The Molex 87052-416HLF is a 16-position, 2-row unshrouded male pin header from the BERGSTIK II series, on the standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect, through-hole soldered, with tin plating on both the mating surface and the solder tails. The 5 A per-circuit rating and 110 V voltage rating suit it for general-purpose signal and light power distribution on a PCB — think backplane card edges, peripheral I/O, or internal wiring where the connector is mated once and left in place.
What the ratings mean for the fit
The 0.100" pitch and 0.100" row spacing are the industry-standard 2.54 mm grid — the footprint is a drop-in for any legacy 0.100" header layout. The 16 positions loaded all 16 pins, so the BOM circuit count matches the position count exactly. The tin-on-tin contact finish (100.0 µin on the mating side) is rated for a limited number of mating cycles — this is a cost-optimized signal connector for permanent or infrequent-disconnect applications, not a high-cycle field-service interface. The unshrouded design means no polarization keying: the mating receptacle must be correctly oriented by the board layout or harness routing.
