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. No official successor or cross-reference from TE. ## 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.","metaTitle":"1744439-3 TE Connectivity Economy Power 2.5 Header, 3 Pos","metaDescription":"1744439-3 TE Connectivity AMP Connectors header, 3 circuits, 2.50mm pitch, 4.2A, tin contacts, friction lock, UL94 V-0.
