Summarizing key specifications.

I reviewed the current part metadata, symbol terminals, and footprint pads against the datasheet workflow used for part-project audits, where the datasheet is the source of truth and the pin count must match exactly
Summary Datasheet URL
  • A Datasheet URL is already set in the project, so I did not replace it.
  • Current URL: https://componentsearchengine.com/Datasheets/1/19428-0015.pdf
  • Note: this is a mirror URL, not clearly the canonical Molex PDF URL. The PDF itself references Molex and says to check Molex for the latest information, so it is usable for review, but not obviously the official permanent Molex link.
Key specs from the datasheet
  • Manufacturer: Molex
  • MPN: 19428-0015; the datasheet also shows the ordering code as 0194280015
  • Product family/system: MX150L Industrial Sealed Connector System
  • Description: 5.84 mm pitch MX150L vertical PCB header, dual row, low profile, 12 circuits
  • Orientation: Vertical
  • Termination: Through-hole
  • Circuits loaded: 12
  • Rows: 2
  • Current rating: 18.0 A per contact
  • Voltage rating: 600 V
  • Operating temperature: -40°C to +125°C
  • PCB thickness recommended: 1.60 mm
  • PC tail length: 3.30 mm
  • Features called out: PCB locator, PCB retention, fully shrouded, IP67 rated, 25 mating cycles max
Project property review Looks correct
  • Manufacturer Part Number = 19428-0015
  • Manufacturer Name = Molex
  • Part Type = Connectors
  • Designator Prefix = J
  • Datasheet URL exists
Missing / weak metadata
  • I do not see a Package or Case Code property. For a connector part, this is often less standardized than an IC package, but the project would still benefit from a mechanical/package-style property such as:
    • Vertical Through-Hole, Dual Row, 12 Circuits, 5.84 mm Pitch
  • No electrical summary properties are present for:
    • Max Current = 18 A
    • Operating Temperature = -40°C to +125°C
      These are commonly worth adding when the datasheet provides them
Description mismatch
  • Current project description: “Automotive Connectors 12 Ckt Vert. Header low profile”
  • Datasheet context: MX150L Industrial Sealed Connector System, and it explicitly notes it is not suitable for automotive applications with requirements such as USCAR-2, USCAR-25, GMW3191, etc.
  • So the current description is potentially misleading. “Automotive Connectors” is the biggest metadata issue I found.
Symbol / terminal review
Per the review checklist, terminals should match the datasheet pin count exactly, and terminal properties should be populated from the datasheet where available
What exists now
Schematic terminals present:
  • Circuits: 1 through 12
  • Extra terminal: 13
  • Mechanical terminals: MH1, MH2
Findings
  1. Main pin-count mismatch
    • Datasheet says 12 circuits
    • Your symbol has 13 numbered electrical terminals (1–13)
    • That means terminal 13 appears extra / incorrect
  2. Mechanical features
    • MH1 and MH2 are likely representing the connector’s locator / retention features, which is plausible because the datasheet calls out PCB Locator = Yes and PCB Retention = Yes
    • I would treat these as acceptable mechanical pads/features, not signal circuits
  3. Pin descriptions missing
    • None of the terminals have a meaningful Pin Description
    • For part-quality review, that is incomplete metadata
  4. Pin types all unspecified
    • Every terminal currently has Pin Type = Unspecified
    • For a connector, that’s not fatal, but it is incomplete. If you want stronger ERC behavior, these should usually be set intentionally rather than left unspecified
  5. Designator style
    • Numeric labels for connector contacts are normal and acceptable
    • The problem is not the numbering style itself; it is the presence of pin 13 when the part is a 12-circuit header
Footprint review What matches
  • Footprint contains pads:
    • 1 through 12
    • 13
    • MH1
    • MH2
  • So the footprint is internally consistent with the symbol: both include the extra 13 pad
What does not match the datasheet
  • Same core issue as the symbol:
    • Datasheet: 12 circuits
    • Footprint: 13 numbered electrical pads
  • That makes the footprint appear to have an extra electrical pad 13
What I could not fully verify from current project data
  • Exact drill diameters
  • Pad shapes/sizes
  • Exact row spacing / locator hole geometry
The layout data exposed here shows pad identities but not enough geometry detail to validate the mechanical dimensions against the sales drawing. So I can confirm the pad naming/count mismatch, but not the exact hole pattern dimensions.
Overall mismatch list
  • Project description misleading: says “Automotive Connectors,” while the datasheet positions this in the MX150L Industrial Sealed Connector System and explicitly warns about automotive requirement standards
  • Extra electrical pin/pad 13 in both symbol and footprint
  • Pin descriptions missing on all terminals
  • Pin types left unspecified on all terminals
  • Package/mechanical style metadata missing
  • Optional but useful electrical properties not present: current rating and operating temperature
Recommended corrected summary
A better part description would be:
“12-circuit vertical through-hole PCB header, dual-row 5.84 mm pitch MX150L sealed connector, 18 A/contact, -40°C to +125°C.”
The review guidance specifically recommends descriptions that lead with what the part does, then key specs
If you want, I can next fix the part project by:
  1. removing the extra 13 terminal/pad mapping issue,
  2. updating the description,
  3. filling in missing project properties,
  4. and adding basic pin descriptions/types for the connector contacts.

    Connector Header Panel Mount, Through Hole 12 position 0.230" (5.84mm) The 0194280015 is a wire-to-board rectangular header connector from Molex, part of the MX150L series. It is designed for high-reliability power and signal connections, particularly in automotive and industrial environments. This connector is a 12-position, dual-row, vertical (straight) male header that mounts through the PCB and mates with corresponding cable connectors. It features a sealed design (IP67 rated), making it suitable for harsh conditions such as dust, moisture, and vibration. Key Features Connector Type Wire-to-board male header (vertical / straight) Number of Positions 12 contacts (2 rows) Pitch 5.84 mm terminal pitch ~6.0 mm row spacing High Power Capability Up to ~18 A per contact (application dependent) Voltage rating up to 600V AC/DC Sealed / Rugged Design IP67 rated (dust-tight and waterproof) Suitable for harsh environments Mounting Type Panel mount / through-hole PCB soldering Locking Mechanism Locking ramp + polarization (keying) for secure mating Material & Construction Housing: Glass-filled PBT (UL94 V-0 flame rating) Contacts: Copper alloy with tin plating Durability Designed for automotive-grade reliability Typical mating cycles: ~25 cycles Operating Temperature Approximately -40°C to +125°C #CommonPartsLibrary #Connector #MX150L 19428
