RoHS compliance is standard for this series. ## Board-to-Board Fit and Mating Half Push-pull fastening means no locking latch; in a vibration environment, a mating socket with a friction lock or a dab of thread-locker on the pin tails can help. The 0.230\" (5.84 mm) mating pin length engages fully with most standard receptacles.","metaTitle":"93992-121HLF Amphenol ICC (FCI) Bergstik II 21-Pin Header","metaDescription":"Active 21-position single-row header, 0.100\" (2.54 mm) pitch, 3 A, 30 µinch gold plating.
