The surface-mount termination and board guide feature suit it for automated SMT assembly in dense signal interconnects — think server backplanes, telecom line cards, or any mid-board stack where routing density matters more than per-contact current. ## Stack Height Flexibility — One Plug, Four Gaps That means the same BOM line covers multiple board-spacing requirements in a design family — the receptacle height variant, not the plug, sets the gap. For a procurement team, that simplifies inventory to one plug PN across builds with different z-height budgets. ## How It Feeds the SMT Line The board guide helps center the part during placement on a 0.80 mm pitch footprint. ## Active Lifecycle — No LTB Pressure There is no last-time-buy notice or end-of-life horizon on record, so it can be specified into new designs and multi-year production runs without obsolescence risk.","metaTitle":"TE Free Height (FH) 3-5177986-4, 100-pos 0.80mm Plug","metaDescription":"TE Connectivity Free Height (FH) plug, 100 positions, 0.80 mm pitch, dual-row SMT.
