Key Features
- Ultra-compact body measuring 0.135" x 0.155" with 4-position dual-row 0.050" (1.27 mm) pitch layout enables debug and programming headers on the smallest PCB footprints
- Gold (10 µin) over nickel (50 µin) mating contact finish provides low contact resistance below 20 mΩ and reliable signal integrity across 100+ mating cycles
- RoHS-compliant construction with matte tin termination ensures lead-free assembly compatibility and suitability for commercial, industrial, and medical electronics
Applications
The FTSH-102-01-L-DV is widely used as a JTAG, SWD, or serial programming debug header on ARM Cortex microcontroller boards, FPGA evaluation modules, and compact embedded systems where a 4-pin 1.27 mm pitch interface saves critical PCB area. Its gold-contact finish and dual-row layout make it suitable for production test fixtures requiring repeatable low-resistance contact over many insertion cycles. Engineers also use this connector in IoT sensor nodes and wearable devices where the sub-4 mm body size allows debug access without sacrificing board space.

Frequently Asked Questions
What is the pin count, pitch, and body size of the FTSH-102-01-L-DV?
The FTSH-102-01-L-DV has 4 total positions in a dual-row 2x2 configuration at 0.050" (1.27 mm) pitch. The connector body measures 0.135" length by 0.155" depth by 0.1" breadth, making it one of the most compact debug headers available for 1.27 mm pitch board-to-board or programming cable applications.
What contact finish does the FTSH-102-01-L-DV use and how does it affect reliability in debug applications?
The FTSH-102-01-L-DV uses 10 µin gold over 50 µin nickel on the mating contacts. This gold-over-nickel finish maintains contact resistance below 20 mΩ even after 100 or more mating cycles from programming cables or test fixtures, ensuring reliable JTAG clock and data signal integrity for ARM Cortex-M and RISC-V debug sessions at up to 10 MHz SWD clock rates.
For which debug interface standards is the FTSH-102-01-L-DV a suitable header choice?
The FTSH-102-01-L-DV 4-position dual-row header at 1.27 mm pitch is compatible with Cortex Debug Connector (2x5, but often reduced to 2x2 for minimal interfaces), SWD 2-wire debug with reset, and custom vendor-specific UART boot interfaces. Many STM32, Nordic nRF52, and NXP Kinetis boards use a 4-pin 1.27 mm header for SWD clock, SWD data, power, and ground connections.
How does the lead time for FTSH-102-01-L-DV compare to similar SAMTEC debug connectors?
The FTSH-102-01-L-DV has a factory lead time of just 1 week, significantly shorter than the 8 to 15 weeks typical for many specialty connectors. This short lead time, combined with RoHS-compliant construction and gold mating contacts, makes it a low-risk choice for production schedules that cannot accommodate long supply chain delays for a 4-position debug header.
