What are the key features of TST-111-03-T-D?
- 22-position dual-row shrouded housing at 0.100 inch (2.54 mm) pitch prevents mis-mating in polarized PCB assemblies
- Tin-over-nickel contact finish on both mating and termination surfaces ensures reliable electrical contact and corrosion resistance
- Square pin socket-style (SQ PIN-SKT) male contact design provides robust mechanical engagement with standard 0.100 inch pitch female connectors
What is TST-111-03-T-D used for?
The TST-111-03-T-D is a 22-position shrouded PCB header suited for ribbon cable interfaces and board-to-board connections in industrial control systems, embedded computing modules, and test fixtures. Its 0.100 inch pitch and dual-row configuration support standard IDC cable assemblies and internal wiring harnesses in automation and instrumentation equipment. The shrouded design ensures correct orientation during cable attachment, reducing field assembly errors in systems requiring frequent maintenance.

Frequently Asked Questions
What body dimensions does the TST-111-03-T-D have and how does that affect PCB layout?
The TST-111-03-T-D has a body length of 1.4 inches and a body breadth and depth of 0.365 inches. This compact footprint at 0.100 inch (2.54 mm) pitch allows a 22-position dual-row header to fit in a PCB area of approximately 35 mm by 9.3 mm, making it practical for embedded controller boards, breakout modules, and test fixture PCBs with moderate connector density requirements.
How does the shrouded housing of the TST-111-03-T-D reduce connection errors in field-assembled systems?
The shrouded housing on the TST-111-03-T-D physically polarizes the 22-position dual-row connector, preventing incorrect cable orientation during ribbon cable or IDC assembly attachment. In industrial control panels and embedded systems with 0.100 inch pitch wiring, a mis-seated connector can pass voltages to wrong pins, damaging circuits. The shroud reduces this risk by requiring correct physical alignment before insertion, which is particularly valuable in systems where technicians connect cables without PCB schematics.
When is TST-111-03-T-D a practical choice compared to a connector with gold-plated contacts?
The TST-111-03-T-D uses a tin-over-nickel contact finish rather than gold, making it more cost-effective for applications requiring fewer than 100 mating cycles and operating at signal currents below 3 A per pin. In industrial control wiring and embedded system prototyping where connectors are mated once or infrequently, the tin finish provides adequate contact resistance below 30 milliohms at a lower unit cost than gold-plated alternatives.
