Searching for project data.

I reviewed the part project against the existing Phoenix Contact datasheet URL already set on the project, so no datasheet-property update was needed. For this kind of part-project audit, the key checks are exact pin-count matching and treating the datasheet as the source of truth for pin numbering and metadata
What I found Existing project metadata
Current project-level info:
  • Description: Fixed Terminal Blocks MKDS 2 5/ 3-5 08
  • Manufacturer Name: Phoenix Contact
  • Manufacturer Part Number: 1730405
  • Designator Prefix: J
  • Datasheet URL: already set to the official Phoenix Contact PDF page
Datasheet cross-check
From the official datasheet/product PDF I extracted:
  • Part: Phoenix Contact 1730405
  • Series / family: MKDS 2,5
  • Description: printed circuit board terminal / PCB terminal block
  • Positions / pin count: 3
  • Pitch: 5.08 mm
  • Current rating: 24 A
  • Voltage rating: 400 V nominal
    • also listed: 400 V (III/2), 250 V (III/3), 630 V (II/2)
  • Connection method: screw connection with tension sleeve
  • Wire size: 0.14 mm² to 2.5 mm², AWG 26 to 14
  • Torque: 0.5 to 0.6 Nm
  • Housing material / flammability: PA, UL 94 V0
  • Operating temperature: -40 °C to +105 °C
  • Mechanical: width 16.42 mm, height 21.7 mm, length 11.92 mm, solder pin length 3.7 mm, pin dimensions 1.1 × 0.8 mm, recommended PCB hole diameter 1.4 mm
Symbol audit Good
  • Pin count matches: project has 3 terminal symbols, which matches the datasheet’s 3 positions.
  • Pin numbers match: project terminals are numbered 1, 2, 3, matching the datasheet/contact numbering.
Mismatches / issues
  • Pin names/designators are just 1, 2, 3.
    For a terminal block this is acceptable electrically, but it’s minimal. If you want richer part quality, the terminal labels could stay numeric, but each should have a Pin Description like:
    • Pin 1: Terminal position 1
    • Pin 2: Terminal position 2
    • Pin 3: Terminal position 3
  • Pin Type is Unspecified on all 3 pins.
    For a connector/terminal part, these should not stay unspecified. The part-project sync guidance explicitly calls out setting pin types and descriptions during verification
  • No pin descriptions are present.
    This is the main schematic-symbol metadata gap.
Footprint audit Good
  • The layout contains 3 pads, matching the 3-position datasheet part.
  • Pad numbering is 1, 2, 3, consistent with the symbol and datasheet numbering.
  • Based on the project footprint structure, the footprint is at least topologically correct for a 3-pin terminal block.
Could not fully verify from available geometry output
I could confirm the footprint has the right pad count and numbering, but the current layout readout did not expose exact pad geometry/coordinates, so I could not numerically confirm:
  • 5.08 mm center-to-center pitch
  • 1.4 mm drill diameter
  • exact body-outline dimensions vs datasheet drawing
So the footprint status is:
  • Logical match: yes
  • Full mechanical verification: partially incomplete with the data exposed in this session
Description / property audit Good
  • MPN and Manufacturer are correct.
  • Designator prefix J is appropriate for a connector/terminal block.
  • Datasheet link already points to the official Phoenix Contact source, which is the correct canonical source to keep on the part
Missing / weak metadata
Compared with the datasheet, the project is missing several useful part properties:
  • Part Type: should be something like Connector
  • Package or Case Code: should reflect the connector family/package style, e.g. MKDS 2,5/ 3-5,08
  • Max Current: 24 A
  • Operating Temperature: -40°C to +105°C
  • Potentially Implementation Details for:
    • screw connection with tension sleeve
    • conductor range 0.14–2.5 mm²
    • tightening torque 0.5–0.6 Nm
    • PCB hole diameter 1.4 mm
The description is also technically understandable, but it could be improved to a clearer library-facing description. The part-project sync guidance recommends descriptions that start with what the part does, then key specs
A better description would be:
  • “3-position PCB terminal block, 5.08 mm pitch, 24 A, 400 V, screw clamp”
Summary of mismatches / flags Confirmed matches
  • MPN matches datasheet
  • Manufacturer matches datasheet
  • Pin count matches datasheet
  • Pin numbering matches datasheet
  • Datasheet URL already set and official
  • Designator prefix is appropriate
Confirmed issues
  1. All 3 pins have Pin Type = Unspecified
  2. No Pin Description properties
  3. Description is present but not ideal for a reusable part listing
  4. Important project metadata is missing:
    • Part Type
    • Package/Case Code
    • Max Current
    • Operating Temperature
    • optional implementation/mechanical details
Not fully verified
  1. Footprint mechanical dimensions
    I could not fully confirm drill/pad geometry and exact 5.08 mm pitch from the exposed layout data, only that the footprint has 3 correctly numbered pads.
Recommended next fixes
  1. Set Part Type = Connector
  2. Improve the project description
  3. Add:
    • Package or Case Code = MKDS 2,5/ 3-5,08
    • Max Current = 24 A
    • Operating Temperature = -40°C to +105°C
  4. Set each terminal’s:
    • Pin Type
    • Pin Description
If you want, I can apply those metadata and pin-property fixes now.
