It uses the standard 0.100" (2.54 mm) pitch on both rows and between rows, making it a direct footprint match for any 0.100" grid dual-row receptacle. Rated 5 A per circuit at 110 V, the 86503-426HLF carries enough current for most signal and moderate-power duties on a 0.100" pitch. The UL94 V-0 black insulation height sits at 0.100" (2.54 mm) above the board, which is the standard low-profile for this class of unshrouded header.
Footprint and layout
The 0.100" (2.54 mm) pitch and 0.100" row spacing define a 13-pin-per-side dual-row layout. The overall contact length is 0.470" (11.94 mm), split into a 0.250" (6.35 mm) mating pin and a 0.120" (3.05 mm) solder tail. That 0.120" post length is a standard through-hole length for a 0.062" PCB — it protrudes enough for a clean solder fillet without bottoming out in a plated hole.
