What are the key features of TST-110-04-F-D?
- 20-pin dual-row shrouded PCB header at 0.100-inch (2.54 mm) standard pitch enabling broad compatibility with common IDC ribbon cable and discrete wire connectors
- Female (F) contact configuration provides recessed pin protection within the shroud, reducing risk of pin damage during handling and cable assembly operations
- Dual-row polarized shroud enforces a single valid mating orientation, preventing reverse insertion errors that could damage 5 V or 3.3 V logic signals on adjacent pins
What is TST-110-04-F-D used for?
The TST-110-04-F-D shrouded PCB header is used in embedded single-board computers, industrial control panels, and data acquisition systems where a polarized 20-pin dual-row connector is needed to ensure correct cable attachment to I/O expansion or ribbon cable assemblies. Its standard 0.100-inch pitch supports direct mating with off-the-shelf 20-pin IDC cable assemblies, reducing custom cable tooling costs. The through-hole mounting style provides robust mechanical retention suitable for equipment subject to handling vibration and repeated cable connection cycles.

Frequently Asked Questions
How many pins does the TST-110-04-F-D provide, and how does the dual-row layout compare to a single-row 20-pin header in board area?
The TST-110-04-F-D provides 20 pins in a dual-row configuration with 10 contacts per row at 0.100-inch (2.54 mm) pitch. The dual-row layout spans only 0.9 inch in length compared to a single-row 20-pin header which would measure 1.9 inches, making the dual-row version more than 50% shorter and freeing significant board space in compact I/O panel designs.
For a parallel data bus interface on an embedded control board, why would a designer choose the female-contact TST-110-04-F-D over a male-pin header?
The female (F) contact variant of the TST-110-04-F-D positions the electrical contacts recessed inside the shroud, protecting all 20 signal pins from accidental shorting or mechanical damage during PCB handling and cable attachment. This is especially important when the connector is located on a PCB edge or panel where technician contact is likely, and it is the standard choice for mating with male-pin IDC ribbon cable assemblies that carry 8-bit or 16-bit parallel data buses.
What ribbon cable assemblies mate directly with the TST-110-04-F-D, and what data rates does the 0.100-inch pitch support?
The TST-110-04-F-D mates directly with standard 20-pin IDC ribbon cable assemblies using 0.100-inch (2.54 mm) pitch flat cable, available from multiple cable assembly suppliers without custom tooling. At 0.100-inch pitch, the connector supports signal data rates up to several hundred MHz for unshielded parallel signals, adequate for common microcontroller peripheral buses, GPIO expansion, and low-speed parallel data acquisition in the 1 MHz to 50 MHz range.
Is the TST-110-04-F-D readily available for production procurement, and how can engineers verify stock before ordering?
The TST-110-04-F-D is supported through SAMTEC's global distribution network with Tiger Buy stocking options providing lead times as short as 1 week. Engineers can check real-time inventory across authorized distributors using standard distributor inventory search tools or SAMTEC's own e-commerce portal, which also supports same-day shipping for in-stock quantities. For production orders requiring 500 or more pieces, blanket purchase orders with scheduled deliveries are recommended given the 0.100-inch pitch shrouded header market demand.
