- Gold flash (3 µin) over nickel mating contacts for low contact resistance and extended insertion cycle life
- Shrouded housing with rectangular pin-socket contact pattern preventing mis-mating in field-installed assemblies
- Tin-over-nickel termination finish compatible with standard wave and selective solder PCB assembly processes
What is TST-104-02-F-D used for?
The TST-104-02-F-D is used for PCB-to-PCB or wire-to-board interconnects in embedded systems, test and measurement equipment, and industrial control boards requiring reliable 8-position dual-row connections. Its shrouded 0.100" pitch header guides mating connectors precisely, reducing installation errors in field-service scenarios and automated test fixtures. The gold-flashed contacts provide consistent low resistance across multiple mating cycles, supporting high-reliability applications in telecommunications and medical instrumentation.

Frequently Asked Questions
What contact finish does the TST-104-02-F-D use, and how does it affect connector reliability over many mating cycles?
The TST-104-02-F-D uses gold flash (3 µin minimum) over nickel on its mating contacts, providing corrosion resistance and stable, low contact resistance across repeated insertions. This finish is well-suited for test fixtures and development boards where connectors may be mated and unmated dozens of times, with the nickel barrier layer protecting against gold diffusion into the tin termination.
How does the shrouded housing of the TST-104-02-F-D improve connection accuracy compared to an unshrouded header?
The TST-104-02-F-D's plastic shroud physically aligns the mating connector over all 8 positions on the 0.100" (2.54 mm) dual-row pattern, eliminating offset insertion that can bend pins or create open circuits. In rack-mounted or field-serviceable equipment where technicians work under restricted access, the shroud reduces mis-mating incidents and protects the male contacts from mechanical damage.
What are the body dimensions of the TST-104-02-F-D, and how much PCB area does it require?
The TST-104-02-F-D body measures 0.700 inch in length, 0.365 inch in breadth, and 0.365 inch in depth, occupying roughly 0.26 square inches of PCB footprint. This compact outline fits on constrained layouts typical of embedded controller boards and test fixture modules, while the dual-row 8-position layout maximizes signal density within that area.
In which application scenarios is the TST-104-02-F-D preferred over a FFC/FPC connector for board-level interconnects?
Where ruggedness and repeated mating durability matter more than cable flexibility, the TST-104-02-F-D is preferred over FFC/FPC connectors. At 0.100" pitch with gold-flashed square pin contacts, it handles higher current per position and withstands vibration better, making it the right choice for industrial automation modules, bench-top test equipment, and embedded computing boards subject to mechanical stress or thermal cycling.
