Product details

64-Pin Dual-Row Breakaway on 2.54mm Pitch

The 77313-124-64LF: Rated 3A per contact, the current ceiling is limited by the 30°C temperature rise through the phosphor bronze contacts.

Through-hole termination with a 0.114" (2.90mm) post length and 0.480" (12.19mm) overall contact length. The 0.266" (6.75mm) mating pin length gives enough standoff for the receptacle to fully seat without bottoming out on the housing. Insulation height is 0.100" (2.54mm) above the board, keeping the z-height low for dense card cages.

Rated for -65°C to 130°C continuous operation — the thermoplastic housing (UL94 V-0) keeps the material properties stable across industrial and outdoor telecom temperature swings.

Frequently asked questions

What is the pinout of 77313-124-64LF?

The pinout is a standard dual-row layout with all 64 positions loaded. Row spacing is 0.100" (2.54mm), matching the pitch. The breakaway design means individual sections can be snapped apart — but this part ships as a full 64-position strip.

Is 77313-124-64LF shrouded or unshrouded?

Unshrouded. There is no plastic shroud around the pins — the male pins are exposed. This means the mating receptacle must provide its own alignment or the board layout must guide the pair together. No keying feature.
