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.","metaTitle":"95278-401A04LF BERGSTIK® Header SMT 4-Pos 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) 95278-401A04LF BERGSTIK® board-to-board header, 4 positions, 0.100\" pitch, tin-plated, SMT, UL94 V-0.
