What are the key features of TSM-128-03-FM-DH-P-TR?
- 56 positions in a dual-row 0.100" (2.54 mm) pitch configuration for dense I/O routing
- Female machined contacts (FM suffix) for precision mating with corresponding header pins
- Surface-mount with dual-row headers and tape-and-reel (TR) for pick-and-place automation
- DH variant combines SMD and through-hole tails for enhanced mechanical board retention
- SAMTEC precision machined contacts delivering consistent electrical performance across mating cycles
What is TSM-128-03-FM-DH-P-TR used for?
TSM-128-03-FM-DH-P-TR is used in dense backplane interconnects, FPGA daughter cards, and high-channel-count test and measurement interfaces where 56 signal pins at 2.54 mm pitch are required in surface-mount form. The tape-and-reel packaging supports volume production lines for industrial computing, communications infrastructure, and embedded control applications.

Frequently Asked Questions
How many positions does TSM-128-03-FM-DH-P-TR provide and what is the pin pitch?
TSM-128-03-FM-DH-P-TR provides 56 positions on a dual-row 0.100" (2.54 mm) pitch layout. This gives designers 56 signal or power pins in a compact SMT footprint compatible with standard 2.54 mm grid PCB designs used in industrial and communications hardware.
What does the FM suffix indicate, and why choose machined contacts for this connector?
The FM suffix denotes female machined contacts, which offer tighter dimensional tolerances and longer mating cycle life compared to stamped contacts. For a 56-pin, 0.100" pitch connector used in FPGA or backplane applications, machined contacts ensure repeatable low-contact-resistance mating across hundreds of insertion cycles.
Does TSM-128-03-FM-DH-P-TR support automated SMT assembly, and what packaging is it offered in?
Yes. The TR suffix confirms tape-and-reel packaging, fully compatible with standard SMT pick-and-place equipment. The 56-position dual-row body also includes through-hole tails (DH suffix) that anchor the connector to the PCB, improving solder-joint reliability in vibration-prone industrial or computing environments.
When would a procurement team select TSM-128-03-FM-DH-P-TR over a lower pin-count alternative?
Engineers specify TSM-128-03-FM-DH-P-TR when 56 pins are required to carry parallel data buses, GPIO expanders, or multi-channel sensor signals on a single 0.100" pitch connector. Choosing 56 positions over two separate 28-pin connectors reduces board placement steps and aligns all 56 signals on a single 2.54 mm pitch row pair.
