The 5054334271: The 1.25 mm pitch on this 42-position header sets a compact board footprint — 21 contacts per row — which keeps the connector width under 14 mm while still allowing two traces between pads on a standard 1 oz copper PCB.
ROHS3 compliant.
Confirm the wire gauge against the application load before committing the BOM line.
