The TE Connectivity 8-106507-2 is a 25-position, 2-row D-Sub receptacle from the AMPLIMITE HD-20 series, shell size DB (B). The mating-side female screwlocks (4-40 thread) secure the mating plug against vibration loosening, which matters in rack-mounted or portable equipment where the connector sees handling.
Rated 6A per contact at 125V, this is a signal-grade D-Sub, not a power interconnect. The current limit is consistent with the 0.406" (10.30mm) backset spacing — enough creepage for 125V but not sized for bus-level current. If your BOM calls for driving a few hundred mA per line (serial, parallel, control signals), the 6A headroom is generous. If you need to pass several amps per pin across multiple positions, derate for temperature rise above 105°C and check the total bundle current against the connector's thermal limits.
Mounting and termination — right-angle solder to the PCB
The 8-106507-2 terminates by soldering the through-hole pins to the PCB. The panel-mount flanges on the mating side accept 4-40 female screwlocks, so the mating plug is fastened with screws rather than relying on friction alone. The backset spacing of 0.406" (10.30mm) sets the distance from the PCB mounting surface to the front of the connector shell — confirm this matches your enclosure cutout depth before layout.
The steel shell is tin-plated for EMI shielding and corrosion resistance. If your application sees frequent connector swaps (test equipment, programming jigs) or operates in a humid or mildly acidic environment, the gold plating is the right choice over a tin-flash alternative.
