Key Features
- 38-position dual-row design at 0.050" (1.27 mm) pitch delivers compact high-density SMT board interconnect
- Gold-plated contacts rated for 1 A per pin provide long-term reliability through multiple mating cycles
- STL (stand-off) variant provides controlled stacking height for precise board-to-board spacing in mezzanine assemblies
- Tape-and-reel packaging enables automated pick-and-place assembly in high-volume production environments
Applications
The SFM-119-T2-STL-D-A-K-TR is used in mezzanine stacking assemblies for FPGAs, DSP modules, and wireless communication boards where 38 signals at 0.050" pitch satisfy dense interconnect requirements without exceeding tight board-area budgets. Its stand-off feature provides a defined air gap between stacked boards, aiding thermal management in multi-board assemblies. Tape-and-reel packaging makes it appropriate for high-volume automated assembly in networking and computing hardware.

Frequently Asked Questions
What does the STL suffix in SFM-119-T2-STL-D-A-K-TR indicate about the connector's mechanical design?
The STL suffix designates a stand-off variant that incorporates mechanical posts or a raised housing to maintain a fixed air gap between the two mated PCBs. This controlled spacing, typically several millimeters, improves airflow for thermal management and ensures consistent stack height across 38-position dual-row assemblies.
How many signals can the SFM-119-T2-STL-D-A-K-TR carry, and at what current per contact?
The connector provides 38 positions across its dual-row 0.050" pitch body, with each gold-plated contact rated for approximately 1 A. This allows a mix of signal and low-power supply lines within the same 38-pin interface, reducing connector count in compact mezzanine designs.
For a DSP module stacking application, how does the 0.050" pitch of this connector compare to a 0.100" pitch alternative?
A 0.050" pitch 38-position dual-row connector occupies roughly half the board-edge footprint of an equivalent 0.100" pitch part, freeing up board real estate for bypass capacitors and high-speed signal traces on a DSP module where layout density is typically constrained to under 50 mm x 80 mm.
What tape-and-reel packaging benefit does the TR suffix of SFM-119-T2-STL-D-A-K-TR provide for volume production?
The TR (tape-and-reel) suffix means the parts are supplied in continuous reel format compatible with standard pick-and-place machines, allowing automated placement of all 38-position connectors without manual loading. This reduces per-unit assembly labor and minimizes ESD-related handling damage common in tube-supplied alternatives.
