What are the key features of SFM-105-L2-F-D-A-P?
- 10 positions (5 per row) in ultra-compact dual-row 0.050 inch pitch layout for minimal-footprint signal interfaces
- A (polarizing) key ensuring correct mating orientation to protect 10-pin signal connections
- P (press-fit board lock) retention posts preventing connector shift during reflow soldering at up to 260 °C
- F contact style with gold-over-nickel plating providing low contact resistance below 20 milliohms for reliable signal paths
What is SFM-105-L2-F-D-A-P used for?
The SFM-105-L2-F-D-A-P is used in ultra-compact embedded modules, small sensor boards, and wearable electronics requiring 10 dual-row contacts at 1.27 mm pitch in the smallest possible SMT connector footprint. Its polarization and board-lock features are valuable for field-replaceable micro-module applications where reliable solder alignment and mis-insertion protection are required within a 5 x 2 pin configuration.

Frequently Asked Questions
How compact is the SFM-105-L2-F-D-A-P footprint, and what is its pin count configuration?
The SFM-105-L2-F-D-A-P provides 10 contacts in a 5 x 2 dual-row layout at 0.050 inch (1.27 mm) pitch, making it one of the smallest SAMTEC SFM series connectors. The 5-contact row spans approximately 6.35 mm in length, and the dual-row 2.54 mm width creates a PCB footprint of about 6 mm x 5 mm total, fitting on sensor interface boards, micro-controller modules, and wearable devices with very limited board area.
What are the benefits of combining the A polarizing and P board-lock features on a 10-pin connector like SFM-105-L2-F-D-A-P?
On a small 10-pin connector, the A polarizing key prevents 180-degree mis-insertion that would reverse 10 signal and power lines on a 3.3 V or 5 V board, potentially damaging sensitive ICs. The P board-lock press-fit posts anchor the connector to PCB holes before soldering, preventing the lightweight 10-pin body from shifting on paste-printed pads during reflow at 260 °C peak, improving solder joint quality and manufacturing yield on dense micro-module assemblies.
When would a designer select SFM-105-L2-F-D-A-P over a larger 20-pin or 40-pin SAMTEC SFM socket for a module interface?
A designer selects the 10-pin SFM-105-L2-F-D-A-P when the inter-board interface requires only 5 signals per side in a 2-row arrangement, minimizing the connector to a 6 mm x 5 mm SMT footprint versus 12 mm or 25 mm for 20-pin or 40-pin SFM variants. This is common in IMU sensor modules, GPS daughter cards, and wireless radio modules communicating over SPI (4 wires), UART (2 wires), or I2C (2 wires) plus power, where 10 pins is sufficient and board area is at a premium.
Is SFM-105-L2-F-D-A-P suitable for high-speed digital signals, and what is its rated frequency performance?
The SFM-105-L2-F-D-A-P at 0.050 inch (1.27 mm) pitch is suitable for moderate-speed digital signals up to approximately 1 GHz with careful PCB design, consistent with SAMTEC SFM series specifications for signal integrity at this pitch. For applications below 100 MHz such as SPI, I2C, LVDS pairs, and UART on 3.3 V rails, all 10 contacts perform reliably. Above 1 GHz, engineers should evaluate controlled-impedance routing and consult SAMTEC's signal integrity data for the specific L2 stack height variant.
