The 10146997-04000LF is a 4-position, 2-row right-angle header from the Minitek® Pwr 5.7 series, designed for board-to-cable/wire connections. The 5.70 mm pitch and matching row spacing give it room to carry moderate power per contact — think power distribution inside a telecom shelf or a medical device PSU.
Right-angle mounting and board fit
That orientation saves vertical space inside an enclosure and simplifies cable routing to a backplane or panel exit. Factor that into your component keep-out when placing nearby tall parts.
The header accepts the Minitek Pwr 5.7 cable-side receptacle (not included). Gold-to-gold contact at the mating interface keeps resistance stable over repeated mate cycles; the tin post is for the solder joint.
The closest functional sibling is 10146997-08000LF — same series, same 5.70 mm pitch, same right-angle through-hole mounting, same gold mating finish. If your BOM calls for 4 positions, the 8-position part won't fit without a board redesign.
