It uses unshrouded square male pins with a through-hole solder termination, making it a general-purpose interconnect for board-to-board or cable-to-board applications where the user snaps the header to the exact position count needed. The 5 A per circuit rating at 110 V, paired with 15.0 µin gold GXT plating on the mating surface, suits it for moderate-current signal and power distribution in controlled environments. ## What the ratings mean for your fit The 0.100\" (2.54 mm) pitch is the de facto standard for prototyping and legacy board layouts — it matches breadboard grids, standard IDC ribbon cable headers, and many development boards. The 72 positions are fully loaded across two rows with a 0.100\" (2.54 mm) row spacing, so the board footprint requires a 2×36 through-hole pattern. The 15.0 µin gold GXT plating on the mating side is the real differentiator here: it supports repeated mating cycles and resists corrosion better than tin, making this header a better fit for field-serviceable assemblies or environments with moderate humidity. The unshrouded, push-pull fastening means there is no polarization key or latch — the mating connector relies on friction fit, so it is best suited for applications where the connection is not subject to high vibration or where a secondary retention method (e.g., wire ties, board-mount clips) is used.","metaTitle":"Amphenol FCI 75844-802-72LF BERGSTIK Header, 72-Pos","metaDescription":"Amphenol FCI BERGSTIK 75844-802-72LF 72-circuit dual-row breakaway header, 0.100\" (2.54mm) pitch, gold GXT 15.0 µin plating, 5A, 110V, 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 or Cable","title":"75844-802-72LF","Series":"BERGSTIK®","Package":"Bulk","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","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":"0.100\\\" (2.54mm)","Base Product Number":"75844","Insulation Material":"Thermoplastic","Number of Positions":"72","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.135\\\" (3.43mm)","Current Rating (Amps)":"5A","Operating Temperature":"-65°C~130°C","Overall Contact Length":"0.465\\\" (11.81mm)","Contact Finish - Mating":"Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2727","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2a3c4564b83d1e0e77f2ae6802960dde.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/75844-802-72LF/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for the 75844-802-72LF?","answer":"As an unshrouded breakaway header, it mates with any standard 0.100\" (2.54 mm) pitch female socket connector, such as a dual-row IDC receptacle or a crimp-style housing that accepts square 0.025\" (0.64 mm) pins.
