The TE Connectivity 2106212-1 is a 2-position hermaphroditic blade-and-receptacle connector on a 0.157" (4.00mm) pitch, designed for board-to-board interconnects. The hermaphroditic body means each half is identical — no separate male and female parts to stock or mis-match, which simplifies field assembly and inventory.
The closest functional peer is the 1-2213614-1, which shares the same 0.157" (4.00mm) pitch, 2-position count, 6A rating, and hermaphroditic blade-and-receptacle design — but swaps the tin contacts for gold plating. The gold finish on the 1-2213614-1 supports higher mating cycle life and better corrosion resistance, making it the better choice for frequent reconnection or harsh environments. The 2106212-1 with tin contacts is adequate for permanent or low-cycle installations where cost is the driver.
