The latch lock/eject hooks provide a positive audible click on mating — vibration won't back the header out of the receptacle. ## Mounting Flange and Keying Slot for Field Fit A keying slot prevents cross-mating with non-keyed receptacles — a simple but effective mis-mate guard. The mounting flange provides a mechanical anchor to the board, taking shear force off the solder joints when the cable is tugged. On site, if a header has been pulled loose, the flange lets you re-seat and re-solder without replacing the whole assembly, provided the pins are intact. The through-hole solder termination is field-repairable with a basic soldering iron and desoldering braid. ## Cross-Reference and Compatibility The base product number 66429 covers the series; the -073LF suffix specifies the 26-position, right-angle, gold-plated variant. If you need a different position count or plating, check other suffixes under the 66429 base — but confirm the mating half and board footprint before switching.","metaTitle":"66429-073LF Amphenol ICC (FCI) Quickie™ Header 26 Pos R/A","metaDescription":"Active 26-position right-angle header, 0.100\" pitch, 30µin gold mating, shrouded 4-wall, latch lock.
