Frequently asked questions
How do I source the 77311-127-28LF?
Quoted to order against the BOM quantity through independent distribution — availability and current pricing are confirmed at quote time, not published on-screen.
What connector mates with the BERGSTIK 77311-127-28LF?
The matching 28-position single-row BERGSTIK receptacle or IDC socket in the same 2.54 mm pitch family accepts the 0.260 inch (6.60 mm) mating pin length; confirm the housing keying and mounting footprint match your board layout.
What is the difference between gold and tin contact plating on this header?
Gold flash (30.0 µin / 0.76 µm) on the mating face governs low-resistance contact and cycle life; tin (78.7 µin / 2.00 µm) on the solder tail provides the wettable finish for reliable through-hole solder termination — these are separate finish zones, not competing options.
