Compared to the 26-position sibling (77313-118-26LF) or the 16-position (77313-118-16LF), the only difference is the number of positions — all other specs (pitch, plating, current, material, UL94 V-0 rating) are identical. This means the 40-position version is the largest in this subgroup, and the breakaway feature lets you depopulate it for lower-count BOMs without requalifying a new part number. It is RoHS compliant.","metaTitle":"77313-118-40LF Amphenol ICC (FCI) BERGSTIK® Pin Header 40","metaDescription":"77313-118-40LF Amphenol ICC (FCI) BERGSTIK® header, 40 positions, 2.54mm pitch, 3A, gold plating, RoHS.
