All 34 positions are loaded, so there is no depopulated row to reconcile against the BOM. The 0.100\" (2.54mm) insulation height and 0.190\" (4.83mm) mating pin length give a standard stack height when paired with the matching receptacle. Within the BERGSTIK® II family, the key selection axis is position count. The 34-position 79425-434HLF sits between the 30-position and 36-position variants at the same 0.100\" pitch — match the circuit count on the board layout exactly. The unshrouded, push-pull fastening is consistent across the series; no keying, no latch. If the application needs polarization or a locking ramp, look at the shrouded BERGSTIK® II headers instead. Through-hole solder termination with a 0.120\" (3.05mm) post length — fits standard 0.062\" PCBs with room for the solder fillet. The 0.100\" (2.54mm) row spacing mirrors the footprint of a standard DIP socket, so layout is straightforward with any EDA library that includes 0.100\" header patterns.","metaTitle":"Amphenol 79425-434HLF BERGSTIK II Header, 34 Pos","metaDescription":"79425-434HLF BERGSTIK® II unshrouded header, 34 positions, 0.100\" pitch, 5A, tin-plated.
