What are the key features of SFM-147-T2-SM-D-LC?
- 94-position dual-row socket at 0.050" (1.27 mm) pitch, enabling very high pin-count board-to-board connections in a compact SMT footprint
- High-reliability contact system rated for a minimum of 100 mating cycles, suitable for telecom blades and modular computing systems
- Surface mount termination with SMT lead style compatible with standard reflow soldering at peak 260°C profiles
What is SFM-147-T2-SM-D-LC used for?
The SFM-147-T2-SM-D-LC is designed for very high pin-count mezzanine and board-to-board interconnections in advanced telecom line cards, FPGA daughter boards, and high-performance embedded computing platforms where 94 signals must be reliably routed between PCBs. Its 0.050" pitch dual-row format delivers extreme signal density, reducing the number of connectors needed on congested backplanes. The SMT construction integrates seamlessly into automated PCB assembly workflows, lowering production time for complex multi-board systems.

Frequently Asked Questions
What is the total position count and pitch of the SFM-147-T2-SM-D-LC, and why does that matter for high-speed designs?
The SFM-147-T2-SM-D-LC provides 94 positions in a dual-row format at 0.050" (1.27 mm) pitch. At this density, a single connector can carry a 64-bit data bus with power, ground, and control signals, reducing the PCB area consumed by interconnects and minimizing stub lengths that degrade signal integrity above 500 MHz.
How does the 94-position SMT SFM-147 compare to two 47-position connectors for the same interface?
Using a single SFM-147-T2-SM-D-LC with 94 positions instead of two 47-position connectors eliminates a mechanical gap in the connector array, reduces the number of PCB land patterns to manage, and simplifies mechanical alignment. For backplane designs routing more than 80 signals, a single 94-position connector also shortens total trace length by consolidating all nets to one assembly point.
Is SFM-147-T2-SM-D-LC suitable for FPGA daughter card interfaces with parallel memory buses?
Yes. FPGA designs using 32-bit or 64-bit DDR memory buses along with address, control, power, and ground signals can exceed 80 pins, fitting well within the 94-position capacity of SFM-147-T2-SM-D-LC. At 0.050" pitch, the connector stays within a compact board edge zone, leaving interior board space for BGA routing in fine-pitch FPGA packages.
What reflow temperature profile is compatible with mounting SFM-147-T2-SM-D-LC?
The SFM-147-T2-SM-D-LC uses SMT termination compatible with standard lead-free reflow profiles peaking at approximately 260°C, per IPC-J-STD-020 classification for SMT connectors. Designers should confirm with SAMTEC's datasheet that the connector body and contact materials withstand the chosen ramp rate and dwell time to avoid warpage on the 94-position strip during soldering.
