What are the key features of TST-102-03-H-D?
- 4-position dual-row through-hole shrouded header with 0.100 inch (2.54 mm) pitch providing 4 contacts in a compact 0.5 inch x 0.365 inch footprint
- Gold (30 µin) over nickel contact finish ensures low contact resistance and long mating cycle life exceeding 500 insertion cycles
- Shrouded housing with male square-pin contacts provides keyed polarization to prevent incorrect mating orientation in field-service applications
- Rectangular contact pattern compatible with standard 2.54 mm pitch female socket connectors and IDC cable assemblies
What is TST-102-03-H-D used for?
The TST-102-03-H-D is used in test and measurement equipment, embedded development boards, and industrial interface cards where a reliable 4-contact dual-row through-hole header provides signal routing between PCB sub-assemblies and external harnesses. Its gold-plated contacts and shrouded housing ensure consistent electrical performance across hundreds of mating cycles in lab environments and production test fixtures. The 0.100 inch pitch and standard rectangular contact pattern make it directly compatible with common 4-pin female IDC cable assemblies and SIL socket connectors used in prototyping and sensor interface wiring.

Frequently Asked Questions
What contact finish does the TST-102-03-H-D use and how does it affect connector longevity?
The TST-102-03-H-D features gold (30 µin) plating over nickel on all mating contacts, providing corrosion resistance and maintaining low contact resistance below 20 mΩ across more than 500 mating cycles, making it suitable for test fixtures and development boards where connectors are frequently inserted and removed.
What are the physical dimensions of the TST-102-03-H-D and how many contacts does it provide?
The TST-102-03-H-D has a body length of 0.5 inch and body breadth and depth of 0.365 inch, with 4 male square-pin contacts arranged in a dual-row 0.100 inch pitch pattern. The compact footprint requires only 4 through-holes in a 2x2 grid with 2.54 mm spacing.
Which cable assemblies are compatible with the TST-102-03-H-D for quick prototype wiring?
The TST-102-03-H-D male header with 0.100 inch (2.54 mm) pitch is compatible with standard 4-pin female IDC ribbon cable connectors, DuPont-style female socket harnesses, and 2x2 female SIL socket connectors, all of which are widely available in 28 AWG to 24 AWG wire gauges for signal and low-power connections up to 1 A per contact.
When should a designer choose the shrouded TST-102-03-H-D over an unshrouded 4-pin header?
The shrouded housing of the TST-102-03-H-D provides a keying feature that prevents a mating 4-pin cable connector from being installed rotated 180 degrees, which is critical for connections carrying polarized signals such as I2C, SPI, or power/ground pairs where reverse insertion could damage ICs or cause incorrect voltage application to sensitive 3.3 V or 5 V logic circuits.
