If the BOM calls for 6 circuits, the 77311-818-06LF is a direct footprint match; if 2, the 77311-818-02LF fits the same pattern. No shrouding or keying — the header is a bare pin strip, so the mating receptacle must have its own polarization guide. The push-pull fastening means the connector pair separates under cable tension without a secondary latch, which is typical for internal board-stacking or low-vibration environments. The 0.230\" mating pin length engages standard box-type receptacles with full contact wipe. Termination is solder to through-hole pads — the 0.120\" post length fits a 1.6mm (0.063\") board thickness with enough protrusion for a visible solder fillet.","metaTitle":"77311-818-04LF Amphenol ICC BERGSTIK® Header 4 Pos 2.54mm","metaDescription":"77311-818-04LF BERGSTIK® unshrouded header, 4 positions, 0.100\" pitch, 3 A, gold/GXT™ mating finish.
