8-Circuit SMT Header – No Boss, Wire-to-Board
The 55450-0869 is an 8-circuit SMT pin header from Molex, described as a Mini-MI2 SMT wire-to-board assembly without a keying boss. This means the header mates with a corresponding receptacle that does not require a boss alignment feature — useful in space-constrained or low-profile harness layouts where the boss would interfere with adjacent components.
