What are the key features of TSM-125-03-L-DH-A-K-TR?
- 50-position dual-row layout at 0.100" (2.54 mm) pitch supporting wide parallel bus and high pin-count SMT interconnects
- Low-profile 'L' mounting designation minimizes above-board height for slim PCB assemblies and stacked board designs
- Tape-and-reel (TR) supply format compatible with automated pick-and-place machines for high-volume production
What is TSM-125-03-L-DH-A-K-TR used for?
The TSM-125-03-L-DH-A-K-TR is applied in FPGA evaluation boards, industrial automation controllers, and embedded computing modules requiring 50-pin parallel interfaces in a surface mount low-profile package. Its dual-row 0.100" pitch design supports full 32-bit address or data bus connections plus additional control lines within a single connector. The low-profile height makes it well suited for compact enclosures where board clearance is limited to fewer than 5 mm.

Frequently Asked Questions
How does TSM-125-03-L-DH-A-K-TR differ from TSM-125-03-LM-DH-A-K-TR in mounting profile height?
Both connectors provide 50 positions at 0.100" (2.54 mm) pitch with a low-profile design, but the 'L' variant typically features a slightly different height specification compared to the 'LM' (low-profile with extended mating) variant. The 'LM' designation usually adds an additional few tenths of a millimeter to accommodate a longer mating zone, while 'L' maintains the shortest possible profile, typically under 3.5 mm above the PCB.
Which processor or FPGA bus interfaces commonly use a 50-position connector like TSM-125-03-L-DH-A-K-TR?
A 50-position dual-row connector suits full 32-bit data bus interfaces (32 data + 8 address + 10 control lines), JTAG boundary scan chains daisy-linked through 50-pin headers, and legacy ISA-style expansion buses. FPGA development boards frequently use 50-pin headers to expose GPIO banks of 48 signals plus 2 power pins through a single TSM-125 footprint.
For a PCB with 1.6 mm board thickness, can TSM-125-03-L-DH-A-K-TR solder cleanly without mechanical stress?
Yes, the TSM-125-03-L-DH-A-K-TR is engineered for SMT placement on standard 1.6 mm FR4 PCB substrates. The SMT pads contact only the top copper layer, so no through-hole clearance is required. The housing maintains coplanarity within 0.1 mm across the 50-position length, ensuring all pads contact the solder paste during reflow at 260°C peak temperature.
How should a procurement engineer verify TSM-125-03-L-DH-A-K-TR stock availability for a production build of 10,000 units?
Procurement teams should confirm tape-and-reel quantities directly with Samtec authorized distributors, as the '-TR' suffix guarantees the part ships on 7-inch or 13-inch reels typically containing 250 to 1,000 parts each. For a 10,000-unit build requiring 10,000 connectors, plan for 10 to 40 reels and request factory lead times of 4 to 8 weeks if distributor stock is below the required quantity.
