Product details

28-Position BergStik II Unshrouded Header

All 28 positions are loaded, so the pin count on the BOM line is the pin count on the board. That thick tin finish handles repeated mating cycles in moderate environments — think test equipment, industrial control panels, or internal board stacking where gold is overkill and the budget matters. The insulation height is a low 0.100" (2.54 mm), which keeps the profile tight above the PCB.

The 0.100" (2.54 mm) pitch is the defining dimension for board layout — it matches the vast majority of BergStik and legacy.025" square-post receptacles. The through-hole termination uses a 0.120" (3.05 mm) post length, which suits standard 0.062" PCBs.

Frequently asked questions

What is the pin pitch of 79425-428HLF?

The pitch is 0.100" (2.54 mm) on both rows, matching the standard BergStik grid.

What is the difference between 79425-428HLF and other BergStik headers?

The primary difference from other BergStik headers is the combination of 28 positions, dual rows, unshrouded design, and tin plating. A shrouded BergStik header (e.g., the 77311 series) adds a plastic wall for polarization and pin protection but uses the same 0.100" pitch and 5 A rating.
