Key Features
- 96-position dual-row format on 0.050" (1.27 mm) pitch concentrates 96 signal or power contacts in a compact SMT footprint for dense FPGA and SoC interfaces
- T2 tail variant provides a shorter solder tail optimized for tight back-side PCB clearance on ultra-slim board stacks
- F low-profile stack height minimizes board-to-board separation, enabling compact module socket designs where vertical space is constrained to under 5 mm
Applications
The SFM-148-T2-F-D-A is designed for high-density FPGA mezzanine sockets, SoC module interfaces, and compact embedded computing daughter-card connectors requiring 96 signal channels in a minimal PCB area. Its low-profile F height and T2 tail make it suitable for slim embedded systems, wearable computing boards, and high-channel-count test fixtures where board separation must remain below 5 mm.

Frequently Asked Questions
How does the F low-profile stack height of the SFM-148-T2-F-D-A compare to the standard H height variant in board-to-board clearance?
The F (flush or low-profile) height option on the SFM-148-T2-F-D-A reduces the above-board mating engagement height to approximately 1.0 mm to 2.0 mm compared to 4.0 mm or more for the H (high) variant. This reduced clearance is essential in 96-contact mezzanine applications where total board stack height must remain under 5 mm, such as slim wearable or handheld device motherboard-to-module interfaces.
What current capacity can the SFM-148-T2-F-D-A carry per contact, and how should power pins be allocated across 96 positions?
SAMTEC SFM series contacts are rated at 1 A per contact under standard conditions at 25°C. For the 96-position SFM-148-T2-F-D-A, designers can allocate up to 16 positions as dedicated power pins delivering 16 A total while reserving the remaining 80 contacts for logic-level signal routing. Grouping power contacts at the ends of the dual-row connector reduces crosstalk between high-current and sensitive signal lines.
For a compact 96-channel FPGA expansion socket, how does the SFM-148-T2-F-D-A reduce board area compared to a 2.54 mm pitch alternative?
Routing 96 contacts on a 0.050" (1.27 mm) pitch dual-row connector requires approximately 62 mm of connector length on the SFM-148-T2-F-D-A, versus 125 mm for a 2.54 mm pitch equivalent. This 50% length reduction on a 2-row, 96-contact interface saves roughly 800 mm² of PCB real estate, freeing space for additional circuitry in constrained FPGA mezzanine and SoC module designs.
