Frequently Asked Questions
How many positions does the TSM-127-02-TL-DH-A-K-TR have and how are they arranged?
The TSM-127-02-TL-DH-A-K-TR features 54 positions arranged in a dual-row (2 × 27) configuration with 2.54 mm (0.100 inch) pitch, providing a compact, high-density footprint for surface mount PCB applications.
What current and voltage ratings apply to the TSM-127-02-TL-DH-A-K-TR for signal and power connections?
Each pin of the TSM-127-02-TL-DH-A-K-TR is rated at 3 A current capacity and 250 V AC/DC, making it suitable for digital signal lines and low-current power rails in embedded and industrial boards.
Why is the tape-and-reel (TR) packaging format important for high-volume PCB assembly?
The TR suffix indicates tape-and-reel packaging, allowing automated pick-and-place machines to mount the TSM-127-02-TL-DH-A-K-TR at high speed. This reduces manual handling, improves placement accuracy to within ±0.05 mm, and lowers per-unit assembly cost in large production runs.
What alternatives should engineers consider when the TSM-127-02-TL-DH-A-K-TR is unavailable?
Engineers can evaluate the SAMTEC TSM-127-01 series with different plating options, or compatible 54-position dual-row 2.54 mm SMT headers from TE Connectivity (GRPB-27-XX-XXX-XX) and Wurth Elektronik. Confirm identical 2.54 mm pitch, 27 × 2 row count, and SMT footprint before substituting.
