Insulation height of 0.190\" (4.83mm) is the standoff from the board surface to the bottom of the housing. Through-hole termination gives a stronger mechanical anchor than SMT for this pin count, especially under cable strain. The right-angle form factor keeps the connector body low-profile in the z-axis, which matters when the board sits in a tight enclosure. The base product number is 79257; the -434HLF suffix encodes the plating, pin length, and packaging variant.","metaTitle":"79257-434HLF Amphenol ICC BERGSTIK II 34-Pin Header","metaDescription":"79257-434HLF is a 34-position, dual-row, unshrouded header from the BERGSTIK II series. 0.100\" pitch, 3 A rating, 100 µinch tin plating.","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":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"79257","Insulation Material":"-","Number of Positions":"34","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.230\\\" (5.84mm)","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":"$3.4078","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 79257-434HLF RoHS compliant?","answer":"The part is listed as RoHS compliant."},{"question":"What is the pin count of 79257-434HLF?","answer":"34 positions in a dual-row configuration.
