Symbol Cross-Check
Expected
  • A DE-15 high-density female connector should expose 15 signal contacts numbered 1 through 15.
  • Mounting/shell hardware may be represented optionally as shield/mount pins if intended to connect to chassis/ground, but the datasheet’s electrical contacts are 15.
Observed
  • Schematic contains 30 terminal components: two complete duplicated terminal sets, each numbered 1 through 15.
  • The two sub-symbol suffixes are 1731130133_1_1 and 1731130133_1_2.
  • Every terminal has Pin Type: Unspecified.
  • No terminal-level Pin Description values were present.
  • The symbol pin positions are duplicated between the two sub-symbols.
Symbol Findings
  • Mismatch: Symbol exposes 30 signal terminals, but datasheet defines 15 contacts.
  • Mismatch: Pin descriptions are missing/unspecified for all terminals.
  • Likely correction: Use one 15-pin symbol unit for contacts 1–15. If shell/mounting features are electrically modeled, add separate clearly named shield/mount pins rather than duplicating signal contacts.
Footprint Cross-Check
Expected
  • 15 signal through-hole pads, numbered 1–15.
  • 2 mounting/snap-in holes or bracket pads, consistent with Ø3.18 mm and 25.0 mm center spacing.
  • Signal holes should be Ø1.2 mm per datasheet.
Observed
  • Layout contains the correct-looking signal pad set with pads 1–15 arranged on a 3-row high-density D-sub pattern.
  • Layout contains two mount pads labeled 16 and 17.
  • Mount pad size is approximately 3.2004 mm, matching the Ø3.18 mm datasheet hole requirement closely.
  • Signal pad visible size is approximately 1.4986 mm in the main pad set. The tool output did not expose explicit drill/hole size, so the Ø1.2 mm drill could not be confirmed directly from layout metadata.
  • Additional duplicate pad-like nodes for pins 1–15 appear at origin with size approximately 1.6 mm. These appear to correspond to duplicated schematic terminals/sub-symbols, not a clean single footprint pad set.
Footprint Findings
  • Mostly matches: Main footprint pad numbering and mount spacing/features are consistent with the datasheet at a high level.
  • Needs confirmation: Signal drill diameter Ø1.2 mm is not visible in the layout readout, so the imported KiCad footprint should be inspected directly to verify drill size.
  • Potential mismatch/artifact: Duplicate pad nodes for pins 1–15 at origin suggest symbol/footprint import duplication or extra terminal artifacts. These should be cleaned before using the part in a real PCB design.
  1. Remove the duplicate 15-pin symbol unit or consolidate to a single symbol exposing contacts 1–15.
  2. Add terminal descriptions such as Contact 1, Contact 2, … Contact 15, with pin type set to Passive/Unspecified as appropriate for a connector.
  3. Keep mounting pads 16 and 17 only in the footprint unless there is a deliberate schematic-level shell/shield connection requirement.
  4. Verify the KiCad footprint asset has signal hole/drill Ø1.2 mm and mount hole Ø3.18 mm.
  5. Optionally add connector properties: Part Type = Connector, Connector Type = High Density D-Sub, Connector Gender = Female, Connector Positions = 15, Connector Rows = 3, Mount = Through Hole, Current Rating = 3 A, Voltage Rating = 125 V, Operating Temperature = -55 °C to +105 °C.
Overall Verdict
The official datasheet has been attached and the basic metadata now points to Molex/FCT CT09-15S5-L228 / 1731130133. The footprint appears broadly consistent with the datasheet’s 15 contacts plus 2 mounting holes, but the schematic symbol is not clean: it currently exposes two duplicated 15-pin terminal sets and lacks pin descriptions. This should be corrected before the part is used in a design.
