Analyzing the PCB layout.

Looking for "Exact manufacturer part number, product description, series, number of positions, number of rows, pitch, mounting type, contact type, rated current, rated voltage, and color." in pcb-header-mcv-05-2-g-254-p20-thr-r24-1821397?type=pdf

Identifying footprint issues.

Reviewing project details.

I reviewed the part project against the official Phoenix Contact PDF. The project already has a Datasheet URL set, so no web search or property update was needed. The datasheet-sync workflow says to treat the datasheet as the single source of truth and verify exact pin count, metadata, and terminal mapping

What I found in the part project

AreaObservation
Schematic symbolThere are 4 terminal components labeled 1, 2, 3, 4, each with Pin Type: Unspecified and pin numbers 1-4.
FootprintThe attached footprint 1821397.kicad_mod contains 4 through-hole pads numbered 1, 2, 3, 4.
3D modelA STEP model is attached.
Pin metadataNo pin descriptions are populated; pin types are not set.

Mismatches to flag

SeverityIssueWhy it matters
HighSymbol has 4 pins, datasheet says 2 positionsThe part project does not match the real connector pin count.
HighFootprint has 4 pads, datasheet indicates 2 contactsPCB land pattern appears wrong for this exact variant.
MediumManufacturer Part Number is stored as 1821397 onlyUsable, but the exact Phoenix type string is MCV 0,5/ 2-G-2,54 P20 THR R24.
MediumPin types are all UnspecifiedFor a connector part, these should be intentionally classified rather than left blank.
LowPin descriptions are missingEven short labels like "Position 1" and "Position 2" would make the part cleaner.
LowMount property says SolderMore precise would be THR soldering.
Pin cross-check
The datasheet indicates only pin 1 and pin 2, with no inherent polarity and no distinct electrical function between them. They are simply the two connector positions. The current project instead models pins 1-4, which conflicts with the datasheet.

Recommended corrections

PriorityFix
1Replace the current 4-pin symbol with a 2-pin symbol matching positions 1 and 2 only.
2Replace the current 4-pad footprint with the correct 2-position THR footprint for item 1821397.
3Set pin types for the two contacts to a connector-appropriate type, rather than Unspecified.
4Add short pin descriptions such as Position 1 and Position 2.
5Optionally refine metadata: keep item number 1821397, but also ensure the full ordering string MCV 0,5/ 2-G-2,54 P20 THR R24 is preserved in description/properties.
Bottom line: the metadata is mostly close, but the symbol and footprint are clearly for a 4-position part, not this 2-position Phoenix Contact header.
