Key Features
- 38-position dual-row layout on 0.100 inch (2.54 mm) pitch offering high contact density for SMT board-to-board signal interfaces
- Top-mount (TM) SMT termination style allows placement on the top PCB surface with low standoff, simplifying single-reflow assembly
- Tape-and-reel (TR) packaging with dual-row (DH) body enabling automated pick-and-place at production volumes with standard EIA-481 feeders
Applications
The TSM-119-04-TM-DH-A-K-TR is ideal for high-density signal distribution in embedded computing, industrial I/O expansion cards, and communications backplanes where 38 contacts must be routed on standard 0.100 inch pitch. Its top-mount SMT tails support single-pass reflow assembly without the need for secondary wave solder or through-hole drilling. The tape-and-reel format enables consistent automated placement at production rates required for medium- to high-volume electronics manufacturing.

Frequently Asked Questions
What is the contact count and pitch of the TSM-119-04-TM-DH-A-K-TR, and how does it affect board layout?
The TSM-119-04-TM-DH-A-K-TR has 38 contacts arranged in a dual-row format on 0.100 inch (2.54 mm) pitch, with 19 contacts per row. This standard pitch is compatible with common 0.100 inch dual-row PCB footprints, allowing straightforward integration into existing board layouts without custom pad redesign.
How does the top-mount termination style of the TSM-119-04-TM-DH-A-K-TR simplify PCB manufacturing?
Top-mount (TM) SMT tails lie flat against the PCB top layer pads and reflow with standard solder paste, eliminating through-hole drilling and secondary wave solder operations. This reduces fabrication steps, lowers PCB cost, and enables all 38 contacts to be soldered in a single reflow pass alongside other SMT components.
For which industrial or computing applications is the TSM-119-04-TM-DH-A-K-TR commonly specified?
This connector is commonly specified in PLC I/O modules, industrial Ethernet switches, and embedded ARM or FPGA computing boards where 38 signal lines at 0.100 inch pitch provide sufficient I/O bandwidth. Its dual-row body keeps the connector footprint narrow, leaving adequate routing clearance for adjacent high-speed differential pairs and power planes.
What are the packaging and ordering considerations for the TSM-119-04-TM-DH-A-K-TR in a production build?
The TR suffix confirms tape-and-reel packaging, typically supplied in reels of 250 to 500 pieces. Procurement in reel quantities reduces per-unit cost versus cut-tape and ensures uninterrupted feeder operation during long SMT production runs, minimizing downtime on lines assembling several thousand boards per shift.
