It uses the standard 0.100\" (2.54 mm) pitch for both rows and between rows, making it footprint-compatible with a wide range of legacy board-to-board and wire-to-board applications. Rated at 5 A per contact with a 110 V voltage rating, it is suited for signal-level interconnects rather than power distribution. The mating finish is gold or Gold GXT™ at 30.0 µin (0.76 µm), a robust plating for repeated mating cycles in controlled environments. ## Key Specifications and Fit The header is unshrouded with a push-pull fastening type, meaning it relies on the friction of the mating receptacle for retention — no locking latch. The through-hole solder termination and 0.120\" (3.05 mm) post length suit standard PCB thicknesses. The insulation height of 0.100\" (2.54 mm) keeps the mated profile low. The UL94 V-0 flammability rating confirms the housing meets the flame-retardant requirement for equipment inside an enclosure. The 30.0 µin gold on the mating surface supports a moderate number of mating cycles — adequate for field-serviceable connections but not designed for high-cycle hot-swap duty.","metaTitle":"FCI 79425-120HLF BERGSTIK II Header, 20 Pos, 0.100\" Pitch","metaDescription":"79425-120HLF is an obsolete 20-position dual-row unshrouded header, 0.100\" pitch, 5 A, 110 V, gold plating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK® II","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","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)","Product Status":"Obsolete","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"79425","Insulation Material":"-","Number of Positions":"20","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"-","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","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 - Post":"-","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79425-120HLF/alternatives.json"},"ai":{"faq":[{"question":"Is 79425-120HLF obsolete?","answer":"Yes, 79425-120HLF is officially obsolete per the manufacturer's lifecycle record."},{"question":"What is the replacement for 79425-120HLF?","answer":"No official factory replacement is recorded for 79425-120HLF.
