Frequently Asked Questions
How many contacts does SFM-122-L2-SM-D-A-P-TR provide per row and what is the overall connector length?
The SFM-122-L2-SM-D-A-P-TR has 44 total positions with 22 contacts per row at 0.050 inch (1.27 mm) pitch, resulting in an overall connector length of approximately 28 mm. This makes it a mid-range option within the SFM family, balancing signal count with physical size for mezzanine applications.
For an IoT gateway module requiring 44 signals between a base board and a radio expansion card, how does SFM-122-L2-SM-D-A-P-TR fit this need?
The SFM-122-L2-SM-D-A-P-TR provides exactly 44 positions at 1.27 mm pitch, accommodating typical IoT expansion interfaces including SPI, I2C, UART, GPIO, and power rails in a single connector pair. The tape-and-reel packaging supports the automated assembly lines used in cost-sensitive consumer IoT products, and the surface-mount profile keeps overall module height within 10 mm stack constraints.
How does the L2 designation in SFM-122-L2-SM-D-A-P-TR differentiate this part from the base SFM-122 model?
The L2 suffix in SAMTEC SFM part numbers indicates a specific lead length or lead style variant, providing a longer lead or leg configuration than the standard L1 version. This affects the connector's standoff height above the PCB surface and the solder joint geometry, giving designers flexibility to match the required board separation distance in their mezzanine stack, typically ranging from 4 mm to over 15 mm.
What reel quantity is standard for SFM-122-L2-SM-D-A-P-TR and when should engineers order tray or strip alternatives?
The TR suffix on SFM-122-L2-SM-D-A-P-TR indicates tape-and-reel packaging in standard 1,000-piece reels, optimized for automated pick-and-place machines. Engineers running prototype or NPI builds at fewer than 100 pieces should order the non-TR variant in tray or cut-strip form to avoid paying for a full reel, while production volumes above 500 pieces per week benefit from the TR format's continuous feed.
