1.25 mm Pitch Right-Angle SMT Header for Signal-Density Routing
The 1734261-8 is an 8-position, single-row header from TE's High Performance Interconnect (HPI) series, using a 0.049" (1.25 mm) pitch that packs signal contacts tightly for board-edge cable exits in space-constrained designs.
Compared to the 1-2232960-3 (3-position, 2.50 mm pitch, through-hole, locking ramp), the 1734261-8 offers a finer pitch for higher-density routing but trades the locking ramp for a shrouded 4-wall design and lower current capacity. Against the 1376366-8 (8-position, 2.20 mm pitch, through-hole, 5 A), the 1734261-8 saves board space with a 1.25 mm pitch and SMT assembly, but at a 1 A current ceiling — choose based on power vs density priority.
