DF5A-6DP-5DSA - 5mm Pitch 6-Pin Dual Row Through-Hole Header | Hirose

The Hirose DF5A-6DP-5DSA is a 6-position (2 rows × 3 contacts) through-hole male pin header from the Hirose DF5 series, designed as a miniature potting connector for secondary power supply applications. It uses a 5.0 mm pitch contact geometry and stands 22.5 mm above the PCB mounting surface, with a maximum potting allowance of 9 mm, making it suitable for encapsulated power modules. The header accepts the DF5 series crimp socket housings and is supplied in straight (vertical) orientation with a tin-plated contact finish. A pin header is a single-row or multi-row array of male contacts pressed or soldered through a printed circuit board, providing a polarized, removable mating interface for wire-to-board and board-to-board power or signal connections. Within the broader interconnect hierarchy, pin headers sit under rectangular board connectors (Headers, Male Pins), which in turn belong to the wire-to-board connector family used throughout power management, industrial control, and appliance electronics. Pin headers are the lowest-cost method to bring power rails or low-speed signals off a sealed PCB, and the potting-friendly DF5 series specifically targets encapsulated power supplies and motor-drive modules. Key features include a 5.0 mm contact pitch, 6 contacts arranged in two rows of three, tin-plated brass contacts for solderability and corrosion resistance, and a glass-fiber reinforced thermoplastic insulator rated for reflow soldering and potting compound exposure. The mating interface accepts standard DF5 series receptacle housings with crimp-terminated discrete wire or ribbon cable. The connector is rated for up to 8 A per circuit at 500 V AC/DC depending on wire gauge. The DF5A-6DP-5DSA uses a polarized housing with positive locking latches that engage with the corresponding crimp socket housing. The 5 mm pitch is larger than signal-density headers (typically 2.54 mm), making this part optimized for power applications where creepage, clearance, and current-carrying capacity take priority over contact density. The straight-through mount orientation enables wave soldering during PCB assembly. Typical applications include secondary-side power supplies in industrial equipment, encapsulated power modules, HVAC control boards, appliance motor controllers, and LED lighting drivers. The 5 mm geometry also suits battery management wiring harnesses where larger gauge conductors (AWG 18 to AWG 22) are used for current-carrying capability rather than fine-pitch signal routing. When designing with this part, ensure the PCB through-hole pad diameter matches the 1.5 mm nominal pin diameter, maintain 22.5 mm clearance above the board for mating receptacle engagement, and confirm the maximum potting compound depth (9 mm) is not exceeded when the header is potted inside an enclosure.
