It mates with a wire-to-board receptacle carrying the same 1.25mm pitch, making it a board-side anchor for a locked cable assembly. ## Current rating and wire gauge dependence Voltage rating is 50VAC/DC, which covers low-voltage signal and power distribution in automotive, industrial control, and general-purpose equipment. ## Mating half and harness assembly This header mates with a Micro-LOCK PLUS receptacle housing (series 505433) that accepts crimp terminals for 26-30 AWG wire. The square male pins (0.64mm typical for 1.25mm pitch) wipe the receptacle contacts on insertion.","metaTitle":"5054332421 Molex Micro-Lock PLUS 24-Pin Header SMT 1.25mm","metaDescription":"5054332421 Molex Micro-Lock PLUS 505433 series, 24-position dual-row SMT header, 1.25mm pitch, gold plating, shrouded with latch holder.","metaKeywords":null},"attributes":{"series":"Micro-Lock PLUS 505433","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":"Micro-Lock PLUS 505433","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.049\\\" (1.25mm)","Product Status":"Active","Voltage Rating":"50VAC/DC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.285\\\" (7.25mm)","Ingress Protection":"-","Base Product Number":"505433","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"24","Row Spacing - Mating":"-","Contact Finish - Post":"Gold","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":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"15.0µin (0.38µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.90000","currency":"USD"},{"qty":10,"price":"$2.55500","currency":"USD"},{"qty":100,"price":"$2.03260","currency":"USD"},{"qty":500,"price":"$2.03262","currency":"USD"},{"qty":1000,"price":"$1.68418","currency":"USD"},{"qty":1500,"price":"$1.62610","currency":"USD"},{"qty":2500,"price":"$1.56802","currency":"USD"},{"qty":5000,"price":"$1.50995","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d090feea254e7d4888612e53dfd0a5b6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for Molex 5054332421?","answer":"The mating half is a Micro-Lock PLUS receptacle housing (series 505433) with crimp terminals — same 1.25mm pitch, 24 positions, dual-row.
