Key Features
- 26-position dual-row shrouded header at 0.100 inch pitch with keyed shroud for polarized, error-proof mating in board-to-board applications
- Gold (30 µin) over Nickel (50 µin) mating contact finish delivers low contact resistance and high durability for repeated mating cycles
- 1.6 inch body with 0.365 inch depth provides robust mechanical support on the PCB for high-vibration industrial and military environments
Applications
The TST-113-03-S-D is well suited for shrouded board-to-board and board-to-cable interconnects in industrial automation, defense electronics, and test and measurement instruments where polarized mating with 26 positions at 0.100 inch pitch is required. Its gold-over-nickel contact finish supports applications demanding low contact resistance and high mating cycle durability, such as modular embedded computing backplanes. The shrouded housing prevents misalignment during repeated plug/unplug operations in field-serviceable equipment.

Frequently Asked Questions
What contact finish does the TST-113-03-S-D use on its mating pins and why does it matter?
The mating contacts are finished with 30 µin Gold over 50 µin Nickel, which provides excellent corrosion resistance and low contact resistance across all 26 positions. This gold plating is ideal for applications requiring more than 100 mating cycles or operating in humid or harsh environments, such as modular industrial instrumentation and defense electronics.
What are the body dimensions of the TST-113-03-S-D and how do they affect PCB layout?
The TST-113-03-S-D body measures 1.6 inch in length, 0.365 inch in depth, and 0.365 inch in breadth. These dimensions define the PCB footprint clearance needed around the 26-position dual-row header. Designers should reserve a 1.6 × 0.365 inch area and account for a 0.365 inch component height when planning keep-out zones for adjacent components.
For which types of systems is the shrouded design of the TST-113-03-S-D particularly beneficial?
The shrouded housing of the TST-113-03-S-D provides mechanical keying that prevents reversed or offset mating, making it ideal for field-serviceable modular systems such as industrial controllers, embedded computing boards, and medical instruments where technicians may connect cables under limited visibility. With 26 positions at 0.100 inch pitch, it supports broad signal buses while the shroud ensures correct orientation every time.
How long is the factory lead time for TST-113-03-S-D and what should procurement teams plan for?
The factory lead time for TST-113-03-S-D is 10 weeks, which is longer than many standard connectors. Procurement teams working on production schedules should place orders at least 10 to 12 weeks before their board assembly start date and consider stocking buffer quantities if the 26-position shrouded header is on a critical path for system builds.
