It uses a 0.100\" (2.54 mm) square grid on both pitch and row spacing, which is a standard footprint for prototyping and production PCB layouts. The right-angle through-hole termination places the pin axis parallel to the board, suiting it for mezzanine or perpendicular card stacking where the connector sits at the board edge. ## What the Key Ratings Mean for Your Build Rated 5 A per contact with a 110 V voltage limit. The 5 A figure is per-pin at ambient; in a 58-position header, the total current through the connector is limited by the temperature rise of the housing and the PCB trace width, so a real-world derating applies when all pins are loaded. The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for a few hundred mating cycles in a clean, indoor environment, but tin is susceptible to fretting corrosion under vibration — for high-vibration or frequent-mate applications, a gold-plated sibling from the BergStik II family would be the better call. The UL94 V-0 black housing meets the flammability requirement for equipment inside an enclosure. ## Mating and Termination This unshrouded header mates with any standard 0.100\" pitch, dual-row, square-socket receptacle.","metaTitle":"Amphenol BergStik II 93939-458HLF Header, 58 Pos","metaDescription":"Amphenol BergStik® II board-to-board header, 93939-458HLF, 58 positions, 2 rows, 0.100\" pitch, through-hole right-angle, tin contacts, 5 A.","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":"58","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":"$5.2985","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-458HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 93939-458HLF?","answer":"The 93939-458HLF mates with any standard 0.100\" pitch, dual-row, square-socket female receptacle, such as other BergStik II socket strips. Because it is unshrouded and unpolarized, the mating half must have matching position count and row spacing."},{"question":"Can 93939-458HLF be used in high-vibration environments?","answer":"The tin-plated contacts and push-pull unshrouded design make this header less suited for high-vibration applications. Tin is prone to fretting corrosion under vibration, and there is no locking latch or polarization key to prevent micro-motion. For a vibration-resistant build, consider a gold-plated, shrouded BergStik II variant with a latch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-458HLF","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/93939-458HLF when reusing this data.
