The 6-1971895-2: The 5.00 mm pitch is a common power-pitch that also accommodates signal routing. The 2-position count makes this header suitable for a single sensor feed, a low-current power tap, or a simple on/off control line. The through-hole mounting provides a robust solder joint that withstands cable strain better than an SMT equivalent. The contact length after the solder tail is 0.138 inches (3.50 mm), which fits standard PCB thicknesses from 1.6 mm to 2.4 mm with adequate through-hole fill.
Thermal and Environmental Ratings
Glow wire compliance (IEC 60695-2-11) adds safety for household appliance applications. The voltage rating is 250VAC, suitable for single-phase AC distribution and many DC bus voltages up to 250V.
Peer Comparison: 1-2232960-3
The 2.50 mm pitch allows denser board layouts but carries a lower current ceiling per circuit. Both are through-hole, shrouded, UL94 V-0, and active.
