What are the key features of TSM-127-01-T-DH-A-K-TR?
- 54-position single-row layout at 0.100" (2.54 mm) pitch for broad PCB signal routing compatibility
- Through-hole-style (T) SMT termination provides superior solder joint strength and board retention
- Dual-height keyed shroud (DH-K) enforces correct polarization and prevents reversed mating on all 54 pins
- Gold-plated contacts (A finish) for stable, low-resistance electrical connections across repeated cycles
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly at production volumes
What is TSM-127-01-T-DH-A-K-TR used for?
SAMTEC TSM-127-01-T-DH-A-K-TR is used in industrial automation, embedded computing, and backplane distribution boards where a reliable 54-position keyed SMT terminal strip is required at the standard 0.100-inch pitch. The through-hole-style solder tail provides additional mechanical anchorage to the PCB, making this connector particularly well-suited for applications subject to vibration or repeated connector mating cycles.

Frequently Asked Questions
How does the through-hole-style termination on TSM-127-01-T-DH-A-K-TR improve mechanical strength versus standard SMT tails?
The -T suffix designates a through-hole-style termination where SMT solder tails pass through PCB vias before reflowing, dramatically increasing pull-out strength compared to surface-only SMT pads. For a 54-position connector this extra mechanical anchorage is valuable in applications with vibration or frequent mating cycles.
Does the keyed shroud on TSM-127-01-T-DH-A-K-TR reduce rework costs in production?
Yes. The dual-height keyed shroud (DH-K) physically blocks reversed insertion on all 54 pins, preventing the board damage that requires costly rework. Keying is especially effective in high-mix automated assembly where operators or robots might otherwise insert the same-looking 0.100-inch pitch connector backwards.
Which test or instrumentation applications benefit most from the gold contacts on TSM-127-01-T-DH-A-K-TR?
Test fixtures, functional testers, and lab instrumentation benefit most from the gold contact finish (A designation) on TSM-127-01-T-DH-A-K-TR, as gold maintains a stable and low contact resistance across hundreds of mating cycles without the oxidation that degrades tin-plated contacts in similar 54-pin interconnect roles.
What are the stocking and lead time options for TSM-127-01-T-DH-A-K-TR in production order quantities?
Standard SAMTEC TSM catalog parts in tape-and-reel format typically have lead times of 1 to 3 weeks from stock for standard quantities. For production orders above 2,000 pieces of the 54-position TSM-127-01-T-DH-A-K-TR, buyers should contact SAMTEC or an authorized distributor to confirm factory scheduling and pricing.
