It is a board-to-board interconnect, through-hole soldered, with push-pull fastening. The 0.100\" (2.54mm) pitch and 0.100\" (2.54mm) row spacing are the classic through-hole grid. Any PCB laid out for a standard 0.100\" header accepts this part without a footprint change. ## Mating and Compatibility This is an unshrouded header — it mates with any standard 0.100\" (2.54mm) pitch dual-row IDC socket or crimp receptacle housing that accepts a 66-position, 2-row pattern.","metaTitle":"79425-166HLF BERGSTIK II Header, 66 Pos, 0.100\" Pitch, 5A","metaDescription":"Amphenol FCI 79425-166HLF BERGSTIK II 66-position dual-row unshrouded header, 0.100\" (2.54mm) pitch, 5A, gold-plated contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79425-166HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","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":"0.100\\\" (2.54mm)","Base Product Number":"79425","Number of Positions":"66","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.410\\\" (10.41mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.190\\\" (4.83mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8543","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79425-166HLF/alternatives.json"},"ai":{"faq":[{"question":"What compliance ratings does the 79425-166HLF carry?","answer":"The insulator is rated UL94 V-0 for flame resistance.
