It uses a 3.20mm pitch and a right-angle through-hole mounting orientation, which means it mates parallel to the PCB plane — a common layout for space-constrained enclosures where the cable exits along the board edge. The 4 A per-circuit rating and 48 VDC voltage rating suit it for low-to-moderate power distribution and signal wiring in industrial control panels, consumer appliances, and automotive interior harnesses where a compact, latch-secured connection is needed. ## Key Features That Drive the Fit The header is fully shrouded with four walls, which protects the male pins from damage during handling and guides the mating receptacle into alignment. A latch holder provides positive retention against vibration and accidental disconnection — no secondary locking hardware needed. The housing is molded from UL94 V-0 thermoplastic, so it meets the flame-rating requirement for equipment inside an enclosure. Tin-on-tin contact plating with 40.0 µin (1.02 µm) on the mating side is a cost-effective choice for applications with a limited number of mating cycles — think one-time assembly or occasional field service, not daily reconnection. ## Sourcing and Lifecycle The 10164521-R181000LF carries an Active lifecycle status from the manufacturer — no end-of-life notice, no last-time-buy window. It is RoHS3 compliant. There is no official second-source or cross-reference on record, so confirm the BOM position count and mating half before committing.","metaTitle":"Amphenol FlexLock 10164521-R181000LF Header, 18 Pos, 3.20mm","metaDescription":"Amphenol FlexLock 10164521-R181000LF board-to-wire header, 18 circuits, 3.20mm pitch, right-angle through-hole, tin contacts rated 4A.","metaKeywords":null},"attributes":{"series":"FlexLock®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Cable/Wire","Series":"FlexLock®","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.126\\\" (3.20mm)","Product Status":"Active","Voltage Rating":"48VDC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.394\\\" (10.00mm)","Ingress Protection":"-","Insulation Material":"Thermoplastic","Number of Positions":"18","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.102\\\" (2.60mm)","Current Rating (Amps)":"4A","Operating Temperature":"-40°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.220\\\" (5.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"40.0µin (1.02µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.41000","currency":"USD"},{"qty":10,"price":"$3.09500","currency":"USD"},{"qty":25,"price":"$2.93160","currency":"USD"},{"qty":50,"price":"$2.86340","currency":"USD"},{"qty":150,"price":"$2.72700","currency":"USD"},{"qty":300,"price":"$2.38613","currency":"USD"},{"qty":450,"price":"$2.31798","currency":"USD"},{"qty":750,"price":"$2.11344","currency":"USD"},{"qty":1050,"price":"$1.97709","currency":"USD"},{"qty":1500,"price":"$1.90891","currency":"USD"},{"qty":3750,"price":"$1.84074","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c98b995a9d3d329344c00f68d082cc02.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 10164521-R181000LF?","answer":"Contact the storefront with your BOM for a same-day quote."},{"question":"Is 10164521-R181000LF shrouded?","answer":"Yes, the header is fully shrouded with four walls, which protects the pins and guides the mating receptacle into alignment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/10164521-R181000LF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/10164521-R181000LF when reusing this data.
