25-Position DB-25 SMT D-Sub Plug
The HARTING 09553296812741 is a DB-25 (B shell size) D-sub plug with 25 male pins arranged in two rows. It terminates via surface-mount solder pads, making it a fit for pick-and-place assembly on boards where a through-hole D-sub would crowd the opposite side. The black LCP housing includes integral board guides to align the part during reflow, and the steel shell carries a 4-40 threaded insert on the flange for mating with standard D-sub hardware.
What the 5 A and Gold Plating Mean for Signal Duty
For a connector that may see field-service unplug/replug cycles, that gold interface matters more than the headline current number.
SMT Termination and Board Layout Considerations
This is a surface-mount D-sub — less common than the through-hole version, but it saves drilling the PCB and lets you run traces on the layer directly under the connector body. The board guide feature (molded into the housing) helps align the part to the footprint pads during reflow, reducing tombstoning on a part with 25 solder joints. The 4-40 threaded shell flange provides mechanical retention to the mating receptacle or a metal bracket; without it, the SMT solder joints alone would carry the full cable strain. The Tape & Reel packaging suits automated assembly lines feeding a pick-and-place head.
It is not a last-time-buy or phase-out line item.
