The Amphenol FCI 54201-T0806ALF is a 6-circuit, single-row board-to-board header in the BERGSTIK series, built on the standard 0.100-inch (2.54 mm) pitch that has been the default footprint for through-hole and SMT prototyping interconnects for decades. The connector uses an unshrouded square male pin that mates with the matching BERGSTIK receptacle or IDC socket, and its push-pull fastening type relies on friction and pin engagement rather than a locking latch — suited for applications where the board pair is fixed after assembly and not routinely disconnected. Contacts are phosphor bronze with tin plating on both the mating face and the solder tail at 100.0 µin (2.54 µm). The black nylon housing carries a UL94 V-0 flammability rating — the primary compliance attribute listed in the datasheet for this part. Termination is surface-mount solder with a 0.100-inch (2.54 mm) insulation height above the board surface. The part is pick-and-place capable and ships on Tape & Reel, supporting automated assembly flow. Mating pin length is 0.230 inches (5.84 mm), which determines the receptacle socket depth required to ensure full engagement.
The 54201-T0806ALF mates with the matching BERGSTIK receptacle housing or IDC socket that accepts a 0.100-inch pitch, 6-position unshrouded square pin. Verify the socket's insulation depth and contact wipe specification before committing — the 0.230-inch mating pin length must seat fully with no bottoming-out at the housing floor.
The 0.100-inch pitch fits most hobbyist and industrial PCB layouts that can hand-solder or reflow without via-in-pad or micro-via treatment. No current or voltage rating is listed in the datasheet for this part; for new designs, default to the series derating guidelines or confirm with the manufacturer if the circuit exceeds low-level signal duty.
