80-position breakaway header on 0.100-inch pitch
The 9-146258-0: The through-hole solder tails and square male pins make it a direct fit for wire-to-board or board-to-board connections where you need a high circuit count on a dense grid. The wide temperature envelope suits equipment inside enclosures where ambient heat builds, such as industrial control panels or outdoor telecom cabinets.
Tin-plated contacts for moderate-duty signal paths
The base product number is 146258.
Peer comparison: tin vs gold, 80 vs 8 positions
The closest functional peer is 9-146257-0: same 80-position, 0.100" pitch, through-hole layout, and active lifecycle — but with 30 µinch gold on the mating contact instead of tin. Gold buys higher mating cycle endurance (500+ cycles typical) and better corrosion resistance in aggressive atmospheres. The 8-position sibling 5-146254-4 shares the same tin plating and pitch but at a fraction of the circuit count — a direct comparison only on position count, not on footprint.
