It carries 9 male square pins on the standard 0.100\" (2.54 mm) pitch, through-hole solder termination, with a push-pull mating interface. The 30.0 µin gold or Gold GXT plating on the mating surface is a heavy-duty finish for this class — it handles repeated connect-disconnect cycles in prototyping, test fixtures, or field-service without the contact fretting you'd see with tin. The 0.100\" insulation height keeps the profile low on the board. Rated 5 A per circuit at 110 V, with a UL94 V-0 black glass-filled nylon housing. ## What the Ratings Mean for the Fit The 0.100\" pitch is breadboard-compatible — the footprint is a standard 0.100\" square grid, so board layout is straightforward. The 5 A per circuit rating is typical for a signal header at this density; the real current limit in a dense board is the temperature rise through the single row of pins, not the contact itself. The 30.0 µin gold plating is the key spec for durability: it's rated for hundreds of mating cycles, which matters if this header lives on a programming or test jig. The unshrouded design means no keying or polarization — the mating receptacle's friction fit provides all the retention, so it's best suited for low-vibration internal board-to-board connections where the cable isn't tugged.","metaTitle":"Amphenol FCI 68031-109HLF BERGSTIK II Header, 9 Pos","metaDescription":"Amphenol FCI BERGSTIK II single-row header, 9 positions, 0.100\" (2.54 mm) pitch, through-hole, unshrouded, 30.0 µ\" gold plating, 5 A, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"68031-109HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"68031","Number of Positions":"9","Contact Length - Post":"0.183\\\" (4.65mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.513\\\" (13.03mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4872","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/68031-109HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 68031-109HLF?","answer":"This unshrouded header mates with any standard 0.100\" (2.54 mm) pitch receptacle housing that accepts male square pins.
