Product details

20-Pin Unshrouded Header on 0.100-Inch Grid

The 77311-101-20LF: The UL94 V-0 thermoplastic housing keeps it compliant for equipment inside enclosures where flame rating matters.

Footprint and Routing Fit

The 0.100" pitch sets a straightforward PCB footprint: a row of 20 plated through holes on 2.54 mm centers. The mating pin length of 0.230" (5.84 mm) provides enough reach for standard receptacles, while the post length of 0.095" (2.41 mm) suits boards up to about 1.6 mm thick before the solder tail protrudes beyond the bottom side.

Current and Contact Life

The tin-plated solder tails (78.7 µinch) are standard for wave solder wetting.

Bulk packaging is the standard package option.
