8-Position Micro-Fit+ Receptacle Housing for Harness Builds
The Molex 2157591008 is an 8-circuit, single-row receptacle housing from the Micro-Fit+ 215759 series, pitched at 3.00 mm.
Eight positions in a single row means a compact footprint on the board or in the harness, but the latch lock is the real tell: it clicks home with an audible snap, and that's your field check that the housing is fully seated. The glow wire compliance (IEC 60695-2-11) means the housing material resists ignition from a hot wire — a requirement for household appliances and certain HVAC gear.
The crimp terminals are the 43030 series female socket contacts, available in tin or gold plating depending on your mating cycle and corrosion requirements. The housing accepts 20-24 AWG wire with the proper crimp tool. No secondary TPA (terminal position assurance) retainer is listed for this housing, so terminal lock is via the primary latch inside the cavity — make sure the crimp pull-off force meets the terminal datasheet spec before you close the harness.
