What This ULTRA-FIT Header Is
The 172298-1210: This is a Molex ULTRA-FIT vertical header, dual row, with 10 circuits in a black housing. The 'VT' in the description confirms the pins are perpendicular to the board — a straight-through orientation that keeps the mated connector assembly low-profile above the PCB. The header is supplied in Tray packaging, which is typical for machine-placed components in volume assembly.
Note that this part is RoHS non-compliant, so it is not suitable for BOMs requiring RoHS conformance. Confirm your application's regulatory requirements before committing the line item.
