Product details

SlimStack 53309 Board-to-Board Header

With a 0.031" (0.80mm) pitch and two rows, it packs 40 circuits into a compact footprint for parallel-stacked PCBs. This is a signal-density part — the 0.80mm pitch and tin contact finish suit moderate-cycle internal connections where gold is not required.

The contacts carry a tin finish at 120.0µin (3.05µm) thickness. It is not gold, so it is not the right choice for frequent field reconnection or corrosive atmospheres. The thickness at 120.0µin is on the heavier side for tin, which helps with wear life in the intended duty cycle.

Frequently asked questions

What is the mating connector for 0533094070?

The 0533094070 is the header (male) half of a SlimStack 53309 board-to-board pair. It mates with a matching SlimStack receptacle from the same series — the receptacle part number depends on the desired stack height and position count. The 0.80mm pitch and 4.70mm header height determine the mated stack height with the corresponding receptacle.
