Key Features
- 8-position dual-row terminal strip with 2.54 mm (0.100 inch) pitch for universal breadboard and PCB compatibility
- Matte tin contact finish with nickel barrier providing low contact resistance and corrosion resistance over thousands of mating cycles
- Surface-mount termination style enabling reflow assembly without through-hole drilling
- Male square-pin contacts compatible with a wide range of female socket and IDC connectors
Applications
The SAMTEC TSM-104-02-T-DH-P-TR is used in development boards, evaluation modules, and production PCBs where a compact 8-pin dual-row 0.100-inch-pitch connector is needed for signal routing or daughter-card attachment. Its surface-mount footprint simplifies assembly on both prototype and high-volume production lines. Engineers also deploy it in test fixtures, FPGA breakout boards, and modular industrial I/O panels requiring reliable multi-pin header connections at standard 2.54 mm spacing.

Frequently Asked Questions
What is the contact pitch and pin count of the SAMTEC TSM-104-02-T-DH-P-TR, and which mating connectors are compatible?
The TSM-104-02-T-DH-P-TR has a 2.54 mm (0.100 inch) contact pitch with 8 positions arranged in a dual-row (4 × 2) configuration. This standard pitch is compatible with a wide range of female socket connectors, IDC ribbon cable connectors, and 0.100-inch-pitch jumper housings from SAMTEC and other manufacturers. The 2.54 mm grid makes it directly interchangeable with breadboard-standard headers, simplifying prototyping and test fixture integration.
How does the matte tin finish with nickel barrier on the TSM-104-02-T-DH-P-TR affect long-term contact reliability?
The matte tin (Sn) contact finish with an underlying nickel (Ni) barrier provides two key reliability benefits: the nickel layer prevents tin diffusion into the copper contact base, maintaining contact resistance below 30 mΩ over extended use, while the matte tin surface resists fretting corrosion from vibration-induced micro-motion. This dual-layer finish supports rated mating cycle counts of 30 or more insertions while remaining compatible with lead-free solder processes at up to 260°C peak reflow temperatures.
What PCB footprint dimensions does the TSM-104-02-T-DH-P-TR require, and how does the surface-mount style affect placement?
The connector body measures 0.40 inch long × 0.41 inch deep × 0.24 inch wide (approximately 10.2 mm × 10.4 mm × 6.1 mm). The surface-mount termination style means contacts land on the PCB surface rather than passing through drilled holes, allowing finer PCB stackup control and enabling placement on both sides of the board. Paste-in-hole or standard SMT reflow processes both apply, and the -TR suffix indicates the part ships in tape-and-reel format for automated pick-and-place assembly.
When should a designer select the TSM-104-02-T-DH-P-TR over a through-hole dual-row header for the same 8-pin connection?
Designers should prefer the TSM-104-02-T-DH-P-TR when the PCB requires full SMT assembly without through-hole drilling, which reduces board fabrication cost on thin or multi-layer PCBs where via-in-pad is restricted. The surface-mount style also yields lower profile height than a through-hole header with long tails, saving up to 3 mm of vertical clearance in height-constrained enclosures. Through-hole headers remain preferable only when mechanical pull-out strength exceeding 10 N per pin is required for repeated cable mating under stress.
