Frequently Asked Questions
What contact finish is used on the SFM-105-02-L-D and how does it affect contact reliability?
The SFM-105-02-L-D uses 10 µin (0.25 µm) gold over 50 µin (1.27 µm) nickel on its mating contacts, providing a hard-wearing corrosion-resistant interface that maintains contact resistance below 20 mΩ across 500 or more mating cycles. The nickel underplate acts as a diffusion barrier that prevents gold migration, extending connector service life in high-cycle applications.
How does the E.L.P. feature on the SFM-105-02-L-D benefit board-stacking mezzanine designs?
The E.L.P. (Extended Lengths of Pin) feature provides longer pin tails on the SFM-105-02-L-D that accommodate varying board-to-board stack heights from approximately 4 mm to 12 mm. This flexibility allows engineers to use the same connector across multiple mezzanine designs with different PCB spacing requirements, reducing the number of distinct part numbers needed in the BOM.
What are the physical dimensions of the SFM-105-02-L-D housing?
The SFM-105-02-L-D has a body length of 0.265 inch (6.73 mm), body depth of 0.185 inch (4.70 mm), and body breadth of 0.095 inch (2.41 mm). These compact dimensions allow the 10-position dual-row socket to be placed in tight PCB areas, and the 1.27 mm (0.050 inch) pitch matches standard SAMTEC mating header series without requiring custom footprints.
What lead time should I expect when ordering the SFM-105-02-L-D for a production build?
SAMTEC lists the SFM-105-02-L-D with a factory lead time of approximately 1 week, making it readily available for both prototype quantities and production orders. The Pb-free, RoHS-compliant construction ensures the part can be sourced without additional compliance screening, which simplifies procurement for EU and Asian markets requiring lead-free certification.
