What are the key features of TST-102-01-T-D?
- 4-position dual-row shrouded header at 0.100 inch (2.54 mm) pitch for standard cable mating
- Tin-over-nickel (200 µin) contact finish for corrosion resistance and reliable low-resistance mating
- Male square-pin contacts compatible with standard 0.100 inch cable socket housings
- Shrouded body providing mechanical protection and polarized mating to prevent misinsertion
- Compact PCB footprint with 0.5 inch body length suitable for space-constrained board layouts
What is TST-102-01-T-D used for?
The TST-102-01-T-D is widely used in embedded microcontroller boards, industrial I/O modules, and prototype development harnesses where a 4-position 0.100 inch pitch shrouded header is needed for secure cable-to-board signal routing. Its shrouded polarized housing prevents incorrect cable insertion in applications where multiple identical headers are placed near each other on the PCB. Engineers also use this connector in JTAG debug interfaces, sensor signal breakout boards, and power distribution headers requiring reliable tin-over-nickel contact integrity.

Frequently Asked Questions
What contact finish does the TST-102-01-T-D use and why does it matter for signal integrity?
The TST-102-01-T-D uses a tin over nickel contact finish, with tin plating approximately 200 microinches thick over a nickel barrier layer. This finish provides good corrosion resistance and maintains low contact resistance over multiple mating cycles, making it suitable for signal connections in industrial and embedded environments where gold plating is not cost-justified.
How does the shrouded housing of the TST-102-01-T-D prevent wiring errors in multi-connector PCB designs?
The polarized shroud on the TST-102-01-T-D mechanically constrains the mating cable socket so it can only engage in one orientation. In PCB layouts with multiple 4-pin 0.100 inch headers placed close together, this keyed shroud prevents cross-mating between adjacent connectors, which is a common source of field wiring errors in industrial control and embedded system prototyping.
What is the body size of the TST-102-01-T-D and how does it fit into compact PCB layouts?
The TST-102-01-T-D has a body measuring 0.5 inch long by 0.365 inch deep by 0.365 inch wide. This compact footprint allows 4-position dual-row headers to be placed with minimal board area impact, making the connector appropriate for embedded modules and sensor breakout boards where PCB real estate is limited.
For which debug and programming interfaces does the TST-102-01-T-D connector format commonly appear?
The 4-position 0.100 inch pitch dual-row shrouded header format of the TST-102-01-T-D is commonly used for SWD (Serial Wire Debug) and UART debug connectors on ARM Cortex microcontroller development boards, where a 4-pin interface carries SWDIO, SWDCLK, GND, and VCC at 3.3V or 5V logic levels with a keyed housing to prevent reverse insertion during active debugging sessions.
