What this 72-position right-angle header does
The 353830-5: This is a 72-position, 3-row header from TE Connectivity's AMP Connectors line, terminated through-hole and oriented right-angle to the board. Mounting brackets add a mechanical anchor point beyond the solder joints, reducing shear stress on the pins from cable strain. The tin-on-tin contact finish suits moderate mating-cycle applications in cost-sensitive designs.
The pitch is not explicitly listed in the evidence, but the 3-row, 72-position layout with 0.888" (22.56mm) insulation height and 0.280" (7.11mm) mating pin length defines a specific board footprint. Confirm the mating receptacle's pitch and keying before committing the BOM.
