What are the key features of TSM-128-04-SS-DH-A-P-TR?
- 56 positions in a dual-row 0.100" (2.54 mm) pitch layout for high-density signal routing
- Solder shoulder (SS) lead style improves mechanical retention and solder joint robustness
- Surface mount termination compatible with standard SMT reflow assembly equipment
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place production
- Dual-row arrangement reduces board edge length by roughly 50% versus a single-row 56-pin strip
What is TSM-128-04-SS-DH-A-P-TR used for?
TSM-128-04-SS-DH-A-P-TR is used in board-to-board, module-to-carrier, and backplane signal interconnect applications across industrial automation, embedded computing, and communications platforms. The solder shoulder lead style is particularly beneficial in designs subject to mechanical vibration or handling stress, where additional joint robustness on all 56 contacts helps maintain signal integrity over the product service life.

Frequently Asked Questions
What advantage does the solder shoulder (SS) lead style of TSM-128-04-SS-DH-A-P-TR provide over a standard surface mount lead?
The solder shoulder (SS) lead style on TSM-128-04-SS-DH-A-P-TR creates a larger contact area between the lead and the PCB pad, increasing solder joint mechanical strength. This is beneficial in designs subject to vibration or repeated handling, where standard SMT leads on 56-position connectors may experience fatigue at the solder joint after prolonged stress cycling.
How many signal contacts does TSM-128-04-SS-DH-A-P-TR provide, and what connector pitch does it use?
TSM-128-04-SS-DH-A-P-TR provides 56 signal contacts arranged in 2 rows at 0.100" (2.54 mm) pitch. With 28 contacts per row, the connector body spans approximately 2.8 inches, making it a compact yet high-density solution for embedded computing and industrial PCB designs.
Is TSM-128-04-SS-DH-A-P-TR suitable for use in industrial environments with thermal cycling requirements?
Yes. SAMTEC TSM series connectors are rated for operating temperatures from -55°C to 125°C, and the solder shoulder lead style of TSM-128-04-SS-DH-A-P-TR provides added mechanical stability during thermal expansion and contraction cycles. This makes the connector suitable for industrial equipment exposed to wide temperature swings in factory, outdoor, or transportation environments.
How does TSM-128-04-SS-DH-A-P-TR compare to TSM-128-04-L-DH-A-P-TR as a drop-in alternative for the same board layout?
TSM-128-04-SS-DH-A-P-TR and TSM-128-04-L-DH-A-P-TR share the same 56-position dual-row 0.100" pitch body but differ in lead style: SS provides a solder shoulder for enhanced joint strength, while L provides an angled (right-angle) lead for horizontal mating orientation. They are not interchangeable without a PCB footprint revision, as the solder pad patterns for SS and L leads differ.
