What are the key features of SFM-103-L2-SM-D-A-P?
- Compact 6-position dual-row (2×3) layout at 1.27 mm (0.050") pitch delivers high-density board-to-board connectivity in minimal PCB footprint
- High-reliability gold-plated contacts rated 1.5 A per pin ensure stable low-resistance mating for both signal and low-power supply lines
- Surface-mount termination (SM) with gold-plated tails enables standard SAC305 reflow assembly and precise automated placement
What is SFM-103-L2-SM-D-A-P used for?
The SFM-103-L2-SM-D-A-P is ideal for compact daughter cards, sensor modules, and embedded peripheral boards that need a small 6-pin dual-row 1.27 mm pitch socket for reliable repeated connection to a host PCB. Its miniature footprint suits wearable electronics, medical diagnostic modules, and camera interface boards where board area is severely limited. The high-reliability gold contacts support frequent mating and de-mating cycles required in field-replaceable module systems.

Frequently Asked Questions
How many contacts does the SFM-103-L2-SM-D-A-P provide and how are they arranged on the PCB footprint?
The SFM-103-L2-SM-D-A-P provides 6 total contacts in a 2-row by 3-position arrangement on a 1.27 mm (0.050") pitch. The compact footprint measures approximately 3 × 1.27 mm = 3.81 mm in length and 2.54 mm in width between row centerlines, making it one of the smallest dual-row SFM configurations suitable for micro-module board-to-board connections where every square millimeter of PCB area is at a premium.
What current rating does each contact in the SFM-103-L2-SM-D-A-P support, and can some pins carry a 3.3 V supply rail?
Each contact is rated for 1.5 A continuous current with gold plating providing contact resistance below 30 mΩ. For a 3.3 V supply rail, a single pin can deliver up to 1.5 A, which covers typical low-power sensor or microcontroller loads. If the module draws up to 3 A at 3.3 V, two of the 6 pins can be paralleled for the supply, leaving the remaining 4 pins for I2C, SPI, or GPIO signals.
Which mating pin strip from Samtec is the correct counterpart for the SFM-103-L2-SM-D-A-P?
The SFM-103-L2-SM-D-A-P socket mates with Samtec TSM-103 dual-row pin strips or SFM-103 pin-side variants at the matching 1.27 mm pitch and 2×3 count. The L2 suffix in the socket part number specifies a 2.41 mm (0.095") above-board insulator height, so the selected mating pin strip must have a pin length that accommodates this stack height without bottoming out before full mating engagement.
For a camera interface module requiring SPI and I2C on a shared connector, how suitable is the SFM-103-L2-SM-D-A-P?
The SFM-103-L2-SM-D-A-P provides 6 positions that can simultaneously carry a 4-wire SPI bus (SCK, MOSI, MISO, CS) plus an I2C bus (SDA, SCL), or alternatively a 4-pin MIPI-compatible control sideband plus 2 power pins in a single 6-pin connector. Its 1.27 mm fine pitch keeps the connector footprint under 25 mm² on the camera module PCB, which is critical for miniature OV5640 or Sony IMX sensor boards where camera lens modules already claim most of the available area.
How does the SFM-103-L2-SM-D-A-P support high-volume automated assembly and what reflow profile is compatible?
The -SM suffix and surface-mount solder tails make the SFM-103-L2-SM-D-A-P fully compatible with standard lead-free SAC305 reflow profiles peaking at 260°C per IPC/JEDEC J-STD-020. Without a -TR tape-and-reel suffix, units are delivered in trays or tubes, but the SMT termination style still allows pick-and-place placement at throughputs exceeding 5000 placements per hour on typical SMT lines. The A suffix indicates a gold-plated contact finish verified for at least 50 mate and de-mate cycles.
