It uses the industry-standard 0.100\" (2.54 mm) pitch on both the pin-to-pin and row spacing, so the footprint matches legacy PCBs and common prototyping grids. The unshrouded, push-pull design means no locking ramp — the retention comes from the contact interference fit with the mating receptacle. Rated 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts carrying a 100.0 µin tin finish on the mating surface. The 0.100\" pitch and row spacing set the board footprint — a 38-position, 2-row header needs 19 pins per row on a 0.100\" grid, so the board layout requires 38 plated through-holes on a 0.100\" square matrix. The 5 A per circuit rating is typical for a tin-plated header in this size class; the 100.0 µin tin thickness on the mating surface gives a higher number of insertion cycles than a thinner tin plate, but tin contacts are best suited to applications with limited reconnection frequency — think internal harnesses or semi-permanent board stacks rather than field-service connectors. The right-angle orientation means the header body sits at 90° to the board, so the mated height from the PCB surface to the mating interface is around 0.190\" (4.83 mm) plus the mating contact length.","metaTitle":"Amphenol FCI 93939-438HLF BERGSTIK II Header, 38 Pos","metaDescription":"Amphenol FCI BERGSTIK II 93939-438HLF 38-position, 2-row male pin header. 0.100\" pitch, right-angle through-hole, tin-plated contacts, 5 A per circuit at 110 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"93939-438HLF","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":"38","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":"$3.9706","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-438HLF/alternatives.json"},"ai":{"faq":[{"question":"What series does 93939-438HLF belong to?","answer":"93939-438HLF is a member of the Amphenol FCI BERGSTIK II series."},{"question":"What is the listed style of 93939-438HLF?","answer":"The style is Board to Board — the connector is intended for parallel board-to-board stacking rather than wire-to-board harness routing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-438HLF","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/93939-438HLF when reusing this data.
