It uses the standard 0.100\" (2.54 mm) pitch on both the pin-to-pin and row-to-row spacing, making it a drop-in fit for any board layout designed around the ubiquitous 0.100\" grid. Rated 5 A per circuit at 110 V, it handles moderate signal and low-power distribution on a single connector. The tin-plated phosphor bronze contacts — 100.0 µin on the mating surface — are suited for applications where the connector is mated infrequently or in a controlled environment, as tin-on-tin interfaces are more prone to fretting corrosion under vibration than gold systems. The right-angle through-hole termination places the pins parallel to the PCB, useful for board-edge or mezzanine connections where the cable exits along the board plane. ## Mounting and Mechanical Fit The 93939-448HLF mounts through-hole, right-angle, with a solder termination. The unshrouded design means there is no plastic wall around the pins — the mating receptacle housing provides the polarization and keying. The 0.190\" (4.83 mm) insulation height and 0.160\" (4.06 mm) mating pin length set the standoff from the board. The 0.120\" (3.05 mm) post length is the solder tail dimension for the through-hole joint. The push-pull fastening type means no locking latch; retention relies on the friction of the mating contact interface. The UL94 V-0 black housing meets the flammability requirement for equipment inside an enclosure.","metaTitle":"Amphenol FCI BergStik II 93939-448HLF, 48-Pin 2.54mm Header","metaDescription":"Amphenol FCI BergStik II 93939-448HLF, 48-position dual-row unshrouded header, 0.100\" pitch, 5 A, 110 V, tin-plated contacts, right-angle through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK® II","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","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)","Product Status":"Active","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"93939","Insulation Material":"-","Number of Positions":"48","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","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 - Post":"-","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6125","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-448HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and number of positions of 93939-448HLF?","answer":"The 93939-448HLF has 48 positions on a 0.100\" (2.54 mm) pitch, dual-row, with the same 0.100\" row spacing.
