Frequently Asked Questions
How many positions does the TSM-128-03-T-DH-P-TR provide, and what is its contact pitch?
The TSM-128-03-T-DH-P-TR provides 56 positions in a dual-row arrangement with a 0.100" (2.54 mm) pitch. This standard pitch ensures broad compatibility with mating SAMTEC TSW and TFM series headers and is widely supported by PCB layout tools and SMT assembly equipment.
What does the -TR suffix indicate for the TSM-128-03-T-DH-P-TR, and how does it benefit production?
The -TR suffix indicates tape-and-reel packaging, which enables automated pick-and-place SMT assembly at production rates suitable for high-volume manufacturing. Tape-and-reel parts reduce manual handling, minimize placement errors, and support reel sizes that can hold thousands of 56-position connectors per reel.
In what types of board-to-board stacking applications is the TSM-128-03-T-DH-P-TR commonly used?
The TSM-128-03-T-DH-P-TR is commonly used in 0.100" pitch board-to-board stacking configurations for industrial control cards, backplane-to-daughtercard interfaces, and test fixture sockets. Its 56-position dual-row layout allows up to 56 signals on two rows, consolidating power and I/O routing in compact multi-board systems.
Does the TSM-128-03-T-DH-P-TR meet RoHS requirements, and what is its lifecycle status?
SAMTEC TSM series connectors including the TSM-128-03-T-DH-P-TR are RoHS compliant and lead-free, meeting EU Directive 2011/65/EU. The part is an active product in the SAMTEC catalog, and its gold-plated contacts maintain low contact resistance across the rated mating cycles, supporting long production life cycles.
