directly measurable from the available layout data

BOM / library availability note

The BOM tool reports no added parts because this is a part project rather than a normal design containing instances of this part. The project-level part metadata and assets are the relevant source of truth here.

Mismatches / issues flagged

Pin type metadata mismatch: both schematic terminals are Unspecified; they should be Passive for a resistor.
Missing recommended part properties: Part Type, Value, Tolerance, Power Rating, Operating Temperature, Operating Voltage/max working voltage, and Package or Case Code are not present in the observed project properties.
Description is incomplete: current description is accurate but omits the 2 W rating and axial leaded package/body information.
Pin descriptions absent: both terminals lack short descriptions; not critical for a simple resistor, but adding them improves library quality.
Footprint pitch not explicitly validated: 28 mm pitch is mechanically plausible for an axial part with 24 mm minimum lead length, but the datasheet does not appear to define a single mandatory pitch for the bulk axial part.

Recommended fixes

Set both terminal Pin Type values to Passive.
Add or update project properties:
- Part Type: Resistor
- Value: 51 kΩ
- Tolerance: ±5%
- Power Rating: 2 W
- Operating Temperature: -55°C to +200°C
- Operating Voltage: 350 V
- Package or Case Code: Axial leaded MOS2, L12.0mm x D4.0mm, 0.8mm lead, 28mm pitch footprint
Consider updating description to: 51 kΩ ±5% 2 W reduced-size metal oxide axial leaded resistor, MOS2 body 12.0 × 4.0 mm.
