The 5-794630-2: This is a 22-position, 2-row vertical header from the Micro MATE-N-LOK series. All 22 positions are loaded, which means no blank cavities to account for in the harness layout.
What mates with it — the three-part kit
The 4-wall shroud guides the housing straight on, so pin stubbing is unlikely even in blind-mate scenarios behind a panel.
Press-fit or solder — termination flexibility
The through-hole termination supports both press-fit and solder assembly. Press-fit is the cleaner option for backplane builds where rework is a concern — the compliant pin cold-welds to the plated through-hole without thermal stress. Solder gives a more conventional joint for single-board assemblies where wave or selective soldering is already in the process flow.
Voltage, temperature, and flammability — what the ratings mean
Rated 250 V, which covers most low-voltage DC distribution and signal-level AC circuits inside equipment. UL94 V-0 means the material self-extinguishes within 10 seconds, a standard requirement for equipment inside a flame-rated enclosure.
