The 2029265-2: Glow wire compliance (per IEC 60695-2-11) means the housing material passes the 850 °C glow-wire test without ignition — a standard requirement for lighting and household appliance connectors.
Rated 9 A at 600 VAC – Where That Current Goes
9 A per circuit at 600 VAC with tin-plated contacts — the tin finish limits mating cycles to about 25–30 before contact resistance starts climbing, so this header suits semi-permanent connections in junction boxes or lighting fixtures where you mate once and leave it. The 4.20 mm pitch and 0.165" row spacing give enough room for 18–22 AWG wire in the mating receptacle without crowding the board traces.
ROHS3 compliant per the manufacturer's declaration.
How This Compares to the 20-Position Sibling
The 20-position variant 4-1775099-7 shares the same 4.20 mm pitch, 9 A rating, tin contacts, locking ramp, and UL94 V-0 housing — the only difference is circuit count. If your BOM needs more than 2 positions in the same footprint, that part is a drop-in alternative.
