Surface-mount termination with a push-pull fastening type. ## 20-Position vs 24- and 26-Position Siblings Within the 55510 series, the 55510-120LF (20 positions) is flanked by the 55510-124LF (24 positions) and 55510-126LF (26 positions). For a BOM requiring exactly 20 circuits, the 55510-120LF is the correct fit; the 24- or 26-position variants will not align with a 20-position footprint. A tape-and-reel variant, 55510-120TRLF, is available for automated pick-and-place assembly — order that suffix if your line runs reels rather than tubes. ## Mating Half and Board Layout Considerations The mated stack height is determined by the header's post length; the receptacle's insulation height is 0.177\" (4.50mm). For board layout, the SMT pads follow the 2.00mm grid pattern; the dual-row footprint is symmetrical, so orientation is keyed by the housing's polarization features.","metaTitle":"55510-120LF Amphenol ICC (FCI) Minitek 2.00mm 20-Pin SMT","metaDescription":"55510-120LF Amphenol ICC (FCI) Minitek 2.00mm 20-position female socket header, SMT, gold 30µin, 2A, 200V.
