What are the key features of TSM-123-02-L-DH-A-K-TR?
- 46-position dual-row 0.100" (2.54 mm) pitch layout offers broad I/O capacity on a standard grid for development boards and backplane connectors
- Low-profile (L) lead style minimizes connector height above the PCB surface, supporting compact stacked board assemblies and space-constrained enclosures
- Tape-and-reel (TR) packaging in EIA-481 compatible carrier tape enables high-throughput automated SMT pick-and-place assembly
What is TSM-123-02-L-DH-A-K-TR used for?
TSM-123-02-L-DH-A-K-TR is well suited for I/O expansion headers on embedded processor boards, bus interface terminal strips on industrial control backplanes, and signal distribution connectors in test-and-measurement rack systems. Its 46-position dual-row 0.100" pitch design provides 23 positions per row in a footprint compatible with standard 0.1" grid PCB layouts, supporting digital signal, power distribution, and mixed-signal interfaces in compact enclosure-mounted assemblies.

Frequently Asked Questions
What does the low-profile lead designation mean for the TSM-123-02-L-DH-A-K-TR and how does it affect board height?
The L designation specifies a low-profile lead form that reduces the connector's stand-off height above the PCB compared to standard lead styles. SAMTEC TSM series low-profile variants typically achieve a body height of under 3.5 mm above the board surface, enabling mated stack assemblies with sub-10 mm total height when paired with a matching dual-row socket, which benefits compact industrial control enclosure designs.
How many signals can TSM-123-02-L-DH-A-K-TR carry and what current rating applies per contact?
The TSM-123-02-L-DH-A-K-TR provides 46 total positions, 23 per row, at 0.100" (2.54 mm) dual-row pitch. Each contact is rated at 3 A current capacity, consistent with SAMTEC TSM series specifications, allowing multiple adjacent pins to be ganged for higher current supply rails while using remaining contacts for signal lines in mixed-signal interface designs.
When is TSM-123-02-L-DH-A-K-TR a preferred alternative to a 50-position version of the same series?
Designers choose the 46-position TSM-123-02-L-DH-A-K-TR when 46 I/O lines match their actual signal count, avoiding the extra 4 positions and approximately 10.16 mm (4 × 2.54 mm) of additional board length that a 50-position version would require. In compact PCBs where connector length along one edge is limited to about 60 mm, the 46-position strip spanning roughly 58.42 mm fits where the 50-position strip at 127 mm would not.
Does TSM-123-02-L-DH-A-K-TR support lead-free reflow and what temperature range is it rated for?
Yes, TSM-123-02-L-DH-A-K-TR is designed for surface-mount lead-free reflow assembly at peak temperatures up to 260°C, meeting J-STD-020 MSL requirements for standard SMT processing. The connector is rated for continuous operation from -55°C to +125°C, making it suitable for commercial, industrial, and light automotive-adjacent applications requiring reliable 46-pin board connection across wide operating temperature ranges.
