What This 110-Position Backplane Receptacle Does
The TE Connectivity 100147-1 is a 110-position receptacle from the Z-PACK series, built for dense backplane interconnects where you need to pack a lot of signal lines into a board-edge footprint. The 0.079" (2.00mm) pitch keeps routing manageable — tight enough for 110 circuits across 5 rows, but not so fine that you need micro-via layers to escape the footprint. Each contact is rated 1.5 A, which is typical for a high-density signal connector at this pitch; the 500Vrms voltage rating is higher than you'd expect for 2.00mm pitch, so the housing creepage distances are generous for the class. The press-fit termination is the key differentiator here — no solder means no wave solder defects, no flux residues, and the connector can be pressed into plated through-holes on a backplane in one operation. The connector style is listed as A 22, which is a Z-PACK keying variant — the mating pin header must match this keying code to avoid cross-mating with other Z-PACK connectors on the same backplane.
This is a receptacle (female sockets), so it mates with a Z-PACK pin header (male pins) of the same 110-position count, 5-row layout, and A 22 keying. The press-fit tails go into 0.040" (1.02mm) plated through-holes on the backplane — the hole size and finished plating thickness matter for the press-in force, so use TE's recommended PCB layout from the product drawing.
