What are the key features of TSM-123-02-TL-DH-A-K-TR?
- 46-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch and extended tail-length (TL) termination for deeper solder joint penetration
- DH (dual-row high-profile) body providing 8 mm to 11 mm standoff clearance for stacked board assembly with component clearance between boards
- Tape-and-reel packaging enabling reliable high-volume automated pick-and-place SMT assembly across 46 positions
What is TSM-123-02-TL-DH-A-K-TR used for?
The TSM-123-02-TL-DH-A-K-TR is used in applications requiring robust 46-position dual-row SMT connections with extended solder tails, such as FPGA daughter boards, embedded computing backplanes, and industrial control expansion interfaces. The tail-length (TL) design provides deeper pad engagement for improved solder joint strength in vibration-prone environments like transportation and industrial automation equipment. Tape-and-reel packaging suits high-volume automated SMT production.

Frequently Asked Questions
How does the TL (tail-length) termination style of TSM-123-02-TL-DH-A-K-TR improve PCB mounting?
The TL (tail-length) variant features extended contact tails that penetrate deeper into SMT solder pads compared to standard terminations. This extended engagement increases solder joint cross-sectional area, improving shear and pull-out strength — beneficial in applications exposed to vibration and shock, such as industrial machinery and transportation equipment operating at temperatures from -40°C to +85°C.
What is the total pin count and row configuration of the TSM-123-02-TL-DH-A-K-TR?
The TSM-123-02-TL-DH-A-K-TR provides 46 total contact positions arranged in 2 rows of 23, at a 0.100" (2.54 mm) pitch. This configuration enables simultaneous routing of 46 signals or power lines in a compact dual-row SMT footprint, suitable for dense backplane and mezzanine interface designs in embedded and industrial systems.
When would you select the TSM-123-02-TL-DH-A-K-TR over the TSM-123-03-F-DH-A-K-TR for the same 46-pin interface?
The TL (tail-length) variant (02-TL) is preferred when mechanical solder joint robustness is critical, such as in vibration-prone or high-shock environments, because longer tails provide a larger solder fillet. The standard tail (03-F) variant suits applications prioritizing minimal board thickness and standard reflow profiles, typically on 1.6 mm PCBs with 0.5 mm pad depths.
Which socket connectors mate reliably with the TSM-123-02-TL-DH-A-K-TR?
The TSM-123-02-TL-DH-A-K-TR mates with SAMTEC's SSM or SSW series 0.100" (2.54 mm) dual-row socket strips in the matching 23-position-per-row configuration. These pairs support individual contact current ratings up to 2 A and are rated for operating temperatures from -55°C to +125°C, suitable for industrial, embedded, and communications environments.
