The mating contacts carry 30.0 µ\" (0.76 µm) gold plating over the phosphor bronze base, a thickness that supports repeated mating cycles without exposing the base metal to oxidation. The post (solder tail) side is tin-plated for a reliable solder joint into the plated through-hole. ## Mating and Fit The push-pull retention relies on contact interference fit rather than a latch.","metaTitle":"Amphenol 93939-154HLF BERGSTIK II Header, 54-Pos","metaDescription":"Amphenol BERGSTIK II 93939-154HLF unshrouded header, 54 positions, 2 rows, 0.100\" pitch, 5 A, 110 V, gold-plated mating contacts.","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":"54","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":"$5.3224","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-154HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 93939-154HLF?","answer":"The 93939-154HLF uses a 0.100\" (2.54 mm) pitch for both the pin spacing and the row-to-row spacing."},{"question":"What are the specifications of the 93939-154HLF?","answer":"The 93939-154HLF is a 54-position, dual-row, unshrouded header with a 0.100\" pitch.
