It carries tin-plated mating contacts, a 0.118\" (3.00mm) pitch, and a locking ramp fastening system that holds the mated pair against vibration. The header mounts surface-mount right-angle and includes solder retention features for reflow stability. Rated 600VAC/DC, the housing is black LCP with UL94 V-0 flammability rating, operating from -40°C to 105°C. ## Pitch, footprint, and routing density The 3.00mm pitch and single-row layout keep the board footprint narrow — useful for tight edge-routing where a dual-row header would crowd adjacent traces. The 4-wall shrouding protects the pins during handling and guides the mating receptacle. ## Mating and termination Termination is solder to the PCB — the SMT right-angle orientation places the pin axis parallel to the board surface. The locking ramp engages with the matching receptacle latch; the solder retention feature holds the part in place during reflow.","metaTitle":"Molex 2189890300 Header, 3-Pos 3.00mm Pitch, SMT RA","metaDescription":"Molex Micro-Fit+ 2189890300 header: 3 circuits, 0.118\" (3.00mm) pitch, single row, SMT right-angle, tin mating contacts, locking ramp, shrouded.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Micro-Fit+ 218989","Package":"Tape & Reel (TR)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.118\\\" (3.00mm)","Product Status":"Active","Voltage Rating":"600VAC/DC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.173\\\" (4.40mm)","Ingress Protection":"-","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","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":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8550","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9d74f29a35bb0a7b8314bdd509dd1d7e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2189890300/alternatives.json"},"ai":{"faq":[{"question":"What is the listed style of 2189890300?","answer":"The listed style is Board to Cable/Wire, meaning it is a board-mounted header designed to mate with a wire-to-board receptacle housing."},{"question":"What series is 2189890300 part of?","answer":"It is part of the Molex Micro-Fit+ 218989 series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/2189890300","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/molex/2189890300 when reusing this data.
