What are the key features of SMS-109-02-F-D?
- 18-position dual-row through-hole layout with 0.050 x 0.100 inch pitch enables compact module socket interfaces with reliable mechanical retention
- Through-hole termination provides superior solder joint strength for applications subject to vibration or mechanical stress compared to SMT alternatives
- Micro socket design compatible with 0.050 inch pitch pin headers commonly used in high-density JTAG, SWD, and debug connector standards
- Dual-row configuration maximizes signal density per unit PCB length, reducing connector footprint length by 50 percent versus single-row alternatives
What is SMS-109-02-F-D used for?
The SMS-109-02-F-D is used as a daughter board socket and debug interface connector in embedded computing platforms, FPGA development boards, and industrial control modules. Its 18-position dual-row through-hole configuration suits JTAG and SWD debug port sockets as well as module-to-baseboard interconnects where secure mechanical attachment is required. The mixed 0.050 x 0.100 inch pitch also makes it compatible with legacy and modern pin header standards used in robotics controllers and medical device PCB assemblies.

Frequently Asked Questions
What is the position count and pitch configuration of the SMS-109-02-F-D?
The SMS-109-02-F-D provides 18 positions arranged in 2 rows with a 0.050 inch x 0.100 inch mixed pitch. This dual-row layout accommodates 9 positions per row, and the combined pitch configuration supports mating with fine-pitch micro pin headers used in embedded debug and module interconnect applications where PCB space is constrained.
Why would a designer choose through-hole termination for the SMS-109-02-F-D over a surface mount socket?
Through-hole solder joints for the SMS-109-02-F-D provide mechanical shear strength exceeding 50 N per pin compared to SMT solder joints, making the connector more reliable in applications subject to repeated insertion force, vibration, or thermal cycling between -40°C and +85°C. This is particularly important for module sockets that may be re-mated dozens of times during system development and field maintenance.
Which debug and programming interfaces commonly use the SMS-109-02-F-D dual-row socket?
The 0.050 inch row pitch of the SMS-109-02-F-D matches standard JTAG and ARM SWD debug connector pin-outs used in microcontroller and FPGA development tools. An 18-position dual-row socket at this pitch can accommodate a standard 20-pin JTAG connector with 2 unused positions, enabling direct connection to Arm-standard debug probes providing 3.3 V logic signaling at up to 10 MHz clock rates.
How does the SMS-109-02-F-D dual-row format compare to single-row alternatives in terms of PCB real estate?
The dual-row configuration of the SMS-109-02-F-D packs 18 positions into approximately 9 x 2 contact positions over 0.45 inch x 0.1 inch, which is roughly half the PCB length required by a single-row 18-position socket at the same 0.050 inch pitch. This 50 percent length reduction is critical in compact PCB layouts where edge-area budget is less than 25 mm per connector.
