What are the key features of SFM-149-T2-ZZ-D-A-K-TR?
- 98 pins in a dual-row 1.27 mm pitch SMT socket strip, delivering high pin density in a compact footprint for dense PCB interconnects
- High-reliability socket construction rated for multiple mating cycles at 0.050 inch pitch, suitable for test, measurement, and production board applications
- Tape-and-reel (TR) packaging on 8 mm carrier tape for automated pick-and-place assembly in high-volume production environments
What is SFM-149-T2-ZZ-D-A-K-TR used for?
The SFM-149-T2-ZZ-D-A-K-TR is used in high-density board-to-board interconnects for FPGA daughter cards, memory modules, and communication backplane assemblies where 98 signals must route between boards in a minimal PCB area. Its 1.27 mm pitch provides approximately twice the pin density of a 2.54 mm pitch connector, enabling compact stackable module designs for embedded computing and telecom line cards. The high-reliability socket contacts also suit removable evaluation boards and hardware debug interfaces where repeated mating cycles are expected.

Frequently Asked Questions
How many positions and what pin pitch does the SFM-149-T2-ZZ-D-A-K-TR provide?
The SFM-149-T2-ZZ-D-A-K-TR provides 98 positions in a dual-row arrangement with 1.27 mm (0.050 inch) pin pitch. This 98-pin count can simultaneously carry 32 data lines, 10 address lines, and multiple power and ground pins, making it practical for parallel bus interfaces in embedded processor and FPGA board stacks.
What mating connector family is compatible with SFM-149-T2-ZZ-D-A-K-TR?
The SFM series mates with Samtec TSM or SHF dual-row header connectors at 1.27 mm pitch. Verify that the mating header has 49 pins per row (98 total) and the same 0.050 inch pitch to ensure full 98-position engagement. Mated stack height depends on the selected header tail length, typically ranging from 3 mm to 11 mm above the PCB surface.
Can SFM-149-T2-ZZ-D-A-K-TR be reflowed in a standard SMT oven, and what temperature does it tolerate?
Yes, the SMT body of SFM-149-T2-ZZ-D-A-K-TR is designed for standard lead-free reflow processing with peak temperatures up to 260°C per IPC/JEDEC J-STD-020. The TR suffix confirms tape-and-reel packaging for pick-and-place automation, allowing high-throughput SMT assembly of this 98-position socket without manual placement steps.
How does 1.27 mm pitch on SFM-149-T2-ZZ-D-A-K-TR compare to 2.54 mm pitch connectors in high-density designs?
At 1.27 mm pitch, the SFM-149-T2-ZZ-D-A-K-TR occupies roughly half the PCB length of an equivalent 2.54 mm pitch 98-pin connector — approximately 31 mm versus 62 mm for a dual-row strip. This space saving is critical in blade servers, network switches, and compact embedded modules where multiple high-pin-count connectors must fit within a few square centimeters of board area.
