It uses the standard 0.100\" (2.54mm) pitch, which keeps the PCB footprint compatible with a wide range of prototyping grids and production layouts. The right-angle orientation places the pin rows parallel to the board surface, useful for mezzanine stacking or edge-to-edge connections where the mated board sits at 90 degrees. ## Contact Plating and Current Handling The mating contacts carry a gold or GXT™ finish at 30.0 µ\" (0.76 µm) thickness, while the solder tails are tin-plated. The gold on the mating interface supports repeated mating cycles without oxidation buildup, making it a fit for assemblies that see field service or multiple board insertions. Rated at 5 A per contact, the current limit is typical for this pin density and pitch — the limiting factor in practice is the temperature rise in the mated stack, not the contact itself. ## Mechanical and Environmental Fit The through-hole right-angle mounting requires a drilled PCB with plated holes; the 0.120\" (3.05 mm) post length gives enough stand-off for solder fillets on the secondary side. The unshrouded design means there is no plastic wall around the pins, so the mating receptacle must provide its own alignment — this keeps the header footprint compact but demands care during blind mating. The UL94 V-0 rated black housing suits equipment requiring a flammability rating inside an enclosure.","metaTitle":"Amphenol 93939-142HLF BERGSTIK II Header, 42 Pos","metaDescription":"Amphenol 93939-142HLF BERGSTIK II unshrouded header, 42 positions, 0.100\" pitch, through-hole right-angle, 5A, gold/GXT mating finish.","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":"42","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":"Gold or Gold, GXT™","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":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1883","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-142HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 93939-142HLF?","answer":"The 93939-142HLF is rated at 5 A per contact."},{"question":"How many positions does 93939-142HLF have?","answer":"The 93939-142HLF has 42 positions, all loaded, arranged in two rows."},{"question":"Can I use 93939-142HLF as a replacement for 93939-140HLF?","answer":"The 93939-142HLF is a 42-position header, while the 93939-140HLF is a different position count within the same BERGSTIK II series.
