Product details

16-Position, 4.20mm Pitch, Dual-Row Header with Board Lock

The 0039299166 is a 16-position, dual-row vertical header from the Mini-Fit Jr 5566 series, with a 4.20mm mating pitch and 4.20mm row spacing.

Tin-Plated Contacts and UL94 V-0 Housing

This header mates with Mini-Fit Jr 5556 series crimp receptacle housings.
