Product details

54-Position Dual-Row Unshrouded Header

The 77313-801-54LF: The through-hole solder termination and 0.095" (2.41 mm) post length suit standard PCB thicknesses.

The 3 A per-contact rating is the current ceiling at the 0.100" pitch — above that, the temperature rise in the phosphor bronze contact and thermoplastic housing (UL 94 V-0) exceeds the material limits.

This is a male pin header with square 0.025" (0.64 mm) posts, 0.230" (5.84 mm) mating length. Termination is through-hole solder. All 54 positions are loaded; no breakaway option on this variant.
