Key Features
- 40-position dual-row shrouded PCB header with 0.100" (2.54mm) pitch for high-density board-to-board connections
- Gold (10µin) over nickel contact finish on both mating and termination surfaces for corrosion resistance and low contact resistance
- Shrouded design provides mechanical keying and protects pins during mating, reducing misalignment risk
- RoHS-compliant (Pb-free) construction suitable for lead-free assembly processes
Applications
The TST-120-02-G-D is well suited for board-to-board and wire-to-board interconnects in industrial control systems, test and measurement equipment, and embedded computing platforms requiring reliable 40-pin dual-row connections. Its shrouded 0.100" pitch design makes it ideal for compact PCB layouts where positive connector alignment is critical, such as backplane systems, data acquisition modules, and prototyping boards. Engineers also deploy this header in robotics, automation controllers, and communication equipment where gold-contact reliability and Pb-free compliance are required.

Frequently Asked Questions
What is the pin pitch and row configuration of the TST-120-02-G-D?
The TST-120-02-G-D features a 0.100" (2.54mm) pitch dual-row configuration with 40 total positions (20 per row), making it compatible with standard 0.100" mating connectors and ribbon cable assemblies commonly used in PCB interconnect systems.
Which applications benefit most from the TST-120-02-G-D shrouded header design?
The shrouded housing guides mating connectors into alignment, making TST-120-02-G-D ideal for backplane systems, industrial controllers, and test fixtures where blind mating or repeated connect-disconnect cycles occur across 40 pins at 2.54mm pitch.
What contact finish does TST-120-02-G-D use, and why does it matter for reliability?
TST-120-02-G-D uses gold (10µin minimum) over a nickel barrier on both mating and termination contacts. This gold finish delivers contact resistance below 20 mΩ and withstands hundreds of mating cycles, critical for test equipment and field-service connectors.
Is the TST-120-02-G-D RoHS compliant and suitable for lead-free PCB assembly?
Yes, TST-120-02-G-D carries a Pb-free (RoHS) code, meaning it is manufactured without restricted hazardous substances and is fully compatible with SAC305 solder reflow processes at peak temperatures up to 260°C used in modern lead-free assembly lines.
