Part Review Mismatch

A

adrian95

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.

flux

I’ll review the part metadata, find and set the official datasheet if missing, then compare symbol/footprint/pin details against the datasheet and record the findings concisely.

flux

The part already has a TDK datasheet URL set, so I’ll use that as the official source and proceed with the cross-check.

Completed the part review and created the detailed report here: Part Review - CCG30-24-15S.
Key finding: the Datasheet URL was already set to the official TDK PDF, but the schematic has a critical pinout mismatch — +VIN and RC are swapped (+VIN should be pin 1, RC should be pin 3). I also flagged incomplete pin descriptions/types and the incorrect logic-IC classification.

Symbol findings
  • The visual signal grouping is reasonable: input/control pins are on the left and output/trim pins are on the right.
  • The schematic symbol pin numbers for +VIN and RC are swapped relative to the TDK-Lambda terminal assignment.
  • All terminal Pin Type values are currently Unspecified; power pins would ideally be typed as power/passive as appropriate.
  • No Pin Description properties are currently present on the terminals; datasheet-derived descriptions should be added for clarity.
Footprint check
Observed footprint data:
  • Footprint source asset: CCG304815S.kicad_mod
  • 6 through-hole circular pads
  • Pad drill: 1.3 mm
  • Pad diameter: 1.95 mm
  • Pad coordinates in source footprint:
    • Pad 1: (0.000, 0.000)
    • Pad 2: (0.000, 7.620)
    • Pad 3: (0.000, 12.700)
    • Pad 4: (20.320, 20.320)
    • Pad 5: (20.320, 10.160)
    • Pad 6: (20.320, 0.000)
  • Body/fab outline: -2.54 to 22.86 mm in both X and Y, matching a 25.4 x 25.4 mm nominal body envelope.
  • Courtyard: approximately -4.6 to 23.86 mm X and -3.54 to 23.86 mm Y.
Datasheet/outline facts:
  • 6 terminals, DIP style
  • Body size: 25.4 x 25.4 mm
  • Pin-row spacing: 20.32 mm
  • Terminal diameter note: 6 x Ø1.0 ±0.1 mm
  • Pin length: approximately 4.1 mm
  • General dimensional tolerance: ±0.5 mm unless otherwise specified
Footprint findings
  • Mechanical size and 20.32 mm row spacing appear broadly consistent with the CCG30-24-xxS outline.
  • Drill 1.3 mm is plausible for Ø1.0 ±0.1 mm pins and leaves clearance.
  • The source footprint name CCG304815S appears to reference a 48 V input variant, but the package appears shared across CCG30 single-output variants; this is not necessarily a mechanical mismatch.
  • Because the schematic currently maps RC to pin 1 and +VIN to pin 3, nets connected through the footprint would land on the wrong physical pads for those two functions even if the footprint pad geometry itself is correct.
Mismatches / issues to flag
  1. Critical pinout mismatch: +VIN and RC are swapped in the schematic terminal numbering.
    • Current: RC = pin 1, +VIN = pin 3.
    • Correct: +VIN = pin 1, RC = pin 3.
  2. Part classification mismatch: current Part Type is Integrated Circuits, and library subtype data shows Logic / AND; this part is a PCB-mount isolated DC-DC converter / power supply module, not a logic IC.
  3. Pin metadata is incomplete: all terminal pin types are Unspecified, and pin descriptions are absent.
  4. Manufacturer naming could be more precise: current TDK; official product page brands the part as TDK-Lambda.
  5. Footprint name references CCG304815S; likely mechanically compatible, but the asset name does not exactly match CCG30-24-15S.
  • Swap schematic terminal pin numbers for +VIN and RC so +VIN is pin 1 and RC is pin 3.
  • Add pin descriptions from the official terminal assignment table.
  • Set more appropriate pin types: input/output power pins as power/passive as supported, RC as input/control, TRM as passive/analog trim.
  • Update part classification away from Integrated Circuits / Logic / AND toward a power supply / DC-DC converter category if available in the project property model.
  • Optionally update Manufacturer Name to TDK-Lambda for exact branding.
  • Optionally rename or annotate the footprint source to make clear that the CCG30 single-output package is shared across voltage variants.
