Applications
The TST-112-01-T-D is commonly used in industrial control panels, test and measurement fixtures, and commercial electronics requiring reliable through-hole board-to-board signal routing. Its standard 0.100 inch pitch and dual-row 24-position layout make it compatible with a wide range of mating female receptacles and IDC cable assemblies. The through-hole termination provides strong mechanical retention in applications subject to vibration or connector mating stress.

Frequently Asked Questions
How many signal positions does TST-112-01-T-D provide, and what is the pin pitch?
The TST-112-01-T-D provides 24 positions in a dual-row through-hole configuration with 0.100 inch (2.54 mm) pitch between contacts, delivering 24 independent signal or power connections in a 1.5 inch body length on a standard PCB grid.
What contact finish does TST-112-01-T-D use, and how does that affect compatibility with gold-plated female connectors?
The TST-112-01-T-D uses matte tin over nickel (50 µin) on mating contacts and tin over nickel barrier on termination. While gold-to-gold contact pairs are preferred for high-cycle applications, tin contacts are suitable for connectors mated fewer than 25 times in typical industrial and test setups.
Is TST-112-01-T-D a lead-free (Pb-free) part, and does it comply with RoHS for export to European markets?
Yes, TST-112-01-T-D is marked Pb-free compliant and meets RoHS requirements, making it eligible for export to European Union markets under current environmental regulations. The tin (Sn) with nickel barrier termination supports lead-free wave or hand soldering processes at temperatures up to 260°C.
What typical PCB design applications benefit from the through-hole dual-row layout of TST-112-01-T-D over surface-mount alternatives?
Through-hole connectors like TST-112-01-T-D with 24 positions are preferred in applications subject to mechanical stress, vibration, or repeated mating cycles, such as industrial control backplanes, test fixture boards, and panel-mount assemblies. The 0.100 inch pitch through-hole pattern provides shear strength exceeding typical SMT pad adhesion in harsh environments.
