The 09552666820741 is a 15-position D-Sub plug from Amphenol FCI, built for board-edge signal I/O where a standard-density DB15 footprint is needed.
SMT Termination vs Through-Hole — What It Changes
The key difference between this SMT plug and a traditional through-hole D-Sub like the 09652696711 is the board assembly process. The trade-off is mechanical: the SMT solder joints carry the full insertion and extraction force of the mating cycle, so the board must have adequate pad adhesion and the 4-40 screwlocks (mating side, female) should be tightened to take the shear load off the contacts. The through-hole variant has stronger board retention from the tails, but adds a secondary soldering operation.
Mating and Hardware Compatibility
This plug mates with a standard DB15 receptacle — the mating half is the 09552156612741, a 15-position female D-Sub with the same shell size (2, DA, A) and 4-40 thread hardware. The flange feature on this plug is a female screwlock on the mating side, so the mating receptacle needs male screwlocks (housing/shell type) or a 4-40 jack-screw.
