8-position, 2.54mm pitch Micro-MaTch receptacle
Tin plating and friction lock for moderate duty
For a connector that sees one or two matings during assembly and then stays mated for the product life, tin is a reliable, low-cost finish. The friction lock adds a tactile confirmation that the header is fully seated and resists un-mating from vibration.
The closest peer in the same series is 1-2823056-2, a 12-position receptacle with the same 2.54mm pitch and tin finish, but in a black PA46 housing and surface-mount termination. The 338070-8 is through-hole and red, so the choice comes down to position count and assembly process — 8 positions vs 12, and solder-through-hole vs reflow.
