2.54mm pitch, 8 positions — the board-fit check
The 5-520315-8: With 8 positions, this vertical through-hole connector accepts FFC or FPC cable 0.13mm to 0.38mm thick — the kinked pin termination holds the flex securely during assembly and rework. The 25 mating cycles reflect the tin finish — adequate for internal connections or test points where the flex is mated once and left alone, not for repeated field reconnects.
