Frequently Asked Questions
How many positions does the TSM-129-03-T-DH-A-P-TR provide, and what is the row pitch for PCB footprint planning?
The TSM-129-03-T-DH-A-P-TR provides 58 total positions in a dual-row (DH) layout, giving 29 pins per row with a 0.100" (2.54 mm) center-to-center pitch. Engineers planning the PCB footprint should account for a connector body length of approximately 29 x 2.54 mm = 73.66 mm per row, plus the standard SAMTEC keep-out margins at each end.
What does the -P polarization suffix on the TSM-129-03-T-DH-A-P-TR prevent during board assembly and field mating?
The -P polarization option adds a mechanical key or slot that ensures the mating connector can only be inserted in the correct orientation, preventing 180-degree mis-insertion on a 58-position dual-row header. Polarization is especially important for connectors carrying mixed signal and power pins where a reversed connection could damage circuits; it eliminates the need for individual pin-out verification during high-volume SMT assembly at production rates of 100 or more boards per hour.
Which automated assembly processes are compatible with the tape-and-reel format of the TSM-129-03-T-DH-A-P-TR?
The TSM-129-03-T-DH-A-P-TR ships in tape-and-reel (TR) format compatible with standard 8 mm or 12 mm component feeder tracks on SMT pick-and-place machines, enabling placement at throughputs of several thousand components per hour. The connector's surface-mount terminations are compatible with SAC305 or Sn63Pb37 reflow profiles with peak temperatures up to 260°C, integrating cleanly into existing SMT production flows.
How does the TSM-129-03-T-DH-A-P-TR compare to a single-row 58-position alternative in terms of PCB footprint and signal density?
A dual-row 58-position connector like the TSM-129-03-T-DH-A-P-TR occupies roughly half the board length of a single-row 58-position strip at the same 2.54 mm pitch, reducing the connector footprint from approximately 147 mm to 73.66 mm along the connector axis. This halved length is critical in space-constrained PCB designs where routing 58 signals in a single row would consume too much board edge or center area.
