It uses a standard 0.100\" (2.54 mm) square grid on both pitch and row spacing, making it footprint-compatible with a wide range of industry-standard receptacles. The male pins are square, phosphor bronze with a 30.0 µin gold or GXT™ mating finish, rated for 5 A per contact at 110 V. The through-hole solder termination and 0.120\" post length suit it for standard PCB thicknesses. ## Key Specs and What They Mean for the Fit The 24 positions loaded across two rows at 0.100\" pitch define the PCB footprint — a 24-pin, dual-row layout with 0.100\" row spacing. The unshrouded push-pull design means there is no polarization key or locking latch; the header relies on the mating receptacle's internal retention. The 30.0 µin gold on the mating surface is the feature that governs real-world duty: it supports repeated mating cycles and resists corrosion in industrial or field-service environments better than a tin-plated equivalent. The UL94 V-0 rated black housing meets the flame-retardant requirement for equipment inside an enclosure. ## Mating and Termination This unshrouded header mates with standard 0.100\" pitch box-style receptacles, including IDC sockets and crimp-housing receptacles from the BergStik and similar families. The through-hole solder termination requires no special tooling beyond a wave or hand solder process. The 0.250\" mating length provides sufficient engagement depth for most standard receptacles.","metaTitle":"FCI 86503-124HLF BergStik II Header, 24 Pos, 0.100\" Pitch","metaDescription":"FCI 86503-124HLF BergStik II unshrouded header, 24 positions, 2 rows, 0.100\" pitch, 5 A, 110 V, 30.0 µin gold plating.
