Crimp socket for 18-20 AWG wire
The 1241380-1 is the 18-20 AWG tin-plated socket member of the MCP 1.5K crimp contact line.
Comparing with 16 AWG siblings
Within the MCP 1.5K series the 1241380-1 handles 18-20 AWG, while the 1-1326032-0 socket accepts 16 AWG and carries a thicker 31.5µin (0.80µm) tin plating — the wire gauge and plating thickness are the selection axes between the two. The 929989-8 socket also covers 17-20 AWG with tin finish and shares the same crimp termination style, offering a slightly wider wire range on the low end.
