0.100" Pitch, 4-Position SMT Header — BERGSTIK® Breakaway
The 95278-401A04LF: Each tin-plated phosphor bronze contact is rated 3 A — typical for signal-level interconnects and low-current distribution inside an enclosure. The push-pull fastening means it relies on the mating receptacle for retention — no locking latch, so vibration resistance depends on the receptacle's own features.
This header terminates by solder to the board surface — no through-hole, no press-fit. The tape-and-reel packaging (cut tape also available) and pick-and-place feature mean it is designed for automated assembly: the vacuum pick point is centred, and the flat top of the insulation body gives a stable nozzle seat.
Sourced through independent distribution channels.
Peer Comparison — Single-Row and Gold-Plated Alternatives
The 95293-401A04LF is a single-row version of this header: same 4 positions, same 0.100" pitch, same tin plating and 3 A rating, but in a single row. If the board layout only needs one row of pins, the single-row part saves board space and reduces the footprint. Gold is the better choice for applications requiring 500+ mating cycles or exposure to humidity, mild corrosives, or frequent field-service reconnection.
