What are the key features of TSM-127-02-SM-DH-P-TR?
- 54 positions in a dual-row 0.100" (2.54 mm) pitch SMT package for high pin-count I/O headers
- Through-hole tails (DH) provide additional solder-joint mechanical retention in vibration environments
- Polarized housing (P) prevents reverse insertion and connector mating errors
- Tape-and-reel (TR) format compatible with standard pick-and-place SMT assembly equipment
- Dual-row layout maximizes signal density while maintaining 2.54 mm standard grid compatibility
What is TSM-127-02-SM-DH-P-TR used for?
TSM-127-02-SM-DH-P-TR is used in backplane interconnects, industrial control cards, and FPGA expansion boards where a 54-pin, 2.54 mm pitch dual-row SMT header is needed. The combination of through-hole retention tails and tape-and-reel packaging makes it an efficient choice for high-volume production lines in communications, embedded computing, and motion control systems.

Frequently Asked Questions
How many signal pins does TSM-127-02-SM-DH-P-TR provide and in what configuration?
TSM-127-02-SM-DH-P-TR offers 54 positions arranged in a dual-row format on a 0.100" (2.54 mm) pitch. This provides 54 pins for signals, power, and ground in a compact SMT footprint that fits standard 2.54 mm grid PCB designs used across industrial and computing platforms.
What mechanical advantage do the DH through-hole tails provide on a 54-pin surface-mount connector?
The DH suffix adds through-hole solder tails that pass through PCB vias alongside the SMT pads. For a large 54-position connector, these tails significantly improve mechanical retention, preventing connector lift-off under vibration or repeated mating cycles that would stress a pure surface-mount 0.100" pitch solder joint.
Why is the polarized housing important when selecting TSM-127-02-SM-DH-P-TR for a production board?
The P suffix denotes a polarized housing that has a physical key preventing the mating connector from being inserted in the wrong orientation. On a 54-pin, 2.54 mm pitch dual-row interface, a reverse insertion could cause shorts across 54 pins, making polarization a critical assembly error-proofing feature for production and field service.
How does TSM-127-02-SM-DH-P-TR fit into a long-term supply strategy for industrial control equipment?
SAMTEC's TSM series is an active product family with broad distributor coverage. The TR tape-and-reel format allows purchasing teams to plan volume buy quantities for production runs, and the 54-position 0.100" pitch variant is stocked by major distributors, reducing lead-time risk for industrial equipment with 5- to 10-year production lifespans requiring reliable 54-pin connector sourcing.
