It is a board-to-board interconnect, though the unshrouded pins also mate with standard IDC receptacles for wire-to-board harnesses. Tin-plated contacts rated 5 A per circuit at 110 V, with a 100.0 µ\" (2.54 µm) tin mating finish — a heavy plating that handles moderate mating cycles without fretting in low-vibration environments. ## Footprint and fit 22 positions loaded in two rows at 0.100\" (2.54 mm) row spacing — 11 pins per row. The 0.100\" pitch matches the legacy 2.54 mm grid, so the board footprint lines up with standard DIP or header patterns. The 0.120\" (3.05 mm) solder post length is typical for a 1.6 mm PCB — the post protrudes through the board for a clean solder fillet. ## Current and voltage headroom The 110 V rating gives enough creepage for the 0.100\" pitch without forcing a wider board footprint. For a typical 22-circuit header carrying 2–3 A per pin, the temperature rise stays well within the housing limits. The 100.0 µ\" tin mating finish is thicker than the common 30–50 µ\" tin flash, so it resists wear through repeated insertion cycles better than a thinner coating. Active lifecycle status — the 93939-422HLF is still in regular production with no end-of-life notice on record.","metaTitle":"93939-422HLF BERGSTIK II Header, 22-Pin, 0.100\" Pitch, 5A","metaDescription":"Amphenol FCI BERGSTIK II 93939-422HLF, 22-circuit dual-row unshrouded header, 0.100\" pitch, 5A, 110V, tin-plated, 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":"93939-422HLF","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":"22","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":"$0.8889","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-422HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the 93939-422HLF's connector style?","answer":"The 93939-422HLF is listed as Board to Board style — a dual-row male header designed for board-to-board signal and low-power interconnect."},{"question":"What is the 93939-422HLF's series?","answer":"The 93939-422HLF is a member of the Amphenol FCI BERGSTIK II series — a 0.100-inch pitch, square-pin dual-row header family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-422HLF","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/93939-422HLF when reusing this data.
