Frequently Asked Questions
How many positions and what pitch does the TSM-128-03-S-DH-P-TR provide for PCB layouts?
The TSM-128-03-S-DH-P-TR offers 56 positions arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch, making it suitable for high-density signal interconnects on standard SMT PCB assemblies.
Is the TSM-128-03-S-DH-P-TR suitable for automated SMT assembly lines?
Yes. The TR suffix denotes tape-and-reel packaging, so the connector is compatible with automated pick-and-place equipment. Its SMT termination style supports reflow soldering at standard lead-free profiles up to 260°C, streamlining high-volume production.
What contact plating does this SAMTEC terminal strip use, and how does it affect signal integrity?
The TSM-128-03-S-DH-P-TR uses gold-plated contacts, which provide low and stable contact resistance across 56 pins, reducing signal loss and maintaining reliable connections even after repeated mating cycles in test and measurement applications.
Which alternative SAMTEC part numbers should engineers consider if this 56-position strip is unavailable?
Engineers can evaluate adjacent SAMTEC TSM series variants with different position counts—such as 40-position or 64-position options—or equivalent .100" pitch SMT headers from the SAMTEC SSM or TSW series, all sharing the same 2.54 mm grid.
