Frequently Asked Questions
What is the pin count and row arrangement of the TSM-109-03-SS-DH-A-K-TR?
The TSM-109-03-SS-DH-A-K-TR provides 18 total contact positions in a dual-row layout, with 9 positions per row at a 2.54 mm (0.100 inch) pitch. This compact arrangement supports up to 9 differential pairs or 18 single-ended signal lines in surface mount applications.
For which embedded computing module designs is the TSM-109-03-SS-DH-A-K-TR a good fit?
Small form-factor embedded modules such as Arduino shields, Raspberry Pi HATs, and custom sensor boards with 18-signal I/O buses frequently use connectors of this type. The 2.54 mm pitch aligns with standard 0.1-inch header footprints, simplifying PCB layout and mating connector selection.
How does gold plating on the TSM-109-03-SS-DH-A-K-TR contacts improve reliability?
Gold plating (K option) provides a contact resistance below 20 milliohms and prevents oxidation that can degrade signal integrity over time. Gold-plated contacts are preferred for applications requiring thousands of mating cycles or operation in humid and corrosive environments at temperatures up to 85°C.
Is the TSM-109-03-SS-DH-A-K-TR interchangeable with TSM-109-01 or TSM-109-02 variants?
The TSM-109 series shares the same 18-position 2.54 mm dual-row footprint across variants; the -03 suffix denotes the solder tail column spacing variant. Different tail options (SS, TM, TL) may have slightly different PCB land patterns, so verifying the specific footprint against the datasheet is recommended before substituting between variants.
