Push-pull fastening, no locking latch. That is a signal-level current — fine for logic-level power, I/O, or low-current board interconnects. This header is built for a one-time board-stacking or a low-cycle harness connection, not for frequent field reconnection. The 0.100\" pitch and 0.100\" row spacing set the board footprint — you need a 2x11 grid of 0.040\" plated through-holes on that spacing. The mating pin length is 0.430\" (10.92mm), the post length below the board is 0.200\" (5.08mm), and the overall contact length is 0.730\" (18.54mm). These dimensions matter for stack-height clearance in a mezzanine or parallel-board assembly. Housing is UL94 V-0 rated black thermoplastic. Through-hole termination — rework-friendly if a pin gets bent during assembly.","metaTitle":"Amphenol 79821-422HLF BERGSTIK II Header, 22 Pos","metaDescription":"Amphenol 79821-422HLF BERGSTIK® II unshrouded header, 22 positions, dual-row 0.100\" pitch, through-hole, tin-plated, rated 5 A.","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","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":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"79821","Insulation Material":"-","Number of Positions":"22","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"0.730\\\" (18.54mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.430\\\" (10.92mm)","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":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-422HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pin layout of 79821-422HLF?","answer":"The 79821-422HLF has 22 positions in a 2-row arrangement with all positions loaded — a 2x11 matrix.
