The 0022284027: This is the smallest circuit-count member of the Molex KK254 (42375) series: 2 positions, single row, unshrouded.
The unshrouded header leaves the pins exposed — keep-out around the mating face is minimal, but the pins must not contact adjacent components or board edges.
Mates with Molex KK254 crimp receptacle housings (series 2695, 6471, 7880) and IDC ribbon-cable sockets.
Design engineers need full specs (current rating, materials, dimensions) to validate fit.
Buyers need immediate availability to meet production schedules.
Sourcing buyers compare costs across distributors for BOM pricing.
Assembly requires compatible receptacle or housing; missing info causes order errors.
Regulatory compliance is mandatory for many industries (automotive, medical).
Long lead times affect project planning and may force substitute sourcing.
