What I reviewed
Project metadata
  • Project name: SSW-120-01-T-S
  • Manufacturer: Samtec
  • MPN property: SSW-120-01-X-S
  • Designator prefix: J
  • Datasheet URL: https://suddendocs.samtec.com/productspecs/tsw-ssw.pdf
Schematic symbol
  • 20 terminal elements present
  • Terminal designators run 01 → 20
  • All terminals currently use Pin Type = Passive
  • No pin descriptions are populated
Footprint / layout
  • Footprint contains pads 01 → 20
  • Pad count matches the schematic terminal count
  • Numbering appears consistent between symbol and footprint
Key specs found
From the official Samtec SSW/TSW series documentation and Samtec product pages:
  • Series: SSW / TSW
  • Type: Socket strip with PCB tails
  • Pitch: 2.54 mm (0.100")
  • Orientation: Vertical through-hole
  • Positions: 20
  • Rows: Single row
  • Current rating: 4.7 A per pin, one pin powered per row
  • Voltage rating: 465 VAC
  • Operating temperature:
    • Gold plating: -55°C to +125°C
    • Tin plating: -55°C to +105°C
Cross-check results Matches
  • Pin count matches: 20 schematic terminals vs 20 footprint pads
  • Pin numbering matches: both use 01–20
  • Pin type is reasonable: for a passive connector, Passive is appropriate
  • Part family/type is consistent: project clearly represents a Samtec 2.54 mm single-row through-hole socket strip
Mismatches / issues flagged
  1. MPN mismatch
    • The project identity/assets are for SSW-120-01-T-S
    • But the project property says SSW-120-01-X-S
    • X is a wildcard family placeholder, not the exact build variant
    Recommendation: change the MPN property to the exact part if this project is intended to represent the specific loaded variant:
    • SSW-120-01-T-S
  2. Description mismatch / weak description
    • Current description: A Manufacturer recommendations 8.51mm Samtec
    • This is not a clear functional part description
    A better description would be something like:
    • "20-position single-row 2.54 mm through-hole socket strip, vertical Samtec connector"
  3. Pin descriptions are missing
    • The terminals have numbers, but no pin descriptions
    • For this connector, that may be acceptable if each contact is just a numbered passive position
    • Still, if you want a more polished library part, you could add descriptions like:
      • Contact 1
      • Contact 2
      • etc.
  4. Exact mechanical footprint dimensions not fully verified
    • I could verify count and numbering
    • I could not fully confirm hole size / pad diameter / body outline dimensions against the exact Samtec product print from the retrieved spec text alone, because the series spec points to separate product prints for detailed footprint geometry
Bottom line
This part is mostly consistent at the symbol/footprint connectivity level:
  • 20 pins present
  • 20 pads present
  • numbering aligns
The main issue is the MPN property using a wildcard (X) instead of the exact project variant (T). The other notable cleanup item is the poor project description.
If you want, I can next:
  1. update the Manufacturer Part Number to SSW-120-01-T-S, and/or
  2. rewrite the project description into a clean library-ready description.

    20 Position Receptacle Connector 0.100" (2.54mm) Through Hole Tin The SSW-120-01-T-S is a single-row, 20-position female (receptacle) socket strip with a 2.54 mm (0.1") pitch, intended for through-hole PCB mounting. It uses Samtec’s Tiger Buy™ contact system, providing reliable electrical performance and durability for repeated mating cycles. It is commonly used in embedded systems, development boards, and general PCB interconnections, especially where standard 0.1" headers are required. Female header 1x20 2.54mm Key Features Standard 2.54 mm Pitch Industry-standard spacing compatible with most pin headers and prototyping systems 20 Positions, Single Row Ideal for compact signal connections and header interfaces Tiger Buy™ Contact System Provides low insertion force and reliable electrical contact Available in standard or low insertion force variants Through-Hole Mounting Ensures strong mechanical retention and durability on PCBs Tin-Plated Contacts (T option) Cost-effective plating suitable for general-purpose applications High-Speed Capability Supports signals up to ~8 Gbps, depending on application and layout Wide Operating Temperature Range Typically −55 °C to +105 °C, suitable for industrial environments Material Construction Contacts: Phosphor bronze Insulator: High-temperature plastic (e.g., LCP) Versatile Mating Compatibility Mates with common Samtec header series (TSW, MTSW, etc.) and standard 0.025" square posts #CommonPartsLibrary #Connector #SSW-120
