Unshrouded Design and Mating Flexibility
The 4-102974-0-08: Unshrouded headers allow direct visual alignment during mating and accept a wide range of receptacle housings, though the pins are more exposed to mechanical damage compared to a shroud.

The 4-102974-0-08: Unshrouded headers allow direct visual alignment during mating and accept a wide range of receptacle housings, though the pins are more exposed to mechanical damage compared to a shroud.
The mating contact surface is gold (15.0µin thickness), with tin-lead plating on the solder posts. The gold finish supports repeated mating cycles with stable contact resistance.
It belongs to the AMPMODU Mod II series, a widely used 0.100-inch pitch breakaway header family from TE Connectivity.
