The difference: T1LF carries flash gold on the mating contact (no measurable thickness), while this T4LF has a specified 10.0 µinch gold layer. For applications requiring a documented plating thickness — say, a customer print calling out 10 µinch minimum — T4LF is the correct call. Termination is SMD solder — no through-hole, so the board footprint is entirely on the top layer.","metaTitle":"20021521-00020T4LF Amphenol ICC (FCI) Minitek127 20-Pin","metaDescription":"20021521-00020T4LF Amphenol ICC (FCI) Minitek127 1.27mm pitch header, 20 positions, SMD, gold 10µin, UL94 V-0.
