Key Features
- 4-position dual-row header with 1.27 mm (0.050 inch) pitch providing 4 contact pins in a compact 2.54 mm x 3.43 mm x 7.85 mm SMT footprint
- Gold (10 µin) over nickel (50 µin) mating contact finish on phosphor bronze substrate ensuring low insertion force and long-term contact reliability over 500+ mating cycles
- Tape-and-reel (-TR) packaging supporting automated pick-and-place assembly for high-volume PCB production with consistent orientation
Applications
The FTSH-102-01-L-DH-TR is designed for fine-pitch board-to-board and board-to-cable interconnect applications in aerospace, defense, and compact industrial electronics where high-reliability connections are critical. The 1.27 mm pitch dual-row header is commonly used for JTAG, SWD debug interfaces, and mezzanine board connectors in embedded computing systems with space constraints under 5 mm width. Its gold mating contacts support over 500 mating cycles, making it suitable for test fixtures and field-serviceable modules.

Frequently Asked Questions
What contact finish does FTSH-102-01-L-DH-TR use and how many mating cycles does it support?
The FTSH-102-01-L-DH-TR uses gold (10 µin) over nickel (50 µin) mating contacts on a phosphor bronze substrate. This gold finish provides low and stable contact resistance below 20 mΩ across 500 or more mating cycles, making it reliable for debug headers and field-replaceable module connectors in aerospace and industrial applications.
For which embedded debug or programming interfaces is FTSH-102-01-L-DH-TR particularly suited?
FTSH-102-01-L-DH-TR is ideal for 4-pin JTAG, SWD (Serial Wire Debug), and I2C debug header footprints where 1.27 mm (0.050 inch) pitch minimizes PCB area. Its 4-position dual-row layout provides 4 signal connections sufficient for SWD (SWDIO, SWDCLK, GND, VCC) in microcontroller development boards operating at 1.8 V to 5 V.
How does the 1.27 mm pitch of FTSH-102-01-L-DH-TR reduce PCB footprint compared to 2.54 mm pitch headers?
At 1.27 mm pitch, the FTSH-102-01-L-DH-TR body spans only 2.54 mm across 4 pins, compared to 10.16 mm for a 4-position 2.54 mm pitch header. This 75% reduction in connector width is critical for compact designs such as wearables, medical devices, and miniature industrial controllers where board space under 5 mm x 5 mm is allocated for debug access.
