Pitch and position count define the footprint
The 5-520315-2: The vertical through-hole orientation places the FFC entry perpendicular to the board, saving lateral space at the cost of z-height — the height above board is 0.273" (6.93mm).
Tin-plated contacts with 25 mating cycles — this is a cost-optimized interface for infrequent disconnects, not repeated field-service reconnects.
FFC thickness and termination
Accepts FFC thickness from 0.13mm to 0.38mm — covers standard 0.3mm ribbon as well as thinner flex circuits. Kinked pin termination aids through-hole insertion and retention during wave soldering.
ROHS3 compliant. Housing is UL94 V-0 rated polyester thermoplastic, glass filled.
