Frequently Asked Questions
How many total contact positions does TSM-128-02-F-DH-A-P-TR provide and how are they arranged physically?
TSM-128-02-F-DH-A-P-TR provides 56 positions arranged in a dual-row (DH) configuration at 2.54 mm (0.100 inch) pitch. This dual-row layout packs 28 contacts per row, enabling dense signal and power routing within a compact SMT footprint suitable for board-to-board and expansion header applications.
What does the A-type friction lock housing on TSM-128-02-F-DH-A-P-TR contribute to mechanical retention in mated assemblies?
The A-type housing designation indicates a friction-lock design that provides positive engagement force to retain the mating connector without requiring latches or screws. This mechanical retention is particularly useful in 56-position connectors where individual contact forces accumulate, reducing the risk of accidental unmating in vibration-prone industrial or embedded computing environments.
When sourcing TSM-128-02-F-DH-A-P-TR for a new production design, what packaging and placement considerations apply?
The TR suffix specifies tape-and-reel packaging, which is compatible with automated SMT pick-and-place machines. At 56 positions per connector, correct orientation during placement is critical; engineers should verify the reel orientation in feeder setup and confirm pad spacing matches the 2.54 mm pitch dual-row footprint before starting production runs.
In which high pin-count design scenarios is TSM-128-02-F-DH-A-P-TR preferable to single-row header alternatives?
When a design requires 56 or more signal and power connections between boards, a dual-row 2.54 mm pitch connector like TSM-128-02-F-DH-A-P-TR uses roughly half the PCB edge length compared to a single-row alternative with the same 56 pins. This compact footprint benefits FPGA daughter boards, backplane mezzanine cards, and modular control systems where board real estate is limited.
