I created a detailed part review report with the sourced specs, footprint check, and mismatch list: Part Review - Molex 73100-0207.
Completed the part review and updated the malformed Datasheet URL to the official Molex PDF. The footprint geometry matches the Molex drawing, but I flagged incomplete symbol/pin metadata: all pins are Unspecified, pin descriptions are missing, shield/body pins are not documented, and Mount = Axial conflicts with the through-hole datasheet data.
Open items:
  • Detailed report: Part Review - Molex 73100-0207
  • Frequency rating needs source attribution: legacy datasheet extraction says 4 GHz, current Molex page says 6 GHz.
Suggested next steps:
  1. Update pin descriptions and pin types.
  2. Change Mount metadata to Through Hole.
  3. Optionally revise the symbol to show RF center contact vs shield/body pins distinctly.

Schematic symbol and terminal check
Current schematic symbol implementation uses five independent terminal components numbered 1 through 5. Each terminal currently has:
  • Pin Type: Unspecified
  • No Pin Description
  • No explicit grouping of RF signal versus shield/body/ground legs
Expected electrical interpretation for an SMB PCB jack:

Table


PinExpected descriptionExpected electrical role
1Center contact / RF signalPassive RF signal conductor
2Shield / body / ground legPassive shield/body/ground
3Shield / body / ground legPassive shield/body/ground
4Shield / body / ground legPassive shield/body/ground
5Shield / body / ground legPassive shield/body/ground
Symbol / pin metadata flags
  • Mismatch / incomplete: all five terminals are Unspecified; pin 1 should be identified as the center RF signal contact and pins 2-5 should be identified as shield/body/ground legs.
  • Mismatch / incomplete: no Pin Description properties are populated.
  • Usability issue: the symbol does not communicate coax connector semantics; it appears as five generic terminals rather than one RF center conductor plus shield/body connections.
  • Usability issue: pins 2-5 are not documented as electrically common through the connector body/shield.
Footprint check
Current KiCad footprint asset contains:

Text


pad 1: thru-hole circle at (0, 0), size 1.8 mm, drill 1.2 mm
pad 2: thru-hole circle at (-2.54, -2.54), size 1.8 mm, drill 1.2 mm
pad 3: thru-hole circle at (-2.54, +2.54), size 1.8 mm, drill 1.2 mm
pad 4: thru-hole circle at (+2.54, +2.54), size 1.8 mm, drill 1.2 mm
pad 5: thru-hole circle at (+2.54, -2.54), size 1.8 mm, drill 1.2 mm
fab outline: 6.36 mm square
Official Molex drawing shows:
  • Recommended PCB mounting holes: 5 places
  • Hole diameter: Ø1.20 mm REF
  • Pattern: center hole plus four surrounding holes on a 2.54 mm grid, equivalent to a 5.08 mm × 5.08 mm square around the center
  • Body / footprint reference: 6.36 mm square
Footprint result
  • Matches: pin count, center + four-corner cross pattern, 2.54 mm grid spacing, 1.20 mm drill, and 6.36 mm body/fab outline align with the Molex drawing.
  • Not a mismatch, but note: the 1.8 mm copper pad diameter is a land-pattern design choice; the extracted Molex drawing confirms the 1.20 mm hole but does not explicitly specify copper pad diameter. 1.8 mm gives a plausible 0.30 mm annular ring.
  • No mechanical blocker found: basic through-hole footprint geometry is consistent with the official drawing.
Mismatches / issues to fix
  1. Mount property mismatch: current Mount = Axial; datasheet says Through Hole PCB mounting.
  2. Missing pin descriptions: add center contact / shield-body descriptions for pins 1-5.
  3. Pin Type all Unspecified: change pin 1 and pins 2-5 to an appropriate passive connector/RF signal and shield/ground semantic.
  4. Symbol semantics incomplete: symbol should distinguish RF center conductor from shield/body pins.
  5. Frequency rating source conflict: legacy datasheet extraction reports 4 GHz, while the current Molex product page reports 6 GHz; document source attribution or confirm with Molex before using the higher value.
  • Set Mount to Through Hole if the property schema allows it.
  • Add terminal descriptions:
    • Pin 1: Center contact / RF signal
    • Pins 2-5: Shield / body / ground leg
  • Set pin types to passive-style connector semantics rather than Unspecified.
  • Optionally revise the schematic symbol so the center contact and shield pins are visually distinct.
