The 350787-3 is a 2-position, single-row, through-hole header from the Universal MATE-N-LOK series by TE Connectivity AMP Connectors.
This header mates with a Universal MATE-N-LOK receptacle housing (e.g., 1-480698-0 for 2 positions) loaded with the appropriate crimp socket contacts. The through-hole solder termination requires a 0.215" (5.46 mm) post length for the PCB hole.
The closest sibling in the Universal MATE-N-LOK series is the 350787-4 (4 positions), which shares the same pitch, plating, and housing material but adds two more circuits.
