Its 7.40mm pitch and 1200V rating make it a fit for power distribution where standard 2.54mm or 4.2mm headers would risk creepage failure. ## Pitch, voltage, and temperature envelope The 7.40mm pitch is unusually wide for a 3-position header, driven by the 1200V voltage rating. This spacing provides the creepage distance needed for high-voltage isolation without relying on conformal coating. PEI holds its mechanical properties well above the 105°C ceiling of standard PBT housings. ## Contact finish and termination Mating contacts are gold-plated (3.90µin thickness), providing corrosion resistance and reliable contact through repeated mating cycles in corrosive environments. The solder tails are tin-plated (196.9µin) for compatibility with standard lead-free soldering processes. The contact material is copper alloy, and the contact shape is circular — a standard male pin interface that mates with the corresponding MultiCat receptacle terminal. ## Sourcing and lifecycle status The part ships in Tray packaging, suitable for manual or automated pick-and-place assembly.","metaTitle":"Molex 2018431030 MultiCat Header – 3 Pos, 7.4mm Pitch, R/A","metaDescription":"Molex 2018431030 MultiCat 201843 header: 3 circuits, 7.40mm pitch, right-angle through-hole, shrouded 4-wall, latch lock, gold mating finish, 1200V rating","metaKeywords":null},"attributes":{"series":"MultiCat 201843","packageCase":null,"mountingType":null,"rohsStatus":null,"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":"Black","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":"$19.7700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.77000","currency":"USD"},{"qty":10,"price":"$16.47200","currency":"USD"},{"qty":81,"price":"$13.17753","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/39134d0f95549e305b57aab42294e40f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy Molex 2018431030 and how is it quoted?","answer":"The 2018431030 is an active Molex part.
