It is a Board to Cable/Wire style connector with 3 positions in a single row, spaced at 0.291\" (7.40 mm) pitch. ## 1200 V, latch lock, PEI housing Rated 1200 V, this header is designed for high-voltage power interconnect rather than signal-level duty. The latch lock fastening type secures the mating cable connector against vibration-induced disconnection. The insulation is polyetherimide (PEI) rated UL94 V-0, providing a continuous operating temperature range of -40°C to 150°C — above typical PBT limits. Mating contact finish is gold (3.90 µin), with tin on the solder posts. The gold mating surface supports repeated mate/unmate cycles without oxidation. Lifecycle status is Active with no end-of-life notice. The part is ROHS3 compliant.","metaTitle":"Molex 2018431031 MultiCat Header – 3 Pos, 7.4 mm Pitch","metaDescription":"Molex 2018431031 MultiCat 201843 header, 3 position, 7.40 mm pitch, right-angle through-hole, latch lock, 1200 V rating, PEI housing.","metaKeywords":null},"attributes":{"series":"MultiCat 201843","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"MultiCat 201843","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Aerospace, Automotive, Industrial, Medical","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Latch Lock","Number of Rows":"1","Pitch - Mating":"0.291\\\" (7.40mm)","Product Status":"Active","Voltage Rating":"1200V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Gray","Insulation Height":"0.380\\\" (9.65mm)","Ingress Protection":"-","Base Product Number":"201843","Insulation Material":"Polyetherimide (PEI)","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 ~ 150°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"196.9µin (5.00µm)","Contact Finish Thickness - Mating":"3.90µin (0.099µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.5100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.51000","currency":"USD"},{"qty":10,"price":"$16.87700","currency":"USD"},{"qty":135,"price":"$14.45111","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/19f7382548851554488c5c2e934dac21.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact pitch of Molex 2018431031?","answer":"The mating pitch is 0.291\" (7.40 mm).
