What are the key features of TSM-127-02-TL-DH-P-TR?
- 54-position dual-row right-angle SMT terminal strip at 2.54 mm (0.100") pitch
- Extended tail-length (-TL) variant for improved solder joint strength and board retention
- Right-angle (-02) termination enabling horizontal board-edge mating in low-profile assemblies
- Tape-and-reel (-TR) packaging for high-speed automated pick-and-place assembly
- Dual-row (DH) layout providing 27 contacts per row for high signal density
What is TSM-127-02-TL-DH-P-TR used for?
TSM-127-02-TL-DH-P-TR is used in edge-mounted board-to-board interconnects for embedded computing, industrial controllers, and data acquisition systems requiring a 54-pin right-angle SMT interface at standard 0.100" pitch. The extended tail length provides enhanced solder joint pull strength, making it suitable for applications subject to mechanical vibration or cable tension.

Frequently Asked Questions
What does the -TL suffix indicate on the TSM-127-02-TL-DH-P-TR, and why does it matter for connector reliability?
The -TL suffix designates an extended tail-length variant for the SMT termination leads. Longer solder tails increase the contact area with the PCB pad, improving solder joint pull strength and mechanical retention. This is particularly valuable in designs where the connector may experience vibration loads or where cables attached to the mating connector exert pull forces on the solder joints.
How does the 54-position count of TSM-127-02-TL-DH-P-TR compare to nearby TSM series variants for bus width selection?
At 54 positions in a dual-row 2.54 mm (0.100") pitch layout, the TSM-127 provides 27 contacts per row, positioning it between the 50-pin (TSM-125) and 56-pin (TSM-128) variants. Designers can select this specific count to exactly match the bus width required by their signal interface, avoiding unnecessary unused pins and reducing connector cost.
Can TSM-127-02-TL-DH-P-TR be processed through a standard SMT reflow oven, and what temperature profile does it support?
Yes. The surface mount termination style and tape-and-reel packaging make TSM-127-02-TL-DH-P-TR fully compatible with standard SMT reflow processing. SAMTEC TSM series connectors are designed to withstand peak reflow temperatures of 260°C for up to 30 seconds, consistent with IPC/JEDEC J-STD-020 requirements for SMT components.
