The 54201-G0803LF: Mating pins are 0.230" (5.84mm) long with a 30µin gold finish over phosphor bronze — enough plating for repeated mating cycles in field-service or test-fixture applications without fretting corrosion. The solder posts are tin-plated at 100µin for reliable wetting during reflow.
Bag Packaging vs Tape-and-Reel Siblings
The 54201-G0803LF ships in a bag. If your line runs SMT pick-and-place, the -ALF variant avoids manual loading. Another sibling, 54201-S0803LF, uses a 15µin gold mating finish instead of 30µin. For applications with fewer than 100 mating cycles, the 15µin option saves cost without compromising contact resistance at first mate.
For a build-to-print cable assembly, pair this header with a 3-position crimp receptacle and 20-30 AWG wire terminals — the BOM needs both halves. Black insulation colour provides visual contrast for inspection.
