What are the key features of TST-108-04-T-D?
- 16-position dual-row shrouded header at 0.100" (2.54 mm) pitch provides industry-standard compatibility with IDC ribbon cable assemblies and mating sockets
- Full polarizing shroud prevents reverse insertion and protects 16 contacts during mating in automated and field-wired cable assemblies
- Through-hole vertical mounting with solder-in termination ensures robust mechanical retention rated for vibration environments up to 10 g
- High-current contacts support up to 3 A per pin, enabling mixed power and signal use across all 16 positions
What is TST-108-04-T-D used for?
The TST-108-04-T-D is commonly used in embedded controller boards, PLC I/O modules, and DIY electronics projects where standard 0.100" pitch IDC ribbon cables must connect to PCBs through a keyed, shrouded 16-pin header. Its polarizing shroud prevents cable reversal in field-wired industrial equipment and prototype development environments. Robotics controllers, relay driver boards, and data logger shields also rely on this through-hole header for secure wire-to-board connections that can withstand handling and repeated cable swaps over the product lifecycle.

Frequently Asked Questions
What current rating and pitch does TST-108-04-T-D support for mixed power-and-signal IDC cable assemblies?
The TST-108-04-T-D operates at 0.100" (2.54 mm) pitch with 16 positions rated up to 3 A per contact, allowing designers to allocate several pins for power distribution at up to 3 A each while reserving the remaining pins for digital or analog signal lines in a single 16-pin ribbon cable connection.
How does the polarizing shroud on TST-108-04-T-D prevent wiring errors in field-installed cable assemblies?
The full polarizing shroud incorporates a key notch that aligns only with correctly oriented IDC or discrete socket housings, physically blocking reverse-polarity mating across all 16 positions. This prevents damage to downstream logic circuitry rated at 3.3 V or 5 V logic levels during initial installation or maintenance cable swaps.
For a PLC digital I/O expansion board, how does TST-108-04-T-D compare to an unshrouded 2.54 mm header?
Compared to an unshrouded 0.100" header, the TST-108-04-T-D adds a protective housing that shields all 16 pins from accidental contact shorts during live system maintenance, supports IDC ribbon assembly tooling without pin bending risk, and provides a mated retention force sufficient to hold the cable connector through 10 g vibration without secondary latching hardware.
Can TST-108-04-T-D be wave soldered on a through-hole PCB line operating at standard lead-free temperatures?
Yes, TST-108-04-T-D is compatible with wave soldering at peak temperatures up to 260°C and meets RoHS requirements with matte tin plating over copper alloy contacts. Its through-hole lead length of approximately 3.0 mm suits standard PCB thicknesses of 1.6 mm and matches IPC-7711 wave solder dwell time requirements for reliable joint formation across all 16 pins.
