The 10129378-936002BLF: The header is cuttable — a single 36-position strip can be snapped into shorter lengths, letting one part number cover multiple BOM positions with different circuit counts. The through-hole solder tails (0.090" post length) anchor into the board with mechanical strength that surface-mount parts lack under repeated cable strain.
Operating Range and Flammability Rating
Rated at 110 VDC, the voltage ceiling is typical for signal-level interconnects inside low-voltage equipment; it is not a power-distribution part.
