What are the key features of TST-104-05-L-D?
- Dual-row 8-position layout on 0.100" (2.54 mm) pitch for high-density connectivity
- Shrouded housing provides polarized mating to prevent mis-insertion during assembly
- Through-hole solder tails ensure robust mechanical retention on PCB under vibration
- 5 mm mated stack height supports standard 0.100" ribbon-cable and board-to-board connections
What is TST-104-05-L-D used for?
The TST-104-05-L-D is widely used in development boards, evaluation kits, and test fixtures where reliable 0.100" pitch dual-row connectivity is required between PCBs or between a PCB and a ribbon cable. Its shrouded housing makes it a preferred choice for industrial control panels and embedded systems that undergo vibration testing, preventing accidental connector mis-alignment. It also serves as a standard inter-board header in rack-mount instrumentation where 8 signals need to be routed across 2.54 mm-pitched dual-row interfaces.

Frequently Asked Questions
How many positions and rows does the TST-104-05-L-D header provide, and what is the pin pitch?
The TST-104-05-L-D is a dual-row, 4-positions-per-row header totalling 8 positions on a 0.100" (2.54 mm) pitch. This standard pitch is compatible with the vast majority of IDC ribbon cables and mating female receptacles used in embedded development and test environments.
What is the current rating per contact for TST-104-05-L-D and how does it affect wire gauge selection?
SAMTEC TST-series headers are rated at approximately 3 A per contact at room temperature. For a 26 AWG wire this is sufficient for logic-level power and signal lines; heavier 24 AWG wire may be used when routing 2 A to 3 A supply rails through the connector while staying within the thermal derating curve.
When is TST-104-05-L-D preferred over an unshielded single-row header for prototype interconnects?
The shrouded dual-row design of TST-104-05-L-D provides a polarization key that prevents reversed insertion, making it far safer than open-frame single-row strips in rapid-prototyping environments. For 8-wire ribbon-cable assemblies, the dual-row 0.100" format fits standard 16-wire IDC connectors and halves the connector footprint length compared to a single-row 8-pin alternative.
What PCB land pattern does the TST-104-05-L-D require, and how does it fit on a 2-layer board?
The TST-104-05-L-D uses a standard 0.100" × 0.100" through-hole drill grid arranged in 2 rows of 4, requiring 8 plated through-holes of 0.040" (1.0 mm) diameter. This footprint fits easily on any 2-layer or multi-layer PCB and matches land patterns used by most EDA tools' standard connector libraries.
