Product details

Board-to-harness header for 3.00mm pitch Micro MATE-N-LOK

The 3-794631-4 is a 4-position, 2-row vertical header from TE's Micro MATE-N-LOK series, on a 3.00mm pitch. It mates with the corresponding Micro MATE-N-LOK receptacle housing to form a board-to-cable/wire connection.

Termination and mating: press-fit or solder, gold on pins

Termination is through-hole with both press-fit and solder options — the press-fit route eliminates soldering for rework-friendly assembly. The header mates with Micro MATE-N-LOK receptacle housings using the locking ramp for positive retention.

Peer comparison: 1-1871673-2 vs 3-794631-4

The closest functional alternative is TE's 1-1871673-2, also a 4-position, 2-row shrouded header, but on a 2.50mm pitch with tin mating finish and a right-angle orientation. The 3-794631-4 uses 3.00mm pitch, gold mating, and vertical orientation — a different footprint and mating half.
