The power positions use wider blade contacts to handle higher current than the signal pins, so the connector is sized for a power distribution rail alongside dense signal routing. The right-angle orientation and board-edge mounting let the header sit flush with the PCB edge, mating perpendicular to the board for a low-profile daughtercard connection in a backplane or midplane chassis. ## Press-Fit Termination and Board-Edge Mounting Press-fit termination is the key assembly detail here — the compliant pin eyelet deforms as it enters the PCB hole, creating a gas-tight joint without solder. That means no wave-solder or reflow step, which cuts process time and eliminates thermal shock to the board. A mating guide feature helps align the plug during blind-mate assembly in a backplane slot. For a connector that lives in a backplane or power-distribution chassis where the daughtercard may be swapped during service life, that plating thickness means the contact resistance stays stable across dozens of insertion cycles. Gold-palladium adds a harder surface than pure gold, which helps resist fretting corrosion in a vibration environment. The tin-plated alternative common in lower-cost connectors would gall and oxidize under the same duty. ## Flammability and Environmental Compliance ROHS3 compliance is confirmed on record, which covers the full substance restriction including the four phthalates added in the 2015 amendment. No halogen-free or low-halogen claim is stated, but the V-0 rating typically aligns with a halogenated flame retardant system.","metaTitle":"TE Connectivity 1-1892786-8 MINIPAK HDL Header, 33 Pos","metaDescription":"TE Connectivity 1-1892786-8 MINIPAK HDL header, 33 positions (25 signal, 8 power), press-fit termination, right-angle board-edge mount, 30.0µin gold plating","metaKeywords":null},"attributes":{"series":"MINIPAK HDL","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Specialty Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Pitch":"-","Series":"MINIPAK HDL","Package":"Tray","Features":"Mating Guide","Termination":"Press-Fit","Mounting Type":"Board Edge, Through Hole, Right Angle","Connector Type":"Header, Male Pins and Blades","Contact Finish":"Gold or Gold-Palladium","Number of Rows":"-","Product Status":"Active","Voltage Rating":"-","Connector Style":"-","Connector Usage":"-","lifecycle_stage":"unknown","Number of Columns":"-","Base Product Number":"1892786","Number of Positions":"33","Current Rating (Amps)":"-","Operating Temperature":"-","Contact Layout, Typical":"25 Signal, 8 Power","Contact Finish Thickness":"30.0µin (0.76µm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.1700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.17000","currency":"USD"},{"qty":10,"price":"$13.87800","currency":"USD"},{"qty":35,"price":"$13.50886","currency":"USD"},{"qty":70,"price":"$12.84457","currency":"USD"},{"qty":105,"price":"$11.58962","currency":"USD"},{"qty":455,"price":"$11.51578","currency":"USD"},{"qty":945,"price":"$10.03940","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the contact layout of the 1-1892786-8?","answer":"The 33-position header has a hybrid layout: 25 signal contacts and 8 power blades, all positions loaded.
