Frequently Asked Questions
How many positions and rows does the SFM-146-T2-STL-D-A-K-TR connector provide?
The SFM-146-T2-STL-D-A-K-TR provides 92 total contact positions arranged in 2 rows of 46 pins each, with a 0.050-inch (1.27mm) contact pitch. This dual-row configuration maximizes contact density while keeping the connector footprint compact on the PCB, making it suitable for high pin-count FPGA and DSP module interconnects.
What pitch spacing does the SFM-146-T2-STL-D-A-K-TR use and how does this affect PCB routing?
The SFM-146-T2-STL-D-A-K-TR uses a 0.050-inch (1.27mm) pitch, which is half the pitch of standard 0.1-inch (2.54mm) connectors. This tighter pitch requires PCB traces routed at 0.1mm to 0.15mm width between pads, demanding at minimum a 4-layer PCB with 4-mil or finer design rules to successfully escape all 92 signals from the connector footprint.
Is the SFM-146-T2-STL-D-A-K-TR compatible with standard SMT reflow assembly processes?
Yes, the SFM-146-T2-STL-D-A-K-TR is designed for surface-mount termination and is compatible with standard lead-free SAC305 solder paste reflow profiles with peak temperatures of 245°C to 260°C. The tape-and-reel (TR) packaging ensures compatibility with automated pick-and-place machines for medium and high-volume production, with typical placement accuracy requirements of ±0.1mm.
What mating connector family is compatible with the SFM-146-T2-STL-D-A-K-TR socket strip?
The SFM-146-T2-STL-D-A-K-TR is part of Samtec's SFM series socket strip family and mates with corresponding Samtec SFM or TSM series header strips at 0.050-inch pitch with matching 46-position dual-row layouts. Proper mating requires aligning the 92 contacts with the counterpart header, and Samtec specifies a typical mating force of approximately 0.2N per contact, totaling about 18N for all 92 contacts.
