Normalization takeaway

The dataset contains 70 source rows and 70 distinct raw part strings, but normalization reduces the true base-part count to 67. The difference comes from collapsing formatting variants that point to the same underlying device.

  • Prefix differences such as vendor-specific leading codes can create false uniqueness.
  • Package and suffix markers also split identical base parts into multiple raw strings.
  • Only three groups collapsed here, so the catalog is already fairly clean, but the inflation is still visible.
Grouping notes

Manufacturer counts are shown from source rows, while product types are grouped into broader families using keywords and product-name heuristics. That avoids over-fragmentation from inconsistent free-text descriptions.

  • Three rows have no manufacturer value and are grouped as Unknown.
  • Product-type families highlight where the catalog is densest after deduplication.
  • Duplicate examples are listed below so the normalization effect is auditable.
Normalization effect on unique counts
The raw unique list is reduced by three formatting-driven variants after normalization.
Manufacturer breakdown by source rows
Texas Instruments dominates the source catalog, with a smaller Nexperia footprint and a few single-row manufacturers.
Product-type distribution after broad grouping
Grouped horizontal bars compare raw row volume to normalized unique base parts within each product family.
Duplicate groups collapsed by normalization
These raw variants resolve to the same normalized base part number.
