What are the key features of SFM-127-T2-STL-D-K-TR?
- 54-position dual-row configuration on a 0.050" (1.27 mm) pitch for compact high-density mezzanine boards
- High-reliability contacts with gold plating ensuring consistent low insertion force and long service life
- Tape-and-reel SMD packaging for automated pick-and-place assembly in high-volume SMT production
What is SFM-127-T2-STL-D-K-TR used for?
The SFM-127-T2-STL-D-K-TR is designed for high-density 54-pin board-to-board interconnects in FPGA daughter cards, single-board computers, and RF front-end modules where a compact 0.050" pitch socket strip is needed. Its dual-row SMD configuration enables dense signal routing on constrained PCBs while the tape-and-reel format supports fully automated SMT assembly. The reliable mating contacts handle both low-voltage logic and analog signal paths in industrial and communications hardware.

Frequently Asked Questions
How many contact positions are available on the SFM-127-T2-STL-D-K-TR and what row arrangement does it use?
The SFM-127-T2-STL-D-K-TR provides 54 positions in a dual-row layout on a 0.050" (1.27 mm) pitch. This arrangement allows up to 54 independent signal or power connections in a surface mount footprint far more compact than equivalent 0.100" pitch alternatives, supporting dense mezzanine board designs.
How does the STL solder tail configuration of the SFM-127-T2-STL-D-K-TR influence reflow assembly quality?
The STL suffix denotes a specific solder tail length and geometry optimized for controlled coplanarity across all 54 pins at the 0.050" pitch. This ensures that during reflow soldering, all contacts land simultaneously on the PCB pads, minimizing the risk of cold or lifted solder joints. The precise coplanarity is critical on fine-pitch 0.050" footprints where a variance of even 0.1 mm can cause open circuits on 54-position connectors.
Is the SFM-127-T2-STL-D-K-TR suitable for a compact single-board computer requiring 54 signals on a restricted PCB area?
Yes, the SFM-127-T2-STL-D-K-TR is well matched for single-board computers with constrained board area. Its dual-row 0.050" pitch layout fits 54 signals into approximately 35 mm of linear board edge, roughly half the space required by a comparable 0.100" pitch connector. The SMD attachment and tape-and-reel packaging support production assembly without through-hole drilling, further maximizing usable board real estate.
