It is a through-hole solder-terminated board-to-board interconnect with male square pins, gold or Gold, GXT™ plating on the mating surface rated at 30.0 µin (0.76 µm) thickness. The header carries 5 A per circuit at 110 V and uses a phosphor bronze contact base in a black UL94 V-0 rated housing. This is the 31-position fully loaded variant of the 68031 base product number. The 0.100\" (2.54 mm) pitch is the legacy industry standard for through-hole headers — it matches the most common perf-board and prototype footprints. The 31-position count is an odd number, so verify your BOM line calls for exactly 31 circuits; a 30- or 32-position header will not fit the same footprint. The 5 A per-circuit rating is typical for signal and low-power distribution in this pitch class; the 30.0 µ\" gold plating on the mating surface supports repeated mating cycles without contact wear, making this header suitable for applications where the board may be disconnected and reconnected in the field.","metaTitle":"Amphenol FCI BERGSTIK II 68031-131HLF","metaDescription":"68031-131HLF Amphenol FCI BERGSTIK II 31-position unshrouded header, 0.100\" pitch, 5 A, 110 V, gold-plated contacts, 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":"68031-131HLF","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":"31","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":"$1.0220","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/68031-131HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 68031-131HLF?","answer":"The 68031-131HLF uses a 0.100\" (2.54 mm) pitch, which is the standard legacy footprint for through-hole headers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/68031-131HLF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/68031-131HLF when reusing this data.
