Compared to the 50-position 79820-150HLF, the 79821-150HLF shares the same 0.100\" (2.54 mm) pitch, dual-row layout, and 30.0 µin gold plating. The difference is the contact length — the 79821-150HLF carries a 0.430\" (10.92 mm) mating pin length versus the 79820's 0.318\" (8.08 mm). That extra 0.112\" (2.84 mm) of pin reach matters when the mating receptacle sits deeper in a shrouded housing or when the board stack-up requires a longer wipe for reliable contact. All 50 positions are loaded; no breakaway option on this variant. The push-pull retention is standard for unshrouded headers — no latch, so the mating force comes from the contact friction alone. In high-vibration environments, a secondary retention method (adhesive or a locking receptacle) is worth planning for.","metaTitle":"Amphenol BERGSTIK II 79821-150HLF, 50-Pos 2.54mm Header","metaDescription":"Amphenol BERGSTIK II 79821-150HLF unshrouded 2-row header, 0.100\" (2.54mm) pitch, 50 positions, through-hole, gold 30.0µin contacts, 5A/110V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-150HLF","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":"79821","Number of Positions":"50","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.730\\\" (18.54mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.430\\\" (10.92mm)","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":"$2.4425","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-150HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pin count of 79821-150HLF?","answer":"The 79821-150HLF has 50 positions, all loaded, arranged in two rows at 0.100\" (2.54 mm) pitch with 0.100\" (2.54 mm) row spacing."},{"question":"Is 79821-150HLF shrouded or unshrouded?","answer":"The 79821-150HLF is unshrouded — it's a bare pin-strip header with no plastic shroud around the pins.
