All 64 positions are loaded, so the circuit count matches the position count exactly. The 110 V rating is the working voltage between adjacent pins; for higher-voltage applications, the 0.100\" pitch provides enough creepage for most low-voltage DC bus work below 60 V. The GXT finish is a palladium-nickel underplate with a gold flash, offering comparable corrosion resistance and wear life to straight gold at a lower cost. The UL94 V-0 rated black insulation housing (0.100\" / 2.54mm insulation height) means the header can be used inside equipment enclosures where a flame-retardant rating is required by safety standards. The overall contact length of 0.410\" (10.41mm) breaks down as 0.190\" (4.83mm) mating length and 0.120\" (3.05mm) solder post — the post length is short enough for single-sided boards but may not fully protrude through thick multilayer PCBs. ## Mating and Board Layout As an unshrouded header, the 79425-164HLF mates with any standard 0.100\" pitch dual-row female socket or IDC receptacle that accepts 0.025\" square pins. The 64-position count and 0.100\" row spacing are common across the BERGSTIK II and many other industry-standard header families, so finding a mating half is straightforward.","metaTitle":"Amphenol FCI 79425-164HLF BERGSTIK II Header, 64 Pos","metaDescription":"79425-164HLF BERGSTIK II unshrouded dual-row male header, 64 positions, 0.100\" pitch, 5A, 110V, gold/GXT plating.
