What are the key features of TST-102-05-G-D?
- 4-position dual-row shrouded header on 2.54 mm (0.100-inch) pitch with polarization key preventing reverse mating in ribbon cable and IDC connector assemblies
- Gold-plated through-hole pins with 0.025-inch square post design rated for 1 A per contact and low contact resistance below 20 milliohms
- Shrouded housing provides mechanical protection for pins and aligns mating connectors, reducing field wiring errors in industrial and embedded systems
What is TST-102-05-G-D used for?
The TST-102-05-G-D is commonly used in embedded systems, industrial control panels, and prototyping boards where a compact 4-pin shrouded header is needed to connect ribbon cables or wire harnesses carrying power and signal lines at 2.54 mm pitch. Its polarized shroud prevents incorrect mating, which is critical in safety-sensitive applications such as motor drives and sensor modules. The through-hole mounting style also provides robust mechanical retention suitable for environments with vibration or frequent connector mating.

Frequently Asked Questions
What is the pitch, contact count, and current rating of the TST-102-05-G-D shrouded PCB header?
The TST-102-05-G-D features 4 positions in a dual-row layout on a 2.54 mm (0.100-inch) pitch, with each gold-plated through-hole pin rated for 1 A continuous current. Contact resistance is specified below 20 milliohms, making it appropriate for low-power signal and auxiliary power connections in embedded control boards and sensor interfaces.
What connector types mate with the TST-102-05-G-D, and how does the shroud help in field assembly?
The TST-102-05-G-D mates with standard 4-pin IDC ribbon cable connectors and crimp-style female housings on a 2.54 mm pitch, including common 0.100-inch discrete wire connectors. The molded shroud aligns the mating connector during insertion and includes a polarization feature that physically prevents 180-degree reversed mating, reducing wiring errors during field installation and maintenance.
Is the TST-102-05-G-D suitable for through-hole wave soldering, and what PCB land pattern does it require?
Yes, the TST-102-05-G-D is a through-hole component compatible with both wave soldering and hand soldering processes. The standard 2.54 mm pitch dual-row pattern requires 0.8 mm to 1.0 mm drilled holes on a 2.54 mm grid, which matches the most common PCB land pattern used for 0.025-inch square-post headers and is supported by virtually all PCB design software libraries.
When should the TST-102-05-G-D be preferred over an unshielded open-pin header for a 4-wire connection?
The shrouded TST-102-05-G-D is preferred when the 4-pin connector will be mated and unmated in the field or during production testing, since the housing physically guides the mating connector onto the 2.54 mm pitch pins and prevents single-pin misalignment that can cause shorts. For fully enclosed PCB-internal connections that are never disconnected after assembly, an unshielded 4-pin header may suffice at lower cost.
