Unshrouded header for board-level power distribution
The 1-1546214-4 is the 14-position member of TE's Buchanan unshrouded pin header line, built for through-hole vertical mounting on a 5.00 mm pitch. Tin-plated mating finish on copper alloy contacts keeps the per-circuit cost low for power and signal interconnects where the mating cycle count stays under a few dozen. The PA66 housing carries a UL94 V-0 flammability rating and the assembly runs from -40°C to 110°C.
What the 5.00 mm pitch and unshrouded format mean for the board layout
The 5.00 mm pitch leaves generous trace routing space between pins on a standard FR-4 board — no need for tight neck-downs or extra layers to fan out the 14 circuits. The unshrouded header exposes the pins for direct probing or manual wiring, but offers no keying or polarization against a misaligned mate. Single-level construction with 14 positions per level keeps the board footprint compact in one axis. Through-hole solder termination provides a mechanically robust joint for wire-to-board connections that see occasional handling.
