Key Features
- 10-position dual-row layout on 0.100 inch (2.54 mm) pitch for compact high-density interconnection
- Gold (10 μin) over Nickel (50 μin) contact mating finish for low contact resistance and extended cycle life
- Through-hole termination with tin-over-nickel solder finish for strong PCB mechanical retention
- RoHS-compliant construction meets global environmental regulations
- Integrated polarizing shroud with 0.365 x 0.365 x 0.8 inch body prevents mismating and protects pins
Applications
The TST-105-02-L-D is suitable for board-to-board and board-to-cable signal connections in embedded computing modules, industrial I/O expansion boards, and test and measurement equipment where a 10-position 0.100 inch pitch interface is required. Its gold-plated contacts make it particularly well-suited for low-level signal applications such as sensor interfaces, data acquisition systems, and communication module connections where contact resistance stability is critical. The shrouded design is frequently used in robotics platforms, motor control systems, and laboratory instruments requiring secure, polarized interconnections.

Frequently Asked Questions
What contact finish does TST-105-02-L-D use and why does it matter for signal integrity?
TST-105-02-L-D uses a gold (10 microinch) over nickel (50 microinch) contact mating finish, which delivers low and stable contact resistance across thousands of mating cycles, making it ideal for sensitive signal applications where oxide buildup on tin contacts could cause intermittent connections.
How many positions and rows does TST-105-02-L-D provide, and what pitch spacing applies?
The TST-105-02-L-D provides 10 total positions arranged in a dual-row configuration with 5 contacts per row on a standard 0.100 inch (2.54 mm) pitch, which is compatible with a wide range of off-the-shelf mating receptacles, IDC cable connectors, and ribbon cable assemblies.
How does TST-105-02-L-D compare to a non-shrouded header in applications with repeated cable insertions?
The polarizing shroud of TST-105-02-L-D physically guides the mating receptacle into the correct orientation, preventing pin damage and reverse-polarity connections. In high-cycle applications such as test fixtures or field-serviceable equipment, this reduces maintenance costs compared to unshrouded 0.100 inch headers where pin bending is common.
What is the factory lead time for TST-105-02-L-D and is it RoHS compliant?
TST-105-02-L-D has a factory lead time of approximately 1 week and is fully RoHS and REACH compliant, making it eligible for use in products sold in EU and other regulated markets without additional environmental certification steps.
