What is HTSW-103-07-T-S used for?
The HTSW-103-07-T-S is used in development boards, embedded module interfaces, and compact sensor assemblies where a 3-pin right-angle or vertical 0.100 inch header provides straightforward signal or power connections. Its small form factor fits tightly spaced board layouts in handheld devices, IoT nodes, and industrial sensor hubs requiring reliable board-to-wire connectivity with standard mating socket housings. Engineers favor this part for prototyping and low-to-mid volume production runs due to its broad mating compatibility and short lead times.

Frequently Asked Questions
What is the contact pitch and row count of HTSW-103-07-T-S, and how many positions does it provide?
The HTSW-103-07-T-S is a 3-position, single-row vertical header with 0.100 inch (2.54 mm) contact pitch. This compact configuration supports 3 independent signal or power connections, making it suitable for UART, I2C, SPI, and low-current power interfaces in embedded systems where board space is limited to a 0.3 inch row length.
Which embedded or IoT design scenarios benefit most from integrating the HTSW-103-07-T-S header?
IoT sensor nodes, UART debug ports, I2C peripheral headers, and low-power module connectors all benefit from the HTSW-103-07-T-S. The 3-pin, 2.54 mm pitch format is compatible with a wide range of standard 0.100 inch crimp housings and ribbon cables rated to 3 A per contact, covering most digital signal and auxiliary power needs in compact embedded board designs rated from -55°C to 125°C.
How does the matte tin over nickel contact finish of HTSW-103-07-T-S affect connector durability and mating compatibility?
The matte tin over nickel finish on HTSW-103-07-T-S provides a contact resistance below 20 milliohms at initial mating, maintaining reliable signal integrity across typical 30-plus mating cycles in lab and field environments. The nickel barrier layer beneath the tin prevents tin diffusion into the copper contact base, extending service life compared to tin-only finishes used in lower-cost headers at the same 2.54 mm pitch.
When is HTSW-103-07-T-S a practical alternative to a surface-mount 3-pin connector in a high-vibration application?
Through-hole mounting in HTSW-103-07-T-S anchors each of the 3 contacts in plated PCB vias, providing pull-out forces several times greater than surface-mount pads under vibration or cable strain. For industrial sensors, motor controllers, or outdoor IoT enclosures subject to continuous vibration at frequencies from 10 Hz to 500 Hz, through-hole headers maintain reliable electrical contact where SMD alternatives risk solder joint fatigue and intermittent opens.
