Mated stacking height is 11.1 mm, so budget that z-height in the enclosure layout. ## Contact plating and current derating Tin is a workhorse finish for moderate mating-cycle applications — expect a few dozen cycles before wear-through, which is fine for harnesses assembled once and mated infrequently in the field. In practice, for 22-24 AWG wire, derate to around 3 A per contact at 85°C ambient; the 105°C ceiling is the absolute limit. The part is ROHS3 compliant. ## Mating half and board footprint This header mates with a Micro-Lock PLUS 505575 series receptacle housing (sold separately). Confirm the mating receptacle part number matches the 8-circuit count and 2.00 mm pitch before committing.","metaTitle":"Molex 5055750871 Micro-Lock PLUS Header, 8 Pos, 2 mm, SMT","metaDescription":"Molex 5055750871 Micro-Lock PLUS 505575 header, 8 positions, 2.00 mm pitch, SMT, locking ramp, tin plating, -40°C to 105°C, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Micro-Lock PLUS 505575","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 505575","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":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.079\\\" (2.00mm)","Product Status":"Active","Voltage Rating":"250VAC/DC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.339\\\" (8.61mm)","Ingress Protection":"-","Base Product Number":"505575","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"8","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":"11.1mm","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":"39.4µin (1.00µm)","Contact Finish Thickness - Mating":"39.4µin (1.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.53000","currency":"USD"},{"qty":10,"price":"$1.30200","currency":"USD"},{"qty":100,"price":"$1.07560","currency":"USD"},{"qty":600,"price":"$1.07560","currency":"USD"},{"qty":1200,"price":"$0.84916","currency":"USD"},{"qty":1800,"price":"$0.82085","currency":"USD"},{"qty":3000,"price":"$0.79255","currency":"USD"},{"qty":6000,"price":"$0.75292","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6b234cda92c6b00a8464203902a117c9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of Molex 5055750871?","answer":"The mating pitch is 2.00 mm (0.079 inches).
