TST-103-04-G-D SAMTEC Connector (Other) In Stock
The SAMTEC TST-103-04-G-D is a 6-position, dual-row shrouded PCB header on 0.100 inch (2.54 mm) pitch, designed for secure board-to-cable mating. The shroud prevents mismating while the dual-row layout delivers 6 contacts in a compact through-hole footprint suitable for a wide range of PCB applications.

What are the key features of TST-103-04-G-D?
- 6-position dual-row layout on 0.100" (2.54 mm) pitch for compact through-hole mounting
- Shrouded housing prevents 180-degree mismating, protecting circuits during cable insertion
- Gold-plated (G) contact finish provides low-contact-resistance and reliable signal integrity
- Dual-row (D) configuration maximizes contact density within a minimal PCB footprint
- Compatible with SAMTEC TSW and FFSD cable assemblies for versatile board-to-cable interconnects
What is TST-103-04-G-D used for?
The TST-103-04-G-D is commonly used in embedded systems, development boards, and industrial control modules where a compact 6-pin shrouded header is needed for ribbon-cable or wire-harness connections. Its gold-plated contacts and mismating-prevention shroud make it a reliable choice for signal and low-power connections on PCBs used in test equipment, robotics, and IoT gateway hardware.

Frequently Asked Questions
What contact finish does the TST-103-04-G-D use, and how does that affect long-term reliability in signal applications?
The TST-103-04-G-D uses gold (G) plating on its 6 contacts, which provides a contact resistance typically below 20 milliohms and excellent corrosion resistance over thousands of mating cycles. Gold plating is preferred for low-level signal applications where oxide build-up on tin contacts could introduce noise or intermittent connections.
How many total pins does the TST-103-04-G-D have, and how are they arranged on the PCB?
The connector has 6 total positions arranged in 2 rows of 3 pins each, on a 0.100 inch (2.54 mm) pitch both along and across the rows. This dual-row through-hole pattern allows secure soldering into standard 0.100-inch grid PCB layouts commonly found in development boards and industrial controllers.
Which SAMTEC cable assemblies are compatible with the TST-103-04-G-D for a complete board-to-cable interconnect solution?
The TST-103-04-G-D mates with SAMTEC TSW and FFSD series flat flexible cable assemblies. These cable mates are available in ribbon-cable lengths from 50 mm to 300 mm, terminating in a matching 6-position dual-row housing that clicks into the shrouded header to form a keyed, pull-rated connection.
For a motor-control PCB that already uses 0.100-inch pin headers, does the TST-103-04-G-D offer any procurement advantage over a non-shrouded header?
Yes. The shrouded TST-103-04-G-D replaces a non-shrouded header without changing the 0.100-inch (2.54 mm) footprint, so no PCB redesign is needed. In a motor-control environment where vibration or a technician working near 48 V bus bars could accidentally invert a 6-pin ribbon cable, the shroud eliminates that reversal risk at essentially no added board space cost.
