What are the key features of TST-102-01-G-D?
- 4-position dual in-line 0.100" pitch layout (2x2) provides compact square footprint of 0.5" x 0.365" for high-density PCB designs
- 10µin gold over 50µin nickel mating contact finish ensures low contact resistance and excellent corrosion resistance over hundreds of mating cycles
- Gold (Au) over Nickel (Ni) termination finish on through-hole pins provides reliable solder joint integrity in wave and hand soldering processes
- RoHS-compliant (Pb-free) construction meets global environmental regulations for green electronics manufacturing
- Short 2-week factory lead time reduces procurement delays for prototype and production schedules
What is TST-102-01-G-D used for?
The TST-102-01-G-D is used in test and measurement equipment, debugging interfaces, and compact board-to-board interconnects where a 4-pin dual in-line 0.100" pitch through-hole connector is needed with high-quality gold contact plating. Its 2x2 layout fits naturally into JTAG and SWD debug header pinouts and is compatible with standard 0.100" pitch ribbon cable IDC connectors and crimp socket housings. The connector is also suitable for low-voltage signal lines on industrial control boards, sensor interface PCBs, and laboratory instrument front-ends requiring reliable repeated mating in engineering test environments.

Frequently Asked Questions
How does the 10µin gold contact finish on TST-102-01-G-D compare to standard tin-plated alternatives for high-cycle test applications?
The TST-102-01-G-D uses 10µin gold over 50µin nickel on mating contacts, providing a contact resistance typically below 20mΩ and sustaining this performance over 500 or more mating cycles before measurable wear. Standard tin-plated connectors typically guarantee only 30 to 50 mating cycles before tin oxidation can increase contact resistance above acceptable levels. This makes the gold-plated TST-102-01-G-D the correct choice for test fixtures, board-level debug headers, and any application where repeated insertion and removal is expected.
What PCB footprint does the TST-102-01-G-D require, and how does it fit into a 0.100" grid design?
The TST-102-01-G-D uses a 2x2 dual in-line arrangement on a 0.100" (2.54mm) grid, requiring 4 through-holes in a square pattern measuring 0.100" x 0.100" between adjacent pins. The connector body is 0.5" long x 0.365" wide x 0.365" deep, fitting within a 13mm x 9.3mm keepout area on the PCB. This standard 0.100" pitch footprint is compatible with all major EDA tools including Altium Designer, KiCad, and Eagle, and aligns with both 0.100" pitch breadboard grids and standard ribbon cable IDC connectors.
For a compact sensor interface board needing 4-pin dual in-line connectivity, how does TST-102-01-G-D compare to a single-row 4-pin header?
The TST-102-01-G-D in 2x2 dual in-line configuration occupies a square 0.1" x 0.1" pin field (approximately 2.54mm between each pair), making it roughly 50% shorter in one board dimension compared to a 1x4 single-row header spanning 0.3" (7.62mm). This compact square footprint is advantageous on sensor breakout boards, JTAG/SWD debug headers, and SPI/I2C interface connectors where board width is constrained to under 20mm. The 2x2 layout also mechanically resists connector rotation during mating, improving alignment reliability over single-row alternatives.
What cable assemblies mate with the TST-102-01-G-D, and what current capacity should be planned per pin?
The TST-102-01-G-D mates with SAMTEC's TCSD (Micro-D style) or standard 0.100" pitch female crimp socket housings loaded with 24 AWG to 28 AWG wire crimp contacts, as well as 4-conductor 0.100" pitch IDC ribbon cable assemblies. Each contact is rated for approximately 1A continuous current at 25°C ambient, giving the 4-pin connector a total current capacity of 4A when all pins carry current — suitable for mixed signal-and-power configurations such as a 2-pin power rail at 2A combined with 2 signal lines in a sensor node power connector.
