The 215464-6 is a 6-position, 2-row shrouded header from TE's Micro-MaTch series, built for board-to-board or cable-to-board signal interconnect. The tin contact finish (3.00 µm thick on the mating face) handles moderate mating cycles; for a field-service connector cycled quarterly, that tin layer resists fretting corrosion well within the product's service life.
Through-hole mounting with a choice of press-fit or solder termination. Press-fit suits high-reliability backplane assemblies where you want to avoid solder joints; solder gives a traditional through-hole connection for standard wave or hand-solder processes. The 0.122" (3.10 mm) post length works with 1.6 mm PCBs, leaving enough tail for a good fillet.
No official second-source cross-reference exists; the Micro-MaTch series is TE-specific, so plan to source the mating receptacle from the same family.
How It Compares Within the Micro-MaTch Series
Within the Micro-MaTch family, the 215464-6 sits at the low end of position counts — 6 circuits in 2 rows. If you need more I/O, the series offers variants up to 20 positions in the same 2-row, 0.100" pitch footprint. The tin contact finish and 1.5 A rating are consistent across the line; the difference is purely the circuit count and the board real estate it occupies.
