High-Density Backplane Header for Press-Fit Assembly
The TE Connectivity 1934299-1 is a 72-position header from the Z-PACK TinMan series, built as a high-speed backplane connector. It uses a 9-row by 8-column grid on a 0.075" (1.90mm) pitch — that pitch is the tightest in the TinMan family, which means the backplane PCB needs careful trace routing to escape the connector footprint without adding extra layers. The press-fit termination eliminates solder defects common in high-density through-hole arrays and allows individual pin replacement if a contact gets damaged during board assembly.
Signal Duty Only — Current Rating Tells the Story
Rated 0.5A per contact, this header is strictly for signal paths — don't plan on pushing power through it. The 250V voltage rating is typical for backplane signal levels. The 0.5A limit comes from the fine-pitch contact geometry and the dense 9-row arrangement; the current per pin is derated further if the backplane runs warm. Operating temperature from -65°C to 90°C covers outdoor telecom cabinets and industrial enclosures, but the upper end means the 0.5A rating holds only up to that ambient — above 90°C the connector isn't rated to carry current at all.
Press-Fit Termination Saves the Solder Wave
The press-fit through-hole termination is the right choice for a backplane that sees multiple rework cycles or uses a mix of through-hole and surface-mount components. The compliant press-fit pin cold-welds to the plated through-hole wall — no solder, no flux residue, no void inspection. If a pin gets bent or a trace needs re-routing, you can push the pin out with a simple tool and replace it without desoldering the whole connector.
Mating Half and Footprint
This header mates with the Z-PACK TinMan receptacle (the female half of the same series). The 72-position count with all positions loaded means the footprint is a 9 x 8 grid — verify your backplane PCB layout matches that column and row arrangement. The 0.075" (1.90mm) pitch is tighter than the standard 0.100" backplane pitch, so confirm your trace escape strategy before committing the board.
