At a 0.100" (2.54mm) mating pitch — the same as legacy DIP ICs — it drops into any PCB laid out for standard 0.100" header footprints. 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.
