What are the key features of TST-104-04-F-D?
- 8-position dual-row through-hole header on 2.54 mm (0.100") pitch for compact board-to-cable interconnects
- Female socket contacts rated at 3 A per pin for reliable signal and low-power supply connections
- Polarized shroud prevents reversed or offset mating, reducing field assembly errors in high-volume production
- Through-hole mounting provides robust mechanical retention and withstands wave-soldering temperatures up to 260°C
What is TST-104-04-F-D used for?
TST-104-04-F-D is used in embedded systems, industrial control boards, and development platforms where a reliable 8-pin dual-row through-hole socket is needed for attaching ribbon cables or discrete wire harnesses on a 2.54 mm grid. Its polarized shroud ensures correct orientation when connecting I/O expansion modules, sensor arrays, or power distribution cables in field-serviceable equipment. The through-hole format provides superior PCB pull-out strength versus SMT alternatives in applications subject to mechanical vibration or repeated cable plug-unplug cycles.

Frequently Asked Questions
How many positions and rows does the TST-104-04-F-D have, and what is its contact pitch?
TST-104-04-F-D is an 8-position dual-row (4 contacts per row) through-hole socket on a 2.54 mm (0.100 inch) pitch. This standard footprint mates directly with 2.54 mm male pin headers and IDC ribbon cable connectors without adapter boards, covering the most common board-to-cable interconnect standard in embedded systems design.
What current rating per pin should designers rely on when routing power through TST-104-04-F-D?
Each contact in TST-104-04-F-D is rated at 3 A, allowing the 8-pin connector to carry up to 24 A total if all pins are used for power, or a mix of signal lines at under 1 A each alongside a 3 A power pair. For sustained 3 A operation on a single pin, a 26 AWG minimum wire gauge is recommended to keep resistive heating below 30°C rise at 25°C ambient.
Why choose the through-hole TST-104-04-F-D over an equivalent SMT socket for a panel-mount control board?
Through-hole solder joints on TST-104-04-F-D withstand pull-out forces exceeding 30 N per pin, compared to 8–10 N for reflow-soldered SMT pads of the same pitch. This mechanical advantage matters in panel-mount control boards where cables are repeatedly connected and disconnected during maintenance, reducing the risk of pad delamination after 50 or more insertion cycles.
Which cable assembly types mate directly with TST-104-04-F-D for a quick prototype interconnect?
TST-104-04-F-D mates with any standard 2.54 mm dual-row IDC ribbon cable assembly (such as SAMTEC FFSD or compatible 2x4 IDC housings) or discrete-wire connectors using 22–28 AWG crimped contacts on a 2.54 mm housing. Ribbon cables with 8 conductors on 0.050 inch pitch can be IDC-crimped to a 2x4 dual-row plug in under 5 minutes without specialized tooling.
