What are the key features of TST-108-04-G-D?
- 16-position dual-row shrouded header on standard 0.100 inch (2.54 mm) pitch for secure, keyed wire-to-board connections
- Integrated polarizing shroud prevents mis-mating and protects pin contacts during repeated connector insertions in field environments
- Through-hole mounting with gold-plated contacts ensures low contact resistance and long service life across industrial temperature ranges
What is TST-108-04-G-D used for?
The TST-108-04-G-D is used in board-to-wire harness interfaces for industrial control panels, embedded development boards, and prototyping systems where 16 keyed signal connections are needed on a 0.100 inch pitch. Its shrouded design is well suited for field-serviced equipment where accidental mis-insertion must be prevented. The standard 2.54 mm pitch ensures broad compatibility with IDC ribbon cables and common crimp-style housings.

Frequently Asked Questions
How many positions does the TST-108-04-G-D have and what row configuration does it use?
The TST-108-04-G-D is a 16-position shrouded PCB header arranged in 2 rows of 8 pins each on a 0.100 inch (2.54 mm) pitch. The dual-row layout suits applications needing moderate signal counts in a compact through-hole footprint, and the shroud ensures correct polarization during mating with compatible IDC or crimp housings.
Why choose a shrouded header like the TST-108-04-G-D over an unshrouded pin strip for industrial cable connections?
A shrouded header physically encloses all 16 pins inside a plastic housing, which prevents accidental contact with adjacent pins and ensures the mating connector can only be inserted in the correct orientation. In industrial environments where cables are frequently disconnected for maintenance, this keying feature eliminates the risk of a reversed-polarity connection that could damage sensitive logic or power circuits on the PCB.
What cable assemblies are compatible with the TST-108-04-G-D's 0.100 inch pitch and 16-pin dual-row layout?
Standard 16-conductor IDC ribbon cable assemblies terminated in a 2x8 IDC connector on a 0.100 inch (2.54 mm) pitch mate directly with the TST-108-04-G-D. Crimp-style housings from SAMTEC's IDSS or comparable 2x8 connector families on 2.54 mm pitch are also compatible, giving designers flexibility to use either ribbon or discrete-wire harness solutions for their cable interconnect.
What contact finish does the TST-108-04-G-D use, and how does it affect long-term signal reliability?
SAMTEC's TST series headers use gold-plated contacts on the mating interface, typically 0.000030 inch (30 microinches) minimum gold over nickel underplate. Gold plating provides corrosion resistance and maintains low and stable contact resistance below 20 milliohms even after hundreds of mating cycles, which is important for reliable signal transmission in instrumentation and control wiring harnesses.
