The through-hole termination with a 0.120" (3.05mm) post length and 0.600" (15.24mm) overall contact length suits standard PCB thicknesses in the 0.062" to 0.093" range.
Fit and Mating
As an unshrouded male pin header, the 86837-446HLF mates with any standard 0.100" pitch, 46-position dual-row receptacle housing that accepts square 0.025" posts. The push-pull fastening type means retention depends entirely on the contact interference fit — no locking latch. The 0.380" (9.65mm) mating contact length provides good wipe before the pins bottom out, which helps with reliability in stacked board assemblies where board thickness varies.
The phosphor bronze contact material with full tin plating gives a solid balance of spring properties and solderability. For a board-to-board interconnect that will be mated once or twice over its service life, the tin finish is appropriate — it avoids the cost premium of gold while still meeting the 5A per contact current rating.
