What are the key features of TSM-127-02-TM-DH-P-TR?
- 54 positions in dual-row 0.100" pitch for high signal density in compact PCB designs
- Through-mount (TM) termination option for enhanced mechanical retention on PCB
- Surface mount design compatible with standard automated assembly equipment
- Tape-and-reel (TR) packaging supports continuous production with minimal changeover
- Dual-row contact arrangement maximizes channel count per millimeter of board edge
What is TSM-127-02-TM-DH-P-TR used for?
The TSM-127-02-TM-DH-P-TR is used in applications requiring a large number of signal or power connections in a compact area, such as embedded computing modules, industrial I/O expansion boards, and laboratory instrumentation. The through-mount termination provides additional mechanical strength compared to standard surface mount pads, beneficial in applications subject to vibration or repeated insertion cycles. Tape-and-reel packaging ensures compatibility with high-volume automated PCB assembly lines.

Frequently Asked Questions
What mechanical advantage does through-mount termination provide in TSM-127-02-TM-DH-P-TR compared to standard SMT pads?
Through-mount termination adds mechanical retention by anchoring the 54-position connector to the PCB through soldered through-holes in addition to surface pads, increasing pull-out force to typically over 50 N. This is critical for connectors in vibration-prone environments such as industrial control cabinets or automotive test rigs.
How does TSM-127-02-TM-DH-P-TR handle current distribution across its 54 contacts?
Each contact in the SAMTEC TSM series is rated for approximately 1.5 A, so the 54-position TSM-127-02-TM-DH-P-TR supports a total of up to 81 A when all contacts carry current. In practice, engineers distribute power and ground pins across multiple contacts to stay within the 1.5 A per pin thermal limit.
When sourcing TSM-127-02-TM-DH-P-TR in bulk, what reel quantities and lead times should procurement expect?
SAMTEC tape-and-reel SMT connectors typically ship in reels of 500 to 1000 pieces. Standard lead times from authorized distributors such as Digi-Key or Mouser are 6 to 10 weeks for large orders. Safety stock of at least 250 pieces per production quarter is recommended for programs with monthly build rates above 500 boards.
Which SAMTEC TSM variants are pin-compatible with TSM-127-02-TM-DH-P-TR for design flexibility?
SAMTEC TSM variants sharing the same 0.100 inch pitch and dual-row arrangement—such as TSM-127-02-F-DH-P-TR (flush mount) and TSM-127-02-L-DH-P-TR (elevated mount)—use compatible PCB footprints with 54 positions. Switching between mount height variants requires only a silkscreen and component selection change without redesigning PCB copper layers.
