Within the same Rib-Cage™ III series, the 87409-145LF (90 positions) sits between the 87409-140LF (80 positions) and the 87409-150LF (100 positions). For a BOM requiring 90 signal lines, the 87409-145LF is the exact fit; the 80-position version leaves lines unconnected, while the 100-position version adds unused pins. ## Surface-Mount Termination and Board Layout The header terminates via surface-mount solder tails, with tin-plated posts (100 µinch thickness) for reliable solder joint formation. The 1.27 mm pitch and 0.050\" row spacing demand a precise PCB footprint — the 90 pins occupy a 45-pin-per-row layout, and the 6.42 mm stack height sets the z-height budget for the mezzanine gap.","metaTitle":"87409-145LF Amphenol ICC (FCI) Rib-Cage™ III Header, 90 Pos","metaDescription":"87409-145LF Amphenol ICC (FCI) Rib-Cage™ III board-to-board header, 90 positions, 1.27mm pitch, SMT, 30µin gold mating, -55°C to 130°C.
