2.50 mm Pitch, 3 Positions — Wire-to-Board Power Tap
Glow Wire and Flame Rating — Appliance-Ready
ROHS3 compliant — covers the full substance restriction list for EU and many global markets.
Through-Hole Kinked Pin — Solder Retention
Termination is kinked pin, solder, through-hole. The kink provides mechanical retention during wave solder — the pin won't fall out before the solder solidifies. Through-hole mounting gives a stronger anchor than SMT for a connector that sees repeated cable strain. Contact length after the board is 0.134" (3.40 mm) — typical for standard PCB thicknesses. The post finish is 80 µin tin, matching the mating finish.

Peer Comparison — 1-2232960-3 vs 1-1871673-2
The closest functional second-source is 1-2232960-3: same 2.50 mm pitch, same 3 positions, same single-row shrouded header, but rated 2 A at 50 VAC with a locking ramp instead of friction lock. The 1744439-3 carries double the current (4.2 A) and a higher voltage rating (250 VAC), making it the heavier-duty choice for power taps. The 1-1871673-2 is a dual-row, 4-position, right-angle header with detent lock and board lock — different orientation, row count, and mounting. Not a direct cross for a single-row vertical application.
