Right-angle 3.81 mm pitch — board-edge routing fit
The 2342077-4: This is a 4-position, single-row, right-angle shrouded header on a 0.150" (3.81 mm) pitch. The 0.285" (7.25 mm) insulation height gives the shroud enough depth to fully cover the mating receptacle pins and provide polarisation keying. The 11 A rating is the UL-rated maximum; in a dense harness bundle or elevated ambient, derate per the TE application note for this series.
High-temp nylon housing — 105°C continuous
The tin contact finish is adequate for the temperature range; gold would extend cycle life but is not required for thermal endurance.
