Tin plating on both the mating surface and the solder tails keeps the cost down for applications where the connector is mated infrequently — the 100.0 µin (2.54 µm) finish on the mating side provides enough thickness for reliable contact in moderate environments without the expense of gold. The 5 A figure is per-contact, so a fully loaded 44-position connector can carry 5 A on every pin simultaneously only if the total current stays within the temperature rise limits of the housing — in practice, derate when populating adjacent circuits at full load. The 110 V rating provides enough headroom for typical logic-level and low-voltage DC rails. Through-hole, right-angle termination: the 0.120\" (3.05 mm) solder post length is sized for standard PCB thicknesses around 0.062\" (1.6 mm). The 0.190\" (4.83 mm) insulation height gives clearance for routing traces under the body.","metaTitle":"Amphenol BERGSTIK II 93939-444HLF, 44-pos Header, 5 A","metaDescription":"Amphenol 93939-444HLF BERGSTIK II unshrouded dual-row header, 44 positions, 0.100\" pitch, right-angle through-hole, tin contacts, 5 A, 110 V, 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":"93939-444HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Base Product Number":"93939","Number of Positions":"44","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.160\\\" (4.06mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9526","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-444HLF/alternatives.json"},"ai":{"faq":[{"question":"What are the mating connectors for 93939-444HLF?","answer":"This unshrouded header mates with standard 0.100\" pitch dual-row receptacle housings and IDC sockets that accept square 0.025\" (0.64 mm) pins.
