1.2mm Pitch, 6-Circuit Receptacle — What This Connector Is
The Molex 0349006221 is a 1.2mm pitch, single-row receptacle with 6 circuits, as indicated by the description "1.2MM SLDASSYRCPT1X6CPA2 MID DKG". It is supplied in Bulk packaging, meaning loose pieces rather than tape-and-reel, which suits bench-level assembly or repair work where you are wiring one harness at a time. The base product number 034900 groups this receptacle with other variants in the same family, so if you need a different circuit count or orientation, that base number is the place to start looking.
The 1.2mm pitch and 6-circuit count indicate this receptacle mates with a matching 1.2mm pitch header, also 6 positions, single row. The description includes "SLDASSY", suggesting solder assembly tails for board mounting.
