Product details

Board Fit and Routing – 28 Positions at 0.100" Pitch

The 77313-822-28LF: The 28-position count lands between common 26- and 34-position sizes, useful for 16-bit data buses or mixed I/O where a 26-position is too tight and a 34-position leaves unused pins.

The mating surface carries gold or GXT™ plating at 15.0 µinch (0.38 µm) minimum thickness over phosphor bronze base metal – a standard for 500+ mating cycles in controlled environments. The thicker gold layer resists fretting corrosion better than flash gold, making this header a good fit for equipment that sees periodic reconnection during maintenance or rework.

Frequently asked questions

Can 77313-822-28LF be replaced by a similar header from another brand?

A direct pin-compatible replacement would need the same 28 positions, dual-row 0.100" pitch, unshrouded breakaway form factor, and through-hole termination. Several manufacturers offer equivalent headers in the same footprint – confirm the mating contact finish (gold vs. tin) and overall length to match your application.
