Key Features
- 8-position dual-row 1.27 mm pitch high-reliability SMT socket for dense board-to-board connections
- T2 tail length option provides optimized solder standoff for consistent SMT reflow joint quality
- Dual-row configuration doubles contact density versus single-row headers in the same 1.27 mm pitch footprint
Applications
SFM-104-T2-SM-D-A provides compact 8-pin dual-row socket connectivity for high-density board-to-board links in communications, computing, and test equipment. At 1.27 mm pitch it is widely used in FPGA daughter cards, memory modules, and measurement instrumentation requiring reliable SMT mating with minimal PCB footprint. Its high-reliability socket contact design supports applications demanding consistent electrical performance across repeated mating cycles.

Frequently Asked Questions
How does the 1.27 mm pitch of SFM-104-T2-SM-D-A improve board-to-board connection density?
SFM-104-T2-SM-D-A uses a 1.27 mm (0.050 inch) pitch that fits 8 dual-row contacts into roughly half the PCB area of an equivalent 2.54 mm pitch connector. This doubles the contact density per unit length, allowing more signal lines to route through a smaller connector zone, which is critical in FPGA module designs and compact computing hardware where board space is limited.
For test and measurement daughterboards, why choose SFM-104-T2-SM-D-A over a standard 2.54 mm header?
SFM-104-T2-SM-D-A's 1.27 mm pitch high-reliability socket contacts maintain stable electrical connections with lower crosstalk at signal frequencies up to several hundred MHz compared to 2.54 mm pitch headers. The 8-position dual-row layout provides 8 contacts in a compact footprint suitable for lab-grade measurement modules where space savings of more than 50% compared to 0.1-inch headers are needed.
What types of mating headers are compatible with SFM-104-T2-SM-D-A?
SFM-104-T2-SM-D-A mates with SAMTEC TSM, TFC, and compatible 1.27 mm pitch dual-row male pin headers with square or round pins of approximately 0.4 mm cross-section. Third-party 0.050-inch pitch male headers with 8 dual-row positions and standard pin geometry also mate reliably, provided pin length falls within the 2.5 mm to 4.0 mm insertion depth range specified for this socket series.
