The locking ramp fastening type keeps the header mated to the receptacle under vibration — a practical requirement for wire-to-board power connections in equipment that sees movement or shock. With 18 positions loaded in a 2-row layout, the dual-row arrangement keeps the connector width manageable while delivering the circuit count needed for multi-wire power distribution. ## Plating and Housing: What the Specs Tell a Harness Builder For a connector that gets mated a few times over its service life, this plating grade is more than adequate. RoHS compliance is confirmed, so it meets the European restriction on hazardous substances for electronic equipment. ## How This Header Compares to the 16-Position Sibling The closest functional alternative within the same base product number is the 10127820-1622LF, which shares the same 4.20mm pitch, 2-row layout, shrouding, locking ramp, tin plating, and UL94 V-0 rating — the only difference is 16 positions instead of 18. If your BOM calls for 18 circuits, this 18-position version is the correct fit. The 16-position sibling saves two positions but requires a board layout change and a different receptacle housing.","metaTitle":"10127820-1822LF Minitek Pwr 4.2 Header 18 Pos 4.2mm Pitch","metaDescription":"Amphenol ICC (FCI) 10127820-1822LF Minitek® Pwr 4.2 header, 18 positions, 2-row, 4.20mm pitch, shrouded, locking ramp, through-hole solder, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Minitek® Pwr 4.2","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Cable/Wire","Series":"Minitek® Pwr 4.2","Package":"Tray","Features":"-","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.165\\\" (4.20mm)","Product Status":"Active","Voltage Rating":"600VAC/DC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.504\\\" (12.80mm)","Ingress Protection":"-","Base Product Number":"10127820","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"18","Row Spacing - Mating":"0.165\\\" (4.20mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.138\\\" (3.50mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0400","priceTiers":[{"qty":1,"price":"$1.04000","currency":"USD"},{"qty":10,"price":"$0.87600","currency":"USD"},{"qty":150,"price":"$0.78633","currency":"USD"},{"qty":450,"price":"$0.64340","currency":"USD"},{"qty":1050,"price":"$0.57190","currency":"USD"},{"qty":4950,"price":"$0.50041","currency":"USD"},{"qty":10050,"price":"$0.47539","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0e7449b4b437b9f082ba9c5697bc9b57.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/10127820-1822LF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 10127820-1822LF and what is the lead time?","answer":"We source 10127820-1822LF through independent distribution against your RFQ.
