The 93992-121HLF: The 21 circuits are fully loaded, so every pin is present for signal or low-power distribution.
RoHS compliance is standard for this series.
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.
This is the standard 0.1-inch grid compatible with breadboards and prototyping boards.
Bergstik II headers typically use a higher-performance contact material (phosphor bronze vs. brass in Bergstik I) and offer a wider range of plating options including 30 µinch gold. For this specific 93992-121HLF, the phosphor bronze contacts with 30 µinch gold plating give better spring properties and corrosion resistance than a standard Bergstik I equivalent.
